[PATCH 0/4] ARM: add support for context tracking subsystem

[Kevin Hilman]

commit 91d1aa43 (context_tracking: New context tracking susbsystem)
generalized parts of the RCU userspace extended quiescent state into
the context tracking subsystem.  Context tracking is then used 
to implement adaptive tickless (a.k.a full nohz)

Mainline currently only includes x86 support for the context tracking
susbsystem and the goal of this series is to add ARM support, in order
to make adaptive tickless functional on ARM.

Depends on the prerequistes series: 
  [PATCH 0/3] ARM: context tracking support prerequisites
  http://marc.info/?l=linux-kernel&m=136382248131438&w=2

Both of which are combined on top of Frederic's 3.9-rc1-nohz1 branch
and available here:
git://git.kernel.org/pub/scm/linux/kernel/git/khilman/linux.git arm-nohz-v2/context-tracking

Using this, I tested adaptive tickless on a 2 CPU ARM SoC (OMAP4
Panda.)

Kevin Hilman (4):
  ARM: context tracking: add exception support
  ARM: context tracking: instrument system calls
  ARM: context tracking: handle post exception/syscall/IRQ work
  ARM: Kconfig: allow context tracking
