4.14-stable review patch.  If anyone has any objections, please let me know.


From: Jan Beulich <jbeul...@suse.com>

commit 8554004a0231dedf44d4d62147fb3d6a6db489aa upstream.

Omitting suffixes from instructions in AT&T mode is bad practice when
operand size cannot be determined by the assembler from register
operands, and is likely going to be warned about by upstream GAS in the
future (mine does already). Add the single missing suffix here.
