block: don't decrement nr_phys_segments for physically contigous segments
Currently ll_merge_requests_fn, unlike all other merge functions,
reduces nr_phys_segments by one if the last segment of the previous,
and the first segment of the next segement are contigous. While this
seems like a nice solution to avoid building smaller than possible
requests it causes a mismatch between the segments actually present
in the request and those iterated over by the bvec iterators, including
__rq_for_each_bio. This can for example mistrigger the single segment
optimization in the nvme-pci driver, and might lead to mismatching
nr_phys_segments number when recalculating the number of request
when inserting a cloned request.
We could possibly work around this by making the bvec iterators take
the front and back segment size into account, but that would require
moving them from the bio to the bio_iter and spreading this mess
over all users of bvecs. Or we could simply remove this optimization
under the assumption that most users already build good enough bvecs,
and that the bio merge patch never cared about this optimization
either. The latter is what this patch does.

sbitmap: fix improper use of smp_mb__before_atomic()
This barrier only applies to the read-modify-write operations; in
particular, it does not apply to the atomic_set() primitive.

linux-kselftest-5.2-rc1-2
This kselftest second update for Linux 5.2-rc1 consists of Kselftest framework fixes from Shuah Khan - kselftest framework bpf build/test workflow regression fix - Fix to kselftest install to use default install path - Fix to kselftest KBUILD_OUTPUT builds to not clutter main KBUILD_OUTPUT directory with selftest objects - .gitignore fixes from Kelsey Skunberg - rseq selftests updates from Mathieu Desnoyers and Martin Schwidefsky: They change the per-architecture pre-abort signatures to ensure those are valid trap instructions. The way exit points are presented to debuggers is enhanced, ensuring all exit points are present, so debuggers don't have to disassemble rseq critical section to properly skip over them. Discussions with the glibc community is reaching a consensus of exposing a __rseq_handled symbol from glibc to coexist with rseq early adopters. Update the rseq selftest code to expose and use this symbol. Support for compiling asm goto with clang is added with the "-no-integrated-as" compiler switch, similarly to the top level kernel Makefile. - kselftest Makefile test run output refactoring and making test output TAP13 compliant from Kees Cook: This re-factors the selftest Makefiles to extract the test running logic to be reused between "run_tests" and "emit_tests", while also fixing up the test output to be TAP version 13 compliant: - added "plan" line - fixed result line syntax - moved all test output to be "# "-prefixed as TAP "diagnostic" lines The prefixing code includes a fallback mode for limited execution environments.

Pull AFS callback promise fixes from David Howells:
"This series fixes a bunch of problems in callback promise handling,
where a callback promise indicates a promise on the part of the server
to notify the client in the event of some sort of change to a file or
volume. In the event of a break, the client has to go and refetch the
client status from the server and discard any cached permission
information as the ACL might have changed.
The problem in the current code is that changes made by other clients
aren't always noticed, primarily because the file status information
and the callback information aren't updated in the same critical
section, even if these are carried in the same reply from an RPC
operation, and so the AFS_VNODE_CB_PROMISED flag is unreliable.
Arranging for them to be done in the same critical section during
reply decoding is tricky because of the FS.InlineBulkStatus op - which
has all the statuses in the reply arriving and then all the callbacks,
so they have to be buffered. It simplifies things a lot to move the
critical section out of the decode phase and do it after the RPC
function returns.
Also new inodes (either newly fetched or newly created) aren't
properly managed against a callback break happening before we get the
local inode up and running.
Fix this by:
- There's now a combined file status and callback record (struct
afs_status_cb) to carry both plus some flags.
- Each operation wrapper function allocates sufficient afs_status_cb
records for all the vnodes it is interested in and passes them into
RPC operations to be filled in from the reply.
- The FileStatus and CallBack record decoders no longer apply the
new/revised status and callback information to the inode/vnode at
the point of decoding and instead store the information into the
record from (2).
- afs_vnode_commit_status() then revises the file status, detects
deletion and notes callback information inside of a single critical
section. It also checks the callback break counters and cancels the
callback promise if they changed during the operation.
[*] Note that "callback break counters" are counters of server
events that cancel one or more callback promises that the client
thinks it has. The client counts the events and compares the
counters before and after an operation to see if the callback
promise it thinks it just got evaporated before it got recorded
under lock.
- Volume and server callback break counters are passed into
afs_iget() allowing callback breaks concurrent with inode set up to
be detected and the callback promise thence to be cancelled.
- AFS validation checks are now done under RCU conditions using a
read lock on cb_lock. This requires vnode->cb_interest to be made
RCU safe.
- If the checks in (6) fail, the callback breaker is then called
under write lock on the cb_lock - but only if the callback break
counter didn't change from the value read before the checks were
made.
- Results from FS.InlineBulkStatus that correspond to inodes we
currently have in memory are now used to update those inodes'
status and callback information rather than being discarded. This
requires those inodes to be looked up before the RPC op is made and
all their callback break values saved.
To aid in this, the following changes have also been made:
- Don't pass the vnode into the reply delivery functions or the
decoders. The vnode shouldn't be altered anywhere in those paths.
The only exception, for the moment, is for the call done hook for
file lock ops that wants access to both the vnode and the call -
this can be fixed at a later time.
- Get rid of the call->reply[] void* array and replace it with named
and typed members. This avoids confusion since different ops were
mapping different reply[] members to different things.
- Fix an order-1 kmalloc allocation in afs_do_lookup() and replace it
with kvcalloc().
- Always get the reply time. Since callback, lock and fileserver
record expiry times are calculated for several RPCs, make this
mandatory.
- Call afs_pages_written_back() from the operation wrapper rather
than from the delivery function.
- Don't store the version and type from a callback promise in a reply
as the information in them is of very limited use"

