* 'x86-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:
  x86, irq: Allow 0xff for /proc/irq/[n]/smp_affinity on an 8-cpu system
  Makefile: Unexport LC_ALL instead of clearing it
  x86: Fix objdump version check in arch/x86/tools/chkobjdump.awk
  x86: Reenable TSC sync check at boot, even with NONSTOP_TSC
  x86: Don't use POSIX character classes in gen-insn-attr-x86.awk
  Makefile: set LC_CTYPE, LC_COLLATE, LC_NUMERIC to C
  x86: Increase MAX_EARLY_RES; insufficient on 32-bit NUMA
  x86: Fix checking of SRAT when node 0 ram is not from 0
  x86, cpuid: Add "volatile" to asm in native_cpuid()
  x86, msr: msrs_alloc/free for CONFIG_SMP=n
  x86, amd: Get multi-node CPU info from NodeId MSR instead of PCI config space
  x86: Add IA32_TSC_AUX MSR and use it
  x86, msr/cpuid: Register enough minors for the MSR and CPUID drivers
  initramfs: add missing decompressor error check
  bzip2: Add missing checks for malloc returning NULL
  bzip2/lzma/gzip: pre-boot malloc doesn't return NULL on failure
