4.14-stable review patch. If anyone has any objections, please let me know.
------------------ From: H. Peter Anvin <h...@linux.intel.com> commit 0e2e160033283e20f688d8bad5b89460cc5bfcc4 upstream. i386 and x86-64 uses different registers for arguments; make them available so we don't have to #ifdef in the actual code. Native size and specified size (q, l, w, b) versions are provided. Signed-off-by: H.
