Merge tag 'cpuinit-v4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux
Pull __cpuinit removal from Paul Gortmaker:
"Remove __cpuinit macros and users.
We removed the __cpuinit stuff in 3.11-rc1 with commit 22f0a27367
("init.h: remove __cpuinit sections from the kernel") but we left some
no-op stubs as a courtesy to unmerged code.
Here we get rid of the stubs as well, since (as can be seen in these
changes) they are enabling use cases to sneak back in, primarily from
older BSP code that has been living out of tree for some time prior to
getting mainlined. So we get rid of these "new" users 1st and then
get rid of the stubs.
Obviously, getting rid of the stubs can't happen until all the users
are gone, so I had to keep this together as a series, even though some
of these commits since got picked up into maintainers trees as well.
The nature of this change is such that it should have zero impact on
the generated runtime.
This is one of several independent cleanup branches aimed at enabling
better organization in the init.h and module.h code. They have been
getting coverage in the linux-next tree for the last month, in
addition to my local testing, which also covers approximately a half
dozen or more architectures"

All ARMv5 and older CPUs invalidate their caches in the early assembly
setup function, prior to enabling the MMU. This is because the L1
cache should not contain any data relevant to the execution of the
kernel at this point; all data should have been flushed out to memory.
This requirement should also be true for ARMv6 and ARMv7 CPUs - indeed,
these typically do not search their caches when caching is disabled (as
it needs to be when the MMU is disabled) so this change should be safe.
ARMv7 allows there to be CPUs which search their caches while caching is
disabled, and it's permitted that the cache is uninitialised at boot;
for these, the architecture reference manual requires that an
implementation specific code sequence is used immediately after reset
to ensure that the cache is placed into a sane state. Such
functionality is definitely outside the remit of the Linux kernel, and
must be done by the SoC's firmware before _any_ CPU gets to the Linux
kernel.
Changing the data cache clean+invalidate to a mere invalidate allows us
to get rid of a lot of platform specific hacks around this issue for
their secondary CPU bringup paths - some of which were buggy.

While it should be the responsibility of the bootloader to do this,
and there exists a fix in a community u-boot, all u-boot based systems

Therefore to not require every developer to update their u-boot, add a

Sometimes the debug module may not work well after resume, since it has

Reset dapswjdp is controlled by JTAG_TRSTN, if the iomux of this pin is

- Removal of CSR's "Marco" SoC platform that never made it out to the

- Common code changes for Nvidia Tegra132 (64-bit SoC)
We're seeing more and more platforms having a harder time labelling

The rk3288 board uses the architected timers and these ones are shutdown when
the cpu is powered down. There is a need of a broadcast timer in this case to
ensure proper wakeup when the cpus are in sleep mode and a timer expires.
This driver provides the basic timer functionnality as a backup for the local
timers at sleep time.
The timer belongs to the alive subsystem. It includes two programmables 64 bits
timer channels but the driver only uses 32bits. It works with two operations
mode: free running and user defined count.
Programing sequence:
1. Timer initialization:
* Disable the timer by writing '0' to the CONTROLREG register
* Program the timer mode by writing the mode to the CONTROLREG register
* Set the interrupt mask
2. Setting the count value:
* Load the count value to the registers COUNT0 and COUNT1 (not used).
3. Enable the timer
* Write '1' to the CONTROLREG register with the mode (free running or user)

rk3288 SoCs have a function to automatically switch between jtag/sdmmc pinmux
settings depending on the card state. This collides with a lot of assumptions.
It only works when using the internal card-detect mechanism and breaks
horribly when using either the normal card-detect via the slot-gpio function
or via any other pin. Also there is of course no link between the mmc and jtag
on the software-side, so the jtag clocks may very well be disabled when the
card is ejected and the soc switches back to the jtag pinmux.
Leaving the switching function enabled did result in mmc timeouts and rcu
stalls thus hanging the system on 3.19-rc1. Therefore disable it in all cases,
as we expect the devicetree to explicitly select either mmc or jtag pinmuxes
anyway.

