Pull tty/serial fixes from Greg KH:
"Here are some small tty/serial driver fixes for 7.3-rc6. Nothing major
here, just lots of small fixes for reported issues, some of them very
long-standing:
- tty hangup fixes that have been there since the BKL days and kept
tripping people up over time.
- vt selection bugfix
- other vt bugfixes (memory leaks and screen update fixes)
- n_gsm bugfix
- qcom-geni serial driver bugfix
- 8250 serial driver bugfixes
- other tiny serial driver fixes
All of these have been in linux-next, the last few only a few days but
testing here seems solid (this pull request was generated on that
tree)"

Pull io_uring fixes from Jens Axboe:
- Fix a task_work add use-after-free with SQPOLL.
The sqpoll thread could pop and complete the last request while
io_req_normal_work_add() was still looking at them after the mpscq
push.
Use the same approach as DEFER_TASKRUN to protect from that, holding
an RCU read lock across the add, and have exit wait for an RCU grace
period for SQPOLL rings as well.
- CQE32 ring fixes: correct the free entry check for 32b CQEs, zero the
big_cqe for aux CQEs, and only post the dummy skip CQE on CQE_MIXED
rings
- Mark the source filter table as COW when cloning bpf filters, so
registering another filter on the source doesn't modify the shared
table in place
- Initialize the task context before running the BPF loop
- Requeue zcrx multishot receives stopped by a local resource
- End a TX_TIMESTAMP multishot cmd when the CQ is full (lollipopkit)

Avoid a compilation error so that they're not used before being
declared.
