When submitting a command for userspace, input and output payload bounce
buffers are allocated. For a given command, both input and output
buffers may exist and so when allocation of the input buffer fails, the
output buffer must be freed too.
As far as I can tell, userspace can't easily exploit the leak to OOM a
machine unless the machine was already near OOM state.

Pull powerpc updates from Michael Ellerman:
- A large series adding wrappers for our interrupt handlers, so that
irq/nmi/user tracking can be isolated in the wrappers rather than
spread in each handler.
- Conversion of the 32-bit syscall handling into C.
- A series from Nick to streamline our TLB flushing when using the
Radix MMU.
- Switch to using queued spinlocks by default for 64-bit server CPUs.
- A rework of our PCI probing so that it happens later in boot, when
more generic infrastructure is available.
- Two small fixes to allow 32-bit little-endian processes to run on
64-bit kernels.
- Other smaller features, fixes & cleanups.

You should use KCFLAGS to pass additional compiler flags from the
command line. Using EXTRA_CFLAGS is wrong.
EXTRA_CFLAGS is supposed to specify flags applied only to the current
Makefile (and now deprecated in favor of ccflags-y).
It is still used in arch/mips/kvm/Makefile (and possibly in external
modules too). Passing EXTRA_CFLAGS from the command line overwrites
it and breaks the build.
I also fixed drivers/gpu/drm/tilcdc/Makefile because commit 816175dd1fd7
("drivers/gpu/drm/tilcdc: Makefile, only -Werror when no -W* in
EXTRA_CFLAGS") was based on the same misunderstanding.

There exists a race where we can be attempting to create a new nbd
configuration while a previous configuration is going down, both
configured with DESTROY_ON_DISCONNECT. Normally devices all have a
reference of 1, as they won't be cleaned up until the module is torn
down. However with DESTROY_ON_DISCONNECT we'll make sure that there is
only 1 reference (generally) on the device for the config itself, and
then once the config is dropped, the device is torn down.
The race that exists looks like this
TASK1 TASK2
nbd_genl_connect()
idr_find()
refcount_inc_not_zero(nbd)
* count is 2 here ^^
nbd_config_put()
nbd_put(nbd) (count is 1)
setup new config
check DESTROY_ON_DISCONNECT
put_dev = true
if (put_dev) nbd_put(nbd)
* free'd here ^^
In nbd_genl_connect() we assume that the nbd ref count will be 2,
however clearly that won't be true if the nbd device had been setup as
DESTROY_ON_DISCONNECT with its prior configuration. Fix this by getting
rid of the runtime flag to check if we need to mess with the nbd device
refcount, and use the device NBD_DESTROY_ON_DISCONNECT flag to check if
we need to adjust the ref counts. This was reported by syzkaller with
the following kasan dump

Currently if an AVF driver doesn't account for the possibility of a
port VLAN when determining its max packet size then packets at MTU will
be dropped. It is not the VF driver's responsibility to account for a
port VLAN so fix this. To fix this, do the following:
1. Add a function that determines the max packet size a VF is allowed by
using the port's max packet size and whether the VF is in a port
VLAN. If a port VLAN is configured then a VF's max packet size will
always be the port's max packet size minus VLAN_HLEN. Otherwise it
will be the port's max packet size.
2. Use this function to verify the max packet size from the VF.
3. If there is a port VLAN configured then add 4 bytes (VLAN_HLEN) to
the VF's max packet size configuration.
Also, the VIRTCHNL_OP_GET_VF_RESOURCES message provides the capability
to communicate a VF's max packet size. Use the new function for this
purpose.

Currently the PF will only set a trusted VF as the default VSI when it
requests FLAG_VF_UNICAST_PROMISC over VIRTCHNL. However, when
FLAG_VF_MULTICAST_PROMISC is set it's expected that the trusted VF will
see multicast packets that don't have a matching destination MAC in the
devices internal switch. Fix this by setting the trusted VF as the
default VSI if either FLAG_VF_UNICAST_PROMISC or
FLAG_VF_MULTICAST_PROMISC is set.

