This is rather too late so it'd be completely understandable if you
don't want to pull it at this point, I had thought I'd sent this earlier
but it seems I didn't. Everything has been in -next for some time now.
The main set of fixes here are mopping up some more issues with MMIO,
fixing handling of endianness configuration in DT (which just wasn't
working at all) and cases where the register and value endianness are
different.
There is also a fix for bulk register reads on SPMI.

Allowing unprivileged kernel profiling lets any user dump follow kernel
control flow and dump kernel registers. This most likely allows trivial
kASLR bypassing, and it may allow other mischief as well. (Off the top
of my head, the PERF_SAMPLE_REGS_INTR output during /dev/urandom reads
could be quite interesting.)

It appears people are reading this document as a requirements list for
building hardware. This is not the intent of this document. Nor is it
particularly suited for this purpose.
The primary purpose of this document is our collective attempt to define
a set of primitives that (hopefully) allow us to write correct code on
the myriad of SMP platforms Linux supports.
Its a definite work in progress as our understanding of these platforms,
and memory ordering in general, progresses.
Nor does being mentioned in this document mean we think its a
particularly good idea; the data dependency barrier required by Alpha
being a prime example. Yes we have it, no you're insane to require it
when building new hardware.

The default remains 127, which is good for most cases, and not even hit
most of the time, but then for some cases, as reported by Brendan, 1024+
deep frames are appearing on the radar for things like groovy, ruby.
And in some workloads putting a _lower_ cap on this may make sense. One
that is per event still needs to be put in place tho.
The new file is:
# cat /proc/sys/kernel/perf_event_max_stack
127
Chaging it:
# echo 256 > /proc/sys/kernel/perf_event_max_stack
# cat /proc/sys/kernel/perf_event_max_stack
256
But as soon as there is some event using callchains we get:
# echo 512 > /proc/sys/kernel/perf_event_max_stack
-bash: echo: write error: Device or resource busy
#
Because we only allocate the callchain percpu data structures when there
is a user, which allows for changing the max easily, its just a matter
of having no callchain users at that point.

recent regressions. Changes are across several platforms, so
I'm listing every change separately here.
Regressions since 4.5:
- A correction of the psci firmware DT binding, to prevent
users from relying on unintended semantics
- Actually getting the newly merged clock driver for some OMAP
platforms to work
- A revert of patches for the Qualcomm BAM, these need to be
reworked for 4.7 to avoid breaking boards other than the one
they were intended for
- A correction for the I2C device nodes on the Socionext Uniphier
platform
- i.MX SDHCI was broken for non-DT platforms due to a change
with the setting of the DMA mask
- A revert of a patch that accidentally added a nonexisting
clock on the Rensas "Porter" board
- A couple of OMAP fixes that are all related to suspend after
the power domain changes for dra7
- On Mediatek, revert part of the power domain initialization
changes that broke mt8173-evb
Fixes for older bugs:
- Workaround for an "external abort" in the omap34xx
suspend/resume code.
- The USB1/eSATA should not be listed as an excon device on
am57xx-beagle-x15 (broken since v4.0)
- A v4.5 regression in the TI AM33xx and AM43XX DT specifying
incorrect DMA request lines for the GPMC
- The jiffies calibration on Renesas platforms was incorrect
for some modern CPU cores.
- A hardware errata woraround for clockdomains on TI DRA7

Pull ARM SoC fixes from Arnd Bergmann:
"Here are the latest bug fixes for ARM SoCs, mostly addressing recent
regressions. Changes are across several platforms, so I'm listing
every change separately here.
Regressions since 4.5:
- A correction of the psci firmware DT binding, to prevent users from
relying on unintended semantics
- Actually getting the newly merged clock driver for some OMAP
platforms to work
- A revert of patches for the Qualcomm BAM, these need to be reworked
for 4.7 to avoid breaking boards other than the one they were
intended for
- A correction for the I2C device nodes on the Socionext Uniphier
platform
- i.MX SDHCI was broken for non-DT platforms due to a change with the
setting of the DMA mask
- A revert of a patch that accidentally added a nonexisting clock on
the Rensas "Porter" board
- A couple of OMAP fixes that are all related to suspend after the
power domain changes for dra7
- On Mediatek, revert part of the power domain initialization changes
that broke mt8173-evb
Fixes for older bugs:
- Workaround for an "external abort" in the omap34xx suspend/resume
code.
- The USB1/eSATA should not be listed as an excon device on
am57xx-beagle-x15 (broken since v4.0)
- A v4.5 regression in the TI AM33xx and AM43XX DT specifying
incorrect DMA request lines for the GPMC
- The jiffies calibration on Renesas platforms was incorrect for some
modern CPU cores.
- A hardware errata woraround for clockdomains on TI DRA7"

Currently ARM CPUs DT bindings allows different enable-method value for
PSCI based systems. On ARM 64-bit this property is required and must be
"psci" while on ARM 32-bit systems this property is optional and must
be "arm,psci" if present.
However, "arm,psci" has always been the compatible string for the PSCI
node, and was never intended to be the enable-method. So this is a bug
in the binding and not a deliberate attempt at specifying 32-bit
differently.
This is problematic if 32-bit OS is run on 64-bit system which has
"psci" as enable-method rather than the expected "arm,psci".
So let's unify the value into "psci" and remove support for "arm,psci"
before it finds any users.

The CPU load update related functions have a weak naming convention
currently, starting with update_cpu_load_*() which isn't ideal as
"update" is a very generic concept.
Since two of these functions are public already (and a third is to come)
that's enough to introduce a more conventional naming scheme. So let's
do the following rename instead:
update_cpu_load_*() -> cpu_load_update_*()

It seems suspend worked earlier as things were only partially initialized,
while now we initialize things properly for dra7.
Note that the "ARM: OMAP: Catch callers of revision information prior
to it being populated" had to be reverted as it caused bogus warnings
for other SoCs because omap initcalls bail out based on revision being
set to 0 for other SoCs. These initcalls will mostly just disappear
when we drop support for omap3 legacy booting.
Also included is a fix for dra7 sys_32k_ck clock source that is not
enabled on boot making system fall back to using emulated clock.
