4dd3cc5caf [S390] cio: Fixup interface for setting options on ccw devices.
The current ccw_device_set_options() sets a specified mask of options
and clears those not specified, but there is no way to find out which
options have already been set.

In order to fix this up, introduce the following interface changes:

ccw_device_set_options() now only sets the specified bits, but does
not clear those that are not specified.

ccw_device_clear_options() clears the specified bits.

ccw_device_set_options_mask() provides the old semantics (setting only
the specified bits and clearing the others).

Device drivers now work as expected. qdio has been adapted.

c70555b051 [PATCH] rapidio: fix multi-switch enumeration
This patch contains two fixes for RapisIO enumeration logic:

1. Fix enumeration in configurations with multiple switches. The patch adds:

   a. Enumeration of an empty switch.  Empty switch is a switch that
      does not have any endpoint devices attached to it (except host device
      or previous switch in a chain).  New code assigns a phony destination
      ID associated with the switch and sets up corresponding routes.

   b. Adds a second pass to the enumeration to setup routes to
      devices discovered after switch was scanned.

2. Fix enumeration failure when riohdid parameter has non-zero value.
   Current version fails to setup response path to the host when it has
   destination ID other that 0.

38584c14bb [PATCH] raw: don't allow the creation of a raw device with minor number 0
Minor number 0 (under the raw major) is reserved for the rawctl device
file, which is used to query, set, and unset raw device bindings.  However,
the ioctl interface does not protect the user from specifying a raw device
with minor number 0:

$ sudo ./raw /dev/raw/raw0 /dev/VolGroup00/swap
/dev/raw/raw0:  bound to major 253, minor 2
$ ls -l /dev/rawctl
ls: /dev/rawctl: No such file or directory
$ ls -l /dev/raw/raw0
crw------- 1 root root 162, 0 Jan 12 10:51 /dev/raw/raw0
$ sudo ./raw -qa
Cannot open master raw device '/dev/rawctl' (No such file or directory)

As you can see, this prevents any further raw operations from
succeeding.  The fix (from Steve Fernandez) is quite simple--do not
allow the allocation of minor number 0.

7be2c7c96a [PATCH] RTC framework driver for CMOS RTCs
This is an "RTC framework" driver for the "CMOS" RTCs which are standard on
PCs and some other platforms.  That's MC146818 compatible silicon.
Advantages of this vs.  drivers/char/rtc.c (use one _or_ the other, only
one will be able to claim the RTC irq) include:

 - This leverages both the new RTC framework and the driver model; both
   PNPACPI and platform device modes are supported.  (A separate patch
   creates a platform device on PCs where PNPACPI isn't configured.)

 - It supports common extensions like longer alarms.  (A separate patch
   exports that information from ACPI through platform_data.)

 - Likewise, system wakeup events use "real driver model support", with
   policy control via sysfs "wakeup" attributes and and using normal rtc
   ioctls to manage wakeup.  (Patch in the works.  The ACPI hooks are
   known; /proc/acpi/alarm can vanish.  Making it work with EFI will
   be a minor challenge to someone with e.g. a MiniMac.)

It's not yet been tested on non-x86 systems, without ACPI, or with HPET.
And the RTC framework will surely have teething pains on "mainstream"
PC-based systems (though must embedded Linux systems use it heavily), not
limited to sorting out the "/dev/rtc0" issue (udev easily tweaked).  Also,
the ALSA rtctimer code doesn't use the new RTC API.

Otherwise, this should be a no-known-regressions replacement for the old
drivers/char/rtc.c driver, and should help the non-embedded distros (and
the new timekeeping code) start to switch to the framework.

Note also that any systems using "rtc-m48t86" are candidates to switch over
to this more functional driver; the platform data is different, and the way
bytes are read is different, but otherwise those chips should be compatible.

78137e3b34 [PATCH] tty: improve encode_baud_rate logic
Mostly so people can see the work in progress.  This enhances the encode
function which isn't currently used in the base tree but is when using some of
the testing tty patches.

This resolves a problem with some hardware where applications got confusing
information from the tty ioctls.  Correct but confusing.

In some situations asking for, say, 9600 baud actually gets you 9595 baud or
similar near-miss values.  With the old code this meant that a request for
B9600 got a return of BOTHER, 9595 which programs interpreted as a failure.

