Pull staging/IIO updates from Greg KH:
"Here is the big staging tree update for 4.12-rc1.
It's a big one, adding about 350k new lines of crap^Wcode, mostly all
in a big dump of media drivers from Intel. But there's other new
drivers in here as well, yet-another-wifi driver, new IIO drivers, and
a new crypto accelerator.
We also deleted a bunch of stuff, mostly in patch cleanups, but also
the Android ION code has shrunk a lot, and the Android low memory
killer driver was finally deleted, much to the celebration of the -mm
developers.
All of these have been in linux-next with a few build issues that will
show up when you merge to your tree"

Pull media updates from Mauro Carvalho Chehab:
"Media updates for v4.12-rc1:
- new driver to support mediatek jpeg in hardware codec
- rc-lirc, s5p-cec and st-cec staging drivers got promoted
- hardware histogram support for vsp1 driver
- added Virtual Media Controller driver, to make easier to test the
media controller
- added a new CEC driver (rainshadow-cec)
- removed two staging LIRC drivers for obscure hardware that are too
obsolete
- added support for Intel SR300 Depth camera
- some improvements at CEC and RC core
- lots of driver cleanups, improvements all over the tree
With this series, we're finally getting rid of the LIRC staging
driver. There's just one left (lirc_zilog), with require more care,
as part of its functionality (IR RX) is already provided by another
driver. Work in progress to convert it on the proper way"

Pull GFS2 updates from Bob Peterson:
"We've got ten GFS2 patches for this merge window.
- Andreas Gruenbacher wrote a patch to replace the deprecated call to
rhashtable_walk_init with rhashtable_walk_enter.
- Andreas also wrote a patch to eliminate redundant code in two of
our debugfs sequence files.
- Andreas also cleaned up the rhashtable key ugliness Linus pointed
out during this cycle, following Linus's suggestions.
- Andreas also wrote a patch to take advantage of his new function
rhashtable_lookup_get_insert_fast. This makes glock lookup faster
and more bullet-proof.
- Andreas also wrote a patch to revert a patch in the evict path that
caused occasional deadlocks, and is no longer needed.
- Andrew Price wrote a patch to re-enable fallocate for the rindex
system file to enable gfs2_grow to grow properly on secondary file
system grow operations.
- I wrote a patch to initialize an inode number field to make certain
kernel trace points more understandable.
- I also wrote a patch that makes GFS2 file system "withdraw" work
more like it should by ignoring operations after a withdraw that
would formerly cause a BUG() and kernel panic.
- I also reworked the entire truncate/delete algorithm, scrapping the
old recursive algorithm in favor of a new non-recursive algorithm.
This was done for performance: This way, GFS2 no longer needs to
lock multiple resource groups while doing truncates and deletes of
files that cross multiple resource group boundaries, allowing for
better parallelism. It also solves a problem whereby deleting large
files would request a large chunk of kernel memory, which resulted
in a get_page_from_freelist warning.
- Due to a regression found during testing, I added a new patch to
correct 'GFS2: Prevent BUG from occurring when normal Withdraws
occur'."

Pull orangefs updates from Mike Marshall:
"Orangefs cleanups, fixes and statx support.
Some cleanups:
- remove unused get_fsid_from_ino
- fix bounds check for listxattr
- clean up oversize xattr validation
- do not set getattr_time on orangefs_lookup
- return from orangefs_devreq_read quickly if possible
- do not wait for timeout if umounting
- handle zero size write in debugfs
Bug fixes:
- do not check possibly stale size on truncate
- ensure the userspace component is unmounted if mount fails
- total reimplementation of dir.c
New feature:
- implement statx
The new implementation of dir.c is kind of a big deal, all new code.
It has been posted to fs-devel during the previous rc period, we
didn't get much review or feedback from there, but it has been
reviewed very heavily here, so much so that we have two entire
versions of the reimplementation.
Not only does the new implementation fix some xfstests, but it passes
all the new tests we made here that involve seeking and rewinding and
giant directories and long file names. The new dir code has three
patches itself:
- skip forward to the next directory entry if seek is short
- invalidate stored directory on seek
- count directory pieces correctly"

initramfs: Always do fput() and load modules after rootfs populate
|
|
This bug fixes a regression introduced by patch 0d1c7ae9d8.
The intent of the patch was to stop promoting glocks after a
file system is withdrawn due to a variety of errors, because doing
so results in a BUG(). (You should be able to unmount after a
withdraw rather than having the kernel panic.)
Unfortunately, it also stopped demotions, so glocks could not be
unlocked after withdraw, which means the unmount would hang.
This patch allows function do_xmote to demote locks to an
unlocked state after a withdraw, but not promote them.

