f5f9340b98 Add software PMC support. 
New kernel events can be added at various location for sampling or counting.
This will for example allow easy system profiling whatever the processor is
with known tools like pmcstat(8).

Simultaneous usage of software PMC and hardware PMC is possible, for example
looking at the lock acquire failure, page fault while sampling on
instructions.

- Rename pmc.mips to pmc.mips24k since it covers just one CPU,

dceed24a7c Add a flush of the current PMC log buffer before displaying the next top. 
As the underlying block is 4KB if the PMC throughput is low the measurement
will be reported on the next tick. pmcstat(8) use the modified flush API to
reclaim current buffer before displaying next top.
