Merge branch 'x86-asm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
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
