a8135fcfd0 [ARM] 4476/1: EM7210/SS4000E support
This patch adds the basic support for the em7210 board. It is similar to
the iq31244 board and can be found on Intel "Baxter Creek" ss4000e nas.

20c2df83d2 mm: Remove slab destructors from kmem_cache_create().
Slab destructors were no longer supported after Christoph's
c59def9f22 change. They've been
BUGs for both slab and slub, and slob never supported them
either.

This rips out support for the dtor pointer from kmem_cache_create()
completely and fixes up every single callsite in the kernel (there were
about 224, not including the slab allocator definitions themselves,
or the documentation references).

Fenghua Yu
5fb7dc37dc define new percpu interface for shared data
per cpu data section contains two types of data.  One set which is
exclusively accessed by the local cpu and the other set which is per cpu,
but also shared by remote cpus.  In the current kernel, these two sets are
not clearely separated out.  This can potentially cause the same data
cacheline shared between the two sets of data, which will result in
unnecessary bouncing of the cacheline between cpus.

One way to fix the problem is to cacheline align the remotely accessed per
cpu data, both at the beginning and at the end.  Because of the padding at
both ends, this will likely cause some memory wastage and also the
interface to achieve this is not clean.

This patch:

Moves the remotely accessed per cpu data (which is currently marked
as ____cacheline_aligned_in_smp) into a different section, where all the data
elements are cacheline aligned. And as such, this differentiates the local
only data and remotely accessed data cleanly.

83c54070ee mm: fault feedback
This patch completes Linus's wish that the fault return codes be made into
bit flags, which I agree makes everything nicer.  This requires requires
all handle_mm_fault callers to be modified (possibly the modifications
should go further and do things like fault accounting in handle_mm_fault --
however that would be for another patch).

f53f066c25 [ARM] 4451/1: pxa: make dma.c generic and remove cpu specific dma code
Since the number of dma channels varies between pxa25x and pxa27x, it
introduces some specific code in dma.c. This patch moves the specific
code to pxa25x.c and pxa27x.c and makes dma.c more generic.

1. add pxa_init_dma() for dma initialization, the number of channels
   are passed in by the argument

2. add a "prio" field to the "struct pxa_dma_channel" for the channel
   priority, and is initialized in pxa_init_dma()

3. use a general priority comparison with the channels "prio" field so
   to remove the processor specific pxa_for_each_dma_prio macro,  this
   is not lightning fast as the original one,  but it is acceptable as
   it happens when requesting dma, which is usually not so performance
   critical

486c955118 [ARM] 4434/1: PXA: remove PXA_IRQ_SKIP
1. PXA_IRQ_SKIP is defined to be 7 on PXA25x so that the first IRQ
   starts from zero. This makes IRQ numbering inconsistent between
   PXA25x and PXA27x. Remove this macro so that the same IRQ_XXXXX
   definition has the same value on both PXA25x and PXA27x.

2. make IRQ_SSP3..IRQ_PWRI2C valid only if PXA27x is defined, this
   avoids unintentional use of these macros on PXA25x

2391dae3e3 PM: introduce set_target method in pm_ops
Commit 52ade9b3b9 changed the suspend code
ordering to execute pm_ops->prepare() after the device model per-device
.suspend() calls in order to fix some ACPI-related issues.  Unfortunately, it
broke the at91 platform which assumed that pm_ops->prepare() would be called
before suspending devices.

at91 used pm_ops->prepare() to get notified of the target system sleep state,
so that it could use this information while suspending devices.  However, with
the current suspend code ordering pm_ops->prepare() is called too late for
this purpose.  Thus, at91 needs an additional method in 'struct pm_ops' that
will be used for notifying the platform of the target system sleep state.
Moreover, in the future such a method will also be needed by ACPI.

This patch adds the .set_target() method to 'struct pm_ops' and makes the
suspend code call it, if implemented, before executing the device model
per-device .suspend() calls.  It also modifies the at91 code to use
pm_ops->set_target() instead of pm_ops->prepare().

edd5cd4a94 Introduce fixed sys_sync_file_range2() syscall, implement on PowerPC and ARM
Not all the world is an i386.  Many architectures need 64-bit arguments to be
aligned in suitable pairs of registers, and the original
sys_sync_file_range(int, loff_t, loff_t, int) was therefore wasting an
argument register for padding after the first integer.  Since we don't
normally have more than 6 arguments for system calls, that left no room for
the final argument on some architectures.