The new code now works on the following basis

- If you ask for specific rate via BOTHER, you get a precise return

- If you ask for a standard Bfoo rate and the result is close you get a Bfoo
  return

- If you ask for a standard Bfoo rate and get something way off you get a
  BOTHER/rate return

This seems to fix up the cases I've found where this broke compatibility.

78ba2faf71 [PATCH] IPMI: Fix some RCU problems
Fix some RCU problem pointed out by Paul McKenney of IBM.  These are:

The wholesale move of the command receivers list into a new list was not
safe because the list will point to the new tail during a traversal, so the
traversal will never end on a reader if this happens during a read.

Memory barriers were needed to handle proper ordering of the setting of the
IPMI interface as valid.  Readers might not see proper ordering of data
otherwise.

In ipmi_smi_watcher_register(), the use of the _rcu suffix on the list is
unnecessary.

This require the list_splice_init_rcu() patch previously posted.

cbcdc1debd [PATCH] PNP: export pnp_bus_type
The PNP framework doesn't export "pnp_bus_type", which is an unfortunate
exception to the policy followed by pretty much every other bus.  I noticed
this when I had to find a device in order to provide its platform_data.

Note that per advice from Arjan, the "export" scope has been been minimized to
avoid the hundred-plus bytes needed to support access from modules.  In this
case, the symbol is only needed by statically linked kernel code that lives
outside the drivers/pnp directory.

c33df4eaaf [PATCH] disable init/initramfs.c
The file init/initramfs.c is always compiled and linked in the kernel
vmlinux even when BLK_DEV_RAM and BLK_DEV_INITRD are disabled and the
system isn't using any form of an initramfs or initrd.  In this situation
the code is only used to unpack a (static) default initial rootfilesystem.
The current init/initramfs.c code.  usr/initramfs_data.o compiles to a size
of ~15 kbytes.  Disabling BLK_DEV_RAM and BLK_DEV_INTRD shrinks the kernel
code size with ~60 Kbytes.

This patch avoids compiling in the code and data for initramfs support if
CONFIG_BLK_DEV_INITRD is not defined.  Instead of the initramfs code and
data it uses a small routine in init/noinitramfs.c to setup an initial
static default environment for mounting a rootfilesystem later on in the
kernel initialisation process.  The new code is: 164 bytes of size.

The patch is separated in two parts:
1) doesn't compile initramfs code when CONFIG_BLK_DEV_INITRD is not set
2) changing all plaforms vmlinux.lds.S files to not reserve an area of
PAGE_SIZE when CONFIG_BLK_DEV_INITRD is not set.

8b6312f4dc [PATCH] vt: refactor console SAK processing
This does several things.
- It moves looking up of the current foreground console into process
  context where we can safely take the semaphore that protects this
  operation.
- It uses the new flavor of work queue processing.
- This generates a factor of do_SAK, __do_SAK that runs immediately.
- This calls __do_SAK with the console semaphore held ensuring nothing
  else happens to the console while we process the SAK operation.
- With the console SAK processing moved into process context this
  patch removes the xchg operations that I used to attempt to attomically
  update struct pid, because of the strange locking used in the SAK processing.
  With SAK using the normal console semaphore nothing special is needed.

35a17eb6a8 [SPARC64]: Add PCI MSI support on Niagara.
This is kind of hokey, we could use the hardware provided facilities
much better.

MSIs are assosciated with MSI Queues.  MSI Queues generate interrupts
when any MSI assosciated with it is signalled.  This suggests a
two-tiered IRQ dispatch scheme:

	MSI Queue interrupt --> queue interrupt handler
		MSI dispatch --> driver interrupt handler

But we just get one-level under Linux currently.  What I'd like to do
is possibly stick the IRQ actions into a per-MSI-Queue data structure,
and dispatch them form there, but the generic IRQ layer doesn't
provide a way to do that right now.

So, the current kludge is to "ACK" the interrupt by processing the
MSI Queue data structures and ACK'ing them, then we run the actual
handler like normal.

We are wasting a lot of useful information, for example the MSI data
and address are provided with ever MSI, as well as a system tick if
available.  If we could pass this into the IRQ handler it could help
with certain things, in particular for PCI-Express error messages.

