pipe: remove 'waiting_writers' merging logic
This code is ancient, and goes back to when we only had a single page for the pipe buffers. The exact history is hidden in the mists of time (ie "before git", and in fact predates the BK repository too). At that long-ago point in time, it actually helped to try to merge big back-and-forth pipe reads and writes, and not limit pipe reads to the single pipe buffer in length just because that was all we had at a time. However, since then we've expanded the pipe buffers to multiple pages, and this logic really doesn't seem to make sense. And a lot of it is somewhat questionable (ie "hmm, the user asked for a non-blocking read, but we see that there's a writer pending, so let's wait anyway to get the extra data that the writer will have"). But more importantly, it makes the "go to sleep" logic much less obvious, and considering the wakeup issues we've had, I want to make for less of those kinds of things.

pipe: fix and clarify pipe read wakeup logic
This is the read side version of the previous commit: it simplifies the logic to only wake up waiting writers when necessary, and makes sure to use a synchronous wakeup. This time not so much for GNU make jobserver reasons (that pipe never fills up), but simply to get the writer going quickly again. A bit less verbose commentary this time, if only because I assume that the write side commentary isn't going to be ignored if you touch this code.

pipe: fix and clarify pipe write wakeup logic
The pipe rework ends up having been extra painful, partly becaused of actual bugs with ordering and caching of the pipe state, but also because of subtle performance issues. In particular, the pipe rework caused the kernel build to inexplicably slow down. The reason turns out to be that the GNU make jobserver (which limits the parallelism of the build) uses a pipe to implement a "token" system: a parallel submake will read a character from the pipe to get the job token before starting a new job, and will write a character back to the pipe when it is done. The overall job limit is thus easily controlled by just writing the appropriate number of initial token characters into the pipe. But to work well, that really means that the old behavior of write wakeups being synchronous (WF_SYNC) is very important - when the pipe writer wakes up a reader, we want the reader to actually get scheduled immediately. Otherwise you lose the parallelism of the build. The pipe rework lost that synchronous wakeup on write, and we had clearly all forgotten the reasons and rules for it. This rewrites the pipe write wakeup logic to do the required Wsync wakeups, but also clarifies the logic and avoids extraneous wakeups. It also ends up addign a number of comments about what oit does and why, so that we hopefully don't end up forgetting about this next time we change this code.

pipe: fix poll/select race introduced by the pipe rework
The kernel wait queues have a basic rule to them: you add yourself to
the wait-queue first, and then you check the things that you're going to
wait on. That avoids the races with the event you're waiting for.
The same goes for poll/select logic: the "poll_wait()" goes first, and
then you check the things you're polling for.
Of course, if you use locking, the ordering doesn't matter since the
lock will serialize with anything that changes the state you're looking
at. That's not the case here, though.
So move the poll_wait() first in pipe_poll(), before you start looking
at the pipe state.

ARM: SoC fixes
A set of fixes that we've merged late, but for the most part that have
been sitting in -next for a while through platform maintainer trees.
+ Fixes to suspend/resume on Tegra, caused by the added features
this merge window
+ Cleanups and minor fixes to TI additions this merge window
+ Tee fixes queued up late before the merge window, included here.
+ A handful of other fixlets
There's also a refresh of the shareed config files (multi_v* on 32-bit,
and defconfig on 64-bit), to avoid conflicts when we get new
contributions.

