      x86, kvm: Fix section mismatches in kvm.c · d3ac8815
      Rakib Mullick authored 
      The function paravirt_ops_setup() has been refering the
variable no_timer_check, which is a __initdata. Thus generates
the following warning. paravirt_ops_setup() function is called
from kvm_guest_init() which is a __init function. So to fix
this we mark paravirt_ops_setup as __init.

The sections-check output that warned us about this was:

   LD      arch/x86/built-in.o
  WARNING: arch/x86/built-in.o(.text+0x166ce): Section mismatch in
  reference from the function paravirt_ops_setup() to the variable
  .init.data:no_timer_check
  The function paravirt_ops_setup() references
  the variable __initdata no_timer_check.
  This is often because paravirt_ops_setup lacks a __initdata
  annotation or the annotation of no_timer_check is wrong.

      x86: Add missing annotation to arch/x86/lib/copy_user_64.S::copy_to_user · 3fd382ce
      Mike Galbraith authored 
      While examining symbol generation in perf_counter tools, I
noticed that copy_to_user() had no size in vmlinux's symtab.

      x86: Fix fixmap page order for FIX_TEXT_POKE0,1 · 12b9d7cc
      Mathieu Desnoyers authored 
      Masami reported:

> Since the fixmap pages are assigned higher address to lower,

> to FIX_TEXT_POKE0).

I prefer to just invert the order of the fixmap declaration.
It's simpler and more straightforward.

Backward fixmaps seems to be used by both x86 32 and 64.

It's really rare but a nasty bug, because it only hurts when
instructions to patch are crossing a page boundary. If this
happens, the fixmap write accesses will spill on the following
fixmap, which may very well crash the system. And this does not
crash the system, it could leave illegal instructions in place.
Thanks Masami for finding this.

It seems to have crept into the 2.6.30-rc series, so this calls
for a -stable inclusion.

Improve the code to be saner and simpler and just print out
the bitfield in a single line using hexa values - not as a
(rather pointless) binary bitfield.

Partially reused Linus's initial fix for this.