"This fixes a set of miscellaneous issues in the afs filesystem,
including:
- leak of keys on file close.
- broken error handling in xattr functions.
- missing locking when updating VL server list.
- volume location server DNS lookup whereby preloaded cells may not
ever get a lookup and regular DNS lookups to maintain server lists
consume power unnecessarily.
- incorrect error propagation and handling in the fileserver
iteration code causes operations to sometimes apparently succeed.
- interruption of server record check/update side op during
fileserver iteration causes uninterruptible main operations to fail
unexpectedly.
- callback promise expiry time miscalculation.
- over invalidation of the callback promise on directories.
- double locking on callback break waking up file locking waiters.
- double increment of the vnode callback break counter.
Note that it makes some changes outside of the afs code, including:
- an extra parameter to dns_query() to allow the dns_resolver key
just accessed to be immediately invalidated. AFS is caching the
results itself, so the key can be discarded.
- an interruptible version of wait_var_event().
- an rxrpc function to allow the maximum lifespan to be set on a
call.

slab: remove /proc/slab_allocators
It turned out that DEBUG_SLAB_LEAK is still broken even after recent
recue efforts that when there is a large number of objects like
kmemleak_object which is normal on a debug kernel,
# grep kmemleak /proc/slabinfo
kmemleak_object 2243606 3436210 ...
reading /proc/slab_allocators could easily loop forever while processing
the kmemleak_object cache and any additional freeing or allocating
objects will trigger a reprocessing. To make a situation worse,
soft-lockups could easily happen in this sitatuion which will call
printk() to allocate more kmemleak objects to guarantee an infinite
loop.
Also, since it seems no one had noticed when it was totally broken
more than 2-year ago - see the commit

afs: Fix application of the results of a inline bulk status fetch
Fix afs_do_lookup() such that when it does an inline bulk status fetch op,
it will update inodes that are already extant (something that afs_iget()
doesn't do) and to cache permits for each inode created (thereby avoiding a
follow up FS.FetchStatus call to determine this).
Extant inodes need looking up in advance so that their cb_break counters
before and after the operation can be compared. To this end, the inode
pointers are cached so that they don't need looking up again after the op.

asm-generic: kill <asm/segment.h> and improve nommu generic uaccess helpers
Christoph Hellwig writes:
This is a series doing two somewhat interwinded things. It improves
the asm-generic nommu uaccess helper to optionally be entirely generic
and not require any arch helpers for the actual uaccess. For the
generic uaccess.h to actually be generically useful I also had to kill
off the mess we made of <asm/segment.h>, which really shouldn't exist

