Pull asm/x86 changes from Ingo Molnar:
"Misc changes, with a bigger processor-flags cleanup/reorganization by
Peter Anvin"
* 'x86-asm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86, asm, cleanup: Replace open-coded control register values with symbolic
x86, processor-flags: Fix the datatypes and add bit number defines
x86: Rename X86_CR4_RDWRGSFS to X86_CR4_FSGSBASE
x86, flags: Rename X86_EFLAGS_BIT1 to X86_EFLAGS_FIXED
linux/const.h: Add _BITUL() and _BITULL()
x86/vdso: Convert use of typedef ctl_table to struct ctl_table
x86: __force_order doesn't need to be an actual variable