The MSI entries on sparc64 also tell you exactly which bus/device/fn
sent the MSI, which would be great for error handling when no
registered IRQ handler can service the interrupt.

We override the disable/enable IRQ chip methods in sun4v_msi, so we
have to call {mask,unmask}_msi_irq() directly from there.  This is
another ugly wart.

Also, cleanup the locking issues with do_dbs_timer delayed_work callback.  As
it changes the CPU frequency using __cpufreq_target, it needs to have
policy_rwsem in write mode, which also protects it from hot plug.

* Rewrite the lock infrastructure of cpufreq using a per cpu rwsem.
* Minor restructuring of work callback in ondemand driver.
* Use the new cpufreq rwsem infrastructure in ondemand work.

This patch:

Convert policy->lock to rwsem and move it to per_cpu area.
This rwsem will protect against both changing/accessing policy

6bdd61d876 IB/mthca: Work around gcc bug on sparc64
For some reason gcc-3.4.5 on sparc64 does:

 WARNING: "____ilog2_NaN" [drivers/infiniband/hw/mthca/ib_mthca.ko] undefined!

Points to note:

 (1) The asm volatile flush/flushw are just markers for viewing what comes out
     in the assembly; removing them has no effect on the result.

 (2) Changing almost anything else in dwh__mthca_arbel_init_srq_context() or
     dwh__mthca_alloc_srq() causes the problem to go away.

The compiler command line issued by the kernel build is:

/opt/crosstool/gcc-3.4.5-glibc-2.3.6/sparc64-unknown-linux-gnu/bin/sparc64-unknown-linux-gnu-gcc -fno-strict-aliasing -fno-common -Os -m64 -mno-fpu -mcpu=ultrasparc -mcmodel=medlow -ffixed-g4 -ffixed-g5 -fcall-used-g7 -Wa,--undeclared-regs -pg -fno-omit-frame-pointer -fno-optimize-sibling-calls -fasynchronous-unwind-tables -g  -c -o drivers/infiniband/hw/mthca/.tmp_mthca_srq.o drivers/infiniband/hw/mthca/mthca_srq.c

This can be reduced to this whilst still retaining the problem:

/opt/crosstool/gcc-3.4.5-glibc-2.3.6/sparc64-unknown-linux-gnu/bin/sparc64-unknown-linux-gnu-gcc -m64 -c -o drivers/infiniband/hw/mthca/mthca_srq.o drivers/infiniband/hw/mthca/mthca_srq.c -Os

Removing -Os or changing it to -O or -O0 thru -O6 gets rid of the problem.

This patch to the kernel code fixes the problem:

839fcaba35 IPoIB: Connected mode experimental support
The following patch adds experimental support for IPoIB connected
mode, as defined by the draft from the IETF ipoib working group.  The
idea is to increase performance by increasing the MTU from the maximum
of 2K (theoretically 4K) supported by IPoIB on top of UD.  With this
code, I'm able to get 800MByte/sec or more with netperf without
options on a Mellanox 4x back-to-back DDR system.

Some notes on code:
1. SRQ is used for scalability to large cluster sizes
2. Only RC connections are used (UC does not support SRQ now)
3. Retry count is set to 0 since spec draft warns against retries
4. Each connection is used for data transfers in only 1 direction, so
   each connection is either active(TX) or passive (RX).  2 sides that
   want to communicate create 2 connections.
5. Each active (TX) connection has a separate CQ for send completions -
   this keeps the code simple without CQ resize and other tricks
6. To detect stale passive side connections (where the remote side is
   down), we keep an LRU list of passive connections (updated once per
   second per connection) and destroy a connection after it has been
   unused for several seconds. The LRU rule makes it possible to avoid
   scanning connections that have recently been active.

382a6652e9 sata_nv: use ADMA for NODATA commands
Some problems showed up recently with cache flush commands timing out on
sata_nv.  Previously these commands were always handled by transitioning to
legacy mode from ADMA mode first.  The timeout problem was worked around
already by a change to the interrupt handling code for legacy mode, but for
non-data commands like these it appears we can handle them in ADMA mode, so
the switch to legacy mode is not needed.

This patch changes the behavior so that we use ADMA mode to submit
interrupt-driven commands with ATA_PROT_NODATA protocol.  In addition to
avoiding the problem mentioned above entirely, this avoids the overhead of
switching to legacy mode and back to ADMA mode for handling cache flushes.
When handling non-DMA-mapped commands, we leave the APRD blank and clear
the NV_CPB_CTL_APRD_VALID field in the CPB so the controller does not
attempt to read it.

