Subject: perf tools: Allow handling a NULL cpu_map as meaning "all cpus"
X-Git-Tag: omap-for-v3.7-rc1/fixes-cpufreq-signed~97^2^2~14
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a14bb7a6fd4a3d563ca971daf462ba4dc294a7a6;p=pandora-kernel.git

perf tools: Allow handling a NULL cpu_map as meaning "all cpus"

Or one with cpu_map->map[0] == -1.

Reducing the boilerplate in setting up an evlist by nor requiring a
cpu_map to be created at all.
