Hi,
The changes since v1 (https://lkml.org/lkml/2012/7/27/286) are:
- change naming from "user hooks" to "code domain tracking".
- use of __this_cpu_* APIs instead of __get_cpu_*
There is still a dependency against Paul's rcu/idle branch
and the vtime consolidation set: https://lkml.org/lkml/2012/6/19/216

vtime/generic-v2
Frederic Weisbecker (5):
code_domain: New code domain tracking susbsystem
cputime: Don't allow virtual and irq finegrained cputime accounting
simultaneously
cputime: Allow dynamic switch between tick/virtual based cputime
accounting
cputime: Rename account_system_vtime to account_vtime
cputime: Generic on-demand virtual cputime accounting
