Commit a5450aba73 ("ASoC: rockchip: i2s: switch BCLK to GPIO") switched
BCLK to GPIO functions when probing the i2s bus interface, but missed
adding a check for when devm_pinctrl_get() returns an error. This can lead
to the following NULL pointer dereference on a rockpro64-v2 if there are no
"pinctrl" properties in the i2s device tree node.
Check that i2s->pinctrl is valid before attempting to search for the
bclk_on and bclk_off pinctrl states.

Because of the possible failure of the allocation, data->domains might
be NULL pointer and will cause the dereference of the NULL pointer
later.
Therefore, it might be better to check it and directly return -ENOMEM
without releasing data manually if fails, because the comment of the
devm_kmalloc() says "Memory allocated with this function is
automatically freed on driver detach.".

PMP8074 is a companion PMIC for the Qualcomm IPQ8074 WiSoC-s.
It features 5 HF-SMPS and 13 LDO regulators.
HF-SMPS regulators are Buck HFS430 regulators.
L1, L2 and L3 are HT_N1200_ST subtype LDO regulators.
L4 is HT_N300_ST subtype LDO regulator.
L5 and L6 are HT_P600 subtype LDO regulators.
L7, L11, L12 and L13 are HT_P150 subtype LDO regulators.
L10 is HT_P50 subtype LDO regulator.
This commit adds support for all of the buck regulators and LDO-s except
for L10 as I dont have documentation on its output voltage range.
S3 is the CPU cluster voltage supply, S4 supplies the UBI32 NPU cores
and L11 is the SDIO/eMMC I/O voltage regulator required for high speeds.

found in PMP8074 and PMS405 PMIC-s.
Both PMP8074 and PMS405 define the programmable range as 1.704 to 1.896V
but the actual MAX output voltage depends on the exact LDO in each of

Netfilter fixes for net
The following patchset contains Netfilter fixes for net:
1) refcount_inc_not_zero() is not semantically equivalent to
atomic_int_not_zero(), from Florian Westphal. My understanding was
that refcount_*() API provides a wrapper to easier debugging of
reference count leaks, however, there are semantic differences
between these two APIs, where refcount_inc_not_zero() needs a barrier.
Reason for this subtle difference to me is unknown.
2) packet logging is not correct for ARP and IP packets, from the
ARP family and netdev/egress respectively. Use skb_network_offset()
to reach the headers accordingly.
3) set element extension length have been growing over time, replace

The error paths of gntdev_mmap() can call unmap_grant_pages() even
though not all of the pages have been successfully mapped. This will
trigger the WARN_ON()s in __unmap_grant_pages_done(). The number of
warnings can be very large; I have observed thousands of lines of
warnings in the systemd journal.
Avoid this problem by only warning on unmapping failure if the handle
being unmapped is not INVALID_GRANT_HANDLE. The handle field of any
page that was not successfully mapped will be INVALID_GRANT_HANDLE, so
this catches all cases where unmapping can legitimately fail.

When using iTXQ, the code assumes that there is only one vif queue for
broadcast packets, using the BE queue. Allowing non-BE queue marking
violates that assumption and txq->ac == skb_queue_mapping is no longer

