[PATCH 0/5] cputime: Moar cleanups / enhancements v2

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
