[PATCH] [0/4] PMC-related cleanups [v2]

[Olof Johansson]

The following short series contains a few patches to abstract and clean
up some of the PMC handling on powerpc, followed by the introduction of
the sysfs support for PMCs on PA6T.

Edits since last submit:

* Setting .owner in the sysdev_attr patch
* Using intvec_top instead of intvec_base for setting "soft" vectors
* Fix patch badness with duplicate .pmc_type for one entry


Thanks,

Olof
