After commit 6511882cdd ("mptcp: allocate fwd memory separately
on the rx and tx path") __lock_sock() can be static again.
Make sure __lock_sock() is not inlined, so that lock_sock_nested()
no longer needs a stack canary.
Add a noinline attribute on lock_sock_nested() so that calls
to lock_sock() from net/core/sock.c are not inlined,
none of them are fast path to deserve that:
- sockopt_lock_sock()
- sock_set_reuseport()
- sock_set_reuseaddr()
- sock_set_mark()
- sock_set_keepalive()
- sock_no_linger()
- sock_bindtoindex()

With kmalloc_obj() performing implicit size calculations, the embedded
size_mul() calls, while marked inline, were not always being inlined.
I noticed a couple places where allocations were making a call out for
things that would otherwise be compile-time calculated. Force the
compilers to always inline these calculations.

Fix a bug where kunit_run_irq_test() could hang if the system is too
slow. This was noticed with the crypto library tests in certain VMs.
Specifically, if kunit_irq_test_timer_func() and the associated hrtimer
code took over 5us to run, then the CPU would spend all its time
executing that code in hardirq context. As a result, the task executing
kunit_run_irq_test() never had a chance to run, exit the loop, and
cancel the timer.
To fix it, make kunit_irq_test_timer_func() increase the timer interval
when the other contexts aren't having a chance to run.

Wa_15010599737 was a workaround originally proposed (and ultimately

even considered for any other platforms.
The specific bit this workaround was setting is documented as "This bit
should be set to 1 for the DX9 API and 0 for all other APIs" which means
that it should almost always be left at the default value of 0 on Linux.
The register itself is directly accessible from userspace, so in the
special cases where it might be relevant (e.g., Wine/Proton running
Windows DX9 apps), the userspace drivers already have the ability to
change the setting without involvement of the kernel.

dvb_dvr_open() calls dvb_ringbuffer_init() when a new reader opens the
DVR device. dvb_ringbuffer_init() calls init_waitqueue_head(), which
reinitializes the waitqueue list head to empty.
Since dmxdev->dvr_buffer.queue is a shared waitqueue (all opens of the
same DVR device share it), this orphans any existing waitqueue entries
from io_uring poll or epoll, leaving them with stale prev/next pointers
while the list head is reset to {self, self}.
The waitqueue and spinlock in dvr_buffer are already properly
initialized once in dvb_dmxdev_init(). The open path only needs to
reset the buffer data pointer, size, and read/write positions.
Replace the dvb_ringbuffer_init() call in dvb_dvr_open() with direct
assignment of data/size and a call to dvb_ringbuffer_reset(), which
properly resets pread, pwrite, and error with correct memory ordering
without touching the waitqueue or spinlock.

The new imx93w.dtsi is based on imx93.dtsi and adds the pieces required
for the internal connection between i.MX93 and IW610 inside the SiP.
This includes USDHC3 which is used as the host interface to the IW610
and the required GPIO settings(e.g. WL_RST, WL_REG_ON, etc.).
These nodes reflect internal SiP wiring and are not board specific, so
they are placed in a dedicated imx93w.dtsi file that can be reused by

The i.MX93 Wireless EVK reuses most of the 11x11 EVK design. To avoid
duplication and DTS-to-DTS includes, extract the common parts into a new
imx93-11x11-evk-common.dtsi shared by both boards.
Rename imx93-11x11-evk.dts to imx93-11x11-evk-common.dtsi and include it
from imx93-11x11-evk.dts.
Only structural changes are introduced, with no intended functional
impact.

During system resume, the following errors occurred:
[ 430.638625] mmc1: error -84 writing Cache Enable bit
[ 430.643618] mmc1: error -84 doing runtime resume
For eMMC and SD, there are two tuning pass windows and the gap between
those two windows may only have one cell. If tuning step > 1, the gap may
just be skipped and host assumes those two windows as a continuous
windows. This will cause a wrong delay cell near the gap to be selected.
Set the tuning step to 1 to avoid selecting the wrong delay cell.
For SDIO, the gap is sufficiently large, so the default tuning step does
not cause this issue.
