Pull regmap updates from Mark Brown:
"A surprisingly large series of updates for regmap this time, mostly
due to all the work Stephen Warren has done to add support for MMIO
buses. This wasn't really the target for the framework but it turns
out that there's a reasonable number of cases where it's very helpful
to use the register cache support to allow the register map to remain
available while the device is suspended.
- A MMIO bus implementation, contributed by Stephen Warren. Currently
this is limited to 32 bit systems and native endian registers.
- Support for naming register maps, mainly intended for MMIO devices
with multiple register banks. This was also contributed by Stephen
Warren.
- Support for register striding, again contributed by Stephen Warren
and mainly intended for use with MMIO as typically the registers
will be a fixed size but byte addressed.
- irqdomain support for the generic regmap irq_chip, including support
for dynamically allocate interrupt numbers.
- A function dev_get_regmap() which allows frameworks using regmap to
obtain the regmap for a device from the struct device, making life a
little simpler for them.
- Updates to regmap-irq to support more chips (contributed by Graeme
Gregory) and to use irqdomains.
- Support for devices with 24 bit register addresses.
The striding support collided with all the topic branches so the
branches look a bit messy and eventually I just gave up. There's also
the TI Palmas driver and a couple of other isolated MFD patches that
all depend on new regmap features so are being merged here."

vfs: be even more careful about dentry RCU name lookups
Miklos Szeredi points out that we need to also worry about memory
odering when doing the dentry name comparison asynchronously with RCU.
In particular, doing a rename can do a memcpy() of one dentry name over
another, and we want to make sure that any unlocked reader will always
see the proper terminating NUL character, so that it won't ever run off
the allocation.
Rather than having to be extra careful with the name copy or at lookup
time for each character, this resolves the issue by making sure that all
names that are inlined in the dentry always have a NUL character at the
end of the name allocation. If we do that at dentry allocation time, we
know that no future name copy will ever change that final NUL to
anything else, so there are no memory ordering issues.
So even if a concurrent rename ends up overwriting the NUL character
that terminates the original name, we always know that there is one
final NUL at the end, and there is no worry about the lockless RCU
lookup traversing the name too far.
The out-of-line allocations are never copied over, so we can just make
sure that we write the name (with terminating NULL) and do a write
barrier before we expose the name to anything else by setting it in the
dentry.

vfs: make AIO use the proper rw_verify_area() area helpers
We had for some reason overlooked the AIO interface, and it didn't use
the proper rw_verify_area() helper function that checks (for example)
mandatory locking on the file, and that the size of the access doesn't
cause us to overflow the provided offset limits etc.
Instead, AIO did just the security_file_permission() thing (that
rw_verify_area() also does) directly.
This fixes it to do all the proper helper functions, which not only
means that now mandatory file locking works with AIO too, we can
actually remove lines of code.

Fix blocking allocations called very early during bootup
During early boot, when the scheduler hasn't really been fully set up,
we really can't do blocking allocations because with certain (dubious)
configurations the "might_resched()" calls can actually result in
scheduling events.
We could just make such users always use GFP_ATOMIC, but quite often the
code that does the allocation isn't really aware of the fact that the
scheduler isn't up yet, and forcing that kind of random knowledge on the
initialization code is just annoying and not good for anybody.
And we actually have a the 'gfp_allowed_mask' exactly for this reason:
it's just that the kernel init sequence happens to set it to allow
blocking allocations much too early.
So move the 'gfp_allowed_mask' initialization from 'start_kernel()'
(which is some of the earliest init code, and runs with preemption
disabled for good reasons) into 'kernel_init()'. kernel_init() is run
in the newly created thread that will become the 'init' process, as
opposed to the early startup code that runs within the context of what
will be the first idle thread.
So by the time we reach 'kernel_init()', we know that the scheduler must
be at least limping along, because we've already scheduled from the idle
thread into the init thread.

enhance splice performance on TCP sockets significantly.
a) Reset the offset of the per-socket sendmsg page when we know
we're the only use of the page in linear_to_page().
b) Add facilities such that skb->data can be backed a page rather
than SLAB kmalloc'd memory. In particular devices which were
receiving into linear RX buffers can now end up providing paged
data.
The big result is that code like splice and GRO do not have to copy
any more.
12) Allow a pure sender to more gracefully handle ACK backlogs in TCP.
What can happen at high rates is that the sender hasn't grown his
receive buffer limits at all (he's not receiving data so really
doesn't need to), but the non-data ACKs consume receive buffer
space.
sk_add_backlog() is too aggressive in dropping frames in this case,
so relax it's requirements by using the receive buffer plus the send
buffer limit as the backlog limit instead of just the former.
Also from Eric Dumazet.
13) Add ipv6 support to L2TP, from Benjamin LaHaise, James Chapman, and
Chris Elston.
14) Implement TCP early retransmit (RFC 5827), from Yuchung Cheng.
Basically, we can start fast retransmit before hiting the dupack
threshold under certain conditions.
15) New CODEL active queue management packet scheduler, from Eric
Dumazet based upon initial work by Dave Taht.
Basically, the big feature is that packets are dropped (or ECN bits
are set) based upon how long packets live in the queue, rather than
the queue length (which is what RED uses).

Merge branch 'dentry-cleanups' (dcache access cleanups and optimizations)
This branch simplifies and clarifies the dcache lookup, and allows us to
do certain nice optimizations when comparing dentries. It also cleans
up the interface to __d_lookup_rcu(), especially around passing the
inode information around.
* dentry-cleanups:
vfs: make it possible to access the dentry hash/len as one 64-bit entry
vfs: move dentry name length comparison from dentry_cmp() into callers
vfs: do the careful dentry name access for all dentry_cmp cases

Merge branch 'vfs-cleanups' (random vfs cleanups)
This teaches vfs_fstat() to use the appropriate f[get|put]_light
functions, allowing it to avoid some unnecessary locking for the common
case.
More noticeably, it also cleans up and simplifies the "getname_flags()"
function, which now relies on the architecture strncpy_from_user() doing
all the user access checks properly, instead of hacking around the fact
that on x86 it didn't use to do it right (see commit
92ae03f2ef99: "x86:
merge 32/64-bit versions of 'strncpy_from_user()' and speed it up").
* vfs-cleanups:

that show up high on certain kernel profiles, and just going "Oh, let's
just clean that up".
Architectures that don't supply the #define to fill just the padding

This series sanitizes the interface to unmap_vma(). The crazy interface
annoyed me no end when I was looking at unmap_single_vma(), which we can
spend quite a lot of time in (especially with loads that have a lot of
small fork/exec's: shell scripts etc).
Moving the nr_accounted calculations to where they belong at least
clarifies things a little. I hope to come back to look at the
performance of this later, but if/when I get back to it I at least don't
have to see the crazy interfaces any more.

The way we do that now is overkill. We only needed to use the MMU
cache ops when we had sun4c around because sun4c lacked support for
the "flush" instruction.
But all sun4m and later chips have it so we can use it
unconditionally.
So in the per_cpu_patch() code, get rid of the cache ops invocation,
and instead execute a "flush %reg" after each of the instruction patch
assignments, where %reg is set to the address of the instruction that
was stored into.
Perhaps take the flushi() definition from asm/cacheflush_64.h and
place it into asm/cacheflush.h, then you can simply use that.

regulator: tps65910: use of_node of matched regulator being register
After getting matched regulators by using of_regulator_match(),
initialize the config.of_node of regulator being register with
of_regulator_match.of_node of that regulator.
This is require for supporting regulator consumers in dt.
