Paul Mackerras 98fb1807b9 perf_counter: powerpc: Make powerpc perf_counter code safe for 32-bit kernels
This abstracts a few things in arch/powerpc/kernel/perf_counter.c
that are specific to 64-bit kernels, and provides definitions for
32-bit kernels.  In particular,

* Only 64-bit has MMCRA and the bits in it that give information
  about a PMU interrupt (sampled PR, HV, slot number etc.)
* Only 64-bit has the lppaca and the lppaca->pmcregs_in_use field
* Use of SDAR is confined to 64-bit for now
* Only 64-bit has soft/lazy interrupt disable and therefore
  pseudo-NMIs (interrupts that occur while interrupts are soft-disabled)
* Only 64-bit has PMC7 and PMC8
* Only 64-bit has the MSR_HV bit.

This also fixes the types used in a couple of places, where we were
using long types for things that need to be 64-bit.
