In the x86 32bit PAE CONFIG_TRANSPARENT_HUGEPAGE=y case while holding the
mmap_sem for reading, cmpxchg8b cannot be used to read pmd contents under
Xen.
So instead of dealing only with "consistent" pmdvals in
pmd_none_or_trans_huge_or_clear_bad() (which would be conceptually
simpler) we let pmd_none_or_trans_huge_or_clear_bad() deal with pmdvals
where the low 32bit and high 32bit could be inconsistent (to avoid having
to use cmpxchg8b).
The only guarantee we get from pmd_read_atomic is that if the low part of
the pmd was found null, the high part will be null too (so the pmd will be
considered unstable). And if the low part of the pmd is found "stable"
later, then it means the whole pmd was read atomically (because after a
pmd is stable, neither MADV_DONTNEED nor page faults can alter it anymore,
and we read the high part after the low part).
In the 32bit PAE x86 case, it is enough to read the low part of the pmdval
atomically to declare the pmd as "stable" and that's true for THP and no
THP, furthermore in the THP case we also have a barrier() that will
prevent any inconsistent pmdvals to be cached by a later re-read of the
*pmd.

While upgrading the kernel on a S3C2412 based board I've noted
that it was impossible to boot the board with a 2.6.32 or upper

mapping that is in conflict with the IO mapping definition in
arch/arm/mach-s3c24xx/s3c2412.c.

Commit e813a55eb9c9bc6c8039fb16332cf43402125b30 ("OMAP: board-files:
remove custom PD GPIO handling for DVI output") moved TFP410 chip's
powerdown-gpio handling from the board files to the tfp410 driver. One
gpio_request_one(powerdown-gpio, ...) was mistakenly left unremoved in
the Beagle board file. This causes the tfp410 driver to fail to request
the gpio on Beagle, causing the driver to fail and thus the DVI output
doesn't work.
This patch removes several boot errors from board-omap3beagle.c:
- gpio_request: gpio--22 (DVI reset) status -22
- Unable to get DVI reset GPIO
There is a combination of leftover code and revision confusion.
Additionally, xM support is currently a hack.
For original Beagleboard this removes the double initialization of GPIO
170, properly configures it as an output, and wraps the initialization
in an if block so that xM does not attempt to request it.
For Beagleboard xM it removes reference to GPIO 129 which was part
of rev A1 and A2 designs, but never functioned. It then properly assigns
beagle_dvi_device.reset_gpio in beagle_twl_gpio_setup and removes the
hack of initializing it high. Additionally, it uses
gpio_set_value_cansleep since this GPIO is connected through i2c.
Unfortunately, there is no way to tell the difference between xM A2 and
A3. However, GPIO 129 does not function on rev A1 and A2, and the TWL
GPIO used on A3 and beyond is not used on rev A1 and A2, there are no
problems created by this fix.
Tested on Beagleboard-xM Rev C1 and Beagleboard Rev B4.

Commit 62285963 (usb: musb: drop a gigantic amount of ifdeferry)
got rid of a bunch of ifdefs in the MUSB code. Looks like the
platform init code is still using these dropped defines though,
which in many cases results the board defaulting always to host
mode.
Currently the situation is that USB_MUSB_HDRC is the main
Kconfig option with additional USB_GADGET_MUSB_HDRC so only
these two should be used to select between host and OTG mode.
Fix the situation for omaps. The following users should fix the
platform init code in a similar way:
Dropped Kconfig option Current users

At the moment we call kvmppc_pin_guest_page() in kvmppc_update_vpa()
with two spinlocks held: the vcore lock and the vcpu->vpa_update_lock.
This is not good, since kvmppc_pin_guest_page() calls down_read() and
get_user_pages_fast(), both of which can sleep. This bug was introduced
in 2e25aa5f ("KVM: PPC: Book3S HV: Make virtual processor area
registration more robust").
This arranges to drop those spinlocks before calling
kvmppc_pin_guest_page() and re-take them afterwards. Dropping the
vcore lock in kvmppc_run_core() means we have to set the vcore_state
field to VCORE_RUNNING before we drop the lock, so that other vcpus
won't try to run this vcore.

