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

From: Kevin Hilman
Date: Wed Mar 20 2013 - 20:10:19 EST

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

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

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
