printk: queue wake_up_klogd irq_work only if per-CPU areas are ready
printk_deferred(), similarly to printk_safe/printk_nmi, does not
immediately attempt to print a new message on the consoles, avoiding
calls into non-reentrant kernel paths, e.g. scheduler or timekeeping,
which potentially can deadlock the system.
Those printk() flavors, instead, rely on per-CPU flush irq_work to print
messages from safer contexts. For same reasons (recursive scheduler or
timekeeping calls) printk() uses per-CPU irq_work in order to wake up
user space syslog/kmsg readers.
However, only printk_safe/printk_nmi do make sure that per-CPU areas
have been initialised and that it's safe to modify per-CPU irq_work.
This means that, for instance, should printk_deferred() be invoked "too
early", that is before per-CPU areas are initialised, printk_deferred()
will perform illegal per-CPU access.

Bug fixes for main IPMI driver, kcs updates
A couple of bug fixes for the main IPMI driver, one functional and two annotations. The kcs driver has some significant updates that have been pending for a while, but I forgot to include in next until a week ago. But this code is only used by the people who are sending it to me, really, so it's not a big deal. I did want it to sit in next for at least a week, and it did result in a fix. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE/Q1c5nzg9ZpmiCaGYfOMkJGb/4EFAl6Qc3AACgkQYfOMkJGb /4EOxhAAtEkoudrXYDDd39B+wVjW0JZ59jBKtTiosLrK+mE0hyq5rh+lJLqmtKmy uF69HLqtSGl7ZgpFdzeT8M1fRt4uTTh7BuOkkc2r/18/a+YVJOUFnUpB4BLg06O8 Wr1dMeya6KukM+S3clezCx7jwkwu3V+E8lUKxkQg6zIHRw+DevNUL2Ec6MpZI4SJ KIjmyp62ASIuME0YeEXnx3wrFzOJIR+01liu4R/4OcDBR2p6fb/TqPFwY4HCq9Fy pV7riuqXLTGKYk9vnmeHMYZGXT8I55FvkQIB73QWRSpcIyLLcht0wQ04dRQFF/jA j4ZLfGNTvHgnJQiLmRjPIGGbmiUPx76fWghAC87QtT07HksYEvnsbbxuZ/lZTGdc NmV7X25HHr/YM4wEffALiaOHXzWXkuxkN0ptzrulbyYOE3631jwAMhcyzucvPvTO 7wU5qshQHTLqQLwyvChdThsKNukmaqOdBH9/vONsXFvgcLy14ZNyR3oPObQUpD6n CtKbteXSuIA2cjYBj1oCgZ/3lwmYd/DVqGhqGYCnNElnSekF14p312lE+NiXYxnZ 7BIqKBn51asdeWdeJNFOk0qZog6YquwCM7m16kSukzehPaUsovuJkDpVGKpEhYEg 2M4aiiDr/gWpoXJBg6xMM2j//268z6Oe3C6ZX1XPD1jzZ8Gv/Y0= =vV/F -----END PGP SIGNATURE----- Merge tag 'for-linus-5.7-1' of git://github.com/cminyard/linux-ipmi Pull IPMI updates from Corey Minyard: "Bug fixes for main IPMI driver, kcs updates A couple of bug fixes for the main IPMI driver, one functional and two annotations.

(More) new code for 5.7:
- Validate the realtime geometry in the superblock when mounting
- Refactor a bunch of tricky flag handling in the log code
- Flush the CIL more judiciously so that we don't wait until there are
millions of log items consuming a lot of memory.
- Throttle transaction commits to prevent the xfs frontend from flooding
the CIL with too many log items.
- Account metadata buffers correctly for memory reclaim.
- Mark slabs properly for memory reclaim. These should help reclaim run
more effectively when XFS is using a lot of memory.
- Don't write a garbage log record at unmount time if we're trying to
trigger summary counter recalculation at next mount.
- Don't block the AIL on locked dquot/inode buffers; instead trigger its
backoff mechanism to give the lock holder a chance to finish up.
- Ratelimit writeback flushing when buffered writes encounter ENOSPC.
- Other minor cleanups.
- Make reflink a synchronous operation when the fs is mounted with wsync
or sync, which means that now we force the log to disk to record the
changes.

Pull more xfs updates from Darrick Wong:
"As promised last week, this batch changes how xfs interacts with
memory reclaim; how the log batches and throttles log items; how hard
writes near ENOSPC will try to squeeze more space out of the
filesystem; and hopefully fix the last of the umount hangs after a
catastrophic failure.

io_uring: punt final io_ring_ctx wait-and-free to workqueue
We can't reliably wait in io_ring_ctx_wait_and_kill(), since the task_works list isn't ordered (in fact it's LIFO ordered). We could either fix this with a separate task_works list for io_uring work, or just punt the wait-and-free to async context. This ensures that task_work that comes in while we're shutting down is processed correctly. If we don't go async, we could have work past the fput() work for the ring that depends on work that won't be executed until after we're done with the wait-and-free. But as this operation is blocking, it'll never get a chance to run. This was reproduced with hundreds of thousands of sockets running memcached, haven't been able to reproduce this synthetically.

