Subject: sparc64: Implement a real set_perf_counter_pending().
X-Git-Tag: v2.6.32-rc1~702^2~6
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5686f9c3d67d5a20108fa26105c98b042df13123;p=pandora-kernel.git

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.
