Merge branch 'x86-xsave-for-linus' of git://git./linux/kernel/git/tip/linux-2.6-tip

* 'x86-xsave-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:
  x86, xsave: Make xstate_enable_boot_cpu() __init, protect on CPU 0
  x86, xsave: Add __init attribute to setup_xstate_features()
  x86, xsave: Make init_xstate_buf static
  x86, xsave: Check cpuid level for XSTATE_CPUID (0x0d)
  x86, xsave: Introduce xstate enable functions
  x86, xsave: Separate fpu and xsave initialization
  x86, xsave: Move boot cpu initialization to xsave_init()
  x86, xsave: 32/64 bit boot cpu check unification in initialization
  x86, xsave: Do not include asm/i387.h in asm/xsave.h
  x86, xsave: Use xsaveopt in context-switch path when supported
  x86, xsave: Sync xsave memory layout with its header for user handling
  x86, xsave: Track the offset, size of state in the xsave layout
