e971290133 meth driver renovation
The meth ethernet driver for the SGI IP32 aka O2 is so far still an old
style driver which does not use the device driver model.  This is now
causing issues with some udev based gadgetry in debian-stable.  Fixed by
converting the meth driver to a platform device.

d57c4a3892 [IA64] acpi_get_sysname() should be __init
Section mismatch: reference to .init.text:acpi_find_rsdp
 (between 'acpi_get_sysname' and 'acpi_request_vector')

acpi_get_sysname() needs to call the __init function acpi_find_rsdp, but it
doesn't have the __init attribute itself, hence the warning. Luckily it is
only called from machvec_init() which has __init attribute, so the fix
is to define acpi_get_sysname() as __init too.

Currently ia64's pci_acpi_scan_root() assumes that _CRS method of root

has no resource window must be taken into account.

6ae384884d [IA64] Only unwind non-running tasks.
Unwinding a running task has proven problematic.

In one instance, the running task was attempting to unwind itself and
received an interrupt between when get_wchan allocated local variables on
the stack and when unw_init_from_blocked_task was called which resulted
in unw_init_frame_info to place this tasks task_struct pointer over the
switch stack's ar_bspstore entry.

d0aff6e6f4 x86_64: vsyscall time() fix
The vsyscall time() function basically returns the second portion of
xtime directly.  This however means that there is about a ticks worth of
time each second where time() will return a second value less then what
gettimeofday() does.

Additionally, this window where vtime() is behind vgettimeofday() grows
when dynticks is enabled, so its probably good to get this in before
dynticks lands.

Big thanks to Sripathi for noticing this issue and creating a test case
to work with!

This patch changes the vtime() implemenation to call vgettimeofday(),
much as syscall time() implementation calls gettimeofday().

d8902bfcac x86_64: early_print kernel console should send CRLF not LFCR
In
	commit d358788f3f
	Author: Russell King <rmk@dyn-67.arm.linux.org.uk>
	Date:   Mon Mar 20 20:00:09 2006 +0000

Glen Turner reported that writing LFCR rather than the more
traditional CRLF causes issues with some terminals.

Since this afflicts many serial drivers, extract the common code to a
library function (uart_console_write) and arrange for each driver to
supply a "putchar" function.

but early_printk is left out.

c824498db4 Blackfin arch: fix signal handling bug
There's a forum thread at
https://blackfin.uclinux.org/gf/project/uclinux-dist/forum/?action=ForumBrowse&_forum_action=MessageReply&message_id=24741

which has a testcase involving signal handling that crashes quite readily.
Inspecting the code I believe what happens is that signal handling can become
confused when it is invoked on return from an interrupt, if the contents of
P0 and R0 at the time of the interrupt happen to be such that P0 is larger
than zero (indicating to the signal code that we're in a syscall), and R0
happens to have a value of something like -EINTR or -ERESTARTSYS.
Fixed by setting orig_p0 to -1 if we're returning from an interrupt.  The
testcase now seems to run without problems.

6e537e9329 Blackfin arch: Fix bug using usb keyboard crashes kernel
Without conswitchp preset, we have the following situation:

 - During initcalls: con_init is called, and returns because of
   !display_desc.

 - At this point there is no memory allocated for vc_cons[].d
   A bit later vty_init calls kbd_init.

 - From now on events are passed to kbd_event which will then call
   kbd_keycode.

 - kbd_keycode will oops on a NULL pointer dereference on vc->vc_tty

e8edc6e03a Detach sched.h from mm.h
First thing mm.h does is including sched.h solely for can_do_mlock() inline
function which has "current" dereference inside. By dealing with can_do_mlock()
mm.h can be detached from sched.h which is good. See below, why.

This patch
a) removes unconditional inclusion of sched.h from mm.h
b) makes can_do_mlock() normal function in mm/mlock.c
c) exports can_do_mlock() to not break compilation
d) adds sched.h inclusions back to files that were getting it indirectly.
e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were
   getting them indirectly

Net result is:
a) mm.h users would get less code to open, read, preprocess, parse, ... if
   they don't need sched.h
b) sched.h stops being dependency for significant number of files:
   on x86_64 allmodconfig touching sched.h results in recompile of 4083 files,
   after patch it's only 3744 (-8.3%).

