Ravikiran G Thirumalai f13ef7754f report the per-irq statistics on all arches 
Commit 4004c69ad6 avoids too many remote cpu
references while reporting per-irq stats.  Since we will not have the same
performance penalty of bringing in remote cpu cachelines while reporting
per-irq stats anymore, we can now afford to be consistent and report this
statistic on all arches, all configs.

akpm: affects ia64, alpha and ppc64, mainly.

Kiran earlier said:

Read to /proc/stat takes:
Plain: 	2.622832
With speedup patch: 0.013194
With the per-irq stats commented out: 0.008124

So the performance problems which originally caused those architectures to
disable this statistic should now be fixed up.
