Paul Mackerras d095cd46da perfcounters/powerpc: Make exclude_kernel bit work on Apple G5 processors 
Currently, setting hw_event.exclude_kernel does nothing on the PPC970
variants used in Apple G5 machines, because they have the HV (hypervisor)
bit in the MSR forced to 1, so as far as the PMU is concerned, the
kernel runs in hypervisor mode.  Thus we have to use the MMCR0_FCHV
(freeze counters in hypervisor mode) bit rather than the MMCR0_FCS
(freeze counters in supervisor mode) bit.

This checks the MSR.HV bit at startup, and if it is set, we set the
freeze_counters_kernel variable to MMCR0_FCHV (it was initialized to
MMCR0_FCS).  We then use that whenever we need to exclude kernel events.