Cross-compile tested on

	all arm defconfigs, all mips defconfigs, all powerpc defconfigs,
	alpha alpha-up
	arm
	i386 i386-up i386-defconfig i386-allnoconfig
	ia64 ia64-up
	m68k
	mips

	um-x86_64
	x86_64 x86_64-up x86_64-defconfig x86_64-allnoconfig

This reverts commit c8fdd24725.

It turns out the kernel was correct, and the gcc complaint was a gcc
bug.  The preferred stack boundary is expressed not in bytes, but in the
the log2() of the preferred boundary, so "-mpreferred-stack-boundary=2"
is in fact exactly what we want, but a gcc that is compiled for x86-64
will consider it an error (because the 64-bit calling sequence says that
the stack should be 16-byte aligned) even if we are then using "-m32" to
generate 32-bit code.

and i386 is already calling check_pgt_cache() from the usual places,
tlb_finish_mmu() and cpu_idle() (the latter being odd, but not unusual).
flush_tlb_mm() has no business to be freeing pages: remove that line, which
sneaked in with slub's i386 support.

0aa817f078 Slab allocators: define common size limitations
Currently we have a maze of configuration variables that determine the
maximum slab size.  Worst of all it seems to vary between SLAB and SLUB.

So define a common maximum size for kmalloc.  For conveniences sake we use
the maximum size ever supported which is 32 MB.  We limit the maximum size
to a lower limit if MAX_ORDER does not allow such large allocations.

For many architectures this patch will have the effect of adding large
kmalloc sizes.  x86_64 adds 5 new kmalloc sizes.  So a small amount of
memory will be needed for these caches (contemporary SLAB has dynamically
sizeable node and cpu structure so the waste is less than in the past)

Most architectures will then be able to allocate object with sizes up to
MAX_ORDER.  We have had repeated breakage (in fact whenever we doubled the
number of supported processors) on IA64 because one or the other struct
grew beyond what the slab allocators supported.  This will avoid future
issues and f.e.  avoid fixes for 2k and 4k cpu support.

CONFIG_LARGE_ALLOCS is no longer necessary so drop it.

It fixes sparc64 with SLAB.

60e417536b [POWERPC] Pass per-file CFLAGs for platform specific op codes
As a result of compiling all of the wrapper files for every platform

c72ea777d4 [POWERPC] Small fixes for the Ebony device tree
This patch corrects a number of minor errors in the Ebony device tree:
	- Missing (given as 0) cache sizes are added to the CPU node
	- device_type properties are removed from nodes which don't
have a reasonably well defined device_type binding.  This does require
a very small code change to locate the busses to be probed for
of_platform devices by 'compatible' instead of 'device_type'.
	- A node is added for the SRAM controller
	- The unit address of the small-flash node is adjusted to
correctly reflect the reg property.
	- device_type values for the MAL and ZMII are updated to
reflected more up-to-date versions of the binding.
	- An incorrect offset in the partition map for the large-flash
node is corrected.
	- Some redundant values, already commented out are removed
entirely.

de821204db [POWERPC] Fix IO space on PCI buses created from of_platform

that it uses request_phb_iospace() for mapping the IO ports, instead
of using the dynamic hotplug stuff.  That guarantees the IO space
stays within the 2GB limit and thus doesn't break half of the legacy
drivers around.

Fixes a couple of warnings due to missing IO space while at it.

7c40542ffa [POWERPC] Fix bug adding properties with flatdevtree.c's ft_set_prop()
ft_set_prop() from flatdevtree.c in the zImage wrapper will either
replace an existing property in the flat device tree, or add a new
property definiion if the given property isn't present.

However, when adding properties, it adds the property definition
immediately before the node's END_NODE tag, potentially after any
subnode definitions for the node.  This confuses the kernel flat tree
parser in prom.c which assumes that all property definitions for a
node come before all subnode definitions.

This patch corrects ft_set_prop() so that it adds new properties
before the first subnode, instead of before the END_NODE tag.

c7754d465b [SPARC64]: Add hypervisor API negotiation and fix console bugs.
Hypervisor interfaces need to be negotiated in order to use
some API calls reliably.  So add a small set of interfaces
to request API versions and query current settings.

This allows us to fix some bugs in the hypervisor console:

1) If we can negotiate API group CORE of at least major 1
   minor 1 we can use con_read and con_write which can improve
   console performance quite a bit.

