Patch from Lennert Buytenhek
This patch adds support for the Ajeco 1ARM Single Board Computer, a
VME form factor SBC based on the Atmel AT91 SoC, with 64M RAM, seven
serial ports, three ethernet ports, IDE, CF, USB host and device,
and S-Video/VGA out.--

The wrapper routines are required when asmlinkage differs from the usual
calling convention. So we need to have them. However, by rearranging
the parameters, they will get optimised away to a single jump for most
people.

Up until now algorithms have been happy to get a context pointer since
they know everything that's in the tfm already (e.g., alignment, block
size).
However, once we have parameterised algorithms, such information will
be specific to each tfm. So the algorithm API needs to be changed to
pass the tfm structure instead of the context pointer.
This patch is basically a text substitution. The only tricky bit is
the assembly routines that need to get the context pointer offset
through asm-offsets.h.

Various digest algorithms operate one block at a time and therefore
keep a temporary buffer of partial blocks. This buffer does not need
to be initialised since there is a counter which indicates what is and
isn't valid in it.

The wrappers aes_encrypt/aes_decrypt simply reverse the order of the
function arguments. It's just as easy to get the actual assembly code
to read them in the opposite order.

Here is a patch to the system call handling for 5307/5272/etc to:
- fix the strace support (one tested the wrong bit)
- make all system calls a little bit faster by inlining set_esp0 and
supporting ENOSYS out of the critical path.
- remove extraneous spaces

This patch will fix a boot memory reservation bug that trashes memory on
the ES7000 when loading the kdump crash kernel.
The code in arch/x86_64/kernel/setup.c to reserve boot memory for the crash
kernel uses the non-numa aware "reserve_bootmem" function instead of the
NUMA aware "reserve_bootmem_generic". I checked to make sure that no other
function was using "reserve_bootmem" and found none, except the ones that
had NUMA ifdef'ed out.
I have tested this patch only on an ES7000 with NUMA on and off (numa=off)
in a single (non-NUMA) and multi-cell (NUMA) configurations.

As described in a previous patch and documented in mm/filemap.h,
copy_from_user_inatomic* shouldn't zero out the tail of the buffer after an
incomplete copy.
This patch implements that change for i386.
For the _nocache version, a new __copy_user_intel_nocache is defined similar
to copy_user_zeroio_intel_nocache, and this is ultimately used for the copy.
For the regular version, __copy_from_user_ll_nozero is defined which uses
__copy_user and __copy_user_intel - the later needs casts to reposition the
__user annotations.
If copy_from_user_atomic is given a constant length of 1, 2, or 4, then we do
still zero the destintion on failure. This didn't seem worth the effort of
fixing as the places where it is used really don't care.

This patch contains a total rewrite of the backlight infrastructure for
portable Apple computers. Backward compatibility is retained. A sysfs
interface allows userland to control the brightness with more steps than
before. Userland is allowed to upload a brightness curve for different
