Pull USB patches from Greg Kroah-Hartman:
"Here's the big set of USB patches for 3.8-rc1.
Lots of USB host driver cleanups in here, and a bit of a reorg of the
EHCI driver to make it easier for the different EHCI platform drivers
to all work together nicer, which was a reduction in overall code. We
also deleted some unused firmware files, and got rid of the very old
file_storage usb gadget driver that had been broken for a long time.
This means we ended up removing way more code than added, always a
nice thing to see:
310 files changed, 3028 insertions(+), 10754 deletions(-)
Other than that, the usual set of new device ids, driver fixes, gadget
driver and controller updates and the like.
All of these have been in the linux-next tree for a number of weeks.

Pull TTY/Serial merge from Greg Kroah-Hartman:
"Here's the big tty/serial tree set of changes for 3.8-rc1.
Contained in here is a bunch more reworks of the tty port layer from
Jiri and bugfixes from Alan, along with a number of other tty and
serial driver updates by the various driver authors.
Also, Jiri has been coerced^Wconvinced to be the co-maintainer of the
TTY layer, which is much appreciated by me.

Fixed up some trivial conflicts in the staging tree, due to the fwserial
driver having come in both ways (but fixed up a bit in the serial tree),
and the ioctl handling in the dgrp driver having been done slightly
differently (staging tree got that one right, and removed both
TIOCGSOFTCAR and TIOCSSOFTCAR).

Pull staging driver tree merge from Greg Kroah-Hartman:
"Here's the big staging tree merge for 3.8-rc1
There's a lot of patches in here, the majority being the comedi
rework/cleanup that has been ongoing and is causing a huge reduction
in overall code size, which is amazing to watch. We also removed some
older drivers (telephony and rts_pstor), and added a new one (fwserial
which also came in through the tty tree due to tty api changes, take
that one if you get merge conflicts.)
The iio and ipack drivers are moving out of the staging area into
their own part of the kernel as they have been cleaned up sufficiently
and are working well.
Overall, again a reduction of code:

"Here is the "big" char/misc driver patches for 3.8-rc1. I'm starting

Nothing major here, the various __dev* removals, some mei driver

Note, some MFD drivers got added through this tree, and they are also
coming in through the "real" MFD tree as well, due to some major

Pull driver core updates from Greg Kroah-Hartman:
"Here's the large driver core updates for 3.8-rc1.
The biggest thing here is the various __dev* marking removals. This
is going to be a pain for the merge with different subsystem trees, I
know, but all of the patches included here have been ACKed by their
various subsystem maintainers, as they wanted them to go through here.
If this is too much of a pain, I can pull all of them out of this tree
and just send you one with the other fixes/updates and then, after
3.8-rc1 is out, do the rest of the removals to ensure we catch them
all, it's up to you. The merges should all be trivial, and Stephen
has been doing them all in linux-next for a few weeks now quite
easily.
Other than the __dev* marking removals, there's nothing major here,
some firmware loading updates and other minor things in the driver
core.
All of these have (much to Stephen's annoyance), been in linux-next
for a while.

Due to my recent commit (ath9k: allow to load EEPROM
content via firmware API) smatch complains about that
the 'pdata' variable in 'ath9k_hw_init' can be NULL
and it is dereferenced before checking that. That is
absolutely correct.
Check the 'pdata' variable before using it to avoid
a NULL pointer dereference.

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."

In case of rehashing, introduce a global variable 'br_mdb_rehash_seq'
which gets increased every time when rehashing, and assign
net->dev_base_seq + br_mdb_rehash_seq to cb->seq.
In theory cb->seq could be wrapped to zero, but this is not
easy to fix, as net->dev_base_seq is not visible inside
br_mdb_rehash(). In practice, this is rare.

The {read,write}s{b,w,l} operations are not defined by all
architectures and are being removed from the asm-generic/io.h
interface.
This patch replaces the usage of these string functions in the smc911x
accessors with io{read,write}{8,16,32}_rep calls instead.

__napi_gro_receive() is inlined from two call sites for no good reason.
Lets move the prep stuff in a function of its own, called only if/when
needed. This saves 300 bytes on x86 :

Dmitry Kravkov reported packet drops for GRE packets since GRO support
was added.
There is a race in gro_cell_poll() because we call napi_complete()
without any synchronization with a concurrent gro_cells_receive()
Once bug was triggered, we queued packets but did not schedule NAPI
poll.
We can fix this issue using the spinlock protected the napi_skbs queue,
as we have to hold it to perform skb dequeue anyway.
As we open-code skb_dequeue(), we no longer need to mask IRQS, as both
producer and consumer run under BH context.
Bug added in commit c9e6bc644e (net: add gro_cells infrastructure)

Using netdev_alloc_frag() instead of kmalloc() permits better GRO or
TCP coalescing behavior, as skb_gro_receive() doesn't have to fallback
to frag_list overhead.

If we have a read oplock and set a read lock in it, we can't write to the
locked area - so, filemap_fdatawrite may fail with a no information for a
userspace application even if we request a write to non-locked area. Fix
this by populating the page cache without marking affected pages dirty
after a successful write directly to the server.
Also remove CONFIG_CIFS_SMB2 ifdefs because it's suitable for both CIFS
and SMB2 protocols.

This should fix a regression that was introduced when the new mount
option parser went in. Also, when the unc= and prefixpath= options
are provided, check their values against the ones we parsed from
the device string. If they differ, then throw a warning that tells
the user that we're using the values from the unc= option for now,
but that that will change in 3.10.

Currently the code takes care to ensure that the prefixpath has a
leading '/' delimiter. What if someone passes us a prefixpath with a
leading '\\' instead? The code doesn't properly handle that currently
AFAICS.
Let's just change the code to skip over any leading delimiter character
when copying the prepath. Then, fix up the users of the prepath option
to prefix it with the correct delimiter when they use it.
Also, there's no need to limit the length of the prefixpath to 1k. If
the server can handle it, why bother forbidding it?

Make sure we free any existing memory allocated for vol->UNC, just in
case someone passes in multiple unc= options.
Get rid of the check for too long a UNC. The check for >300 bytes seems
arbitrary. We later copy this into the tcon->treeName, for instance and
it's a lot shorter than 300 bytes.
Eliminate an extra kmalloc and copy as well. Just set the vol->UNC
directly with the contents of match_strdup.
Establish that the UNC should be stored with '\\' delimiters. Use
convert_delimiter to change it in place in the vol->UNC.
Finally, move the check for a malformed UNC into
cifs_parse_mount_options so we can catch that situation earlier.

The authority fields are supposed to be represented by a single 48-bit
value. It's also supposed to represent the value as hex if it's equal to
or greater than 2^32. This is documented in MS-DTYP, section 2.4.2.1.
Also, fix up the max string length to account for this fix.

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.

dmapool always calls dma_alloc_coherent() with GFP_ATOMIC flag,
regardless the flags provided by the caller. This causes excessive
pruning of emergency memory pools without any good reason. Additionaly,
on ARM architecture any driver which is using dmapools will sooner or
later trigger the following error:
"ERROR: 256 KiB atomic DMA coherent pool is too small!
Please increase it with coherent_pool= kernel parameter!".
Increasing the coherent pool size usually doesn't help much and only
delays such error, because all GFP_ATOMIC DMA allocations are always
served from the special, very limited memory pool.
This patch changes the dmapool code to correctly use gfp flags provided
by the dmapool caller.

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.