Fix this by introducing sys_sync_file_range2(int, int, loff_t, loff_t) which
all fits nicely.  In fact, ARM already had that, but called it
sys_arm_sync_file_range.  Move it to fs/sync.c and rename it, then implement
the needed compatibility routine.  And stop the missing syscall check from
bitching about the absence of sys_sync_file_range() if we've implemented
sys_sync_file_range2() instead.

Tested on PPC32 and with 32-bit and 64-bit userspace on PPC64.

5d4cae5fe2 [ARM] VFP: fix section mismatch error
Fix a real section mismatch issue; the test code is thrown away after
initialisation, but if we do not detect the VFP hardware, it is left
hooked into the exception handler.  Any VFP instructions which are
subsequently executed risk calling the discarded exception handler.

Introduce a new "null" handler which returns to the "unrecognised
fault" return address.

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

516793c61b [ARM] ARMv6: add CPU_HAS_ASID configuration
Presently, we check for the minimum ARM architecture that we're
building for to determine whether we need ASID support.  This is
wrong - if we're going to support a range of CPUs which include
ARMv6 or higher, we need the ASID.

Convert the checks to use a new configuration symbol, and arrange
for ARMv6 and higher CPU entries to select it.

994c84ea52 ARM: OMAP: h4 must have blinky leds!!
This adds generic support for the "debug board" LEDs used by most of
TI's OMAP reference boards, and board-specific support for the H4.

It's derived from the not-as-generic stuff used by OMAP1 H2/H3/P2.
Those should be able to switch easily to this version, and clean up
some of the omap1-specific code.

In addition to H4 support, one key improvement is supporting not just
the "old" ARM debug LED API (with timer and idle LEDs, plus four that
can be handy for kernel debugging), but it also supports the "new"
generic LED API (most useful for usermode stuff IMO).  Either or both
APIs can be enabled.

8678c1f042 [ARM] Fix ASID version switch
Close a hole in the ASID version switch, particularly the following
scenario:

CPU0 MM PID			CPU1 MM PID
	idle
				  A	pid(A)
				  A	idle(lazy tlb)
		* new asid version triggered by B *
  B	pid(B)
  A	pid(A)
		* MM A gets new asid version *
  A	idle(lazy tlb)
				  A	pid(A)
		* CPU1 doesn't see the new ASID *

The result is that CPU1 continues running with the hardware set
for the original (stale) ASID value, but mm->context.id contains
the new ASID value.  The result is that the next MM fault on CPU1
updates the page table entries, but flush_tlb_page() fails due to
wrong ASID.

There is a related case with a threaded application is allocated
a new ASID on one CPU while another of its threads is running on
some different CPU.  This scenario is not fixed by this commit.

1eeb66a1bb move die notifier handling to common code
This patch moves the die notifier handling to common code.  Previous
various architectures had exactly the same code for it.  Note that the new
code is compiled unconditionally, this should be understood as an appel to
the other architecture maintainer to implement support for it aswell (aka
sprinkling a notify_die or two in the proper place)

arm had a notifiy_die that did something totally different, I renamed it to
arm_notify_die as part of the patch and made it static to the file it's
declared and used at.  avr32 used to pass slightly less information through
this interface and I brought it into line with the other architectures.

3603ab2b62 [ARM] mm 10: allow memory type to be specified with ioremap
__ioremap() took a set of page table flags (specifically the cacheable
and bufferable bits) to control the mapping type.  However, with
the advent of ARMv6, this is far too limited.

Replace the page table flags with a memory type index, so that the
desired attributes can be selected from the mem_type table.

Finally, to prevent silent miscompilation due to the differing
arguments, rename the __ioremap() and __ioremap_pfn() functions.

11a78b7944 ARM: OMAP: MPUIO wake updates
GPIO and MPUIO wake updates:

 - Hook MPUIOs into the irq wakeup framework too.  This uses a platform
   device to update irq enables during system sleep states, instead of
   a sys_device, since the latter is no longer needed for such things.

