Pull ARM fixes from Russell King:
"Nothing too disasterous, the biggest thing being the removal of the
regulator support for vcore in the AMBA driver; only one SoC was using
this and it got broken during the last merge window, which then
started causing problems for other people. Mutual agreement was
reached for it to be removed."

Commit 26f41062f28d ("PCI: check for pci bar restore completion and
retry") attempted to address problems with PCI BAR restoration on
systems where FLR had not been completed before pci_restore_state() was
called, but it did that in an utterly wrong way.
First off, instead of retrying the writes for the BAR registers only, it
did that for all of the PCI config space of the device, including the
status register (whose value after the write quite obviously need not be
the same as the written one). Second, it added arbitrary delay to
pci_restore_state() even for systems where the PCI config space
restoration was successful at first attempt. Finally, the mdelay(10) it
added to every iteration of the writing loop was way too much of a delay
for any reasonable device.
All of this actually caused resume failures for some devices on Mikko's
system.
To fix the regression, make pci_restore_state() only retry the writes
for BAR registers and only wait if the first read from the register
doesn't return the written value. Additionaly, make it wait for 1 ms,
instead of 10 ms, after every failing attempt to write into config
space.

Commit 18a4d0a22ed6 ("[SCSI] Handle disk devices which can not process

Ensure that a driver is registered and make the driver accessor function

The OMAP driver needs a 'depends on ARCH_OMAP2PLUS' since it only
builds for OMAP2+ platforms.
This 'depends on' was in the original patch from Russell King, but was
erroneously removed by me when making this option user-selectable in
commit b09db45c (cpufreq: OMAP driver depends CPUfreq tables.) This
patch remedies that.
Apologies to Russell King for breaking his originally working patch.
Also, thanks to Grazvydas Ignotas for reporting the same problem.

Add a CONFIG option to allow the output from Magic SysRq to be output
immediately, even if this causes large latencies.
If PREEMPT_RT_FULL, printk() will not try to acquire the console lock
when interrupts or preemption are disabled. If the console lock is
not acquired the printk() output will be buffered, but will not be
output immediately. Some drivers call into the Magic SysRq code
with interrupts or preemption disabled, so the output of Magic SysRq
will be buffered instead of printing immediately if this option is
not selected.
Even with this option selected, Magic SysRq output will be delayed
if the attempt to acquire the console lock fails.

To work around this in the short term you can use this patch, in
addition to the clocksource watchdog patch that Thomas brewed up.
Comments are welcome of course. Ultimately the right solution is to
change separation between the console and the HW to have a polled mode
+ work queue so as not to introduce any kind of latency.

__raid_run_ops() disables preemption with get_cpu() around the access

Argh, cut and paste wasn't enough...
Use this patch instead. It needs an irq disable. But, believe it or not,
on SMP this is actually better. If the irq is shared (as it is in Mark's
case), we don't stop the irq of other devices from being handled on
another CPU (unfortunately for Mark, he pinned all interrupts to one CPU).

Preempt-RT runs into a live lock issue with the NETDEV_TX_LOCKED micro

There is no real reason to use a rwlock for devtree_lock. It even
could be a mutex, but unfortunately it's locked from cpu hotplug
pathes which can't schedule :(
So it needs to become a raw lock on rt as well. devtree_lock would be
the only user of a raw_rw_lock, so we are better of cleaning the
recursive locking pathes which allows us to convert devtree_lock to a
read_lock.

Neither the phy interrupt nor the timer callback which updates the
link status in absense of a phy interrupt are taking lp->lock which
serializes the MDIO access. This works on mainline as at91 is an UP
machine. On preempt-rt the timer callback can run even in the
spin_lock_irq(&lp->lock) protected code pathes because spin_lock_irq
is neither disabling interrupts nor disabling preemption.
Fix this by adding proper locking to at91ether_phy_interrupt() and
at91_check_ether() which serializes the access on -rt.

The underlying hardware is edge triggered but presented by XICS as level
triggered. The edge triggered interrupts are not reissued after masking. This
is not a problem in mainline which does not mask the interrupt (relying on the
EOI mechanism instead). The threaded interrupts in PREEMPT_RT do mask the
interrupt, and can lose interrupts that occurred while masked, resulting in a
hung ethernet interface.
The receive handler simply calls napi_schedule(), as such, there is no
significant additional overhead in making this non-threaded, since we either
wakeup the threaded irq handler to call napi_schedule(), or just call
napi_schedule() directly to wakeup the softirqs. As the receive handler is
lockless, there is no need to convert any of the ehea spinlock_t's to
raw_spinlock_t's.
Without this patch, a simple scp file copy loop would fail quickly (usually
seconds). We have over two hours of sustained scp activity with the patch
applied.
Credit goes to Will Schmidt for lots of instrumentation and tracing which
clarified the scenario and to Thomas Gleixner for the incredibly simple
solution.

The AMBA bus regulator support is being used to model on/off switches
for power domains which isn't terribly idiomatic for modern kernels with
the generic power domain code and creates integration problems on platforms
which don't use regulators for their power domains as it's hard to tell
the difference between a regulator that is needed but failed to be provided
and one that isn't supposed to be there (though DT does make that easier).
Platforms that wish to use the regulator API to manage their power domains
can indirect via the power domain interface.
This feature is only used with the vape supply of the db8500 PRCMU
driver which supplies the UARTs and MMC controllers, none of which have
support for managing vcore at runtime in mainline (only pl022 SPI
controller does). Update that supply to have an always_on constraint
until the power domain support for the system is updated so that it is
enabled for these users, this is likely to have no impact on practical
systems as probably at least one of these devices will be active and
cause AMBA to hold the supply on anyway.

Pull tty and serial fixes from Greg KH:
"Here are some tty and serial fixes for 3.4-rc2.
Most important here is the pl011 fix, which has been reported by about
100 different people, which means more people use it than I expected
:)
There are also some 8250 driver reverts due to some problems reported
by them. And other minor fixes as well.

Pull staging tree fixes from Greg KH:
"Here are a number of bugfixes for the drivers/staging/ portion of the
kernel that have been reported recently.
Nothing major here, with maybe the exception of the ramster code can
now be built so it is enabled in the build again, and lots of memory
leaks that people like to have fixed on their systems.
