[PATCH] x86_64: mm fix x86 cpuid keys used in alternative_smp fix

[Paul Jackson <pj@sgi.com>]

From: Paul Jackson <pj@sgi.com>

The x86_64 crosstool build was failing due to:

  kernel/built-in.o(.smp_altinstructions+0x58): \
    include/asm/spinlock.h:54: undefined reference to `X86_FEATURE_UP'

This reference to X86_FEATURE_UP was added to the definition of
the alternative_smp() macro in alternative.h by the patch:
  x86_64-mm-fix-x86-cpuid-keys-used-in-alternative_smp

The alternative_smp() macro is used in spinlock.h.

The definition of X86_FEATURE_UP is in asm-x86_64/cpufeature.h.
If this is included in alternative.h, then the build succeeds.