Only cortex-A9 need invalid L1, A7/A12/A15/A17 should not invalid L1, since
for A7/A12/A15, the invalidation would be taken as clean and invalidate.
If you use the software manual invalidation instead of hardware invalidation
(assert l1/l2rstdisable during reset) after reset, there is tiny change that
some cachelines would be in dirty and valid state after reset(since the ram
content would be random value after reset), then the unexpected clean might
lead to system crash.
It is a known issue for the A12/A17 MPCore multiprocessor that the active
processors might be stalled when the individual processor is powered down,
we can avoid this prolbem by softreset the processor before power it down.

The pmu register space is - like the GRF - shared by quite some peripherals.
On the rk3188 and rk3288 even parts of the pinctrl are living there.
Therefore we normally shouldn't map it a second time when the syscon
does this already.
Therefore convert the cpu power-domain handling to access the pmu via a
regmap and at first try to get it via the syscon interface.
Getting this syscon will only fail if the pmu node does not have the
"syscon" compatible and thus does not get shared with other drivers.
In this case we map it like before and create the necessary regmap on
top of it.

Unlike the board branch, this keeps having large sets of changes for
every release, but that's quite expected and is so far working well.
Most of this is plumbing for various device bindings and new platforms,
but there's also a bit of cleanup and code removal for things that
are moved from platform code to DT contents (some OMAP clock code in
particular).
There's also a pinctrl driver for tegra here (appropriately acked),
that's introduced this way to make it more bisectable.
I'm happy to say that there were no conflicts at all with this branch
this release, which means that changes are flowing through our tree as
expected instead of merged through driver maintainers (or at least not
done with conflicts).
There are several new boards added, and a couple of SoCs. In no particular
order:
* Rockchip RK3288 SoC support, including DTS for a dev board that they
have seeded with some community developers.
* Better support for Hardkernel Exynos4-based ODROID boards.
* CCF conversions (and dtsi contents) for several Renesas platforms.
* Gumstix Pepper (TI AM335x) board support
* TI eval board support for AM437x
* Allwinner A23 SoC, very similar to existing ones which mostly has
resulted in DT changes for support. Also includes support for an Ippo
tablet with the chipset.
* Allwinner A31 Hummingbird board support, not to be confused with the
SolidRun i.MX-based Hummingboard.
* Tegra30 Apalis board support

Pull ARM SoC device-tree changes from Olof Johansson:
"Unlike the board branch, this keeps having large sets of changes for
every release, but that's quite expected and is so far working well.
Most of this is plumbing for various device bindings and new
platforms, but there's also a bit of cleanup and code removal for
things that are moved from platform code to DT contents (some OMAP
clock code in particular).
There's also a pinctrl driver for tegra here (appropriately acked),
that's introduced this way to make it more bisectable.

Pull ARM updates from Russell King:
- Major clean-up of the L2 cache support code. The existing mess was
becoming rather unmaintainable through all the additions that others
have done over time. This turns it into a much nicer structure, and
implements a few performance improvements as well.
- Clean up some of the CP15 control register tweaks for alignment
support, moving some code and data into alignment.c
- DMA properties for ARM, from Santosh and reviewed by DT people. This
adds DT properties to specify bus translations we can't discover
automatically, and to indicate whether devices are coherent.
- Hibernation support for ARM
- Make ftrace work with read-only text in modules
- add suspend support for PJ4B CPUs
- rework interrupt masking for undefined instruction handling, which
allows us to enable interrupts earlier in the handling of these
exceptions.
- support for big endian page tables
- fix stacktrace support to exclude stacktrace functions from the
trace, and add save_stack_trace_regs() implementation so that kprobes
can record stack traces.
- Add support for the Cortex-A17 CPU.
- Remove last vestiges of ARM710 support.
- Removal of ARM "meminfo" structure, finally converting us solely to
memblock to handle the early memory initialisation.

Board-related updates. This branch is getting smaller and smaller, which is
the whole idea so that's reassuring.
Right now by far most of the code is related to shmobile updates, and
they are now switching over to removal of board code and migration to
multiplatform, so we'll see their board code base shrink in the near
future too, I hope.
In addition to that is some defconfig updates, some display updates for OMAP