5bd28a4b6e sata_nv: cleanup ADMA error handling
This cleans up a few issues with the error handling in sata_nv in ADMA mode
to make it more consistent with other NCQ-capable drivers like ahci and
sata_sil24:

- When a command failed, we would effectively set AC_ERR_DEV on the
  queued command always.  In the case of NCQ commands this prevents libata
  from doing a log page query to determine the details of the failed
  command, since it thinks we've already analyzed.  Just set flags in the
  port ehi->err_mask, then freeze or abort and let libata figure out what
  went wrong.

- The code handled NV_ADMA_STAT_CPBERR as a "really bad error" which
  caused it to set error flags on every queued command.  I don't know
  exactly what this flag means (no docs, grr!) but from what I can guess
  from the standard ADMA spec, it just means that one or more of the CPBs
  had an error, so we just need to go through and do our normal checks in
  this case.

- In the error_handler function the code would always dump the state of
  all the CPBs.  This output seems redundant at this point since libata
  already dumps the state of all active commands on errors (and it also
  triggers at times when it shouldn't, like when suspending).  Take this
  out.

Follow the old SRST rule and delay 150ms between completion of

this but debounce duration could be shorter than 150ms under certain

Usefulness depends on host controller implementation but it can't hurt
and serves as a reminder that 2s delay for GoVault should also be
added here.

24dc5f33ea libata: update libata LLDs to use devres
Update libata LLDs to use devres.  Core layer is already converted to
support managed LLDs.  This patch simplifies initialization and fixes
many resource related bugs in init failure and detach path.  For
example, all converted drivers now handle ata_device_add() failure
gracefully without excessive resource rollback code.

As most resources are released automatically on driver detach, many
drivers don't need or can do with much simpler ->{port|host}_stop().
In general, stop callbacks are need iff port or host needs to be given
commands to shut it down.  Note that freezing is enough in many cases
and ports are automatically frozen before being detached.

9ac7849e35 devres: device resource management
Implement device resource management, in short, devres.  A device
driver can allocate arbirary size of devres data which is associated
with a release function.  On driver detach, release function is
invoked on the devres data, then, devres data is freed.

devreses are typed by associated release functions.  Some devreses are
better represented by single instance of the type while others need
multiple instances sharing the same release function.  Both usages are
supported.

devreses can be grouped using devres group such that a device driver
can easily release acquired resources halfway through initialization
or selectively release resources (e.g. resources for port 1 out of 4
ports).

This patch adds devres core including documentation and the following
managed interfaces.

* alloc/free	: devm_kzalloc(), devm_kzfree()
* IO region	: devm_request_region(), devm_release_region()
* IRQ		: devm_request_irq(), devm_free_irq()
* DMA		: dmam_alloc_coherent(), dmam_free_coherent(),
		  dmam_declare_coherent_memory(), dmam_pool_create(),
		  dmam_pool_destroy()
* PCI		: pcim_enable_device(), pcim_pin_device(), pci_is_managed()
* iomap		: devm_ioport_map(), devm_ioport_unmap(), devm_ioremap(),
		  devm_ioremap_nocache(), devm_iounmap(), pcim_iomap_table(),

fba6edbd3b sata_promise: handle ATAPI_NODATA ourselves
This patch extends sata_promise to handle ATAPI_NODATA
commands internally. However, commands destined to
ATA_DFLAG_CDB_INTR devices are excluded from this and
continue to be returned to libata.

Concrete changes:
- pdc_atapi_dma_pkt() is renamed to pdc_atapi_pkt(), and is
  extended to set up correct headers for NODATA packets
- pdc_qc_prep() calls pdc_atapi_pkt() for ATAPI_NODATA
- pdc_host_intr() handles ATAPI_NODATA
- pdc_qc_issue_prot() sends ATAPI_NODATA packets via the
  chip's packet mechanism, except for CDB_INTR devices

Tested on first- and second-generation chips, SATAPI and PATAPI,
with no observable regressions.

