Pull pinctrl changes from Linus Walleij:
"These are the first and major pinctrl changes for the v3.8 merge
cycle. Some of this is used as merge base for other trees so I better
be early on the trigger.
As can be seen from the diffstat the major changes are:
- A big conversion of the AT91 pinctrl driver and the associated ACKed
platform changes under arch/arm/max-at91 and its device trees. This
has been coordinated with the AT91 maintainers to go in through the
pinctrl tree.
- A larger chunk of changes to the SPEAr drivers and the addition of
the "plgpio" driver for the SPEAr as well.
- The removal of the remnants of the Nomadik driver from the arch/arm
tree and fusion of that into the Nomadik driver and platform data
header files.
- Some local movement in the Marvell MVEBU drivers, these now have
their own subdirectory.
- The addition of a chunk of code to gpiolib under drivers/gpio to
register gpio-to-pin range mappings from the GPIO side of things.
This has been requested by Grant Likely and is now implemented, it
is particularly useful for device tree work.
Then we have incremental updates all over the place, many of these are
cleanups and fixes from Axel Lin who has done a great job of removing
minor mistakes and compilation annoyances."

This commit changes the CMA early initialization code to use phys_addr_t
for representing physical addresses instead of unsigned long.
Without this change, among other things, dma_declare_contiguous() simply
discards any memory regions whose address is not representable as unsigned
long.
This is a problem on 32-bit PAE machines where unsigned long is 32-bit
but physical address space is larger.

Some gate clocks have special needs which must be handled during the
disable-unused clocks sequence. These needs might be driven by software
due to the fact that we're disabling a clock outside of the normal
clk_disable path and a clk's enable_count will not be accurate. On the
other hand a specific hardware programming sequence might need to be
followed for this corner case.
This change is needed for the upcoming OMAP port to the common clock
framework. Specifically, it is undesirable to treat the disable-unused
path identically to the normal clk_disable path since other software
layers are involved. In this case OMAP's clockdomain code throws WARNs
and bails early due to the clock's enable_count being set to zero. A
custom callback mitigates this problem nicely.

This reverts commits a50915394f and
d7c3b937bd.
This is a revert of a revert of a revert. In addition, it reverts the
even older i915 change to stop using the __GFP_NO_KSWAPD flag due to the
original commits in linux-next.
It turns out that the original patch really was bogus, and that the
original revert was the correct thing to do after all. We thought we
had fixed the problem, and then reverted the revert, but the problem
really is fundamental: waking up kswapd simply isn't the right thing to
do, and direct reclaim sometimes simply _is_ the right thing to do.
When certain allocations fail, we simply should try some direct reclaim,
and if that fails, fail the allocation. That's the right thing to do
for THP allocations, which can easily fail, and the GPU allocations want
to do that too.
So starting kswapd is sometimes simply wrong, and removing the flag that
said "don't start kswapd" was a mistake. Let's hope we never revisit
this mistake again - and certainly not this many times ;)

commit 2e71a6f808 (net: gro: selective flush of packets) added
a bug for skbs using frag_list. This part of the GRO stack is rarely
used, as it needs skb not using a page fragment for their skb->head.
Most drivers do use a page fragment, but some of them use GFP_KERNEL
allocations for the initial fill of their RX ring buffer.
napi_gro_flush() overwrite skb->prev that was used for these skb to
point to the last skb in frag_list.
Fix this using a separate field in struct napi_gro_cb to point to the
last fragment.

This fixes a regression in 3.7-rc, which has since gone into stable.
Commit 00442ad04a ("mempolicy: fix a memory corruption by refcount
imbalance in alloc_pages_vma()") changed get_vma_policy() to raise the
refcount on a shmem shared mempolicy; whereas shmem_alloc_page() went
on expecting alloc_page_vma() to drop the refcount it had acquired.
This deserves a rework: but for now fix the leak in shmem_alloc_page().
Hugh: shmem_swapin() did not need a fix, but surely it's clearer to use
the same refcounting there as in shmem_alloc_page(), delete its onstack
mempolicy, and the strange mpol_cond_copy() and __mpol_cond_copy() -
those were invented to let swapin_readahead() make an unknown number of
calls to alloc_pages_vma() with one mempolicy; but since 00442ad04a,
alloc_pages_vma() has kept refcount in balance, so now no problem.

The OLPC XO-1.75 laptop includes a SDHCI controller which is 1.8v
capable, and it truthfully reports so in its capabilities. This
alternate voltage is used for driving new "UHS-I" SD cards at their
full speed.
However, what the controller doesn't know is that the motherboard
physically doesn't have a 1.8v supply available.
Add a quirk so that systems such as this one can override disable
1.8v support, adding support for UHS-I cards (by running them at
3.3v).
This avoids a problem where the system would first try to run the
card at 1.8v, fail, and then not be able to fully reset the card
to retry at the normal 3.3v voltage.
This is more appropriate than using the MISSING_CAPS quirk, which
is intended for cases where the SDHCI controller is actually lying
about its capabilities, and would force us to somehow override both
caps words from another source.
