I made some changes to the series: - Handle possible softirq interrupting idle on local_bh_enable() - Have a dedicated vtime.h header file - Do some clearer ifdeffery - Use an irqsafe vtime_account_system() on kvm.
Patches 1/5 and 5/5 are something I really think we want. Patch 3/5 implicitly fixes a bug in s390. If you prefer I can just fix s390 and drop the rest of the patch that is just a micro-optimization in the kvm guest switch path. The rest of the patches is micro optimizations on the irq path. If you think these are pointless over-optimizations, I can just drop these and only keep 1/5, rebase 5/5 and extract the bug fix in s390 that resides in 3/5. Otherwise I'll send a pull request to Ingo in a week or so. If you want to test, it is pullable from: git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git cputime/cleanups-v3 Tested on powerpc and x86. Built tested on ia64. s390 doesn't build defconfig on v3.7-rc2.
