Subject: x86, irq: add LOCAL_PERF_VECTOR
X-Git-Tag: v2.6.30-rc1~211^2~26^2~2^2~42
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=193c81b979adbc4a540bf89e75b9039fae75bf82;p=karo-tx-linux.git

x86, irq: add LOCAL_PERF_VECTOR

Add a slot for the performance monitoring interrupt. Not yet used
by any subsystem - but the hardware has it. (This eases integration
with performance monitoring code.)
