Subject: [PATCH 05/10] perf, tools: Special case uncore_ prefix

From: Andi Kleen <ak@...ux.intel.com>

Special case uncore_ prefix in PMU match, to allow for shorter event
uncore specifications.

Before

perf stat -a -e uncore_cbox/event=0x35,umask=0x1,filter_opc=0x19C/ sleep 1

After

perf stat -a -e cbox/event=0x35,umask=0x1,filter_opc=0x19C/ sleep 1
