History
Ryan Stone 04001891bb When configuring a system-wide couting PMC, hwpmc was incorrectly logging process mappings for that PMC. Nothing ever reads pmc logs out of a counting PMC, so the log buffers were leaked when the PMC was deconfigured. The process mappings are only useful for sampling PMCs anyway, so only log the mappings if the PMC is a sampling PMC. 
This bug would cause allocating sample-mode PMCs to fail with ENOMEM after allocating several counting-mode PMCs.
