Olof/Arnd,
These patches remove the ARM local timer API. The ARM architected
timers have already moved away from this API so this series
migrates the rest of the users allowing us to remove the API
entirely. Thomas has been kind enough to take the first two
patches into timers/core in the tip tree (thanks Thomas!) so I've
merged that into v3.10-rc1 and then applied the rest of the
patches on top. Let me know if this is acceptable.
These patches have been through multiple rounds and tested by
multiple people since before the 3.10 merge window closed. Only
Barry's ack is missing (Cced).
Since I don't have a tree on kernel.org, David Brown has been
kind enough to push my tag out to his repo. Please pull.
The following changes since commit 42cba6e27c4cddc4df701c597dbfa666e1c013c8:
Merge branch 'timers/core' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip into remove-local-timers (2013-06-24 17:45:02 -0700)

ARM: smp: Remove local timer API (2013-06-24 17:47:34 -0700)
----------------------------------------------------------------
Now that we have a generic arch hook for broadcast we can remove the local
timer API entirely. Doing so will reduce code in ARM core, reduce the
architecture dependencies of our timer drivers, and simplify the code because
we no longer go through an architecture layer that is essentially a hotplug
notifier.

sorry for delayed reply. pls don't wait for my ack. as we are dropping
the marco SoC project this driver supports and moving to a new SoC.
that is why i didn't verify and ack this.
whether this driver is still usable will depend on whether the timer
IP will be re-used in the new chip. so maybe i will delete this driver
once timer IP is decided in the new SoC, or i will repeat to maintain
and verify it if the new SoC uses the same IP.

We need guarantees from Thomas that the branch is stable and will never be
rebased before it hit Linus tree, or we'll be in a world of pain for
dependencies like these.
Thomas, is this branch stable or do you anticipate a rebase?

This branch has merged into Linus' tree. Can this go through the
arm-soc tree now?

Yes, I am still traveling and haven't done any merges for 3.12 yet. This is first in the queue, I should get to it over the weekend or early next week.

Hi,
Merged in as localtimer/removal into next/cleanup.

redo the merge?

Also I think a HAVE_CAN_FLEXCAN if CAN was dragged in to
