Rather than have architectures #define ARCH_HAS_SG_CHAIN in an
architecture specific scatterlist.h, make it a proper Kconfig option and
use that instead. At same time, remove the header files are are now
mostly useless and just include asm-generic/scatterlist.h.

Pull ARM updates from Russell King:
"Included in this series are:
1. BE8 (modern big endian) changes for ARM from Ben Dooks
2. big.Little support from Nicolas Pitre and Dave Martin
3. support for LPAE systems with all system memory above 4GB
4. Perf updates from Will Deacon
5. Additional prefetching and other performance improvements from Will.
6. Neon-optimised AES implementation fro Ard.
7. A number of smaller fixes scattered around the place.
There is a rather horrid merge conflict in tools/perf - I was never
notified of the conflict because it originally occurred between Will's
tree and other stuff. Consequently I have a resolution which Will
forwarded me, which I'll forward on immediately after sending this
mail.
The other notable thing is I'm expecting some build breakage in the
crypto stuff on ARM only with Ard's AES patches. These were merged
into a stable git branch which others had already pulled, so there's
little I can do about this. The problem is caused because these
patches have a dependency on some code in the crypto git tree - I
tried requesting a branch I can pull to resolve these, and all I got
each time from the crypto people was "we'll revert our patches then"
which would only make things worse since I still don't have the
dependent patches. I've no idea what's going on there or how to
resolve that, and since I can't split these patches from the rest of
this pull request, I'm rather stuck with pushing this as-is or
reverting Ard's patches.
Since it should "come out in the wash" I've left them in - the only
build problems they seem to cause at the moment are with randconfigs,
and since it's a new feature anyway. However, if by -rc1 the
dependencies aren't in, I think it'd be best to revert Ard's patches"
I resolved the perf conflict roughly as per the patch sent by Russell,
but there may be some differences. Any errors are likely mine. Let's
see how the crypto issues work out..

Use the previously unused TPIDRPRW register to store percpu offsets.
TPIDRPRW is only accessible in PL1, so it can only be used in the kernel.
This replaces 2 loads with a mrc instruction for each percpu variable
access. With hackbench, the performance improvement is 1.4% on Cortex-A9
(highbank). Taking an average of 30 runs of "hackbench -l 1000" yields:
Before: 6.2191
After: 6.1348
Will Deacon reported similar delta on v6 with 11MPCore.
The asm "memory clobber" are needed here to ensure the percpu offset
gets reloaded. Testing by Will found that this would not happen in
__schedule() which is a bit of a special case as preemption is disabled
but the execution can move cores.

In order to promote interoperability between userspace tracers and ftrace,
add a trace_clock that reports raw TSC values which will then be recorded
in the ring buffer. Userspace tracers that also record TSCs are then on
exactly the same time base as the kernel and events can be unambiguously
interlaced.
Tested: Enabled a tracepoint and the "tsc" trace_clock and saw very large
timestamp values.

Move arch-specific bits out of generic code.

As pointed out by Arnd Bergmann, this fixes a couple of issues but will
increase code size:
The original macro user_termio_to_kernel_termios was not endian safe. It
used an unsigned short ptr to access the low bits in a 32-bit word.
Both user_termio_to_kernel_termios and kernel_termios_to_user_termio are
missing error checking on put_user/get_user and copy_to/from_user.

This moves ARM over to the asm-generic/unaligned.h header. This has the
benefit of better code generated especially for ARMv7 on gcc 4.7+
compilers.
As Arnd Bergmann, points out: The asm-generic version uses the "struct"
version for native-endian unaligned access and the "byteshift" version
for the opposite endianess. The current ARM version however uses the
"byteshift" implementation for both.
Thanks to Nicolas Pitre for the excellent analysis:

In both cases the code is slightly suboptimal. One may wonder why
wasting r2 with the constant 0 in the second case for example. And all
the mov's could be folded in subsequent orr's, etc.
Now with the asm-generic version:
foo:
ldr r0, [r0, #0] @ unaligned @,* x
bx lr @
bar:
mov r3, r0 @ x, x
ldr r0, [r0, #0] @ unaligned @,* x
ldr r1, [r3, #4] @ unaligned @,
bx lr @
This is way better of course, but only because this was compiled for
ARMv7. In this case the compiler knows that the hardware can do
unaligned word access. This isn't that obvious for foo(), but if we
remove the get_unaligned() from bar as follows:
long long bar (long long *x) {return *x; }
then the resulting code is:
bar:
ldmia r0, {r0, r1} @ x,,
bx lr @
So this proves that the presumed aligned vs unaligned cases does have
influence on the instructions the compiler may use and that the above
unaligned code results are not just an accident.
Still... this isn't fully conclusive without at least looking at the
resulting assembly fron a pre ARMv6 compilation. Let's see with an
ARMv5 target:
foo:
ldrb r3, [r0, #0] @ zero_extendqisi2 @ tmp139,* x
ldrb r1, [r0, #1] @ zero_extendqisi2 @ tmp140,
ldrb r2, [r0, #2] @ zero_extendqisi2 @ tmp143,

bar:

ldrb r2, [r0, #0] @ zero_extendqisi2 @ tmp139,* x
ldrb r7, [r0, #1] @ zero_extendqisi2 @ tmp140,

orr r1, r3, r1, asl #24 @,, tmp155, tmp156,
ldmfd sp!, {r4, r5, r6, r7}

Compared to the initial results, this is really nicely optimized and I
couldn't do much better if I were to hand code it myself.

Inspired by the AArgh64 claim that it should be separate from ARM and one
reason was being able to use more asm-generic headers. Doing a diff of
arch/arm/include/asm and include/asm-generic there are numerous asm
headers which are functionally identical to their asm-generic counterparts.
Delete the ARM version and use the generic ones.
