"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."

Currently when ThumbEE is not enabled (!CONFIG_ARM_THUMBEE) the ThumbEE
register states are not saved/restored at context switch. The default state
of the ThumbEE Ctrl register (TEECR) allows userspace accesses to the
ThumbEE Base Handler register (TEEHBR). This can cause unexpected behaviour
when people use ThumbEE on !CONFIG_ARM_THUMBEE kernels, as well as allowing
covert communication - eg between userspace tasks running inside chroot
jails.
This patch sets up TEECR in order to prevent user-space access to TEEHBR
when !CONFIG_ARM_THUMBEE. In this case, tasks are sent SIGILL if they try to
access TEEHBR.

During booting of cpu1, there is a short window where cpu1
is online, but not active where cpu1 is occupied by waiting
to become active. If cpu0 then decides to schedule something
on cpu1 and wait for it to complete, before cpu0 has set
cpu1 active, we have a deadlock.
Typically it's this CPU frequency transition that happens at
this time, so let's just not wait for it to happen, it will
happen whenever the CPU eventually comes online instead.

handle_IRQ may briefly cause interrupts to be re-enabled during soft IRQ
processing on the exit path, leading to nested handling of VIC interrupts.
Since the current code does not re-read the VIC_IRQ_STATUS register, this
can lead to multiple invocations of the same interrupt handler and
spurious interrupts to be reported.
This patch changes the VIC interrupt dispatching code to re-read the
status register each time, avoiding duplicate invocations of the same
handler.

commit 8878a539ff was done by me
to make the page fault handler retryable as well as interruptible.
Due to this commit, there is a mistake in the way in which
tsk->[maj|min]_flt counter gets incremented for VM_FAULT_ERROR:
If VM_FAULT_ERROR is returned in the fault flags by handle_mm_fault,
then either maj_flt or min_flt will get incremented. This is wrong
as in the case of a VM_FAULT_ERROR we need to be skip ahead to the
error handling code in do_page_fault.
Added a check after the call to __do_page_fault() to check for
(fault & VM_FAULT_ERROR).

A bunch of fixes for regressions (and a few other problems) in 3.4-rc1:
* Fix for regression of mach/io.h cleanup on platforms with PCI or PCMCIA
(adding back the include file on those for now)
* AT91 fixes for usb and spi
* smsc911x ethernet fixes for i.MX
* smsc911x fixes for OMAP
* gpio fixes for Tegra
* A handful of build error and warning fixes for various platforms
* cpufreq kconfig dependencies, build and lowlevel debug fixes for
Samsung platforms
In other words, more or less the regular collection of -rc1/2 type
material. A few of them, in particular the smsc911x for OMAP series, aren't
technically regressions for 3.4, but they're valid fixes and we're still
relatively early in the rc cycle so it seems appropriate to include them.

Many users of debugfs copy the implementation of default_open() when
they want to support a custom read/write function op. This leads to a
proliferation of the default_open() implementation across the entire
tree.
Now that the common implementation has been consolidated into libfs we
can replace all the users of this function with simple_open().
This replacement was done with the following semantic patch:

With commit c334bc1 (ARM: make mach/io.h include optional), PCMCIA was
broken. PCMCIA depends on __io() returning a valid i/o address, and most
ARM platforms require IO_SPACE_LIMIT be set to 0xffffffff for PCMCIA. This
needs a better fix with a fixed i/o address mapping, but for now we just
restore things to the previous behavior.
This fixes at91, omap1, pxa and sa11xx. pxa needs io.h if PCI is enabled,
but PCMCIA is not. sa11xx already has IO_SPACE_LIMIT set to 0xffffffff,
so it doesn't need an io.h.

From Tony Lindgren:
Note that this also contains a set of fixes that are not regressions
or oopses to properly deal with the smsc911x regulator issue.
Basically the regulators must be per board file as the regulators
can also come from drivers, such as twl4030. So it's best to dumb
down gpmc-smsc911x.c to not even care about the regulators.

In the SYSC_TYPE1_XXX_MASK configuration, SYSC_XXX_SHIFT macro
is used which is not defined anywhere in the kernel.
Until now the build was going through successfully, since it
is not being used anywhere in kernel.
This bug got introduced by the commit
358f0e630d ("OMAP3: hwmod: support
to specify the offset position of various SYSCONFIG register bits.")

omap_hwmod_softreset() does not seem to wait for reset status
after doing a softreset. Make it use _ocp_softreset() instead
which does this correctly.

Some modules doesn't have SYSC_HAS_ENAWAKEUP bit available (ex: usb
host uhh module) in absence of this flag
omap_hwmod_enable/disable_wakeup avoids configuring pad mux wakeup
capability.
Configure sysc if SYSC_HAS_ENAWAKEUP is available and for other cases
try enabling/disabling wakeup from mux_pad pins.

All DPLLs except USB are in ALWON powerdomain. Make sure the
clkdm/pwrdm for USB DPLL (l3init) is turned on before attempting
a DPLL relock. So, mark the database accordingly.
Without this fix, it was seen that DPLL relock fails while testing
relock in a loop of USB DPLL.

Commit b1cbdb00d ("OMAP: clockdomain: Wait for powerdomain to be ON
when using clockdomain force wakeup") was assuming that
pwrdm_state_switch() does wait for the powerdomain transition which is
not the case. The missing wait for the powerdomain transition
violates the sequence which the hardware expects, which causes power
management failures on some devices.
Fix this API by adding the pwrdm_wait_transition().
