net: qrtr: resend HELLO on MHI resume
Since the MHI HELLO exchange was relocated, it is sent only at device
registration. During a suspend-resume cycle, the firmware in WiFi
cards such as WCN7850 indefinitely waits for another HELLO,
triggering:
ath12k_wifi7_pci 0004:01:00.0: timeout while waiting for restart complete
ath12k_wifi7_pci 0004:01:00.0: failed to resume core: -110
Fix this by triggering the handshake from resume_early in the MHI
transport.
Validated on Qualcomm X1E-801800 on Lenovo Slim 7x across 10
suspend-resume cycles.
Fixes: 544d85de4dc2 ("net: qrtr: Send HELLO message on endpoint register")

i2c: qcom-geni: release DMA channels on probe error
geni_i2c_init() grabs exclusive GPI tx/rx DMA channels when the serial
engine runs in GPI mode. If i2c_add_adapter() subsequently fails, probe
returns without releasing the channels, because the remove callback is
not invoked after a failed probe.
The adapter-registration failure path used to release the channels via
its err_dma label; that release was dropped when the probe tail was
restructured into geni_i2c_init().
Release the channels on the adapter-registration failure path, mirroring
geni_i2c_remove().

i2c: qcom-cci: fix device_node refcount leak in cci_probe()/cci_remove()
The of_node_put() matching of_node_get() runs after i2c_del_adapter(),
whose trailing memset() zeroes adap->dev and thus adap->dev.of_node,
making the put a no-op and leaking the node on every adapter removal
and error cleanup.
Use a devm action: the pointer is captured at registration, out of
reach of that memset(), and devres runs the put once on probe failure
and detach, replacing the three manual of_node_put() calls. The
setup loop uses the scoped iterator form so the child node is released
automatically if devm_add_action_or_reset() fails mid-loop.

posix-cpu-timers: Prevent freeing a timer which is queued on the expiry list
Kijo analyzed another race in the POSIX CPU timer code:
Commit bf635681c906 converted cpu_timer::firing from a tristate value to a
boolean. This lost the distinction between "not owned by the firing list"
and "still owned, but delivery was canceled". The resulting race is:
expiry handler timer_settime() timer_delete()
-------------- --------------- --------------
collect timer onto
private firing list
firing = true
observes firing = true
firing = false
return TIMER_RETRY

x86/build/64: Prevent native builds from generating EGPR use
Omar reports that CONFIG_X86_NATIVE_CPU=y allows builds to opportunistically
emit instructions using %r16-%r31 (EGPRs) when the build host supports APX
since the commit:
ea1dcca1de12 ("x86/kbuild/64: Add the CONFIG_X86_NATIVE_CPU option to locally optimize the kernel with '-march=native'")
But the kernel is not yet prepared to use new registers internally. For
example, there is no context-switch support for general in-kernel use.
Explicitly disable EGPR use when building with -march=native.
For C, since GCC 14 and Clang 18, both compilers support suppressing EGPR
use with -mno-apx-features=egpr, whose availability can be detected via
cc-option.
For Rust, pass features=-apxf through the generated JSON to avoid
unstable-feature warnings, see