Pull more block and io_uring updates from Jens Axboe:
"I wasn't expecting this to be so big, and if I was, I would have used
separate branches for this. Going forward I'll be doing separate
branches for the current tree, just like for the next kernel version
tree. In any case, this contains:
- Series from Christoph that fixes an inherent race condition with
zoned devices and revalidation.
- null_blk zone size fix (Damien)
- Fix for a regression in this merge window that caused busy spins by
sending empty disk uevents (Eric)
- Fix for a regression in this merge window for bfq stats (Hou)
- Fix for io_uring creds allocation failure handling (me)
- io_uring -ERESTARTSYS send/recvmsg fix (me)
- Series that fixes the need for applications to retain state across
async request punts for io_uring. This one is a bit larger than I
would have hoped, but I think it's important we get this fixed for
5.5.
- connect(2) improvement for io_uring, handling EINPROGRESS instead
of having applications needing to poll for it (me)
- Have io_uring use a hash for poll requests instead of an rbtree.
This turned out to work much better in practice, so I think we
should make the switch now. For some workloads, even with a fair
amount of cancellations, the insertion sort is just too expensive.
(me)
- Various little io_uring fixes (me, Jackie, Pavel, LimingWu)
- Fix for brd unaligned IO, and a warning for the future (Ming)
- Fix for a bio integrity data leak (Justin)
- bvec_iter_advance() improvement (Pavel)
- Xen blkback page unmap fix (SeongJae)
The major items in here are all well tested, and on the liburing side
we continue to add regression and feature test cases. We're up to 50
topic cases now, each with anywhere from 1 to more than 10 cases in
each"

Pull vfs d_inode/d_flags memory ordering fixes from Al Viro:
"Fallout from tree-wide audit for ->d_inode/->d_flags barriers use.
Basically, the problem is that negative pinned dentries require
careful treatment - unless ->d_lock is locked or parent is held at
least shared, another thread can make them positive right under us.
Most of the uses turned out to be safe - the main surprises as far as
filesystems are concerned were
- race in dget_parent() fastpath, that might end up with the caller
observing the returned dentry _negative_, due to insufficient
barriers. It is positive in memory, but we could end up seeing the
wrong value of ->d_inode in CPU cache. Fixed.
- manual checks that result of lookup_one_len_unlocked() is positive
(and rejection of negatives). Again, insufficient barriers (we
might end up with inconsistent observed values of ->d_inode and
->d_flags). Fixed by switching to a new primitive that does the
checks itself and returns ERR_PTR(-ENOENT) instead of a negative
dentry. That way we get rid of boilerplate converting negatives
into ERR_PTR(-ENOENT) in the callers and have a single place to
deal with the barrier-related mess - inside fs/namei.c rather than
in every caller out there.
The guts of pathname resolution *do* need to be careful - the race
found by Ritesh is real, as well as several similar races.
Fortunately, it turns out that we can take care of that with fairly
local changes in there.
The tree-wide audit had not been fun, and I hate the idea of repeating
it. I think the right approach would be to annotate the places where
we are _not_ guaranteed ->d_inode/->d_flags stability and have sparse
catch regressions. But I'm still not sure what would be the least
invasive way of doing that and it's clearly the next cycle fodder"
* 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
fs/namei.c: fix missing barriers when checking positivity
fix dget_parent() fastpath race

arm64: KVM: Invoke compute_layout() before alternatives are applied
compute_layout() is invoked as part of an alternative fixup under stop_machine(). This function invokes get_random_long() which acquires a sleeping lock on -RT which can not be acquired in this context. Rename compute_layout() to kvm_compute_layout() and invoke it before stop_machine() applies the alternatives. Add a __init prefix to kvm_compute_layout() because the caller has it, too (and so the code can be discarded after boot).

arm64: Validate tagged addresses in access_ok() called from kernel threads
__range_ok(), invoked from access_ok(), clears the tag of the user
address only if CONFIG_ARM64_TAGGED_ADDR_ABI is enabled and the thread
opted in to the relaxed ABI. The latter sets the TIF_TAGGED_ADDR thread
flag. In the case of asynchronous I/O (e.g. io_submit()), the
access_ok() may be called from a kernel thread. Since kernel threads
don't have TIF_TAGGED_ADDR set, access_ok() will fail for valid tagged
user addresses. Example from the ffs_user_copy_worker() thread:
use_mm(io_data->mm);
ret = ffs_copy_to_iter(io_data->buf, ret, &io_data->data);
unuse_mm(io_data->mm);
Relax the __range_ok() check to always untag the user address if called
in the context of a kernel thread. The user pointers would have already
been checked via aio_setup_rw() -> import_{single_range,iovec}() at the
time of the asynchronous I/O request.

