Subject: [PATCH v2 2/6] perf evlist: Rename cpus to user_requested_cpus
evlist contains cpus and all_cpus. all_cpus is the union of the cpu maps
of all evsels. For non-task targets, cpus is set to be cpus requested
from the command line, defaulting to all online cpus if no cpus are
specified. For an uncore event, all_cpus may be just CPU 0 or every online
CPU. This causes all_cpus to have fewer values than the cpus variable
which is confusing given the 'all' in the name. To try to make the behavior
clearer, rename cpus to user_requested_cpus and add comments on the two
struct variables.
