Add some selftests for signature checking when FIPS mode is enabled. These
need to be done before we start actually using the signature checking for
things and must panic the kernel upon failure.
Note that the tests must not check the blacklist lest this provide a way to
prevent a kernel from booting by installing a hash of a test key in the
appropriate UEFI table.

Move load_certificate_list(), which loads a series of binary X.509
certificates from a blob and inserts them as keys into a keyring, to be
with the asymmetric keys code that it drives.
This makes it easier to add FIPS selftest code in which we need to load up
a private keyring for the tests to use.

commit 979934da9e7a ("[PATCH] mips: update IRQ handling for vr41xx") added
a function irq_dispatch, and it'll increase irq_err_count when the get_irq
callback returns a negative value, but increase irq_err_count in get_irq
was not removed.
And also, modpost complains once gpio-vr41xx drivers become modules.
ERROR: modpost: "irq_err_count" [drivers/gpio/gpio-vr41xx.ko] undefined!
So it would be a good idea to remove repetitive increase irq_err_count in
get_irq callback.

When a VBD is not fully created and then closed, the kernel can have a
NULL pointer dereference:

info->rq and info->gd are only set in blkfront_connect(), which is
called for state 4 (XenbusStateConnected). Guard against using NULL
variables in blkfront_closing() to avoid the issue.
The rest of blkfront_closing looks okay. If info->nr_rings is 0, then
for_each_rinfo won't do anything.
blkfront_remove also needs to check for non-NULL pointers before
cleaning up the gendisk and request queue.

Intel SoC PMIC is a generic name for all PMICs that are used
on Intel platforms. In particular, INTEL_SOC_PMIC kernel configuration
option refers to Crystal Cove PMIC, which has never been a part
of any Intel Broxton hardware. Drop wrong dependency from Kconfig.
Note, the correct dependency is satisfied via ACPI PMIC OpRegion driver,
which the Type-C depends on.

poll->events and not change after. However, currently io_uring resets it
on each __io_poll_execute() for no clear reason. There is also a place

It's been reported that the recent fix for skipping the
component-binding with D-GPU caused a regression on some systems; it
resulted in the completely missing component binding with i915 GPU.
The problem was the use of pci_get_class() function. It matches with
the full PCI class bits, while we want to match only partially the PCI
base class bits. So, when a system has an i915 graphics device with
the PCI class 0380, it won't hit because we're looking for only the
PCI class 0300.
This patch fixes i915_gfx_present() to look up each PCI device and
match with PCI base class explicitly instead of pci_get_class().

In a report for a separate bug (which has already been fixed by commit
5f0b5f4d50fa "usb: gadget: fix race when gadget driver register via
ioctl") in the raw-gadget driver, the syzbot console log included
error messages caused by attempted registration of a new driver with
the same name as an existing driver:
> kobject_add_internal failed for raw-gadget with -EEXIST, don't try to register things with the same name in the same directory.
> UDC core: USB Raw Gadget: driver registration failed: -17
> misc raw-gadget: fail, usb_gadget_register_driver returned -17
These errors arise because raw_gadget.c registers a separate UDC
driver for each of the UDC instances it creates, but these drivers all
have the same name: "raw-gadget". Until recently this wasn't a
problem, but when the "gadget" bus was added and UDC drivers were
registered on this bus, it became possible for name conflicts to cause
the registrations to fail. The reason is simply that the bus code in
the driver core uses the driver name as a sysfs directory name (e.g.,
/sys/bus/gadget/drivers/raw-gadget/), and you can't create two
directories with the same pathname.
To fix this problem, the driver names used by raw-gadget are made
distinct by appending a unique ID number: "raw-gadget.N", with a
different value of N for each driver instance. And to avoid the
proliferation of error handling code in the raw_ioctl_init() routine,
the error return paths are refactored into the common pattern (goto
statements leading to cleanup code at the end of the routine).

Eric reports skb_under_panic when using dup/fwd via bond+egress hook.
Before pushing mac header, we should make sure that we're called from
ingress to put back what was pulled earlier.
In egress case, the MAC header is already there; we should leave skb
alone.
While at it be more careful here: skb might have been altered and
headroom reduced, so add a skb_cow() before so that headroom is
increased if necessary.
nf_do_netdev_egress() assumes skb ownership (it normally ends with
a call to dev_queue_xmit), so we must free the packet on error.