Merge branch 'next.autofs' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull autofs updates from Al Viro: "autofs misuses checks for ->d_subdirs emptiness; the cursors are in the same lists, resulting in false negatives. It's not needed anyway, since autofs maintains counter in struct autofs_info, containing 0 for removed ones, 1 for live symlinks and 1 + number of children for live directories, which is precisely what we need for those checks. This series switches to use of that counter and untangles the crap around its uses (it needs not be atomic and there's a bunch of completely pointless "defensive" checks). This fell out of dcache_readdir work; the main point is to get rid of ->d_subdirs abuses in there. I've more followup cleanups, but I hadn't run those by Ian yet, so they can go next cycle" * 'next.autofs' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: autofs: don't bother with atomics for ino->count autofs_dir_rmdir(): check ino->count for deciding whether it's empty... autofs: get rid of pointless checks around ->count handling autofs_clear_leaf_automount_flags(): use ino->count instead of ->d_subdirs |

Merge branch 'pipe-rework' (patches from David Howells)
Merge two fixes for the pipe rework from David Howells:
"Here are a couple of patches to fix bugs syzbot found in the pipe
changes:
- An assertion check will sometimes trip when polling a pipe because
the ring size and indices used are approximate and may be being
changed simultaneously.
An equivalent approximate calculation was done previously, but
without the assertion check, so I've just dropped the check. To
make it accurate, the pipe mutex would need to be taken or the spin
lock could be used - but usage of the spinlock would need to be
rolled out into splice, iov_iter and other places for that.
- The index mask and the max_usage values cannot be cached across
pipe_wait() as F_SETPIPE_SZ could have been called during the wait.
This can cause pipe_write() to break"
* pipe-rework:
pipe: Fix missing mask update after pipe_wait()
pipe: Remove assertion from pipe_poll()

pipe: Fix missing mask update after pipe_wait()
Fix pipe_write() to not cache the ring index mask and max_usage as their
values are invalidated by calling pipe_wait() because the latter
function drops the pipe lock, thereby allowing F_SETPIPE_SZ change them.
Without this, pipe_write() may subsequently miscalculate the array
indices and pipe fullness, leading to an oops like the following:
BUG: KASAN: slab-out-of-bounds in pipe_write+0xc25/0xe10 fs/pipe.c:481

This is not a problem for pipe_read() as the mask is recalculated on
each pass of the loop, after pipe_wait() has been called.

pipe: Remove assertion from pipe_poll()
An assertion check was added to pipe_poll() to make sure that the ring
occupancy isn't seen to overflow the ring size. However, since no locks
are held when the three values are read, it is possible for F_SETPIPE_SZ
to intervene and muck up the calculation, thereby causing the oops.
Fix this by simply removing the assertion and accepting that the
calculation might be approximate.
Note that the previous code also had a similar issue, though there was
no assertion check, since the occupancy counter and the ring size were
not read with a lock held, so it's possible that the poll check might
have malfunctioned then too.
Also wake up all the waiters so that they can reissue their checks if
there was a competing read or write.

Modules updates for v5.5
Summary of modules changes for the 5.5 merge window:
- Refactor include/linux/export.h and remove code duplication between
EXPORT_SYMBOL and EXPORT_SYMBOL_NS to make it more readable. The most
notable change is that no namespace is represented by an empty string ""

"Summary of modules changes for the 5.5 merge window:
- Refactor include/linux/export.h and remove code duplication between
EXPORT_SYMBOL and EXPORT_SYMBOL_NS to make it more readable.
The most notable change is that no namespace is represented by an
empty string "" rather than NULL.
- Fix a module load/unload race where waiter(s) trying to load the

- A larger set of work on Tegra 2/3 around memory controller and
regulator features, some fuse cleanups, etc..
- MMP platform drivers, in particular for USB PHY, and other smaller
additions.
- Samsung Exynos 5422 driver for DMC (dynamic memory configuration),
and ASV (adaptive voltage), allowing the platform to run at more
optimal operating points.
- Misc refactorings and support for RZ/G2N and R8A774B1 from Renesas
- Clock/reset control driver for TI/OMAP
- Meson-A1 reset controller support
- Qualcomm sdm845 and sda845 SoC IDs for socinfo