also causes issues with the recent ATF change, resulting in an AQL

Currently, the only way x86 can get an early boot RNG seed is via EFI,
which is generally always used now for physical machines, but is very
rarely used in VMs, especially VMs that are optimized for starting
"instantaneously", such as Firecracker's MicroVM. For tiny fast booting
VMs, EFI is not something you generally need or want.
Rather, the image loader or firmware should be able to pass a single
random seed, exactly as device tree platforms do with the "rng-seed"
property. Additionally, this is something that bootloaders can append,
with their own seed file management, which is something every other
major OS ecosystem has that Linux does not (yet).
Add SETUP_RNG_SEED, similar to the other eight setup_data entries that
are parsed at boot. It also takes care to zero out the seed immediately
after using, in order to retain forward secrecy. This all takes about 7
trivial lines of code.
Then, on kexec_file_load(), a new fresh seed is generated and passed to
the next kernel, just as is done on device tree architectures when
using kexec. And, importantly, I've tested that QEMU is able to properly
pass SETUP_RNG_SEED as well, making this work for every step of the way.
This code too is pretty straight forward.
Together these measures ensure that VMs and nested kexec()'d kernels
always receive a proper boot time RNG seed at the earliest possible
stage from their parents:
- Host [already has strongly initialized RNG]
- QEMU [passes fresh seed in SETUP_RNG_SEED field]
- Linux [uses parent's seed and gathers entropy of its own]
- kexec [passes this in SETUP_RNG_SEED field]
- Linux [uses parent's seed and gathers entropy of its own]
- kexec [passes this in SETUP_RNG_SEED field]
- Linux [uses parent's seed and gathers entropy of its own]
- kexec [passes this in SETUP_RNG_SEED field]
- ...
I've verified in several scenarios that this works quite well from a
host kernel to QEMU and down inwards, mixing and matching loaders, with
every layer providing a seed to the next.

Chimera Linux notes that CONFIG_CC_HAS_SANE_STACKPROTECTOR cannot be
enabled when cross compiling an x86_64 kernel with clang, even though it
does work when natively compiling.
When building on aarch64:
$ make -sj"$(nproc)" ARCH=x86_64 LLVM=1 defconfig
$ grep STACKPROTECTOR .config
When building on x86_64:
$ make -sj"$(nproc)" ARCH=x86_64 LLVM=1 defconfig
$ grep STACKPROTECTOR .config
CONFIG_CC_HAS_SANE_STACKPROTECTOR=y
CONFIG_HAVE_STACKPROTECTOR=y
CONFIG_STACKPROTECTOR=y
CONFIG_STACKPROTECTOR_STRONG=y
When clang is invoked without a '--target' flag, code is generated for
the default target, which is usually the host (it is configurable via
cmake). As a result, the has-stack-protector scripts will generate code
for the default target but check for x86 specific segment registers,
which cannot succeed if the default target is not x86.
$(CLANG_FLAGS) contains an explicit '--target' flag so pass that
variable along to the has-stack-protector scripts so that the stack
protector can be enabled when cross compiling with clang. The 32-bit
stack protector cannot currently be enabled with clang, as it does not
support '-mstack-protector-guard-symbol', so this results in no
functional change for ARCH=i386 when cross compiling.

Fix this by removing the handling for RoCEv2 in

This is a collection of three fixes for small annoyances.
Two of these are already pending in other trees, but I really don't want
to release another -rc with these issues pending, so I picked up the
patches for these things directly. We'll end up with duplicate commits
eventually, I prefer that over having these issues pending.
The third one is just me getting rid of another BUG_ON() just because it
was reported and I dislike those things so much.
* merge 'hot-fixes' branch:
ida: don't use BUG_ON() for debugging
drm/aperture: Run fbdev removal before internal helpers
ptrace: fix clearing of JOBCTL_TRACED in ptrace_unfreeze_traced()
This is another old BUG_ON() that just shouldn't exist (see also commit
a382f8fee4: "signal handling: don't use BUG_ON() for debugging").
In fact, as Matthew Wilcox points out, this condition shouldn't really
even result in a warning, since a negative id allocation result is just
a normal allocation failure:
"I wonder if we should even warn here -- sure, the caller is trying to
free something that wasn't allocated, but we don't warn for
kfree(NULL)"
and goes on to point out how that current error check is only causing
people to unnecessarily do their own index range checking before freeing
it.
This was noted by Itay Iellin, because the bluetooth HCI socket cookie
code does *not* do that range checking, and ends up just freeing the
error case too, triggering the BUG_ON().
The HCI code requires CAP_NET_RAW, and seems to just result in an ugly
splat, but there really is no reason to BUG_ON() here, and we have
generally striven for allocation models where it's always ok to just do
free(alloc());
even if the allocation were to fail for some random reason (usually
obviously that "random" reason being some resource limit).
Fixes: 88eca0207c ("ida: simplified functions for id allocation")