4113bb6b67 sata_promise: issue ATAPI commands as normal packets
This patch (against libata #upstream + the ATAPI cleanup patch)
reimplements sata_promise's ATAPI support to format ATAPI DMA
commands as normal packets, and to issue them via the hardware's
normal packet machinery.

It turns out that the only reason for issuing ATAPI DMA
commands via the pdc_issue_atapi_pkt_cmd() procedure was to
perform two interrupt-fiddling steps for ATA_DFLAG_CDB_INTR
devices. But these steps aren't needed because sata_promise
sets ATA_FLAG_PIO_POLLING, which disables DMA for those devices.
The remaining steps can easily be done in ATA taskfile packets.

Concrete changes:
- pdc_atapi_dma_pkt() is extended to program all packet setup
  steps, and not just contain the CDB; the sequence of steps
  exactly mirrors what pdc_issue_atapi_pkt_cmd() did
- pdc_atapi_dma_pkt() needed more parameters: simplify it by
  just passing 'qc' and having it extract the data it needs
- pdc_issue_atai_pkt_cmd() and its two helper procedures
  pdc_wait_for_drq() and pdc_wait_on_busy() are removed

Tested on first- and second-generation chips, SATAPI and PATAPI,
with no observable regressions.

95006188cb sata_promise: ATAPI support
This patch adds ATAPI support to the sata_promise driver.
This has been tested on both first- and second-generation
chips (20378 and 20575), and with both SATAPI and PATAPI
devices. CD-writing works.

SATAPI DMA works on second-generation chips, but on
first-generation chips SATAPI is limited to PIO due
to what appears to be HW limitations.
PATAPI DMA works on both first- and second-generation
chips, but requires the separate PATA support patch
before it can be used on TX2plus chips.

The functional changes to the driver are:
- remove ATA_FLAG_NO_ATAPI from PDC_COMMON_FLAGS
- add ->check_atapi_dma() operation to enable DMA for bulk data
  transfers but force PIO for other ATAPI commands; this filter
  is from Promise's driver and largely matches pata_pdc207x.c
- use a more restrictive ->check_atapi_dma() on first-generation
  chips to force SATAPI to always use PIO
- add handling of ATAPI protocols to pdc_qc_prep(), pdc_host_intr(),
  and pdc_qc_issue_prot(): ATAPI_DMA is handled by the driver
  while non-DMA protocols are handed over to libata generic code
- add pdc_issue_atapi_pkt_cmd() to handle the initial steps in
  issuing ATAPI DMA commands before sending the actual CDB;
  this procedure was ported from Promise's driver

This patch implements a simple way of setting up per-port
flags on the SATA+PATA Promise TX2plus chips, which is a
prerequisite for supporting the PATA port on those chips.

It is based on the observation that ap->flags isn't really
used until after ->port_start() has been invoked. So it
places the "exceptional" per-port flags array in the driver's
private host structure, and uses it in ->port_start() to
finalise the port's flags.

in the #all branch.

9b13b682a6 [PATCH] pata_it8213: Add new driver for the IT8213 card
Add a driver for the IT8213 which is a single channel ICH-ish PATA
controller.  As it is very different to the IT8211/2 it gets its own
driver.  There is a legacy drivers/ide driver also available and I'll post
that once I get time to test it all out (probably early January).  If
anyone else needs the drivers/ide driver and wants to do the merge for
drivers/ide (Bart ??) then I'll forward it.

da6e1a32fb [PATCH] md: avoid possible BUG_ON in md bitmap handling
md/bitmap tracks how many active write requests are pending on blocks
associated with each bit in the bitmap, so that it knows when it can clear
the bit (when count hits zero).

The counter has 14 bits of space, so if there are ever more than 16383, we
cannot cope.

Currently the code just calles BUG_ON as "all" drivers have request queue
limits much smaller than this.

However is seems that some don't.  Apparently some multipath configurations
can allow more than 16383 concurrent write requests.

So, in this unlikely situation, instead of calling BUG_ON we now wait
for the count to drop down a bit.  This requires a new wait_queue_head,
some waiting code, and a wakeup call.

Tested by limiting the counter to 20 instead of 16383 (writes go a lot slower
in that case...).

387bb17374 [PATCH] md: fix various bugs with aligned reads in RAID5
It is possible for raid5 to be sent a bio that is too big for an underlying
device.  So if it is a READ that we pass stright down to a device, it will
fail and confuse RAID5.