Pull device mapper updates from Mike Snitzer:
- Fix DM integrity's HMAC support to provide enhanced security of
internal_hash and journal_mac capabilities.
- Various DM writecache fixes to address performance, fix table output
to match what was provided at table creation, fix writing beyond end
of device when shrinking underlying data device, and a couple other
small cleanups.
- Add DM crypt support for using trusted keys.
- Fix deadlock when swapping to DM crypt device by throttling number of
in-flight REQ_SWAP bios. Implemented in DM core so that other
bio-based targets can opt-in by setting ti->limit_swap_bios.
- Fix various inverted logic bugs in the .iterate_devices callout
functions that are used to assess if specific feature or capability
is supported across all devices being combined/stacked by DM.
- Fix DM era target bugs that exposed users to lost writes or memory
leaks.
- Add DM core support for passing through inline crypto support of
underlying devices. Includes block/keyslot-manager changes that
enable extending this support to DM.

calculation cleanup, cleanup conditional zoned support in targets,

In the driver currently, we are reporting max number of TCs
to the DCBNL callback as a kernel define set to 8. This is
preventing userspace applications performing DCBx to correctly
down map the TCs from requested to actual values.
Report the actual max TC value to userspace from the capability
struct.

"This is all driver updates, the majority of which is a bunch of new
Qualcomm clk drivers that dominate the diffstat because we add support

The other big change is the removal of various clk drivers that are no
longer used now that the kernel is dropping support for those SoCs.
Beyond that there's the usual non-critical fixes for existing drivers
and a good number of patches from Lee Jones that cleanup a bunch of
W=1 enabled builds.

Pull spi updates from Mark Brown:
"The main focus of this release from a framework point of view has been
spi-mem where we've acquired support for a few new hardware features
which enable better performance on suitable hardware.
Otherwise mostly thanks to Arnd's cleanup efforts on old platforms
we've removed several obsolete drivers which just about balance out
the newer drivers we've added this cycle.
Summary:
- Allow drivers to flag if they are unidirectional.
- Support for DTR mode and hardware acceleration of dummy cycles in
spi-mem.
- Support for Allwinder H616, Intel Lightning Mountain, nVidia Tegra
QuadSPI, Realtek RTL838x and RTL839x.
- Removal of obsolete EFM32, Txx9 and SIRF Prima and Atlas drivers"

them are all over the place.
- removal of the efm32, sirf, u300, and zte zx bus drivers because of
platform removal. So, we have a pleasant diffstat this time.
- first set of cleanups in the I2C core as preparation to increase
maximum length of SMBus transfers to 255 (as specified in the new
standard). Better documentation of struct i2c_msg and its flags stand
out here.
- the testunit can now respond to SMBus block process calls which is
the testcase when implementing the above new maximum length.

There's an I/O error on fsync() in a detached loop device
if it has been previously attached.
The issue is write cache is enabled in the attach path in
loop_configure() but it isn't disabled in the detach path;
thus it remains enabled in the block device regardless of
whether it is attached or not.
Now fsync() can get an I/O request that will just be failed
later in loop_queue_rq() as device's state is not 'Lo_bound'.
So, disable write cache in the detach path.
Do so based on the queue flag, not the loop device flag for
read-only (used to enable) as the queue flag can be changed
via sysfs even on read-only loop devices (e.g., losetup -r.)
Test-case:
# DEV=/dev/loop7
# IMG=/tmp/image
# truncate --size 1M $IMG
# losetup $DEV $IMG
# losetup -d $DEV
Before:
# strace -e fsync parted -s $DEV print 2>&1 | grep fsync
fsync(3) = -1 EIO (Input/output error)
Warning: Error fsyncing/closing /dev/loop7: Input/output error

If source_support is set the platform supports PSR so no need to check
it again at every CAN_PSR().
Also removing the intel_dp_is_edp() calls, if sink_support is set
the sink connected is for sure a eDP panel.

intel_psr2_program_trans_man_trk_ctl()
There is no support for two pipes one transcoder for PSR and if we had
that the current code should not use cpu_transcoder.
Also I can't see a scenario where crtc_state->enable_psr2_sel_fetch is
set and PSR is not enabled and if by a bug it happens PSR HW will just
ignore any value in set in PSR2_MAN_TRK_CTL.
So dropping all the rest and keeping the same behavior that we have
with intel_psr2_program_plane_sel_fetch().