signal: unconditionally leave the frozen state in ptrace_stop()
Alex Xu reported a regression in strace, caused by the introduction of
the cgroup v2 freezer. The regression can be reproduced by stracing
the following simple program:
#include <unistd.h>
int main() {
write(1, "a", 1);
return 0;
}
An attempt to run strace ./a.out leads to the infinite loop:
[ pre-main omitted ]
write(1, "a", 1) = ? ERESTARTSYS (To be restarted if SA_RESTART is set)
write(1, "a", 1) = ? ERESTARTSYS (To be restarted if SA_RESTART is set)
write(1, "a", 1) = ? ERESTARTSYS (To be restarted if SA_RESTART is set)
write(1, "a", 1) = ? ERESTARTSYS (To be restarted if SA_RESTART is set)
write(1, "a", 1) = ? ERESTARTSYS (To be restarted if SA_RESTART is set)
write(1, "a", 1) = ? ERESTARTSYS (To be restarted if SA_RESTART is set)
[ repeats forever ]
The problem occurs because the traced task leaves ptrace_stop()
(and the signal handling loop) with the frozen bit set. So let's
call cgroup_leave_frozen(true) unconditionally after sleeping
in ptrace_stop().
With this patch applied, strace works as expected:
[ pre-main omitted ]
write(1, "a", 1) = 1
exit_group(0) = ?
+++ exited with 0 +++

ARM: SoC platform updates
SoC updates, mostly refactorings and cleanups of old legacy platforms.
Major themes this release:
- Conversion of ixp4xx to a modern platform (drivers, DT, bindings)
- Moving some of the ep93xx headers around to get it closer to multiplatform enabled.
- Cleanups of Davinci
This tag also contains a few patches that were queued up as fixes before
5.1 but I didn't get sent in before release.

afs: Fix double inc of vnode->cb_break
When __afs_break_callback() clears the CB_PROMISED flag, it increments
vnode->cb_break to trigger a future refetch of the status and callback -
however it also calls afs_clear_permits(), which also increments
vnode->cb_break.
Fix this by removing the increment from afs_clear_permits().
Whilst we're at it, fix the conditional call to afs_put_permits() as the
function checks to see if the argument is NULL, so the check is redundant.

afs: Fix application of status and callback to be under same lock
When applying the status and callback in the response of an operation,
apply them in the same critical section so that there's no race between
checking the callback state and checking status-dependent state (such as
the data version).
Fix this by:
(1) Allocating a joint {status,callback} record (afs_status_cb) before
calling the RPC function for each vnode for which the RPC reply
contains a status or a status plus a callback. A flag is set in the
record to indicate if a callback was actually received.
(2) These records are passed into the RPC functions to be filled in. The
afs_decode_status() and yfs_decode_status() functions are removed and
the cb_lock is no longer taken.
(3) xdr_decode_AFSFetchStatus() and xdr_decode_YFSFetchStatus() no longer
update the vnode.
(4) xdr_decode_AFSCallBack() and xdr_decode_YFSCallBack() no longer update
the vnode.
(5) vnodes, expected data-version numbers and callback break counters
(cb_break) no longer need to be passed to the reply delivery
functions.
Note that, for the moment, the file locking functions still need
access to both the call and the vnode at the same time.
(6) afs_vnode_commit_status() is now given the cb_break value and the
expected data_version and the task of applying the status and the
callback to the vnode are now done here.
This is done under a single taking of vnode->cb_lock.
(7) afs_pages_written_back() is now called by afs_store_data() rather than
by the reply delivery function.
afs_pages_written_back() has been moved to before the call point and
is now given the first and last page numbers rather than a pointer to
the call.
(8) The indicator from YFS.RemoveFile2 as to whether the target file
actually got removed (status.abort_code == VNOVNODE) rather than
merely dropping a link is now checked in afs_unlink rather than in
xdr_decode_YFSFetchStatus().
Supplementary fixes:
(*) afs_cache_permit() now gets the caller_access mask from the
afs_status_cb object rather than picking it out of the vnode's status
record. afs_fetch_status() returns caller_access through its argument
list for this purpose also.
(*) afs_inode_init_from_status() now uses a write lock on cb_lock rather
than a read lock and now sets the callback inside the same critical
section.

afs: Fix lock-wait/callback-break double locking
__afs_break_callback() holds vnode->lock around its call of
afs_lock_may_be_available() - which also takes that lock.
Fix this by not taking the lock in __afs_break_callback().
Also, there's no point checking the granted_locks and pending_locks queues;
it's sufficient to check lock_state, so move that check out of
afs_lock_may_be_available() into __afs_break_callback() to replace the
queue checks.