So in 'chunk_aligned_read' we check that the bio fits within the parameters
for the target device and if it doesn't fit, fall back on reading through
the stripe cache and making lots of one-page requests.

Note that this is the earliest time we can check against the device because
earlier we don't have a lock on the device, so it could change underneath
us.

Also, the code for handling a retry through the cache when a read fails has
not been tested and was badly broken.  This patch fixes that code.

The usage of the century bit was inverted on 2.6.19 following to PCF8563's
description, but it was not match to usage suggested by RTC8564's
datasheet.  Anyway what MO_C=1 means can vary on each platform.  This patch
is to detect its polarity in get_datetime routine.  The default value of
c_polarity is 0 (MO_C=1 means 19xx) so that this patch does not change
current behavior even if get_datetime was not called before set_datetime.

4ec031166f [PATCH] kill eth_io_copy_and_sum()
On all targets that sucker boils down to memcpy_fromio(sbk->data, from, len).
The function name is highly misguiding (it _never_ does any checksums), the
last argument is just a noise and simply expanding the call to memcpy_fromio()
gives shorter and more readable source.  For a lot of reasons it has almost
no remaining users, so it's better to just outright kill it.

4df4db5c6c [TC] dec_esp: Driver model for the PMAZ-A
This is a set of changes that converts the PMAZ-A support to the driver model.

The use of the driver model required switching to the hotplug SCSI
initialization model, which in turn required a change to the core NCR53C9x
driver.  I decided not to break all the frontend drivers and introduced an
additional parameter for esp_allocate() to select between the old and the new
model.  I hope this is OK, but I would be fine with converting NCR53C9x to the
new model unconditionally as long as I do not have to fix all the other
frontends (OK, perhaps I could do some of them ;-) ).

6b31a515e3 [TG3]: Avoid an expensive divide.
During an oprofile session of linux-2.6.20 on a dual opteron system, I noticed
an expensive divide was done in tg3_poll().

I am using gcc-4.1.1, so the following comment from drivers/net/tg3.c seems
over-optimistic :

/* Do not place this n-ring entries value into the tp struct itself,
  * we really want to expose these constants to GCC so that modulo et
  * al.  operations are done with shifts and masks instead of with
  * hw multiply/modulo instructions.  Another solution would be to
  * replace things like '% foo' with '& (foo - 1)'.
  */
#define TG3_RX_RCB_RING_SIZE(tp)        \
         ((tp->tg3_flags2 & TG3_FLG2_5705_PLUS) ?  512 : 1024)

91efa46205 ieee1394: fix host device registering when nodemgr disabled
Since my commit 8252bbb136 in 2.6.20-rc1,
host devices have a dummy driver attached.  Alas the driver was not
registered before use if ieee1394 was loaded with disable_nodemgr=1.

This resulted in non-functional FireWire drivers or kernel lockup.

0fe4c6fcac ieee1394: raw1394: prevent unloading of low-level driver
Unloading the low-level driver module of a FireWire host can lead to
all sorts of trouble if a raw1394 userspace client is using the host.
Just disallow it by incrementing the LLD's module reference count on
a RAW1394_REQ_SET_CARD write operation.  Decrement it when the file
is closed.

This feature wouldn't be relevant if "modprobe -r video1394" or
"modprobe -r dv1394" didn't automatically unload ohci1394 too.

beb2fdcad1 ieee1394: sbp2: lower block queue alignment requirement
The old setting is copy & waste from usb-storage and doesn't apply to
sbp2.  There is only 4-byte alignment required for everything, except
for S/G table elements which have to be 8-byte aligned according to the
SBP-2 spec.  (They happen to be ____cacheline_aligned in our
implementation.  Whether that's good is another question.)

We now simply don't tune block queue alignment at all.  The default
alignment would surely never become anything else than a multiple of 4,
else tons of calls to blk_queue_dma_alignment would have to be added
everywhere in drivers/...

This patch applies a little change in csr1212.c to fix iSight (firewire

also need such modification)
The actual implementation of the "csr1212_key_id_type_map" table doesn't
support some node types used by the iSight for the audio unit. This
limit makes the csr scanning routine to never see the audio unit node ,
and consequently the iSight driver probe() routine to be never called
and there is no way to hook an isight device when it is inserted.
