sched/x86: Remove broken power estimation

The x86 sched power implementation has been broken forever and gets in the way of other stuff, remove it. [ For archaeological interest, fixing this code would require dealing with the cross-cpu calling of these functions and more importantly, we need to filter idle time out of the a/m-perf stuff because the ratio will go down to 0 when idle, giving a 0 capacity which is not what we'd want. ] Signed-off-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Arjan van de Ven <arjan@linux.intel.com> Link: http://lkml.kernel.org/r/1339594110.8980.38.camel@twins Signed-off-by: Ingo Molnar <mingo@kernel.org>
