This macro assigns mtk_mux_gate_clr_set_upd_ops, whose

being lost.
The number of events is also read during boot up and displayed in the

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

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

Pull RISC-V updates from Paul Walmsley:
"There is one significant change outside arch/riscv in this pull
request: the addition of a set of KUnit tests for strlen(), strnlen(),
and strrchr().
Otherwise, the most notable changes are to add some RISC-V-specific
string function implementations, to remove XIP kernel support, to add
hardware error exception handling, and to optimize our runtime
unaligned access speed testing.
A few comments on the motivation for removing XIP support. It's been
broken in the RISC-V kernel for months. The code is not easy to
maintain. Furthermore, for XIP support to truly be useful for RISC-V,
we think that compile-time feature switches would need to be added for
many of the RISC-V ISA features and microarchitectural properties that
are currently implemented with runtime patching. No one has stepped
forward to take responsibility for that work, so many of us think it's
best to remove it until clear use cases and champions emerge.
Summary:
- Add Kunit correctness testing and microbenchmarks for strlen(),
strnlen(), and strrchr()
