"There are four items:
- A patch to fix X.509 certificate gathering. The problem was that I
was coming up with a different path for signing_key.x509 in the
build directory if it didn't exist to if it did exist. This meant
that the X.509 cert container object file would be rebuilt on the
second rebuild in a build directory and the kernel would get
relinked.
- Unconditionally remove files generated by SYSTEM_TRUSTED_KEYRING=y
when doing make mrproper.
- Actually initialise the persistent-keyring semaphore for
init_user_ns. I have no idea why this works at all for users in
the base user namespace unless it's something to do with systemd
containerising the system.

...the problem is that the receive path falls back to cpu-copy in
several locations and this trace is just one of the areas. A few
options were considered to fix this:
1/ sync all dma whenever a cpu copy branch is taken
2/ modify the page fault handler to hold off while dma is in-flight
Option 1 adds yet more cpu overhead to an "offload" that struggles to compete
with cpu-copy. Option 2 adds checks for behavior that is already documented as
broken when using get_user_pages(). At a minimum a debug mode is warranted to
catch and flag these violations of the dma-api vs get_user_pages().
Thanks to David for his reproducer.

On the Dell machines with codec whose Subsystem Id is 0x10280640,
no external microphone can be detected when plugging a 3-ring headset.
Using ALC255_FIXUP_DELL1_MIC_NO_PRESENCE can fix this problem.
The codec (Vendor ID: 0x10ec0255) on the machine belongs to alc_269

Commit caaa4c804f ("KVM: PPC: Book3S HV: Fix physical address
calculations") unfortunately resulted in some low-order address bits
getting dropped in the case where the guest is creating a 4k HPTE
and the host page size is 64k. By getting the low-order bits from
hva rather than gpa we miss out on bits 12 - 15 in this case, since
hva is at page granularity. This puts the missing bits back in.

Akira-san has been reporting rare deadlocks of his machine when running
xfstests test 269 on ext4 filesystem. The problem turned out to be in
ext4_da_reserve_metadata() and ext4_da_reserve_space() which called
ext4_should_retry_alloc() while holding i_data_sem. Since
ext4_should_retry_alloc() can force a transaction commit, this is a
lock ordering violation and leads to deadlocks.
Fix the problem by just removing the retry loops. These functions should
just report ENOSPC to the caller (e.g. ext4_da_write_begin()) and that
function must take care of retrying after dropping all necessary locks.

imx_drm_crtc_register() doesn't clean up the CRTC upon failure, which
leaves the CRTC attached to the DRM device. Also, it does setup after
attaching the CRTC to the DRM device.
Fix this by reordering the function such that we do the setup before
drm_crtc_init(): this fixes both issues.

Enable lock claims that it is serializing tve_enable/disable calls.
However, DRM already serialises mode sets with a mutex, which prevents
encoder/connector functions being called concurrently. Secondly,
holding a spinlock while calling clk_prepare_enable() is wrong; it
will cause a might_sleep() warning should that debugging be enabled.
So, let's just get rid of the enable_lock.

When using dt resources retrieval (interrupts and reg properties) there is
no predefined order for these resources in the platform dev resources
table.
Retrieve resources using platform_get_resource and platform_get_irq

The neighbour code sends up an RTM_NEWNEIGH netlink notification if
the NUD state of a neighbour cache entry is changed by a timer (e.g.
from REACHABLE to STALE), even if the lladdr of the entry has not
changed.
But an administrative change to the the NUD state of a neighbour cache
entry that does not change the lladdr (e.g. via "ip -4 neigh change
... nud ...") does not trigger a netlink notification. This means
that netlink listeners will not hear about administrative NUD state
changes such as from a resolved state to PERMANENT.
This patch changes the neighbor code to generate an RTM_NEWNEIGH
message when the NUD state of an entry is changed administratively.

At some point, Measurement Computing / ComputerBoards redesigned the
PCI-DIO48H to use a PLX PCI interface chip instead of an AMCC chip.
This meant they had to put their hardware registers in the PCI BAR 2
region instead of PCI BAR 1. Unfortunately, they kept the same PCI
device ID for the new design. This means the driver recognizes the
newer cards, but doesn't work (and is likely to screw up the local
configuration registers of the PLX chip) because it's using the wrong
region.
Since the PCI subvendor and subdevice IDs were both zero on the old
design, but are the same as the vendor and device on the new design, we
can tell the old design and new design apart easily enough. Split the
existing entry for the PCI-DIO48H in `pci_8255_boards[]` into two new
entries, referenced by different entries in the PCI device ID table
`pci_8255_pci_table[]`. Use the same board name for both entries.

* Fix for a bug in the new cm36651 driver where it told the IIO driver it
was providing a decimal part, but then didn't. Now it correctly tells the
IIO core that it is only providing an integer value. This prevents random
incorrect values being output on a sysfs read.
* 3 fixes where drivers were miss specifying the endianness of their channels
as output through the buffer interface. These were discovered whilst
removing the terrible IIO_ST macro once and for all. The result is that
userspace may be informed that the buffer elements are being output as
little endian (on little endian platforms) when infact they are big endian.
Thus userspace will handle them incorrectly. This incorrect buffer
element specification is provided as sysfs attributes under
iio:deviceN/scan_elements.

A single channel in this driver was using the IIO_ST macro.
This does not provide a parameter for setting the endianness of
the channel. Thus this channel will have been reported as whatever
is the native endianness of the cpu rather than big endian. This
means it would be incorrect on little endian platforms.

This driver sets the shift value equal to IIO_BE (or 1) rather than setting
that to 0 and specificying the endianness. This means the channel type is
missreported as
[be|le]:u16/16>>1 where the be|le is dependent on the cpu native endianness,
rather than
be:u16/16>>0 resulting in any userspace code using this information, miss
converting the channel and generating thoroughly trashed data.

* Fix endianness in nft_reject, the NFTA_REJECT_TYPE netlink attributes
was not converted to network byte order as needed by all nfnetlink
subsystems, from Eric Leblond.
* Restrict SYNPROXY target to INPUT and FORWARD chains, this avoid a
possible crash due to misconfigurations, from Patrick McHardy.

This is similar to the set_peek_off patch where calling bind while the
socket is stuck in unix_dgram_recvmsg() will block and cause a hung task
spew after a while.
This is also the last place that did a straightforward mutex_lock(), so
there shouldn't be any more of these patches.
