Linus Torvalds 029f56db6a * Use XORL instead of XORQ to avoid a REX prefix and save some bytes in 
the .fixup section, by Uros Bizjak.
 
 * Replace __force_order dummy variable with a memory clobber to fix LLVM
 requiring a definition for former and to prevent memory accesses from
 still being cached/reordered, by Arvind Sankar.
