"We keep collecting defconfig updates in a separate branch mostly to
encourage people to handle them separately and avoid conflicts between
different topics.
Most of these are enablement of new drivers that have come in, or

mostly minor churn of various kinds.

"Driver updates for v4.1. Some of these are for drivers/soc, where we
find more and more SoC-specific drivers these days. Some are for
other driver subsystems where we have received acks from the

The larger parts of this branch are:
- MediaTek support for their PMIC wrapper interface, a high-level
interface for talking to the system PMIC over a dedicated I2C
interface.
- Qualcomm SCM driver has been moved to drivers/firmware. It's used
for CPU up/down and needs to be in a shared location for arm/arm64
common code.

clocks.
- plenty of DT updates for Qualcomm platforms for various IP blocks
- some churn on Tegra due to switch-over to tool-generated pinctrl
data
- misc fixes and updates for Atmel at91 platforms

Pull ARM SoC cleanups from Olof Johansson:
"We've got a fairly large cleanup branch this time. The bulk of this
is removal of non-DT platforms of several flavors:
- Atmel at91 platforms go full-DT, with removal of remaining

- OMAP removes legacy board files for three more platforms
- removal of non-DT mach-msm, newer Qualcomm platforms now live in
mach-qcom
- Freescale i.MX25 also removes non-DT platform support"

example removal of drivers that now lack platforms, etc.

Currently an allyesconfig build [gcc-4.9.1] can generate the following:
WARNING: vmlinux.o(.text.unlikely+0x3864): Section mismatch in
reference from the function cpumask_empty.constprop.3() to the
variable .init.data:nmi_ipi_mask
which comes from the cpumask_empty usage in arch/x86/kernel/nmi_selftest.c.
Normally we would not see a symbol entry for cpumask_empty since it is:
static inline bool cpumask_empty(const struct cpumask *srcp)
however in this case, the variant of the symbol gets emitted when GCC does
constant propagation optimization.
Fix things up so that any locally optimized constprop variants don't warn
when accessing variables that live in the __init sections.

Currently the match() function supports a leading * to match any
prefix and a trailing * to match any suffix. However there currently
is not a combination of both that can be used to target matches of
whole families of functions that share a common substring.
Here we expand the *foo and foo* match to also support *foo* with
the goal of targeting compiler generated symbol names that contain
strings like ".constprop." and ".isra."

Trying to match the SHT_NUL section isn't useful and causes build failures

As Guenter pointed out, we were never really calculating the extable entry
size because the pointer arithmetic was simply wrong. We want to check
we're handling the second relocation in __ex_table to infer an entry size,
but we were using (void*) pointers instead of Elf_Rel[a]* ones.
This fixes the problem by moving that check in the caller (since we can
deal with different types of relocations) and add is_second_extable_reloc()
to make the whole thing more readable.

As Guenter pointed out, we want to assert that extable_entry_size has been
discovered and not the other way around. Moreover, this sanity check is
only valid when we're not dealing with the first relocation in __ex_table,
since we have not discovered the extable entry size at that point.
This was leading to a divide-by-zero on some architectures and make the
build fail.

Merge "urgent omap boot fix for v4.1 if MFD_SYSCON is not set" from Tony
Lindgren:
Urgent pull request for v4.1 to booting for custom kernel
.config files that do not have MFD_SYSCON set.
Omaps now have a dependency to MFD_SYSCON for system control
module generic register area and some clocks with the changes
done in omap-for-v4.1/prcm-dts branch.
This can be pulled on top of omap-for-v4.1/prcm-dts, or into
fixes for v4.1.
We already do have a slight MFD_SYSCON dependency for
REGULATOR_PBIAS for dual voltage MMC cards on the first MMC
bus for many devices, so from that point of view this can
also be merged separately from omap-for-v4.1/prcm-dts.

The only reason to keep parisc's private asm/scatterlist.h was that it
had the macro sg_virt_addr(). Convert all callers to use something else
(sometimes just sg->offset was enough, others should use sg_virt()), and
we can just use the asm-generic scatterlist.h instead.

My 'allmodconfig' build is _almost_ free of warnings, and most of the
remaining ones are for legacy drivers that just do bad things that I
can't find it in my black heart to care too much about. But this one
was just annoying me:
drivers/media/v4l2-core/videobuf2-core.c:3256:26: warning: unused variable ‘fileio’ [-Wunused-variable]
because commit 0e661006370b ("[media] vb2: fix 'UNBALANCED' warnings
when calling vb2_thread_stop()") removed all users of 'fileio' and
instead calls "__vb2_cleanup_fileio(q)" to clean up q->fileio. But the
now unused 'fileio' variable was left around.
