New arch macro STACK_TOP_MAX it gives the larges valid stack address for the
architecture in question.It differs from STACK_TOP in that it will not distinguish between
personalities but will always return the largest possible address.This is used to create the initial stack on execve, which we will move down to
the proper location once the binfmt code has figured out where that is.Signed-off-by: Peter Zijlstra

These functions depend on "result" being initalized to 0, but "result"
is not included as an input constraint to the inline assembly block
following its initialization, only as an output constraint. Thus gcc
thinks it doesn't need to initialize it, so result ends up undefined
if the "unless" condition is true.This fixes an oops in sunrpc where the faulty atomics caused
rpciod_up() to not start the workqueue as it should.Signed-off-by: Haavard Skinnemoen

If we let unaligned word loads bypass the generic unaligned handling,
gcc may combine it with a swap.b instruction and turn it into a ldwsp
instruction, which does not work with unaligned addresses.Revert the optimization to prevent the RNDIS driver from crashing.
Hopefully we'll figure something out later (it may be better to do the
optimization in gcc.)Signed-off-by: Haavard Skinnemoen

Split the SM platform device into separate platform devices for PM,
RTC, WDT and EIC. This is more correct according to the documentation
and allows us to simplify the code a little.Also turn the EIC driver into a real platform driver.

Use a more conventional implementation for unaligned access, and include
an AT32AP-specific optimization: the CPU will handle unaligned words.The result is always faster and smaller for 8, 16, and 32 bit values.
For 64 bit quantities, it's presumably larger.Signed-off-by: David Brownell

AVR32: Spinlock initializer cleanup
[AVR32] Use correct config symbol when setting cpuflags -
Several drivers shared between AT91 and AVR32 chips use cpu_is_xxx()
to handle CPU-specific differences. Currently, such code needs to be
inside #ifdef CONFIG_ARCH_AT91 because the macros don't exist on AVR32.By defining the same macros on both AT91 and AVR32, these #ifdefs can
be eliminated. Since the macros will evaluate to a constant value for
CPUs that aren't supported by the current architecture, any code that
is only needed on AT91 will be optimized away on AVR32 and vice versa.Signed-off-by: Haavard Skinnemoen

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.[akpm@linux-foundation.org: build fix]

Add hooks to allow a paravirt implementation to track the lifetime of
an mm. Paravirtualization requires three hooks, but only two are
needed in common code. They are:arch_dup_mmap, which is called when a new mmap is created at fork
arch_exit_mmap, which is called when the last process reference to an
mm is dropped, which typically happens on exit and exec.The third hook is activate_mm, which is called from the arch-specific
activate_mm() macro/function, and so doesn't need stub versions for
other architectures. It's called when an mm is first used.Signed-off-by: Jeremy Fitzhardinge

gcc 4.1 doesn't seem to like const variables as inline assembly
outputs. Drop support for reading 64-bit values using get_user() so

i386, doesn't support reading 64-bit values with get_user().Signed-off-by: Haavard Skinnemoen