 - Also forward enable/disable irq wake requests to the relevant GPIO
   controller, so the top level IRQ dispatcher can (eventually) handle
   these wakeup events automatically if more than one GPIO pin needs to
   be a wakeup event source.

 - Minor tweak to the 24xx non-wakeup gpio stuff: no need to check such
   read-only data under the spinlock.

This assumes (maybe wrongly?) that only 16xx can do GPIO wakeup; without
a 15xx I can't test such stuff.

Also this expects the top level IRQ dispatcher to properly handle requests
to enable/disable irq wake, which is currently known to be wrong:  omap1
saves the flags but ignores them, omap2 doesn't even save it.  (Wakeup
events are, wrongly, hardwired in the relevant mach-omapX/pm.c file ...)
So MPUIO irqs won't yet trigger system wakeup.

4043579252 [ARM] 4227/1: minor head.S fixups
Let's surround constructs like:

	orr	r3, r3, #(KERNEL_RAM_PADDR & 0x00f00000)

between .if .endif since (KERNEL_RAM_PADDR & 0x00f00000) is 0 in 99% of
all cases.

Also let's mask PHYS_OFFSET with 0x00f00000 instead of 0x00e00000.
Section mappings are really 1MB not 2MB and the 2MB groupping is
a higher level issue already much better enforced with

#if (PHYS_OFFSET & 0x001fffff)
#error "PHYS_OFFSET must be at an even 2MiB boundary!"
#endif

at the top of the file.

e90ddd813d [ARM] 4348/4: iop3xx: Give Linux control over PCI initialization
Currently the iop3xx platform support code assumes that RedBoot is the
bootloader and has already initialized the ATU.  Linux should handle this
initialization for three reasons:

1/ The memory map that RedBoot sets up is not optimal (page_to_dma and
virt_to_phys return different addresses).  The effect of this is that using
the dma mapping API for the internal bus dma units generates pci bus
addresses that are incorrect for the internal bus.

2/ Not all iop platforms use RedBoot

3/ If the ATU is already initialized it indicates that the iop is an add-in
card in another host, it does not own the PCI bus, and should not be
re-initialized.

Changelog:
* rather than change nr_controllers to zero, simply do not call
  pci_common_init

(This was under Xen, but there's no reason it couldn't happen on bare

This patch mallocs the local variables, thereby reducing the stack
usage to sane levels.

Also, up the heap size for the kernel decompressor to deal with the
extra allocation.

e8c9c50269 power management: implement pm_ops.valid for everybody
Almost all users of pm_ops only support mem sleep, don't check in .valid and
don't reject any others in .prepare so users can be confused if they check
/sys/power/state, especially when new states are added (these would then
result in s-t-r although they're supposed to be something different).

This patch implements a generic pm_valid_only_mem function that is then
exported for users and puts it to use in almost all existing pm_ops.

fe0c935a6c rework pm_ops pm_disk_mode, kill misuse
This patch series cleans up some misconceptions about pm_ops.  Some users of
the pm_ops structure attempt to use it to stop the user from entering suspend
to disk, this, however, is not possible since the user can always use
"shutdown" in /sys/power/disk and then the pm_ops are never invoked.  Also,
platforms that don't support suspend to disk simply should not allow
configuring SOFTWARE_SUSPEND (read the help text on it, it only selects
suspend to disk and nothing else, all the other stuff depends on PM).

The pm_ops structure is actually intended to provide a way to enter
platform-defined sleep states (currently supported states are "standby" and
"mem" (suspend to ram)) and additionally (if SOFTWARE_SUSPEND is configured)
allows a platform to support a platform specific way to enter low-power mode
once everything has been saved to disk.  This is currently only used by ACPI
(S4).

This patch:

The pm_ops.pm_disk_mode is used in totally bogus ways since nobody really
seems to understand what it actually does.

This patch clarifies the pm_disk_mode description.

It also removes all the arm and sh users that think they can veto suspend to
disk via pm_ops; not so since the user can always do echo shutdown >
/sys/power/disk, they need to find a better way involving Kconfig or such.

ACPI is the only user left with a non-zero pm_disk_mode.

