Merge phase #1 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip
This merges phase 1 of the x86 tree, which is a collection of branches:
  x86/alternatives, x86/cleanups, x86/commandline, x86/crashdump,
  x86/debug, x86/defconfig, x86/doc, x86/exports, x86/fpu, x86/gart,
  x86/idle, x86/mm, x86/mtrr, x86/nmi-watchdog, x86/oprofile,
  x86/paravirt, x86/reboot, x86/sparse-fixes, x86/tsc, x86/urgent and
  x86/vmalloc
and as Ingo says: "these are the easiest, purely independent x86 topics
with no conflicts, in one nice Octopus merge".
