From 3c598766a2bae1b208470e7cc934ac462561e3cb Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Mon, 11 May 2009 16:49:28 +0100 Subject: x86: fix percpu_{to,from}_op() - the byte operand constraints were wrong for 32-bit - the to-op's input operands weren't properly parenthesized [ Impact: fix possible miscompilation or build failure ] Signed-off-by: Jan Beulich Signed-off-by: H.
