This patch fixes an assumption that cclk's initial divisor will always be 1 (or
0 in the register). TSCALE is always initialized on startup with a value of 4
regardless of the inital cclk divisor; so, we can't make the assumption without
making lots of other assumptions. The TPERIOD value is set with a value of the
current cclk (value / (HZ * TSCALE)) - 1; so, we need to adjust based on this
initial frequency and not use cclk's initial divisor for adjusting the tscale.

__skip_sstep() correctly detects the "nontrivial" nop insns,
but since it doesn't update regs->ip we can not really skip
"0x0f 0x1f | 0x0f 0x19 | 0x87 0xc0", the probed application
is killed by SIGILL'ed handle_swbp().
Remove these additional checks. If we want to implement this
correctly we need to know the full insn length to update ->ip.
rep* + nop is fine even without updating ->ip.

Commit 7d7e1eb (ARM: OMAP2+: Prepare for irqs.h removal) and commit ec2c082
(ARM: OMAP2+: Remove hardcoded IRQs and enable SPARSE_IRQ) updated the way
interrupts for OMAP2/3 devices are defined in the HWMOD data structures to
being an index plus a fixed offset (defined by OMAP_INTC_START). The definition
of the PMU interrupts on OMAP2/3 devices is missing the OMAP_INTC_START offset
and so this is causing the allocation of PMU interrupts to fail on OMAP2/3
devices. So add the offset to fix this.
This is patch is based upon Tony's master branch for OMAP.

"This branch contains updates to OMAP and Marvell platforms (kirkwood,
dove, mvebu) that came in after we had done the big multiplatform
merges, so they were kept separate from the rest, and not separated

For OMAP, the updates are:
- Runtime PM conversions for the GPMC and RNG IP blocks
- Preparation patches for the OMAP common clock framework conversion
- clkdev alias additions required by other drivers
- Performance Monitoring Unit (PMU) support for OMAP2, 3, and
non-4430 OMAP4
- OMAP hwmod code and data improvements
- Preparation patches for the IOMMU runtime PM conversion
- Preparation patches for OMAP4 full-chip retention support
For Kirkwood/Dove/mvebu:
- New driver for "address decoder controller" for mvebu, which is a
piece of hardware that configures addressable devices and
peripherals. First user is the boot rom aperture on armada XP
since it is needed for SMP support.
- New device tree bindings for peripherals such as gpio-fan, iconnect
nand, mv_cesa and the above address decoder controller.
- Some defconfig updates, mostly to enable new DT boards and a few
drivers.
- New drivers using the pincontrol subsystem for dove, kirkwood and

git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:
"The first part of the media updates for Kernel 3.7.
This series contain:
- A major tree renaming patch series: now, drivers are organized
internally by their used bus, instead of by V4L2 and/or DVB API,
providing a cleaner driver location for hybrid drivers that
implement both APIs, and allowing to cleanup the Kconfig items and
make them more intuitive for the end user;
- Media Kernel developers are typically very lazy with their duties
of keeping the MAINTAINERS entries for their drivers updated. As
now the tree is more organized, we're doing an effort to add/update
those entries for the drivers that aren't currently orphan;
- Several DVB USB drivers got moved to a new DVB USB v2 core; the new
core fixes several bugs (as the existing one that got bitroted).
Now, suspend/resume finally started to work fine (at least with
some devices - we should expect more work with regards to it);
- added multistream support for DVB-T2, and unified the API for
DVB-S2 and ISDB-S. Backward binary support is preserved;
- as usual, a few new drivers, some V4L2 core improvements and lots
of drivers improvements and fixes.
There are some points to notice on this series:
1) you should expect a trivial merge conflict on your tree, with the
removal of Documentation/feature-removal-schedule.txt: this series
would be adding two additional entries there. I opted to not
rebase it due to this recent change;
2) With regards to the PCTV 520e udev-related breakage, I opted to
fix it in a way that the patches can be backported to 3.5 even
without your firmware fix patch. This way, Greg doesn't need to
rush backporting your patch (as there are still the firmware cache
and firmware path customization issues to be addressed there).
I'll send later a patch (likely after the end of the merge window)
reverting the rest of the DRX-K async firmware request, fully
restoring its original behaviour to allow media drivers to
initialize everything serialized as before for 3.7 and upper.
3) I'm planning to work on this weekend to test the DMABUF patches
for V4L2. The patches are on my queue for several Kernel cycles,
but, up to now, there is/was no way to test the series locally.
I have some concerns about this particular changeset with regards
to security issues, and with regards to the replacement of the old
VIDIOC_OVERLAY ioctl's that is broken on modern systems, due to
GPU drivers change. The Overlay API allows direct PCI2PCI
transfers from a media capture card into the GPU framebuffer, but
its API is crappy. Also, the only existing X11 driver that
implements it requires a XV extension that is not available
anymore on modern drivers. The DMABUF can do the same thing, but
with it is promising to be a properly-designed API. If I can
successfully test this series and be happy with it, I should be
asking you to pull them next week."

The above commit was intentionally made to catch errors like this,
where code relies on the RTC_IRQ definition. The only driver using
it is the legacy PC-style drivers/char/rtc.c driver.
However, the ARM architecture has been using the RTC_LIB framework
since at least 2006, and that doesn't use it.

