Subject[PATCH] perf tools: Allow multiple cpus record for -p option
Date
Currently we don't create default CPU map for task related
target, like:

$ perf record -p <pid>

This makes record command to disable inherited events.
which is not desired behaviour (we have special option
for that (-i) anyway).

Fixing this by creating default CPU map for task related
processes.
