Merge branch 'x86-asm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 asm updates from Thomas Gleixner: "The lowlevel and ASM code updates for x86: - Make stack trace unwinding more reliable - ASM instruction updates for better code generation - Various cleanups" * 'x86-asm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/entry/64: Add two more instruction suffixes x86/asm/64: Use 32-bit XOR to zero registers x86/build/vdso: Simplify 'cmd_vdso2c' x86/build/vdso: Remove unused vdso-syms.lds x86/stacktrace: Enable HAVE_RELIABLE_STACKTRACE for the ORC unwinder x86/unwind/orc: Detect the end of the stack x86/stacktrace: Do not fail for ORC with regs on stack x86/stacktrace: Clarify the reliable success paths x86/stacktrace: Remove STACKTRACE_DUMP_ONCE x86/stacktrace: Do not unwind after user regs x86/asm: Use CC_SET/CC_OUT in percpu_cmpxchg8b_double() to micro-optimize code generation
