Replace the PLL146_CONF() macro and its associated CPG_SAMPLL_CLK{1,2}(n)
helpers with a single CPG_SAM_PLL_CONF(stby) macro that takes the PLL
standby register offset directly.
This removes the implicit coupling between PLL index n and register layout
and eliminates the now-redundant GET_REG_SAMPLL_CLK2() macro. The RZ/V2M
PLL4 definition is also updated to use the new macro with its explicit
standby offset (0x100), removing the local PLL4_CONF define.
No functional changes.

Document the ZT trace bus and ZTR trace clocks on R-Mobile APE6. These
clocks supply the coresight tracing modules, PTM, TPIU, ETB and
replicator. Without these clocks, coresight tracing can not be
operated. While this does change the ABI, it does so by extending the
existing clock-output-names, therefore if old software is used with new
DT, the coresight tracing parts will likely fail to probe, otherwise if
new software is used with an old DT, there is no impact.

x86_energy_perf_policy accesses the SoC Slider via standard

Machines that support SoC Slider largely use it instead of EPP,
which may continue to exist in a diminished role, or vanish entirely.

When processor_thermal_soc_slider is loaded, its slider
and offset modparams are visible. Check that the driver
actually registered the profile named "SoC Slider" before
reading or writing these modparams.
n.b. This utility allows writing the Slider and Offset modparams
even if the driver policy is not "balanced". Currently the
processor_thermal_soc_slider consults those modparams
only in "balanced" mode.

On Raspberry Pi 3B, the VEC clock is used by the VideoCore firmware
display driver, which remains active until the vc4 driver loads and
sends NOTIFY_DISPLAY_DONE. If this clock is disabled during boot, a bus
lockup happens and the firmware becomes unresponsive, causing a complete
system lockup.
Mark the VEC clock with CLK_IGNORE_UNUSED so it survives the unused
clock disablement and remains available until the vc4 driver takes over
display management.

- Fix accounting of persistent ring buffer rewind
On boot up, the head page is moved back to the earliest point of
the saved ring buffer. This is because the ring buffer being read by
user space on a crash may not save the part it read. Rewinding the head
page back to the earliest saved position helps keep those events from
being lost.
The number of events is also read during boot up and displayed in the
stats file in the tracefs directory. It's also used for other accounting
as well. On boot up, the "reader page" is accounted for but a rewind may
put it back into the buffer and then the reader page may be accounted
for again.
Save off the original reader page and skip accounting it when scanning
the pages in the ring buffer.

Merge tag 'io_uring-7.1-20260424' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux
Pull io_uring fixes from Jens Axboe:
- Fix for a NOMMU bug with io_uring, where NOMMU doesn't grab page refs
at mmap time. NOMMU also has entirely broken FOLL_PIN support, yet
here we are
- A few fixes covering minor issues introduced in this merge window
- data race annotation to shut up KCSAN for when io-wq limits are
applied
- A nospec addition for direct descriptor file updating. Rest of the
direct descriptor path already had this, but for some reason the
update did not. Now they are all the same
- Various minor defensive changes that claude identified and suggested
terrible fixes for, turned into actually useful cleanups:
- Use kvfree() for the imu cache. These can come from kmalloc or
vmalloc depending on size, but the in-cache ones are capped
where it's always kmalloc based. Change to kvfree() in the
cleanup path, making future changes unlikely to mess that up
- Negative kbuf consumption lengths. Can't happen right now, but
cqe->res is used directly, which if other codes changes could
then be an error value
- Fix for an issue with the futex code, where partial wakes on a
vectored fuxes would potentially wake the same futex twice, rather
than move on to the next one. This could confuse an application as it
would've expected the next futex to have been woken
- Fix for a bug with ring resizing, where SQEs or CQEs might not have
been copied correctly if large SQEs or CQEs are used in the ring.
Application side issue, where SQEs or CQEs might have been lost
during resize
- Fix for a bug where EPOLL_URING_WAKE might have been lost, causing a
multishot poll to not be terminated when it's nested, like it should
have been
- Fix for an issue with signed comparison of poll references for the
slow path
- Fix for a user struct UAF in the zcrx code
- Two minor zcrx cleanups
