Commit-ID: b1cccb1bb01dc1cb89f58723a58c3d4988d44d94 Gitweb: http://git.kernel.org/tip/b1cccb1bb01dc1cb89f58723a58c3d4988d44d94 Author: Jan Beulich <JBeulich@xxxxxxxxxx> AuthorDate: Thu, 2 Sep 2010 13:55:11 +0100 Committer: Ingo Molnar <mingo@xxxxxxx> CommitDate: Fri, 3 Sep 2010 08:14:10 +0200 x86-64: Use symbolics instead of raw numbers in entry_64.S ... making the code a little less fragile. Also use pushq_cfi instead of raw CFI annotations in two more places, and add two missing annotations after stack pointer adjustments which got modified here anyway.
