In MAX77686 PMIC two regulators dedicated for eMMC memory can be
controlled both by I2C interface and a GPIO pin, with the resulting
regulator state being a logical OR of both. Since the GPIO control is
used both by the kernel and the lowest level bootloader at reset, the
regulator should be disabled by I2C control to allow it to be turned off
by GPIO control.

Pull audit updates from Eric Paris:
"So this change across a whole bunch of arches really solves one basic
problem. We want to audit when seccomp is killing a process. seccomp
hooks in before the audit syscall entry code. audit_syscall_entry
took as an argument the arch of the given syscall. Since the arch is
part of what makes a syscall number meaningful it's an important part
of the record, but it isn't available when seccomp shoots the
syscall...
For most arch's we have a better way to get the arch (syscall_get_arch)
So the solution was two fold: Implement syscall_get_arch() everywhere
there is audit which didn't have it. Use syscall_get_arch() in the
seccomp audit code. Having syscall_get_arch() everywhere meant it was
a useless flag on the stack and we could get rid of it for the typical
syscall entry.
The other changes inside the audit system aren't grand, fixed some
records that had invalid spaces. Better locking around the task comm
field. Removing some dead functions and structs. Make some things
static. Really minor stuff"

Pull MTD update from Brian Norris:
"Sorry for delaying this a bit later than usual. There's one mild
regression from 3.16 that was noticed during the 3.17 cycle, and I
meant to send a fix for it along with this pull request. I'll
probably try to queue it up for a later pull request once I've had a
better look at it, hopefully by -rc2 at the latest.
Summary for this pull:
NAND
- Cleanup for Denali driver
- Atmel: add support for new page sizes
- Atmel: fix up 'raw' mode support
- Atmel: miscellaneous cleanups
- New timing mode helpers for non-ONFI NAND
- OMAP: allow driver to be (properly) built as a module

Explicitly set the dr_mode for the second dwc3 controller on the
Arndale Octa board to host mode. This is required to ensure the
controller is initialized in the right mode if the kernel is build
with USB gadget support.

In case the optional dr_mode property isn't set in the dwc3 nodes the
the controller will go into OTG mode if both USB host and USB gadget
functionality are enabled in the kernel configuration. Unfortunately
this results in USB not working on exynos5420-peach-pit and
exynos5800-peach-pi with such a kernel configuration unless manually
change the mode. To resolve that explicitly configure the dual role
mode as host.

The EIRSR and ELRSR registers are 32-bit registers on GICv2, and we
store these as an array of two such registers on the vgic vcpu struct.
However, we access them as a single 64-bit value or as a bitmap pointer
in the generic vgic code, which breaks BE support.
Instead, store them as u64 values on the vgic structure and do the
word-swapping in the assembly code, which already handles the byte order
for BE systems.

Pull percpu consistent-ops changes from Tejun Heo:
"Way back, before the current percpu allocator was implemented, static
and dynamic percpu memory areas were allocated and handled separately
and had their own accessors. The distinction has been gone for many
years now; however, the now duplicate two sets of accessors remained
with the pointer based ones - this_cpu_*() - evolving various other
operations over time. During the process, we also accumulated other
inconsistent operations.
This pull request contains Christoph's patches to clean up the
duplicate accessor situation. __get_cpu_var() uses are replaced with
with this_cpu_ptr() and __this_cpu_ptr() with raw_cpu_ptr().
Unfortunately, the former sometimes is tricky thanks to C being a bit
messy with the distinction between lvalues and pointers, which led to
a rather ugly solution for cpumask_var_t involving the introduction of
this_cpu_cpumask_var_ptr().
This converts most of the uses but not all. Christoph will follow up
with the remaining conversions in this merge window and hopefully
remove the obsolete accessors"

Finally some fixes to the locking around the clock debugfs stuff was

When creating or moving a memslot, make sure the IPA space is within the
addressable range of the guest. Otherwise, user space can create too
large a memslot and KVM would try to access potentially unallocated page
table entries when inserting entries in the Stage-2 page tables.

This patch adds the necessary support for all host kernel PGSIZE and
VA_SPACE configuration options for both EL2 and the Stage-2 page tables.
However, for 40bit and 42bit PARange systems, the architecture mandates
that VTCR_EL2.SL0 is maximum 1, resulting in fewer levels of stage-2
pagge tables than levels of host kernel page tables. At the same time,
systems with a PARange > 42bit, we limit the IPA range by always setting
VTCR_EL2.T0SZ to 24.
To solve the situation with different levels of page tables for Stage-2
translation than the host kernel page tables, we allocate a dummy PGD
with pointers to our actual inital level Stage-2 page table, in order
for us to reuse the kernel pgtable manipulation primitives. Reproducing
all these in KVM does not look pretty and unnecessarily complicates the
32-bit side.
Systems with a PARange < 40bits are not yet supported.
[ I have reworked this patch from its original form submitted by
Jungseok to take the architecture constraints into consideration.
There were too many changes from the original patch for me to
preserve the authorship. Thanks to Catalin Marinas for his help in
figuring out a good solution to this challenge. I have also fixed
various bugs and missing error code handling from the original
patch. - Christoffer ]
