Here's the big staging and iio driver update for 4.7-rc1.
I think we almost broke even with this release, only adding a few more
lines than we removed, which isn't bad overall given that there's a
bunch of new iio drivers added. The Lustre developers seem to have
woken up from their sleep and have been doing a great job in cleaning up
the code and pruning unused or old cruft, the filesystem is almost
readable :)
Other than that, just a lot of basic coding style cleanups in the churn.
All have been in linux-next for a while with no reported issues.

Core infrastructural changes:
- Support for natively single-ended GPIO driver stages. This
means that if the hardware has registers to configure open
drain or open source configuration, we use that rather than
(as we did before) try to emulate it by switching the line
to an input to get high impedance. This is also documented
throughly in Documentation/gpio/driver.txt for those of you
who did not understand one word of what I just wrote.
- Start to do away with the unnecessarily complex and
unitelligible ARCH_REQUIRE_GPIOLIB and
ARCH_WANT_OPTIONAL_GPIOLIB, another evolutional artifact from
the time when the GPIO subsystem was unmaintained. Archs can
now just select GPIOLIB and be done with it, cleanups to
arches will trickle in for the next kernel. Some minor archs
ACKed the changes immediately so these are included in this
pull request.
- Advancing the use of the data pointer inside the GPIO device
for storing driver data by switching the PowerPC, Super-H
Unicore and a few other subarches or subsystem drivers in
ALSA SoC, Input, serial, SSB, staging etc to use it.
- The initialization now reads the input/output state of the
GPIO lines, so that each GPIO descriptor knows - if this
callback is implemented - whether the line is input or
output. This also reflects nicely in userspace "lsgpio".
- It is now possible to name GPIO producer names, line names,
from the device tree. (Platform data has been supported for
a while.) I bet we will get a similar mechanism for ACPI
one of those days. This makes is possible to get sensible
producer names for e.g. GPIO rails in "lsgpio" in userspace.
New drivers:
- New driver for the Loongson1.
- The XLP driver now supports Broadcom Vulcan ARM64.
- The IT87 driver now supports IT8620 and IT8628.
- The PCA953X driver now supports Galileo Gen2.
Driver improvements:
- MCP23S08 was switched to use the gpiolib irqchip helpers and
now also suppors level-triggered interrupts.
- 74x164 and RCAR now supports the .set_multiple() callback
- AMDPT was converted to use generic GPIO.
- TC3589x, TPS65218, SX150X, F7188X, MENZ127, VX855, WM831X, WM8994
support the new single ended callback for open drain
and in some cases open source.
- Implement the .get_direction() callback for a few more drivers
like PL061, Xgene.
Cleanups:
- Paul Gortmaker combed through the drivers and de-modularized
those who are not really modules.
- Move the GPIO poweroff DT bindings to the power subdir where
they belong.
- Rename gpio-generic.c to gpio-mmio.c, which is much more to the
point. That's what it is handling, nothing more, nothing less.

