the 5.4 cycle, to devfreq (Leonard Crestez).

Pull io_uring fixes from Jens Axboe:
- A tweak to IOSQE_IO_LINK (also marked for stable) to allow links that
don't sever if the result is < 0.
This is mostly for linked timeouts, where if we ask for a pure
timeout we always get -ETIME. This makes links useless for that case,
hence allow a case where it works.
- Five minor optimizations to fix and improve cases that regressed
since v5.4.
- An SQTHREAD locking fix.
- A sendmsg/recvmsg iov assignment fix.
- Net fix where read_iter/write_iter don't honor IOCB_NOWAIT, and
subsequently ensuring that works for io_uring.
- Fix a case where for an invalid opcode we might return -EBADF instead
of -EINVAL, if the ->fd of that sqe was set to an invalid fd value.

"A mostly mechanical treewide conversion from FIELD_SIZEOF() to
sizeof_field(). This avoids the redundancy of having 2 macros
(actually 3) doing the same thing, and consolidates on sizeof_field().
While "field" is not an accurate name, it is the common name used in

those during this coming development cycle and send the final old

Objects allocated by xen_blkif_alloc come from the 'blkif_cache' kmem
cache. This cache is destoyed when xen-blkif is unloaded so it is
necessary to wait for the deferred free routine used for such objects to
complete. This necessity was missed in commit 14855954f636 "xen-blkback:
allow module to be cleanly unloaded". This patch fixes the problem by
taking/releasing extra module references in xen_blkif_alloc/free()
respectively.

SMB2_tdis() checks if a root handle is valid in order to decide
whether it needs to close the handle or not. However if another
thread has reference for the handle, it may end up with putting
the reference twice. The extra reference that we want to put
during the tree disconnect is the reference that has a directory
lease. So, track the fact that we have a directory lease and
close the handle only in that case.

Commit 5e6669387e22 ("of/platform: Pause/resume sync state during init
and of_platform_populate()") paused/resumed sync state during init only
if Linux had parsed and populated a devicetree.
However, the check for that (of_have_populated_dt()) can change after
of_platform_default_populate_init() executes. One example of this is
when devicetree unittests are enabled. This causes an unmatched
pause/resume of sync state. To avoid this, just unconditionally
pause/resume sync state during init.

Fix device memory flows so that only once there will be no live mmaped
VA to a given allocation the matching object will be destroyed.
This prevents a potential scenario that existing VA that was mmaped by
one process might still be used post its deallocation despite that it's
owned now by other process.
The above is achieved by integrating with IB core APIs to manage
mmap/munmap. Only once the refcount will become 0 the DM object and its
underlay area will be freed.

ksys_dup() is used only at one place in the kernel, namely to duplicate
fd 0 of /dev/console to stdout and stderr. The same functionality can be

The IDE driver creates some passthru requests which never get
submitted to the block layer in such a way that blk_account_io_start()
gets called. However, the driver still calls __blk_mq_end_request() in
ide_end_rq() which will call blk_account_io_completion() which tries
to dereferences req->part which is never set. See ide_prep_sense() for
an example of where these requests come from.
To fix this, blk_account_io_completion() and blk_account_io_done()
should do nothing if req->part is not set.
The back trace of this bug is:
BUG: kernel NULL pointer dereference, address: 000002ac

In prepare_namespace(), do_mount() can be used instead of ksys_mount()
as the first and third argument are const strings in the kernel, the
second and fourth argument are passed through anyway, and the fifth
argument is NULL.
In do_mount_root(), ksys_mount() is called with the first and third
argument being already kernelspace strings, which do not need to be
copied over from userspace to kernelspace (again). The second and
fourth arguments are passed through to do_mount() anyway. The fifth
argument, while already residing in kernelspace, needs to be put into
a page of its own. Then, do_mount() can be used instead of
ksys_mount().
Once this is done, there are no in-kernel users to ksys_mount() left,
which can therefore be removed.

All three calls to ksys_mount() in initrd-related kernel code can
be switched over to do_mount():
- the first and third arguments are const strings in the kernel,
and do not need to be copied over from userspace;
- the fifth argument is NULL, and therefore no page needs to be,
copied over from userspace;
- the second and fourth argument are passed through anyway.

In devtmpfs, do_mount() can be called directly instead of complex wrapping
by ksys_mount():
- the first and third arguments are const strings in the kernel,
and do not need to be copied over from userspace;
- the fifth argument is NULL, and therefore no page needs to be
copied over from userspace;
- the second and fourth argument are passed through anyway.

Commit 5ace77e0b41a ("nios2: remove __ioremap") removed the following code,
with the argument that cacheflag is always 0 and the expression would
therefore always be false.
if (IS_MAPPABLE_UNCACHEABLE(phys_addr) &&
IS_MAPPABLE_UNCACHEABLE(last_addr) &&
!(cacheflag & _PAGE_CACHED))
return (void __iomem *)(CONFIG_NIOS2_IO_REGION_BASE + phys_addr);
This did not take the "!" in the expression into account. Result is that
nios2 images no longer boot. Restoring the removed code fixes the problem.