If a read races with an invalidation followed by another read, it is
possible for a folio to be replaced with a higher-order folio. If that
happens, we'll see a sibling entry for the new folio in the next iteration
of the loop. This manifests as a NULL pointer dereference while holding
the RCU read lock.
Handle this by simply returning. The next call will find the new folio
and handle it correctly. The other ways of handling this rare race are
more complex and it's just not worth it.

We had an off-by-one error which meant that we never marked the first page
in a read as accessed. This was visible as a slowdown when re-reading
a file as pages were being evicted from cache too soon. In reviewing
this code, we noticed a second bug where a multi-page folio would be
marked as accessed multiple times when doing reads that were less than
the size of the folio.
Abstract the comparison of whether two file positions are in the same
folio into a new function, fixing both of these bugs.

This reverts commit 73867c8709b5 ("drm/i915/display: Remove check for
low voltage sku for max dp source rate"), which, on an i7-11850H iGPU
with a Thinkpad X1 Extreme Gen 4, attached to a LG LP160UQ1-SPB1
embedded panel, causes wild flickering glitching technicolor
pyrotechnics on resumption from suspend. The display shows strobing
colors in an utter disaster explosion of pantone, as though bombs were
dropped on the leprechauns at the base of the rainbow.
Rebooting the machine fixes the issue, presumably because the display is
initialized by firmware rather than by i915. Otherwise, the GPU appears
to work fine.
Bisection traced it back to this commit, which makes sense given the
issues.
Note: This re-opens, and puts back to the drawing board,
https://gitlab.freedesktop.org/drm/intel/-/issues/5272 which was fixed
by the regressing commit.

There are some functions that were missed by commit d77e74561368 ("regmap:
Add bulk read/write callbacks into regmap_config") when support to define
bulk read/write callbacks in regmap_config was introduced.
The regmap_bulk_write() and regmap_noinc_write() functions weren't changed
to use the added map->write instead of the map->bus->write handler.
Also, the regmap_can_raw_write() was not modified to take map->write into
account. So will only return true if a bus with a .write callback is set.

Before adding support to define bulk read/write callbacks in regmap_config
by the commit d77e74561368 ("regmap: Add bulk read/write callbacks into
regmap_config"), the regmap_noinc_read() function returned an errno early
a map->bus->read callback wasn't set.
But that commit dropped the check and now a call to _regmap_raw_read() is
attempted even when bulk read operations are not supported. That function
checks for map->read anyways but there's no point to continue if the read
can't succeed.
Also is a fragile assumption to make so is better to make it fail earlier.

Support for drivers to define bulk read/write callbacks in regmap_config
was introduced by the commit d77e74561368 ("regmap: Add bulk read/write
callbacks into regmap_config"), but this commit wrongly dropped a check
in regmap_bulk_read() to determine whether bulk reads can be done or not.
Before that commit, it was checked if map->bus was set. Now has to check
if a map->read callback has been set.

Currently the Conexant codec driver sets up the beep NID after calling
snd_hda_gen_parse_auto_config(). It turned out that this results in
the insufficient setup for the beep control, as the generic parser
handles the fake path in snd_hda_gen_parse_auto_config() only if the
beep_nid is set up beforehand.
For dealing with the beep widget properly, call cx_auto_parse_beep()
before snd_hda_gen_parse_auto_config() call.

After setting the sock ktls, update ctx->sk_proto to sock->sk_prot by
tls_update(), so now ctx->sk_proto->close is tls_sk_proto_close(). When
close the sock, tls_sk_proto_close() is called for sock->sk_prot->close

occurred. That will trigger the following bug.

Commit 8ff978b8b222 ("ipv4/raw: support binding to nonlocal addresses")
introduces support for binding to nonlocal addresses, as well as some
basic test coverage for some of the related cases.
Commit b4a028c4d031 ("ipv4: ping: fix bind address validity check")
fixes a regression which incorrectly removed some checks for bind
address validation. In addition, it introduces regression tests for
those specific checks. However, those regression tests are defective, in
that they perform the tests using an incorrect combination of bind
flags. As a result, those tests fail when they should succeed.
This commit introduces additional regression tests for nonlocal binding
and fixes the defective regression tests. It also introduces new
set_sysctl calls for the ipv4_bind test group, as to perform the ICMP
binding tests it is necessary to allow ICMP socket creation by setting
the net.ipv4.ping_group_range knob.

The recent report for a crash on Haswell machines implied that the
x86-specific (rather hackish) implementation for write-cache memory
buffer allocation in ALSA core is buggy with the recent kernel in some
corner cases. This patch drops the x86-specific implementation and
uses the standard dma_alloc_wc() & co generically for avoiding the bug
and also for simplification.
