[RFC PATCH] kick sleeping idle CPUS on cpu_idle_wait

2008-01-07 Thread Steven Rostedt
Sometimes cpu_idle_wait gets stuck because it might miss CPUS that are already in idle, have no tasks waiting to run and have no interrupts going to them. This is common on bootup when switching cpu idle governors. This patch accounts for CPUs already in idle. Background: --- I notice t

[PATCH 00/10] percpu: Per cpu code simplification V3

This patchset simplifies the code that arches need to maintain to support per cpu functionality. Most of the code is moved into arch independent code. Only a minimal set of definitions is kept for each arch. The patch also unifies the x86 arch so that there is only a single asm-x86/percpu.h V1->