SCM contains boot addr and boot mode registers to control
other processors on different OMAP versions. It controls the
boot address and mode for DSP based subsystems like: IVA 2.1
(OMAP2430), IVA 2.2 (OMAP3) and DSP (OMAP4).
If contained within SCM registers, when a processor is
booting it uses BOOTADDR to start running the code at that
location. BOOTMOD register specifies a different set of
modes for the processor to execute when booting (from direct,
idle, self-loop, user and default).
Since there was no offset associated with OMAP4, this patch
defines it.

_enable_module is specific to SoCs with PRCM interfaces similar to
that of the OMAP4, so rename it to be consistent with the
corresponding _omap4_disable_module.

AM33XX PRCM module consists of various clockdomains, in all
total we have 18 clockdomains available, with following
controlling options,
- SW Sleep: sw forced sleep transition
- SW Wakeup: sw forced wakeup transition
This patch adds all available clockdomain data, respective
clockdomain operations for AM33XX family of device, and also
integrates it into existing OMAP framework.

Add offset & mask fields to struct powerdomain
In case of AM33xx family of devices, there is no consistency between
PWRSTCTRL & PWRSTST register offsers in PRM space, for example -
PRM_XXX PWRSTCTRL PWRSTST
=======================================
PRM_PER_MOD: 0x0C, 0x08
PRM_WKUP_MOD: 0x04, 0x08
PRM_MPU_MOD: 0x00, 0x04
PRM_DEVICE_MOD: NA, NA
And also, there is no consistency between bit-offsets inside
PWRSTCTRL & PWRSTST register, for example -
PRM_XXX LOGICRET MEMON MEMRET
=======================================
GFX_PWRCTRL: 2, 17, 6
PER_PWRCTRL: 3, 25, 29
MPU_PWRCTRL: 2, 18, 22
WKUP_PWRCTRL: 3, NA, NA
This means, we need to maintain and pass on all this information
in powerdomain handle; so adding fields for,
- PWRSTCTRL/ST register offset
- Logic retention state mask
- mem_on/ret/pwrst/retst mask
Currently, this fields is only applicable and used for AM33XX devices.

As far as PRM/CM/PRCM modules are concerned, AM33XX device is
different than OMAP3 and OMAP4 architectures; so similar to
PRM implementation, handle AM33XX CM separately.
This patch introduces AM33XX CM module low-level api's, used and
required by omap clockdomain and hwmod framework.
Please note that cm-regbits-33xx.h (register bit field offset)
and cm33xx.h (register addr offset) files are mostly auto generated.

This reverts commit d509835e32bd761a2b7b446034a273da568e5573. That commit
breaks support for the generic pass-through mode in the driver for formats,
not natively supported by it. Besides due to a merge conflict it also breaks
driver compilation:
drivers/media/video/mx2_camera.c: In function 'mx2_camera_set_bus_param':
drivers/media/video/mx2_camera.c:937: error: 'pixfmt' undeclared (first use in this function)

Define AM33XX control register, in order to allow access to
control register address space, also add CONTROL_SEC_CLK_CTRL
register offset; both are required in clock tree data,
for wdt0 and timer0 clock source select configuration.

clock input for WDT0 and TIMER0.

Commit a53025724052b2b1edbc982a4a248784638f563d (OMAP: Add debugfs
node to show the summary of all clocks) introduced clock summary,
however, we are interested in seeing snapshot of the clock state, not
in dynamically changing clock configurations as the data provided by
clock summary will then be useless for debugging configuration
issues. So, hold the common lock when dumping the clock summary.

Pull ARM SoC fixes from Olof Johansson:
"A bit larger set than usual, unfortunately -- I've been sitting on
them longer than I meant to so it's really more like 2 -rc pull
requests in one, volume-wise.
Nearly everything is fixes for fallout from the merge window, or other
fixes for bugs. The one exception is the highbank L2-enablement
patch, but it was contained enough that I picked it up anyway:
- i.MX fixes, mostly for clock and pinctrl changes
- OMAP fixes, mostly PM-related
- A patch to enable L2 on highbank

When the ethernet driver was built as a module, it would lock the
machine when loaded. At boot the ethernet clks are unused, so get
turned off. Later, when the module is loaded, the probe function
would access the hardware before the clock was restarted, and the
machine would lock. It has also been determined that when the clk is
turned off, the interface forgets its MAC address, which for most
systems, is set by the boot loader.
When the machine setup file creates a platform device for the
interface, prepare and enable the clock for the interface. This will
ensure it is not turned off. However, if the setup file only
instantiates one platform device, the other will have its clk
disabled, thus maybe saving a little power.
