x86/asm: Replace __force_order with a memory clobber (2020-10-01 10:31:48
+0200)
----------------------------------------------------------------
* 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.