2) When we do a console write request, we should hold the
   spinlock around the whole request, not a byte at a time.
   What would happen is that it's easy for output from
   different cpus to get mixed with each other.

3) Use consistent udelay() based polling, udelay(1) each
   loop with a limit of 1000 polls to handle stuck hypervisor
   console.

311f594dec [IA64] kdump on INIT needs multi-nodes sync-up (v.2)
The current implementation of kdump on INIT events would enter
kdump processing on DIE_INIT_MONARCH_ENTER and DIE_INIT_SLAVE_ENTER
events. Thus, the monarch cpu would go ahead and boot up the kdump

On SN shub2 systems, this out-of-sync situation causes some slave
cpus on different nodes to enter POD.

This patch moves kdump entry points to DIE_INIT_MONARCH_LEAVE and
DIE_INIT_SLAVE_LEAVE. It also sets kdump_in_progress variable in
the DIE_INIT_MONARCH_PROCESS event to not dump all active stack
traces to the console in the case of kdump.

I have tested this patch on an SN machine and a HP RX2600.

This is the last remaining slab destructor in the kernel, which

As Christoph Lameter pointed out, it's potentially unsafe to be

dc2585eb47 [CPUFREQ] powernow-k7: fix MHz rounding issue with perflib
When the PST tables are broken, powernow-k7 uses ACPI's processor_perflib to
deduce the available frequency multipliers from the _PSS tables.

Upon frequency change, processor_perflib performs some verification on the
frequency (checks that it's within allowable bounds).

powernow-k7 deals with absolute frequencies in KHz, whereas perflib only
deals with MHz values. When performing the above verification, perflib
multiplies the MHz values by 1000 to obtain the KHz value.

We then end up with situations like the following:
 - powernow-k7 multiplies the multiplier by the FSB, and obtains a value
   such as 1266768 KHz
 - perflib belives the same state has frequency of 1266 MHz
 - acpi_processor_ppc_notifier calls cpufreq_verify_within_limits to verify
   that 1266768 is in the allowable range of 0 to 1266000 (i.e. 1266 * 1000)
 - it's not, so that frequency is rejected
 - the maximum CPU frequency is not reachable

This patch solves the problem by rounding up the MHz values stored in perflib's
tables. Additionally it corrects a broken URL.

It also fixes http://bugzilla.kernel.org/show_bug.cgi?id=8255 although this
case is a bit different: the frequencies in the _PSS tables are wildly wrong,
but we get better results if we force ACPI to respect the fsb * multiplier
calculations (even though it seems that the multiplier values aren't entirely
correct either).

fd4ba7e2b7 [POWERPC] Add arch/powerpc support for the Motorola PrPMC2800
This finally adds the PPC_PRPMC2800 Kconfig option, the board setup
code (the setup and reset functions) and the defconfig, to support the
Motorola PrPMC2800 platform.

c368d921da [POWERPC] Add bootwrapper support for Motorola PrPMC2800 platform
The Motorola PrPMC280 and PrPMC2800 processor modules sit on an F101 or
PrPMC2800 baseboard, respectively.  There are several variants of each
type of processor module which can have different amounts of memory,
amounts of FLASH, cpu frequencies, and an mv64360 or an mv64362.

The bootwrapper code for that platform reads VPD from an I2C EEPROM
to determine the processor module variant.  From the variant, the
amount of memory, etc. is determined and the device tree is updated
accordingly.  If the variant cannot be determined (e.g., corrupted
VPD or a previously unknown variant), the property values already
in the device tree are used.

Also, the firmware for those platforms does not completely configure
the mv64x60 host bridge so that configuration is done here.

3f456cc18f [POWERPC] Add DTS file for the Motorola PrPMC2800 platform
Add the device tree source file for the prpmc2800 line of processor PMCs.
Several of the property values are updated by the bootwrapper but sane
defaults have been chosen in case the bootwrapper can't determine the
exact processor board variant.  The defaults should allow the kernel
to boot despite having non-optimal device tree property values.

01f0e78e15 [POWERPC] Create Marvell mv64x60 I2C platform_data
This patch creates platform_device entries for the Marvell mv64x60
I2C ports, based on information contained in device tree.

This driver (like the other mv64x60 drivers) are unusual in that it
works on both the MIPS and PowerPC architectures.  Because of that,
the drivers do not support the normal PowerPC of_platform_bus_type.
They support platform_bus_type instead.
