      x86, UV: Update node controller MMRs · 62b0cfc2
      Jack Steiner authored 
      A new version of the SGI UV hub node controller is being
developed. A few of the MMRs (control registers) that exist on
the current hub no longer exist on the new hub. Fortunately,
there are alternate MMRs that are are functionally equivalent
and that exist on both hubs.

This patch changes the UV code to use MMRs that exist in BOTH
versions of the hub node controller.

      x86: Remove unnecessary casts of void ptr returning alloc function return values · 8e5e9521
      Jesper Juhl authored 
      The [vk][cmz]alloc(_node) family of functions return void
pointers which it's completely unnecessary/pointless to cast to
other pointer types since that happens implicitly.

This patch removes such casts from arch/x86.

      x86: Address gcc4.6 "set but not used" warnings in apic.h · 0059b243
      Andi Kleen authored 
      native_apic_msr_read() and x2apic_enabled() use rdmsr(msr, low, high),
but only use the low part.

gcc4.6 complains about this:
.../apic.h:144:11: warning: variable 'high' set but not used [-Wunused-but-set-variable]

rdmsr() is just a wrapper around rdmsrl() which splits the 64bit value
into low and high, so using rdmsrl() directly solves this.

[tglx: Changed the variables to u64 as suggested by Cyrill. It's less
       confusing and has no code impact as this is 64bit only anyway.
       Massaged changelog as well. ]

      x86, mm: Fix section mismatch in tlb.c · cf38d0ba
      Rakib Mullick authored 
      Mark tlb_cpuhp_notify as __cpuinit. It's basically a callback
function, which is called from __cpuinit init_smp_flash(). So -
it's safe.

We were warned by the following warning:

 WARNING: arch/x86/mm/built-in.o(.text+0x356d): Section mismatch
 in reference from the function tlb_cpuhp_notify() to the
 function .cpuinit.text:calculate_tlb_offset()
 The function tlb_cpuhp_notify() references
 the function __cpuinit calculate_tlb_offset().
 This is often because tlb_cpuhp_notify lacks a __cpuinit
 annotation or the annotation of calculate_tlb_offset is wrong.