The patch also sets the default mode to shutdown again, but when a new pm_ops
is registered its pm_disk_mode is selected as default, that way the default
stays for ACPI where it is apparently required.

git grep "struct __initdata" revealed that board-sam9260.c had the same

This patch fixes this by placing the __initdata marker correct.  It was
checked with objdump that the variable was moved to .init.data by this
change.

Fixed an unrelated section mismatch warning while touching the file.

7053acbd78 [ARM] 4304/1: removes the unnecessary bit number from CKENnn_XXXX
This patch removes the unnecessary bit number from CKENnn_XXXX
definitions for PXA, so that

	CKEN0_PWM0 --> CKEN_PWM0
	CKEN1_PWM1 --> CKEN_PWM1
	...
	CKEN24_CAMERA --> CKEN_CAMERA

The reasons for the change of these defitions are:

1. they do not scale - they are currently valid for pxa2xx, but
definitely not valid for pxa3xx, e.g., pxa3xx has bit 3 for camera
instead of bit 24

2. they are unnecessary - the peripheral name within the definition
has already announced its usage, we don't need those bit numbers
to know which peripheral we are going to enable/disable clock for

3. they are inconvenient - think about this: a driver programmer
for pxa has to remember which bit in the CKEN register to turn
on/off

Another change in the patch is to make the definitions equal to its
clock bit index, so that

   #define CKEN_CAMERA  (24)

instead of

   #define CKEN_CAMERA  (1 << 24)

this change, however, will add a run-time bit shift operation in
pxa_set_cken(), but the benefit of this change is that it scales
when bit index exceeds 32, e.g., pxa3xx has two registers CKENA
and CKENB, totally 64 bit for this, suppose CAMERA clock enabling
bit is CKENB:10, one can simply define CKEN_CAMERA to be (32 + 10)
and so that pxa_set_cken() need minimum change to adapt to that.

4a56c1e41f [ARM] mm 3: separate out supersection mappings, avoid for <4GB
Catalin Marinas at ARM Ltd says:
> The CPU architects in ARM intended supersections only as a way to map
> addresses >= 4GB. Supersections are not mandated by the architecture
> and there is no easy way to detect their hardware support at run-time
> (other than checking for a specific core). From the analysis done in

Therefore, we should avoid using supersections unless there's a real
need (iow, we're mapping addresses >= 4GB).

This means that we can simplify create_mapping() a bit since we will
only use supersection mappings for addresses >= 4GB, which means that
the physical, virtual and length must be multiples of the supersection
mapping size.

28735a7253 [PATCH] gpio_direction_output() needs an initial value
It's been pointed out that output GPIOs should have an initial value, to
avoid signal glitching ...  among other things, it can be some time before
a driver is ready.  This patch corrects that oversight, fixing

 - documentation
 - platforms supporting the GPIO interface
 - users of that call (just one for now, others are pending)

There's only one user of this call for now since most platforms are still
using non-generic GPIO setup code, which in most cases already couples the
initial value with its "set output mode" request.

Note that most platforms are clear about the hardware letting the output
value be set before the pin direction is changed, but the s3c241x docs are
vague on that topic ...  so those chips might not avoid the glitches.

0a938b9768 [PATCH] add CONFIG_GENERIC_GPIO
Most drivers using GPIOs already know they are running on a system that
supports the generic GPIO calls, because of other platform dependencies.
But the generic GPIO-based LED and input button drivers can't know that.

So this patch adds a Kconfig hook, GENERIC_GPIO, to mark the platforms
where <asm/gpio.h> will do the right thing.  Currently that's a bunch of
ARMs, and AVR32; more are on the way.

It also fixes a dependency bug for the gpio button input driver; it was
wrong to start with, now it covers all platforms with GENERIC_GPIO.

ef557d76df ARM: OMAP: correct misc 15xx and non-15xx platform code
Disable accesses to SOFT_REQ_REG2 and ULPD_SOFT_DISABLE_REQ_REG
registers for 15xx processors that don't have these registers. Enable
level 2 interrupt handler for processors that identify as OMAP 15xx
(e.g 310) and not 1510 specifically. Also fix the following compiler
warning (only visible with CONFIG_OMAP_RESET_CLOCKS):

arch/arm/mach-omap1/clock.c: In function 'omap1_clk_disable_unused':
arch/arm/mach-omap1/clock.c:634: warning: 'return' with a value, in
function returning void
