    Linus Torvalds authored
    Pull x86 asm changes from Ingo Molnar:
     "There were lots of changes in this development cycle:
    
       - over 100 separate cleanups, restructuring changes, speedups and
         fixes in the x86 system call, irq, trap and other entry code, part
         of a heroic effort to deobfuscate a decade old spaghetti asm code
         and its C code dependencies (Denys Vlasenko, Andy Lutomirski)
    
       - alternatives code fixes and enhancements (Borislav Petkov)
    
       - simplifications and cleanups to the compat code (Brian Gerst)
    
       - signal handling fixes and new x86 testcases (Andy Lutomirski)
    
       - various other fixes and cleanups
    
      By their nature many of these changes are risky - we tried to test
      them well on many different x86 systems (there are no known
      regressions), and they are split up finely to help bisection - but
      there's still a fair bit of residual risk left so caveat emptor"
