Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Peter Anvin: "A somewhat unpleasantly large collection of small fixes. The big ones are the __visible tree sweep and a fix for 'earlyprintk=efi,keep'. It was using __init functions with predictably suboptimal results. Another key fix is a build fix which would produce output that simply would not decompress correctly in some configuration, due to the existing Makefiles picking up an unfortunate local label and mistaking it for the global symbol _end. Additional fixes include the handling of 64-bit numbers when setting the vdso data page (a latent bug which became manifest when i386 started exporting a vdso with time functions), a fix to the new MSR manipulation accessors which would cause features to not get properly unblocked, a build fix for 32-bit userland, and a few new platform quirks" * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86, vdso, time: Cast tv_nsec to u64 for proper shifting in update_vsyscall() x86: Fix typo in MSR_IA32_MISC_ENABLE_LIMIT_CPUID macro x86: Fix typo preventing msr_set/clear_bit from having an effect x86/intel: Add quirk to disable HPET for the Baytrail platform x86/hpet: Make boot_hpet_disable extern x86-64, build: Fix stack protector Makefile breakage with 32-bit userland x86/reboot: Add reboot quirk for Certec BPC600 asmlinkage: Add explicit __visible to drivers/*, lib/*, kernel/* asmlinkage, x86: Add explicit __visible to arch/x86/* asmlinkage: Revert "lto: Make asmlinkage __visible" x86, build: Don't get confused by local symbols x86/efi: earlyprintk=efi,keep fix