Pull parallel filesystem directory handling update from Al Viro.
This is the main parallel directory work by Al that makes the vfs layer
able to do lookup and readdir in parallel within a single directory.
That's a big change, since this used to be all protected by the
directory inode mutex.
The inode mutex is replaced by an rwsem, and serialization of lookups of
a single name is done by a "in-progress" dentry marker.
The series begins with xattr cleanups, and then ends with switching
filesystems over to actually doing the readdir in parallel (switching to
the "iterate_shared()" that only takes the read lock).
A more detailed explanation of the process from Al Viro:
"The xattr work starts with some acl fixes, then switches ->getxattr to
passing inode and dentry separately. This is the point where the
things start to get tricky - that got merged into the very beginning
of the -rc3-based #work.lookups, to allow untangling the
security_d_instantiate() mess. The xattr work itself proceeds to
switch a lot of filesystems to generic_...xattr(); no complications
there.
After that initial xattr work, the series then does the following:
- untangle security_d_instantiate()
- convert a bunch of open-coded lookup_one_len_unlocked() to calls of
that thing; one such place (in overlayfs) actually yields a trivial
conflict with overlayfs fixes later in the cycle - overlayfs ended
up switching to a variant of lookup_one_len_unlocked() sans the
permission checks. I would've dropped that commit (it gets
overridden on merge from #ovl-fixes in #for-next; proper resolution
is to use the variant in mainline fs/overlayfs/super.c), but I
didn't want to rebase the damn thing - it was fairly late in the
cycle...
- some filesystems had managed to depend on lookup/lookup exclusion
for *fs-internal* data structures in a way that would break if we
relaxed the VFS exclusion. Fixing hadn't been hard, fortunately.
- core of that series - parallel lookup machinery, replacing
->i_mutex with rwsem, making lookup_slow() take it only shared. At
that point lookups happen in parallel; lookups on the same name
wait for the in-progress one to be done with that dentry.
Surprisingly little code, at that - almost all of it is in
fs/dcache.c, with fs/namei.c changes limited to lookup_slow() -
making it use the new primitive and actually switching to locking
shared.
- parallel readdir stuff - first of all, we provide the exclusion on
per-struct file basis, same as we do for read() vs lseek() for
regular files. That takes care of most of the needed exclusion in
readdir/readdir; however, these guys are trickier than lookups, so
I went for switching them one-by-one. To do that, a new method
'->iterate_shared()' is added and filesystems are switched to it
as they are either confirmed to be OK with shared lock on directory
or fixed to be OK with that. I hope to kill the original method
come next cycle (almost all in-tree filesystems are switched
already), but it's still not quite finished.
- several filesystems get switched to parallel readdir. The
interesting part here is dealing with dcache preseeding by readdir;
that needs minor adjustment to be safe with directory locked only
shared.
Most of the filesystems doing that got switched to in those
commits. Important exception: NFS. Turns out that NFS folks, with
their, er, insistence on VFS getting the fuck out of the way of the
Smart Filesystem Code That Knows How And What To Lock(tm) have
grown the locking of their own. They had their own homegrown
rwsem, with lookup/readdir/atomic_open being *writers* (sillyunlink
is the reader there). Of course, with VFS getting the fuck out of
the way, as requested, the actual smarts of the smart filesystem
code etc. had become exposed...
- do_last/lookup_open/atomic_open cleanups. As the result, open()
without O_CREAT locks the directory only shared. Including the
->atomic_open() case. Backmerge from #for-linus in the middle of
that - atomic_open() fix got brought in.
- then comes NFS switch to saner (VFS-based ;-) locking, killing the
homegrown "lookup and readdir are writers" kinda-sorta rwsem. All
exclusion for sillyunlink/lookup is done by the parallel lookups
mechanism. Exclusion between sillyunlink and rmdir is a real rwsem
now - rmdir being the writer.
Result: NFS lookups/readdirs/O_CREAT-less opens happen in parallel
now.
- the rest of the series consists of switching a lot of filesystems
to parallel readdir; in a lot of cases ->llseek() gets simplified
as well. One backmerge in there (again, #for-linus - rockridge
fix)"

In del_scsipending_ent(), the error-path and main-path were switched, so
the error-path is handled like 'if (err) return;', and the main-path flows
down the left margin. This also allowed us to remove the initialization of
"sent".

Previously, if visorhba ever failed to create its thread, it would have
subsequently attempted to do a kthread_stop() on an invalid task_struct
pointer. This was fixed via the new visor_thread_stop() function, which
validates the task_struct pointer before doing the kthread_stop().
Also, the other thread-related fields in visor_thread_info (has_stopped
and id) were not being used, so visor_thead_info was just removed.
We also now spit out an error message if thread creation fails.

Enables support of different map-on-demand values per NI. This is
required to support OPA coexistence with MLX5 cards. MLX5 does not
support FMR, which is enabled via map-on-demand. However OPA's
performance is greatly enahanced when FMR is enabled. In order
to enable coexistence of both of these two types of cards we
need to be able to set different map-on-demand values for both NIs.
This patch also lays the ground work for other per NI tunables to
be added in future patches.
