wifi: mt76: mt7921: refactor regd update to fix recursive mutex deadlock
Split mt7921_mcu_regd_update() into two functions to prevent recursive
mutex acquisition. Introduce __mt7921_mcu_regd_update() as the internal
implementation that assumes the mutex is already held by the caller,
while mt7921_mcu_regd_update() remains as the external interface that
handles mutex acquisition and release.
This fixes a deadlock issue when mt7921_regd_set_6ghz_power_type() is
called with the device mutex already held. Without this change, calling
mt7921_mcu_regd_update() would attempt to acquire the same mutex again,
causing a recursive lock deadlock.
The __mt7921_mcu_regd_update() function can be safely called when the
caller has already acquired the device mutex, avoiding the deadlock
while maintaining proper synchronization for regulatory domain updates.

Revert "i2c: designware: defer probe if child GpioInt controllers are not bound"
This reverts commit 0a4bb2abc3e56d7be6e69b050c88ba52c87e22bf.
This was reported to break the touchpad on at least some Thinkpads, and
while the revert has hit the i2c tree, it hasn't hit mine. So I'm
reverting it directly just to have this resolved for the imminent 7.2
release.

drbd: don't leak the shared secret to unprivileged netlink dumps
The conversion to explicit netlink serialization dropped the
exclude_sensitive parameter from net_conf_to_skb(), so each caller has
to sanitize by hand. Two dump paths were missed:
drbd_nl_get_connections_dumpit() and the volume-less connection branch
of get_one_status(). Neither op carries GENL_ADMIN_PERM, so any
unprivileged local user could read the CRAM-HMAC secret.
Add a net_conf_to_skb_sanitized() wrapper and route all three callers
through it.

- mask all privileged bits when restoring the supervisor register
from sigreturn"
* tag 'for-linus' of https://github.com/openrisc/linux:
openrisc: signal: do not restore privileged SR bits on sigreturn
openrisc: signal: do not restore privileged SR bits on sigreturn
restore_sigcontext() copies the whole supervision register (SR) from the
signal frame and only clears SPR_SR_SM before the value is reloaded into
the hardware SR (through ESR and l.rfe) on the return to user space. All
other SR bits are left under user control.
An unprivileged task can thus return from a signal handler through a
crafted sigframe that clears SPR_SR_DME. With the data MMU disabled the
CPU performs no translation or protection on data accesses, so the task
gains read and write access to arbitrary physical memory, a local
privilege escalation. SPR_SR_IME, SPR_SR_SUMRA, SPR_SR_LEE, SPR_SR_EPH
and the cache-enable bits are exposed the same way. The ptrace GPR regset
already refuses any change to SR for exactly this reason.
Restore only the arithmetic flag bits (F, CY, OV) from the signal frame
and take every privileged control bit from the SR the kernel saved on
signal entry.

- Don't warn when a mount is completed from another user namespace.
fsopen() records the caller's user namespace in fc->user_ns and
hands back an ordinary file descriptor. The task that calls
fsconfig(FSCONFIG_CMD_CREATE) doesn't have to be the one that
created the context, and mount_capable() lets it through as long
as the caller has CAP_SYS_ADMIN over fc->user_ns, which anyone in
an ancestor namespace does. So fc->user_ns != current_user_ns()
is something an unprivileged user can arrange.
Both overlayfs and binfmt_misc WARN_ON() that. Overlayfs already
has the same check as a plain error return in ovl_parse_param().
Drop the WARN_ON() and just refuse. Add selftests for both cases.

erofs: fix EROFS_FS_ZIP_LZMA_DEFAULT_MAX_STREAMS on some UP platforms
CONFIG_NR_CPUS doesn't define on some UP platforms (e.g. arm), so this
can cause make oldconfig to loop indefinitely when CONFIG_SMP=n:
$ make ARCH=arm allmodconfig
$ sed -i "/CONFIG_SMP=y/d" .config
$ sed -i "/CONFIG_EROFS_FS_ZIP_LZMA_DEFAULT_MAX_STREAMS.*/d" .config
EROFS LZMA default maximum decompression streams (EROFS_FS_ZIP_LZMA_DEFAULT_MAX_STREAMS) [0] (NEW)
EROFS LZMA default maximum decompression streams (EROFS_FS_ZIP_LZMA_DEFAULT_MAX_STREAMS) [0] (NEW)
...
Let's guard NR_CPUS with SMP instead of using a hardcoded arbitrary CPU
uplimit here, similar to commit a3344078101c ("mm: make SPLIT_PTE_PTLOCKS
depend on SMP").
The initial report from SJ Park was for m68k [1] (m68k is the only arch
without NR_CPUS in Kconfig), and that got fixed in commit 1fd495ef09ee
