Clean-up for omap2+ timers from Jon Hunter <jon-hunter@ti.com>:
This series consists mainly of clean-ups for clockevents and
clocksource timers on OMAP2+ devices. The most significant change
in functionality comes from the 5th patch which is changing the
selection of the clocksource timer for OMAP3 and AM335x devices
when gptimers are used for clocksource.
Note that this series depends on 7185684 (ARM: OMAP: use
consistent error checking) in RMK's tree and 960cba6 (ARM:
OMAP5: timer: Update the clocksource name as per clock data)
in omap-for-v3.10/fixes-non-critical. So this branch is based
on a merge of 7185684 and omap-for-v3.10/fixes-non-critical
to avoid non-trivial merge conflicts.

The function tracing control loop used by perf spits out a warning
if the called function is not a control function. This is because
the control function references a per cpu allocated data structure
on struct ftrace_ops that is not allocated for other types of
functions.
commit 0a016409e4 "ftrace: Optimize the function tracer list loop"
Had an optimization done to all function tracing loops to optimize
for a single registered ops. Unfortunately, this allows for a slight
race when tracing starts or ends, where the stub function might be
called after the current registered ops is removed. In this case we
get the following dump:

Check for NULL before calling the following operations from "struct
ieee802154_mlme_ops": assoc_req, assoc_resp, disassoc_req, start_req,
and scan_req.
This fixes a current oops where those functions are called but not
implemented. It also updates the documentation to clarify that they
are now optional by design. If a call to an unimplemented function
is attempted, the kernel returns EOPNOTSUPP via netlink.
The following operations are still required: get_phy, get_pan_id,
get_short_addr, and get_dsn.
Note that the places where this patch changes the initialization
of "ret" should not affect the rest of the code since "ret" was
always set (again) before returning its value.

Some drivers want to tell userspace what uid and gid should be used for
their device nodes, so allow that information to percolate through the
driver core to userspace in order to make this happen. This means that
some systems (i.e. Android and friends) will not need to even run a
udev-like daemon for their device node manager and can just rely in
devtmpfs fully, reducing their footprint even more.

For Nokia RX-51 there is rx51_battery power_supply driver which reporting

We are trying to decompose and decentralize the code in
the DB8500 PRCMU out into subdrivers. The code moved in
this patch concerns a group of functions used for
decoupling and recoupling the IRQs from the GIC. During
sleep and idle the Ux500 system will transfer all IRQ
handling to the PRCMU using these functions.
Basically we are left with the two alternatives of code
placement as:
- arch/arm/mach-ux500/pm.c - this because the code is
closely related to the GIC, and takes ownership of
some of the registers from the PRCMU related to this
PM functionality.
- drivers/mfd/db8500-prcmu-pm.c - because the code is
affecting stuff in the PRCMU register range. But then
this code needs to remap and handle GIC registers.
This patch implementation is taking the first approach.
Currently the cpuidle driver is the only piece of code
using this set of functions, but it will later also be
used by the suspend/resume code which is currently under
review.
The header file is moved to:
<linux/platform_data/arm-ux500-pm.h>
The function prototypes need to be placed in a globally
visible header since the CPUidle code is planned to move
out to drivers/cpuidle.

This patch will make an early remapping of the PRCMU, to be
used when setting up the clocks, that will call down into parts
of the PRCMU driver before it is probed.
Going forward this will be removed like this:
- The mailbox subsystem need to be merged.
http://marc.info/?l=linux-kernel&m=136314559201983&w=2
- At this point the PRCMU clock code can be moved over to the
ux500 clock driver in drivers/clk/ux500/* and maintained
there in a decentralized manner.
- This early initcall and PRCMU base parameters become part of
the ux500_clk_init() call instead.
