59abbd1e7c sparc64: Initial hw perf counter support. 
Only supports one simple counter and only UltraSPARC-IIIi chips.

5686f9c3d6 sparc64: Implement a real set_perf_counter_pending(). 
When the perf counter subsystem needs to reschedule work out
from an NMI, it invokes set_perf_counter_pending().

This triggers a non-NMI irq which should invoke
perf_counter_do_pending().

Currently this won't trigger because sparc64 won't trigger
the perf counter subsystem from NMIs, but when the HW counter
support is added it will.

This wires up the perf_counter_open() syscall so that basic
software support for perf is working.