- Major improvements to handling of system reset interrupts,
correctly treating them as NMIs, giving them a dedicated stack and
using a new hypervisor call to trigger them, all of which should
aid debugging and robustness.

While honouring the DMA_ATTR_FORCE_CONTIGUOUS on arm64 (commit
44176bb38fa4: "arm64: Add support for DMA_ATTR_FORCE_CONTIGUOUS to
IOMMU"), the existing uses of dma_mmap_attrs() and dma_get_sgtable()
have been broken by passing a physically contiguous vm_struct with an
invalid pages pointer through the common iommu API.
Since the coherent allocation with DMA_ATTR_FORCE_CONTIGUOUS uses CMA,
this patch simply reuses the existing swiotlb logic for mmap and
get_sgtable.
Note that the current implementation of get_sgtable (both swiotlb and
iommu) is broken if dma_declare_coherent_memory() is used since such
memory does not have a corresponding struct page. To be addressed in a
subsequent patch.

In OpenRISC we do not have a bootloader passed initrd, but the built in
initramfs does contain the /init and other binaries, including modules.
The previous commit 08865514805d2 ("initramfs: finish fput() before
accessing any binary from initramfs") made a change to only call fput()
if the bootloader initrd was available, this caused intermittent crashes
for OpenRISC.
This patch changes the fput() to happen unconditionally if any rootfs is
loaded. Also, I added some comments to make it a bit more clear why we
call unpack_to_rootfs() multiple times.

drm/tegra: Changes for v4.12-rc1
This contains various fixes to the host1x driver as well as a plug for a
leak of kernel pointers to userspace.
A fairly big addition this time around is the Video Image Composer (VIC)
support that can be used to accelerate some 2D and image compositing
operations.
Furthermore the driver now supports FB modifiers, so we no longer rely
on a custom IOCTL to set those.
Finally this contains a few preparatory patches for Tegra186 support
which unfortunately didn't quite make it this time, but will hopefully
be ready for v4.13.

Pull USB updates from Greg KH:
"Here is the big USB patchset for 4.12-rc1.
Lots of good stuff here, after many many many attempts, the kernel
finally has a working typeC interface, many thanks to Heikki and
Guenter and others who have taken the time to get this merged. It
wasn't an easy path for them at all.
There's also a staging driver that uses this new api, which is why
it's coming in through this tree.
Along with that, there's the usual huge number of changes for gadget
drivers, xhci, and other stuff. Johan also finally refactored pretty
much every driver that was looking at USB endpoints to do it in a
common way, which will help prevent any "badly-formed" devices from
causing problems in drivers. That too wasn't a simple task.
All of these have been in linux-next for a while with no reported
issues"

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.12 kernel cycle.
Core changes:
- Return NULL from gpiod_get_optional() when GPIOLIB is disabled.
This was a much discussed change. It affects use cases where people
write drivers that might or might not be using GPIO resources. I
have decided that this is the lesser evil right now.
- Make gpiod_count() behave consistently across different hardware
descriptions.
- Fix the syntax around open drain/open source to not infer active
high/low semantics.
New drivers:
- A new single-register fixed-direction framework driver for hardware
that have lines controlled by a single register that just work in
one direction (out or in), including IRQ support.
- Support the Fintek F71889A GPIO SuperIO controller.
- Support the National NI 169445 MMIO GPIO.
- Support for the X-Gene derivative of the DWC GPIO controller
- Support for the Rohm BD9571MWV-M PMIC GPIO controller.
- Refactor the Gemini GPIO driver to a generic Faraday FTGPIO driver
and replace both the Gemini and the Moxa ART custom drivers with
this driver.
Driver improvements:
- A whole slew of drivers have their spinlocks chaned to raw
spinlocks as they provide irqchips, and thus we are progressing on
realtime compliance.
- Use devm_irq_alloc_descs() in a slew of drivers, getting managed
resources.
- Support for the embedded PWM controller inside the MVEBU driver.
- Debounce, open source and open drain support for the Aspeed driver.
- Misc smaller fixes like spelling and syntax and whatnot"

