nmi_create_files() in arch/i386/oprofile/nmi_int.c depends on
model->num_counters (number of performance counters) being less than 10.
While this is currently the case, it's too clever by half.Other archs aren't quite as clever: they assume 100. I suggest to
normalize them all to 1000.Cc: Philippe Elie

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 spacesSigned-off-by: Greg Ungerer

A cleanup of m68knommu/kernel/setup.c :
- No need to initialize global pointers to NULL, they will have that value
automatically, and they eat up space in my data segment image in FLASH.

Switch to naming the architecture config options for the m68knommu branch
as "M68K", dropping "M68KNOMMU". The CONFIG_MMU separates the 2 now, and
the m68knommu branch is still strictly speaking an M68K (including the
ColdFire parts).Signed-off-by: Greg Ungerer

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.Signed-off-by: Amul Shah

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.Signed-off-by: Neil Brown

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
monitors, similar to Mac OS X.[akpm@osdl.org: add needed exports]
