4e834da1da ieee1394: schedule *_oui sysfs attributes for removal
There is no manpower available to reform oui.db into a library for use
in more kernel subsystems.  The low ratio of usefulness to size and the
occasional need to update oui.db from IEEE's official list suggest to
drop oui.db.  I plan to make a userspace script available which
translates the remaining numeric sysfs attributes to names of
organizations.

66743e061f ieee1394: sbp2: remove irritating log message
The queue depth can be read from /sys/bus/scsi/devices/*/queue_depth,
so don't log it.  And the hint about speed improvements is misleading,
at least under current kernels.  If serialization is switched off, read
performance is typically increased by less than 10%.  (I did not test
write performance recently.)  On the other hand, serialize_io=0 is not
yet safe due to some implementation issues that are not trivial to fix.

b07375b155 ieee1394: nodemgr: revise semaphore protection of driver core data
- The list "struct class.children" is supposed to be protected by
   class.sem, not by class.subsys.rwsem.

 - nodemgr_remove_uds() iterated over nodemgr_ud_class.children without
   proper protection.  This was never observed as a bug since the code
   is usually only accessed by knodemgrd.  All knodemgrds are currently
   globally serialized.  But userspace can trigger this code too by
   writing to /sys/bus/ieee1394/destroy_node.

 - Clean up access to the FireWire bus type's subsys.rwsem:  Access it
   uniformly via ieee1394_bus_type.  Shrink rwsem protected regions
   where possible.  Expand them where necessary.  The latter wasn't a
   problem so far because knodemgr is globally serialized.

This should harden the interaction of ieee1394 with sysfs and lay ground
for deserialized operation of multiple knodemgrds and for implementation
of subthreads for parallelized scanning and probing.

video1394 does not need to take the BKL. The data structures shared between
file_operations and interrupts are already protected through context-specific
spinlocks.

The only other danger is video1394_release() being called during another

when the last thread has closed the fd.

f011bf085c ohci1394: steps to implement suspend/resume
I did a quick shot on what I described and the appended patch
does the first thing needed for working suspend/resume
in ohci1394 which is HW de- and re-initialisation.

It works with suspend2disk on my Ricoh R5C552 IEEE 1394 Controller
with the 2.6.17 kernel to the extent that if I call dvgrab --interactive
after suspend2disk without unloading ohci1394, it does not lock up
dvgrab with 100% CPU but properly connects to the camera, given
that I first unplug and plug the camera after coming back from
suspend.

I guess that could be fixed by forcing a bus reset in the resume
function.

I cannot test suspend to RAM here at the moment and should
follow the guidelines in Documentation/power/pci.txt also,
so this is rather a quick report than a finished patch and
there are some rough edges:

However, with this patch, I have to unload at least some in-kernel
users of ohci1394 like dv1394 or video1394 before suspending.

Not doing that caused an Oops and a bad tasklet error, probably from
not handling ISO tasklets during suspend/resume properly.

Maybe these can be temporarily cleared or unregistered and
re-registered for suspend/resume with help from the other
layers or from the highlevel 1394 core, but I do not really
know what these do.

But this patch provides a useful base to start from and is
already of much help for people which do not need dv1394
and video1394 or can unload them at least during suspend.

I cannot test function with sbp2 at the moment, but raw1394
seems to work fine.

68380b5813 Add "run_scheduled_work()" workqueue function
This allows workqueue users to run just their own pending work, rather
than wait for the whole workqueue to finish running.  This solves the
deadlock with networking libphy that was due to other workqueue entries
possibly needing a lock that was held by the routine that wanted to
flush its own work.

It's not wonderful: if you absolutely need to synchronize with the work
function having been executed, any user strictly speaking should have
its own completion tracking logic, since when we run things explicitly
by hand, the generic workqueue layer can no longer help us synchronize.

Also, this is strictly only usable for work that has been scheduled
without any delayed timers.  You can not mix the new interface with
schedule_delayed_work().

But it's better than what we had currently.

