[Ben Hutchings]

3.16.42-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Madhavan Srinivasan <maddy@xxxxxxxxxxxxxxxxxx>

commit df21d2fa733035e4d414379960f94b2516b41296 upstream.

Test uses PMC2 to count the event. But PMC1 is being initialized.
Patch to fix it.
