Subject: [RFC PATCH 0/5] cputime: Generic virtual based cputime accounting v2

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

Bold warriors can pull from:

	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
