Subject: [PATCH 0/5] cputime: Generic virtual based cputime accounting v3

Hi,

Changes since v2 (https://lwn.net/Articles/509575/) are only about
converting the "code domain tracking" naming to "context tracking"
as per Ingo's suggestion. And the result indeed looks much better.

Ring 0 dark knights can pull from:

git://github.com/fweisbec/linux-dynticks.git
	vtime/generic-v3

Warning: this includes dependencies on rcu/idle and vtime
consolidation patchset.

Frederic Weisbecker (5):
  context_tracking: New context 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
