Subject: [PATCH 3.13 044/149] perf trace: Decode architecture-specific signal numbers

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

------------------

From: Ben Hutchings <ben@...adent.org.uk>

commit 02c5bb4a352a4cca56e9b5d3a2a57d61062eb2e1 upstream.

SIGSTKFLT is not defined on alpha, mips or sparc.

SIGEMT and SIGSWI are defined on some architectures and should be
decoded here if so.
