powerpc: Create PPC_WARN_ALIGNMENT to match PPC_WARN_EMULATED

2009-10-28T05:13:03Z

perf_event wants a separate event for alignment and emulation faults, so create another emulation event. This will make it easy to hook in perf_event at one spot. We pass in regs which will be required for these events. Signed-off-by: Anton Blanchard Signed-off-by: Paul Mackerras

powerpc: Keep track of emulated instructions

2009-05-21T05:44:26Z

If CONFIG_PPC_EMULATED_STATS is enabled, make available counters for the various classes of emulated instructions under /sys/kernel/debug/powerpc/emulated_instructions/ (assumed debugfs is mounted on /sys/kernel/debug). Optionally (controlled by /sys/kernel/debug/powerpc/emulated_instructions/do_warn), rate-limited warnings can be printed to the console when instructions are emulated.
