Here is the minimal patch that fixes things that do not work and that
can be noticed fairly easily:

        - remove a typo in pfm_check_task_state() which causes
          PFM_READ_PMDS to fail when context is in  PFM_MASKED state.

        - fix a typo in perfmon_mcklinley.h when checking the value
          combinations for when writing to PMC14. This could reject a
          valid request to program PMC14.