If userspace seeks to a position in the stream which is not correct, it
would have returned EIO because the data in the buffer at that offset
would be incorrect. This and the userspace daemon returning a corrupt
directory are indistinguishable.
Now if the data does not look right, skip forward to the next chunk and
try again. The motivation is that if the directory changes, an
application may seek to a position that was valid and no longer is valid.
It is not yet possible for a directory to change.

Due to the way I did the RX bitrate conversions in mac80211 with
spatch, going setting flags to setting the value, many drivers now
don't set the bandwidth value for 20 MHz, since with the flags it
wasn't necessary to (there was no 20 MHz flag, only the others.)
Rather than go through and try to fix up all the drivers, instead
renumber the enum so that 20 MHz, which is the typical bandwidth,
actually has the value 0, making those drivers all work again.
If VHT was hit used with a driver not reporting it, e.g. iwlmvm,
this manifested in hitting the bandwidth warning in
cfg80211_calculate_bitrate_vht().

Andrey reported a crash on init_net.ipv6.ip6_null_entry->rt6i_idev
since it is always NULL.
This is clearly wrong, we have code to initialize it to loopback_dev,
unfortunately the order is still not correct.
loopback_dev is registered very early during boot, we lose a chance
to re-initialize it in notifier. addrconf_init() is called after
ip6_route_init(), which means we have no chance to correct it.
Fix it by moving this initialization explicitly after
ipv6_add_dev(init_net.loopback_dev) in addrconf_init().

IFLA_PHYS_PORT_NAME is a string attribute, so terminate it with \0.
Otherwise libnl3 fails to validate netlink messages with this attribute.
"ip -detail a" assumes too that the attribute is NUL-terminated when
printing it. It often was, due to padding.
I noticed this as libvirtd failing to start on a system with sfc driver
after upgrading it to Linux 4.11, i.e. when sfc added support for

Under fuzzer stress, it is possible that a child gets a non NULL
fastopen_req pointer from its parent at accept() time, when/if parent
morphs from listener to active session.
We need to make sure this can not happen, by clearing the field after
socket cloning.

Since netif_carrier_on() will do nothing if device's
carrier is already on, so it's unnecessary to do
carrier status check.
It's the same for netif_carrier_off().

Pull tracing updates from Steven Rostedt:
"New features for this release:
- Pretty much a full rewrite of the processing of function plugins.
i.e. echo do_IRQ:stacktrace > set_ftrace_filter
- The rewrite was needed to add plugins to be unique to tracing
instances. i.e. mkdir instance/foo; cd instances/foo; echo
do_IRQ:stacktrace > set_ftrace_filter The old way was written very
hacky. This removes a lot of those hacks.
- New "function-fork" tracing option. When set, pids in the
set_ftrace_pid will have their children added when the processes
with their pids listed in the set_ftrace_pid file forks.
- Exposure of "maxactive" for kretprobe in kprobe_events
- Allow for builtin init functions to be traced by the function
tracer (via the kernel command line). Module init function tracing
will come in the next release.
- Added more selftests, and have selftests also test in an instance"

git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk
Pull printk updates from Petr Mladek:
- There is a situation when early console is not deregistered because
the preferred one matches a wrong entry. It caused messages to appear
twice.
This is the 2nd attempt to fix it. The first one was wrong, see the
commit c6c7d83b9c9e ('Revert "console: don't prefer first registered
if DT specifies stdout-path"').
The fix is coupled with some small code clean up. Well, the console
registration code would deserve a big one. We need to think about it.
- Do not lose information about the preemtive context when the console
semaphore is re-taken.
- Do not block CPU hotplug when someone else is already pushing
messages to the console.
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk:
printk: fix double printing with earlycon
printk: rename selected_console -> preferred_console

This makes a bug uniquely identifiable by the first report line. To
account for removing of the unexpected shadow value, print shadow bytes
