Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Ingo Molnar: "Another round of CR3/PCID related fixes (I think this addresses all but one of the known problems with PCID support), an objtool fix plus a Clang fix that (finally) solves all Clang quirks to build a bootable x86 kernel as-is" * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/asm: Fix inline asm call constraints for Clang objtool: Handle another GCC stack pointer adjustment bug x86/mm/32: Load a sane CR3 before cpu_init() on secondary CPUs x86/mm/32: Move setup_clear_cpu_cap(X86_FEATURE_PCID) earlier x86/mm/64: Stop using CR3.PCID == 0 in ASID-aware code x86/mm: Factor out CR3-building code