RISC-V Patches for the 5.7 Merge Window, Part 1
This tag contains the patches I'd like to target for 5.7. It has a handful of
new features:
* Partial support for the Kendryte K210. There are still a few outstanding
issues that I have patches for, but I don't actually have a board to test
them so they're not included yet.
* SBI v0.2 support.
* Fixes to support for building with LLVM-based toolchains. The resulting
images are known not to boot yet.
This builds and boots for me. There is one merge conflict, it's just a Kconfig
merge issue. I can publish a resolved branch if you'd like.
I don't anticipate a part two, but I'll probably have something early in the
RCs to finish up the K210 support.

The problem is that because wait_pidfd.lock is taken under the tasklist
lock. It must always be taken with irqs disabled as tasklist_lock can be
taken from interrupt context and if wait_pidfd.lock was already taken this
would create a lock order inversion.
Oleg suggested just disabling irqs where I have added extra calls to
wait_pidfd.lock. That should be safe and I think the code will eventually
do that. It was rightly pointed out by Christian that sharing the
wait_pidfd.lock was a premature optimization.
It is also true that my pre-merge window testing was insufficient. So
remove the premature optimization and give struct pid a dedicated lock of
it's own for struct pid things. I have verified that lockdep sees all 3
paths where we take the new pid->lock and lockdep does not complain.
It is my current day dream that one day pid->lock can be used to guard the
task lists as well and then the tasklist_lock won't need to be held to
deliver signals. That will require taking pid->lock with irqs disabled.

io_uring: fix fs cleanup on cqe overflow
If completion queue overflow occurs, __io_cqring_fill_event() will update req->cflags, which is in a union with req->work and happens to be aliased to req->work.fs. Following io_free_req() -> io_req_work_drop_env() may get a bunch of different problems (miscount fs->users, segfault, etc) on cleaning @fs.

drm/bridge: analogix_dp: Split bind() into probe() and real bind()
Analogix_dp driver acquires all its resources in the ->bind() callback,
what is a bit against the component driver based approach, where the
driver initialization is split into a probe(), where all resources are
gathered, and a bind(), where all objects are created and a compound
driver is initialized.
Extract all the resource related operations to analogix_dp_probe() and
analogix_dp_remove(), then call them before/after registration of the
device components from the main Exynos DP and Rockchip DP drivers. Also
move the plat_data initialization to the probe() to make it available for
the analogix_dp_probe() function.
This fixes the multiple calls to the bind() of the DRM compound driver
when the DP PHY driver is not yet loaded/probed:

The main items are:
- support for asynchronous create and unlink (Jeff Layton). Creates
and unlinks are satisfied locally, without waiting for a reply from
the MDS, provided the client has been granted appropriate caps (new
in v15.y.z ("Octopus") release). This can be a big help for metadata
heavy workloads such as tar and rsync. Opt-in with the new nowsync
mount option.
- multiple blk-mq queues for rbd (Hannes Reinecke and myself). When
the driver was converted to blk-mq, we settled on a single blk-mq
queue because of a global lock in libceph and some other technical
debt. These have since been addressed, so allocate a queue per CPU
to enhance parallelism.
- don't hold onto caps that aren't actually needed (Zheng Yan). This
has been our long-standing behavior, but it causes issues with some
active/standby applications (synchronous I/O, stalls if the standby
goes down, etc).
- .snap directory timestamps consistent with ceph-fuse (Luis Henriques)

- Save x86 numa information to allow for node-id lookups for reserved
memory ranges, deploy that capability for the e820-pmem driver.
- Pick up some miscellaneous minor fixes, that missed v5.6-final,

Pull libnvdimm and dax updates from Dan Williams:
"There were multiple touches outside of drivers/nvdimm/ this round to
add cross arch compatibility to the devm_memremap_pages() interface,
enhance numa information for persistent memory ranges, and add a

arm64: armv8_deprecated: Fix undef_hook mask for thumb setend
For thumb instructions, call_undef_hook() in traps.c first reads a u16,
and if the u16 indicates a T32 instruction (u16 >= 0xe800), a second
u16 is read, which then makes up the the lower half-word of a T32
instruction. For T16 instructions, the second u16 is not read,
which makes the resulting u32 opcode always have the upper half set to
0.
However, having the upper half of instr_mask in the undef_hook set to 0
masks out the upper half of all thumb instructions - both T16 and T32.
This results in trapped T32 instructions with the lower half-word equal
to the T16 encoding of setend (b650) being matched, even though the upper
half-word is not 0000 and thus indicates a T32 opcode.
An example of such a T32 instruction is eaa0b650, which should raise a
SIGILL since T32 instructions with an eaa prefix are unallocated as per
Arm ARM, but instead works as a SETEND because the second half-word is set
to b650.
This patch fixes the issue by extending instr_mask to include the
upper u32 half, which will still match T16 instructions where the upper
