Subject: [PATCH 2/6] perf_counter: powerpc: Use unsigned long for register and constraint values
This changes the powerpc perf_counter back-end to use unsigned long
types for hardware register values and for the value/mask pairs used
in checking whether a given set of events fit within the hardware
constraints. This is in preparation for adding support for the PMU
on some 32-bit powerpc processors. On 32-bit processors the hardware
registers are only 32 bits wide, and the PMU structure is generally
simpler, so 32 bits should be ample for expressing the hardware
constraints. On 64-bit processors, unsigned long is 64 bits wide,
so using unsigned long vs. u64 (unsigned long long) makes no actual
difference.
This makes some other very minor changes: adjusting whitespace to line
things up in initialized structures, and simplifying some code in
hw_perf_disable().
