Prepare devfreq core framework to support devices which
can idle. When device idleness is detected perhaps through
runtime-pm, need some mechanism to suspend devfreq load
monitoring and resume back when device is online. Present
code continues monitoring unless device is removed from

In order to save power, it would be useful to schedule work onto non-IDLE cpus
instead of waking up an IDLE one.
To achieve this, we need scheduler to guide kernel frameworks (like: timers
workqueues) on which is the most preferred CPU that must be used for these
tasks.
This routine returns the
Check for current cpu's idleness already done in implementation of
sched_select_cpu() which is called by get_nohz_timer_target(). So, no need to
call idle_cpu() twice, once from sched_select_cpu() and once from timer and
hrtimer before calling get_nohz_timer_target().

Hi All,
This is V2 of my sched_select_cpu() work.

instead of waking up an IDLE one.

workqueues) on which is the most preferred CPU that
Workqueues queues work on current cpu, if the caller haven't passed a preferred
cpu. This may wake up an idle CPU, which is actually not required.
This work can be processed by any CPU and so we must select a non-idle CPU here.
This patch adds in support in workqueue framework to get preferred

That they fail to throw exceptions from new is no reason to disable
set_new_handler, the newhandler is called by the runtime on out of memory

This patchset adds support for AArch64 in all required classes:
- insane
- kernel-arch
- siteinfo
Everything is from public available information (binutils, linux).

This mostly boils down to initialising the Cache Coherent Interconnect
(CCI). We do this by looking in the device-tree for a CCI node, that way
the same semihosting bootwrapper binary can be used on both the
big.LITTLE models and on the A15 models which don't have a CCI.
[PATCH 1/3] bootwrapper:
From: Jon Medhurst t...@linaro.org
The A15xA7 models simulate a Cache Coherent Interconnect (CCI) and this
needs to be initialised correctly for Linux to boot.
To perform this initiation we add the new function configure_from_fdt()
which will look in the fdt for devices to initialise. In this
