From 07bd8516a2f967aa67904c68ab97bb896a448b09 Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Fri, 22 Oct 2010 08:22:35 +0100 Subject: [PATCH] x86, asm: Restore parentheses around one pushl_cfi argument These were (intentionally) stripped by "fix CFI macro invocations to deal with shortcomings in gas" to expose problems with unexpected splitting of arguments by older gas also on newer versions, but as it turns out there is at least one distro (Ubuntu 6.06) where even not having *any* spaces in a macro argument doesn't reliably prevent splitting into multiple arguments.
