From 75c50f6c8d020d325b180aaefa0c268e0aee7bcd Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Mon, 26 Feb 2018 04:11:21 -0700 Subject: [PATCH] x86/entry/64: Add instruction suffix commit a368d7fd2a3c6babb852fe974018dd97916bcd3b 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.
