Pull x86/asmlinkage changes from Ingo Molnar:
 "As a preparation for Andi Kleen's LTO patchset (link time
  optimizations using GCC's -flto which build time optimization has
  steadily increased in quality over the past few years and might
  eventually be usable for the kernel too) this tree includes a handful
  of preparatory patches that make function calling convention
  annotations consistent again:

   - Mark every function without arguments (or 64bit only) that is used
     by assembly code with asmlinkage()

   - Mark every function with parameters or variables that is used by
     assembly code as __visible.

  For the vanilla kernel this has documentation, consistency and
  debuggability advantages, for the time being"