285f5fa7e9 [ARM] 3995/1: iop13xx: add iop13xx support
The iop348 processor integrates an Xscale (XSC3 512KB L2 Cache) core with a
Serial Attached SCSI (SAS) controller, multi-ported DDR2 memory
controller, 3 Application Direct Memory Access (DMA) controllers, a 133Mhz
PCI-X interface, a x8 PCI-Express interface, and other peripherals to form
a system-on-a-chip RAID subsystem engine.

The iop342 processor replaces the SAS controller with a second Xscale core
for dual core embedded applications.

The iop341 processor is the single core version of iop342.

This patch supports the two Intel customer reference platforms iq81340mc
for external storage and iq81340sc for direct attach (HBA) development.

4d7cbac7c8 [PATCH] IPMI: Fix BT long busy
The IPMI BT subdriver has been patched to survive "long busy" timeouts seen
during firmware upgrades and resets.  The patch never returns the HOSED state,
synthesizes response messages with meaningful completion codes, and recovers
gracefully when the hardware finishes the long busy.  The subdriver now issues
a "Get BT Capabilities" command and properly uses those results.  More
informative completion codes are returned on error from transaction starts;
this logic was propogated to the KCS and SMIC subdrivers.  Finally, indent and
other style quirks were normalized.

55162fb165 [PATCH] IPMI: fix request events
When the IPMI message handler requested that the interface look for events,
the ipmi_si driver would request flags, see if the event buffer full flag was
set, then request events.  It's better to just send the request for events, as
it cuts one message out of the transaction if there happens to be events, and
it will fetch events even if the event buffer was not full.

Some commands and operations on a BMC can cause the BMC to "go away" for a

nature to timeout and generate annoying logs, or possibly cause other bad
things to happen when in firmware update mode.

Add detection of those commands (cold reset, warm reset, and any firmware
command) and turns off automatic processing for 30 seconds.  It also add a

The pl010 primecell documentation specifies that an error indicated via RSR
should be cleared by a write to ECR.  We didn't do this, which was causing
errors to be re-reported on every call to pl010_rx_chars().

Doing a write to ECR once we detect an error appears to prevent the ep93xx
console UART driver from going into a mode where it reports "ttyAM0: X
input overrun(s)" every couple of keystrokes.

db68b189f4 [PATCH] add rtc-omap driver
This creates a new RTC-framework driver for the RTC/calendar module found
in various OMAP1 chips.  (OMAP2 and OMAP3 use external RTCs, like those in
TI's multifunction PM companion chips.) It's been in the Linux-OMAP tree
for several months now, and other trees before that, so it's quite stable.
The most notable issue is that the OMAP IRQ code doesn't yet support the
RTC IRQ as a wakeup event.  Once that's fixed, a patch will be needed.

da015a6744 [PATCH] agp-amd64: section mismatches with HOTPLUG=n
When CONFIG_HOTPLUG=n, agp_amd64_resume() calls nforce3_agp_init(), which is
__devinit == __init, so has been discarded and is not usable for resume.

WARNING: drivers/char/agp/amd64-agp.o - Section mismatch: reference to .init.text: from .text between 'agp_amd64_resume' (at offset 0x249) and 'amd64_tlbflush'

4438982f56 [PATCH] parport: section mismatches with HOTPLUG=n
When CONFIG_HOTPLUG=n, parport_pc calls some __devinit == __init code that
could be discarded.  These calls are made from parport_irq_probe(), which is
called from parport_pc_probe_port(), which is an exported symbol, so the calls
could (possibly) happen after init time.

0231606785 [PATCH] hotplug CPU: clean up hotcpu_notifier() use
There was lots of #ifdef noise in the kernel due to hotcpu_notifier(fn,
prio) not correctly marking 'fn' as used in the !HOTPLUG_CPU case, and thus
generating compiler warnings of unused symbols, hence forcing people to add
#ifdefs.

the compiler can skip truly unused functions just fine:

    text    data     bss     dec     hex filename
