powerpc/perf: Move perf core & PMU code into a subdirectory The perf code has grown a lot since it started, and is big enough to warrant its own subdirectory. For reference it's ~60% bigger than the oprofile code. It declutters the kernel directory, makes it simpler to grep for "just perf stuff", and allows us to shorten some filenames. While we're at it, make it more obvious that we have two implementations of the core perf logic. One for (roughly) Book3S CPUs, which was the original implementation, and the other for Freescale embedded CPUs.

powerpc/perf: Add support for sampling interrupt register state The perf infrastructure uses a bit mask to find out valid registers to display. Define a register mask for supported registers defined in uapi/asm/perf_regs.h. The bit positions also correspond to register IDs which is used by perf infrastructure to fetch the register values. CONFIG_HAVE_PERF_REGS enables sampling of the interrupted machine state.

powerpc/perf: Add basic assembly code to read BHRB entries on POWER8 This patch adds the basic assembly code to read BHRB buffer. BHRB entries are valid only after a PMU interrupt has happened (when MMCR0[PMAO]=1) and BHRB has been freezed. BHRB read should not be attempted when it is still enabled (MMCR0[PMAE]=1) and getting updated, as this can produce non-deterministic results.

powerpc/perf: Add e6500 PMU driver e6500 core performance monitors has the following features: - 6 performance monitor counters - 512 events supported - no threshold events e6500 PMU has more specific events (Data L1 cache misses, Instruction L1 cache misses, etc ) than e500 PMU (which only had Data L1 cache reloads, etc). Where available, the more specific events have been used which will produce slightly different results than e500 PMU equivalents.
