The members of Atmel's at91sam9x5 family (9x5) have a broken RTC
interrupt mask register (AT91_RTC_IMR). It does not reflect enabled
interrupts but instead always returns zero.
The kernel's rtc-at91rm9200 driver handles the RTC for the 9x5 family.
Currently when the date/time is set, an interrupt is generated and this
driver neglects to handle the interrupt. The kernel complains about the
un-handled interrupt and disables it henceforth. This not only breaks
the RTC function, but since that interrupt is shared (Atmel's SYS
interrupt) then other things break as well (e.g. the debug port no
longer accepts characters).
Tested on the at91sam9g25. Bug confirmed by Atmel.
This patch (of 5):
Add missing match-table compile guard.

When booted in legacy mode device_init_wakeup() gets called by
drivers/mfd/twl-core.c when the children are initialized. However, when
booted using device tree, the children are created with
of_platform_populate() instead add_children().
This means that the RTC driver will not have device_init_wakeup() set,
and we need to call it from the driver probe like RTC drivers typically
do.
Without this we cannot test PM wake-up events on omaps for cases where
there may not be any physical wake-up event.

This mutex usage was added into the ioctl path when the big kernel lock

(or can easily be made so) and we don't want ioctl() to be single

During resume, we call hpet_rtc_timer_init after masking an irq bit in
hpet. This will cause the call to hpet_disable_rtc_channel to be undone
if RTC_AIE is the only bit not masked.
Allowing the cmos interrupt handler to run before resuming caused some
issues where the timer for the alarm was not removed. This would cause
other, later timers to not be cleared, so utilities such as hwclock
would time out when waiting for the update interrupt.

Commit 10a7a07713 ("xen: tmem: enable Xen

be able to asynchronously to call tmem_frontswap_init before
or after the swap image had been set. That was added in git
commit 905cd0e1bf
("mm: frontswap: lazy initialization to allow tmem backends to build/run as modules").
Which means we could do this (The common case):
modprobe tmem [so calls frontswap_register_ops, no ->init]
modifies tmem_frontswap_poolid = -1
swapon /dev/xvda1 [__frontswap_init, calls -> init, tmem_frontswap_poolid is
< 0 so tmem hypercall done]
Or the failing one:
swapon /dev/xvda1 [calls __frontswap_init, sets the need_init bitmap]
modprobe tmem [calls frontswap_register_ops, -->init calls, finds out
tmem_frontswap_poolid is 0, does not make a hypercall.
Later in the module_init, sets tmem_frontswap_poolid=-1]
Which meant that in the failing case we would not call the hypercall
to initialize the pool and never be able to make any frontswap
backend calls.
Moving the frontswap_register_ops after setting the tmem_frontswap_poolid
fixes it.

From Shawn Guo, mxs fixes for 3.10:
- Since the time we move to MULTI_IRQ_HANDLER, the 0x7f polling for no
interrupt in icoll_handle_irq() becomes insane, because 0x7f is an
valid interrupt number, the irq of gpio bank 0. That unnecessary
polling results in the driver not detecting when irq 0x7f is active
which makes the machine effectively dead lock. The fix removes the
interrupt poll loop and allows usage of gpio0 interrupt without an
infinite loop.

With the introduction of ACPI scan handlers, an ACPI device object
with an ACPI scan handler attached to it must not be bound to an ACPI
driver any more. Therefore it doesn't make sense to match those
ACPI device objects against a newly registered ACPI driver in
acpi_bus_match(), so make that function return 0 if the device
object passed to it has an ACPI scan handler attached.
This also addresses a regression related to a broken ACPI table in
the BIOS, where it has defined a _ROM method under the PCI root
bridge object. This causes the video module to treat that object
as a display controller device (since only display devices are
supposed to have a _ROM method defined according to the ACPI spec).
As a result, the ACPI video driver binds to the PCI root bridge
object and overwrites the previously assigned driver_data field of
it, causing subsequent calls to acpi_get_pci_dev() to fail.

Commit 4b31e774 (Always set P-state on initialization) fixed bug
#4634 and caused the driver to always set the target P-State at
least once since the initial P-State may not be the desired one.
Commit 5a1c0228 (cpufreq: Avoid calling cpufreq driver's target()
routine if target_freq == policy->cur) caused a regression in
this behavior.
This fixes the regression by setting policy->cur based on the CPU's
target frequency rather than the CPU's current reported frequency
(which may be different). This means that the P-State will be set
initially if the CPU's target frequency is different from the
governor's target frequency.
This fixes an issue where setting the default governor to
performance wouldn't correctly enable turbo mode on all cores.

The sahara crypto driver has an incorrect MODULE_DEVICE_TABLE, which
prevents us from actually building this driver as a loadable module.
sahara_dt_ids is a of_device_id array, so we have to use
MODULE_DEVICE_TABLE(of, ...).

Three regression fixes and one no-lvds quirk update. The regression Egbert

Regression from merging the old nv50/nvd9 code together, and may be
needed to fully fix fdo#64904.
The value is ignored completely by the hardware starting from nva3.

Code refactoring in commit 8e9e3d2dea
(drm/nv84/disp: move hdmi control into core) disabled HDMI audio on my
nv84 by removing too much old code without adding it in the new one.
This patch adds the missing code within the new code layout resulting in
HDMI audio working again.
It should work on any HDMI head, but due to lacking ahrdware I could
only test the (1st) one.
It also might be possible that similar code is needed for nva3, which I
can't test.
