    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/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