The PL310_ERRATA_753970 and ARM_ERRATA_764369 symbols only make sense
when the base features for them are enabled, so select them
conditionally in Kconfig to avoid warnings like:
warning: (UX500_SOC_COMMON) selects PL310_ERRATA_753970 which has unmet direct dependencies (CACHE_PL310)
warning: (ARCH_TEGRA_2x_SOC && ARCH_TEGRA_3x_SOC && UX500_SOC_COMMON) selects ARM_ERRATA_764369 which has unmet direct dependencies (CPU_V7 && SMP)

__arch_virt_to_dma expects a virtual address pointer, but
the ks8695 implementation of this macro treats it as an
integer. Adding a type cast avoids hundreds of identical
warning messages.
Without this patch, building acs5k_defconfig results in:

The mityomapl138_cpufreq_init and read_factory_config function in
board-mityomapl138.c are not __init functions and might be called
at a later stage, so da850_register_cpufreq must not be __init either.
Without this patch, building da8xx_omapl_defconfig results in:
WARNING: arch/arm/mach-davinci/built-in.o(.text+0x2eb4): Section mismatch in reference from the function read_factory_config() to the function .init.text:da850_register_cpufreq()
The function read_factory_config() references
the function __init da850_register_cpufreq().
This is often because read_factory_config lacks a __init
annotation or the annotation of da850_register_cpufreq is wrong.

pci_scan_root_bus is __devinit, so iop13xx_scan_bus has to be the

The sys_timer init function is only called at __init time,
so it's safe to mark mv78xx0_timer_init as __init_refok,
which allows us to call orion_time_init without getting
a link time warning.

The *_irq_add function should not be marked __init because the driver

The usb_simtec_init function accesses initdata and should be marked

Pull UAPI disintegration fixes from David Howells:
"There are three main parts:
(1) I found I needed some more fixups in the wake of testing Arm64
(some asm/unistd.h files had weird guards that caused problems -
mostly in arches for which I don't have a compiler) and some
__KERNEL__ splitting needed to take place in Arm64.
(2) I found that c6x was missing some __KERNEL__ guards in its
asm/signal.h. Mark Salter pointed me at a tree with a patch to
remove that file entirely and use the asm-generic variant instead.
(3) Lastly, m68k turned out to have a header installation problem due
to it lacking a kvm_para.h file.
The conditional installation bits for linux/kvm_para.h, linux/kvm.h
and linux/a.out.h weren't very well specified - and didn't work if
an arch didn't have the asm/ version of that file, but there *was*
an asm-generic/ version.
It seems the "ifneq $((wildcard ...),)" for each of those three
headers in include/kernel/Kbuild is invoked twice during header
installation, and the second time it matches on the just installed
asm-generic/kvm_para.h file and thus incorrectly installs
linux/kvm_para.h as well.
Most arches actually have an asm/kvm_para.h, so this wasn't
detectable in those."
* 'uapi-prep' of git://git.infradead.org/users/dhowells/linux-headers:
UAPI: Fix conditional header installation handling (notably kvm_para.h on m68k)
c6x: remove c6x signal.h

Pull ADM Xen support from Konrad Rzeszutek Wilk:
Features:
* Allow a Linux guest to boot as initial domain and as normal guests
on Xen on ARM (specifically ARMv7 with virtualized extensions). PV
console, block and network frontend/backends are working.
Bug-fixes:
* Fix compile linux-next fallout.
* Fix PVHVM bootup crashing.
The Xen-unstable hypervisor (so will be 4.3 in a ~6 months), supports
ARMv7 platforms.
The goal in implementing this architecture is to exploit the hardware
as much as possible. That means use as little as possible of PV
operations (so no PV MMU) - and use existing PV drivers for I/Os
(network, block, console, etc). This is similar to how PVHVM guests
operate in X86 platform nowadays - except that on ARM there is no need
for QEMU. The end result is that we share a lot of the generic Xen
drivers and infrastructure.
Details on how to compile/boot/etc are available at this Wiki:
http://wiki.xen.org/wiki/Xen_ARMv7_with_Virtualization_Extensions
and this blog has links to a technical discussion/presentations on the
overall architecture:

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next
ASoC: Additional updates for v3.7
A couple more updates for 3.7, enhancements to the ux500 and wm2000
drivers, a new driver for DA9055 and the support for regulator bypass
mode. With the exception of the DA9055 this has all had a chance to
soak in -next (the driver was added on Friday so should be in -next
today).

Convert the driver from the outdated omap_pm_set_max_mpu_wakeup_lat
API to the new PM QoS API.
Since the constraint is on the MPU subsystem, use the PM_QOS_CPU_DMA_LATENCY
class of PM QoS. The resulting MPU constraints are used by cpuidle to
decide the next power state of the MPU subsystem.
The I2C device latency timing is derived from the FIFO size and the
clock speed and so is applicable to all OMAP SoCs.

ffa9009c9828db3f74178e459cfbca6e77ff5dd9.
There are problems with how the flag bytes were rearranged, in
particular we really can't move values down into the lowest
16 bits since those are used for individual state bits.
