First set of new device support, features and cleanups for IIO in the 5.11 cycle
Usual mixed bag of new drivers / device support + cleanups etc with the
addition of a fairly big set of yaml conversions.
Txt to yaml format conversions.
In some cases dropped separate binding and moved to trivial devices (drop).

This is a very small binding. It might make sense at some stage
to just roll it into the parent mfd. For now, converted as is.
The main advantage of this document is the identification of the
channel index values when this is used as a provider of ADC channels
to consumers.

Rationale for #164:
data is declared as u32, and it is read and then converted by means of
be32_to_cpu(). Said function expects a __be32 but data is u32, therefore
there's a type missmatch here.
Rationale for #239:
Is the dual of #164. This time data going to be written so it
needs to be converted from cpu to __be32, but writel() expects u32 and the
output of cpu_to_be32 returns a __be32.

afs: Fix speculative status fetch going out of order wrt to modifications
When doing a lookup in a directory, the afs filesystem uses a bulk
status fetch to speculatively retrieve the statuses of up to 48 other
vnodes found in the same directory and it will then either update extant
inodes or create new ones - effectively doing 'lookup ahead'.
To avoid the possibility of deadlocking itself, however, the filesystem
doesn't lock all of those inodes; rather just the directory inode is
locked (by the VFS).
When the operation completes, afs_inode_init_from_status() or
afs_apply_status() is called, depending on whether the inode already
exists, to commit the new status.
A case exists, however, where the speculative status fetch operation may
straddle a modification operation on one of those vnodes. What can then
happen is that the speculative bulk status RPC retrieves the old status,
and whilst that is happening, the modification happens - which returns
an updated status, then the modification status is committed, then we
attempt to commit the speculative status.
This results in something like the following being seen in dmesg:
kAFS: vnode modified {100058:861} 8->9 YFS.InlineBulkStatus
showing that for vnode 861 on volume 100058, we saw YFS.InlineBulkStatus
say that the vnode had data version 8 when we'd already recorded version
9 due to a local modification. This was causing the cache to be
invalidated for that vnode when it shouldn't have been. If it happens
on a data file, this might lead to local changes being lost.
Fix this by ignoring speculative status updates if the data version
doesn't match the expected value.
Note that it is possible to get a DV regression if a volume gets
restored from a backup - but we should get a callback break in such a
case that should trigger a recheck anyway. It might be worth checking
the volume creation time in the volsync info and, if a change is
observed in that (as would happen on a restore), invalidate all caches
associated with the volume.

Use kstrtoull() instead of simple_strtoll() to convert a string got from

mm/userfaultfd: do not access vma->vm_mm after calling handle_userfault()
Alexander reported a syzkaller / KASAN finding on s390, see below for
complete output.
In do_huge_pmd_anonymous_page(), the pre-allocated pagetable will be
freed in some cases. In the case of userfaultfd_missing(), this will
happen after calling handle_userfault(), which might have released the
mmap_lock. Therefore, the following pte_free(vma->vm_mm, pgtable) will
access an unstable vma->vm_mm, which could have been freed or re-used
already.
For all architectures other than s390 this will go w/o any negative
impact, because pte_free() simply frees the page and ignores the
passed-in mm. The implementation for SPARC32 would also access
mm->page_table_lock for pte_free(), but there is no THP support in
SPARC32, so the buggy code path will not be used there.
For s390, the mm->context.pgtable_list is being used to maintain the 2K
pagetable fragments, and operating on an already freed or even re-used
mm could result in various more or less subtle bugs due to list /
pagetable corruption.
Fix this by calling pte_free() before handle_userfault(), similar to how
it is already done in __do_huge_pmd_anonymous_page() for the WRITE /
non-huge_zero_page case.
Commit
6b251fc96cf2c ("userfaultfd: call handle_userfault() for
userfaultfd_missing() faults") actually introduced both, the
do_huge_pmd_anonymous_page() and also __do_huge_pmd_anonymous_page()
changes wrt to calling handle_userfault(), but only in the latter case
it put the pte_free() before calling handle_userfault().

mm: fix phys_to_target_node() and memory_add_physaddr_to_nid() exports
The core-mm has a default __weak implementation of phys_to_target_node()
to mirror the weak definition of memory_add_physaddr_to_nid(). That
symbol is exported for modules. However, while the export in
mm/memory_hotplug.c exported the symbol in the configuration cases of:
CONFIG_NUMA_KEEP_MEMINFO=y
CONFIG_MEMORY_HOTPLUG=y
...and:
CONFIG_NUMA_KEEP_MEMINFO=n
CONFIG_MEMORY_HOTPLUG=y
...it failed to export the symbol in the case of:
CONFIG_NUMA_KEEP_MEMINFO=y
CONFIG_MEMORY_HOTPLUG=n
Not only is that broken, but Christoph points out that the kernel should
not be exporting any __weak symbol, which means that
memory_add_physaddr_to_nid() example that phys_to_target_node() copied
is broken too.
Rework the definition of phys_to_target_node() and
memory_add_physaddr_to_nid() to not require weak symbols. Move to the
common arch override design-pattern of an asm header defining a symbol
to replace the default implementation.
The only common header that all memory_add_physaddr_to_nid() producing
architectures implement is asm/sparsemem.h. In fact, powerpc already
defines its memory_add_physaddr_to_nid() helper in sparsemem.h.
Double-down on that observation and define phys_to_target_node() where
necessary in asm/sparsemem.h. An alternate consideration that was
discarded was to put this override in asm/numa.h, but that entangles
with the definition of MAX_NUMNODES relative to the inclusion of
linux/nodemask.h, and requires powerpc to grow a new header.
The dependency on NUMA_KEEP_MEMINFO for DEV_DAX_HMEM_DEVICES is invalid
now that the symbol is properly exported / stubbed in all combinations

This is a somewhat unusual device, in that it effectively does
spi offload. That means that it doesn't act as a full SPI
master, but supports some functionality. As such it supports
a subset of specific SPI ADCs. There is potential for a future
clash in bindings, but as these are simple devices hopefully that
will not occur.
One addition to this from testing it against existing dts files
was to add a resets property.
This is specified in arch/arm/boot/dts/r8a7791.dtsi
If it's the dtsi that is wrong and not the binding doc, then
we can fix that instead.

It seems that when this was tested the happy case was more tested. A few of
the userspace apps rely on this returning negative error codes in case an
ioctl() is not available.
When running multiple ioctl() handlers or when calling an ioctl() that
doesn't exist, IIO_IOCTL_UNHANDLED is returned. In that case -EINVAL should
be returned.

iio: triggered-buffer: add {devm_}iio_triggered_buffer_setup_ext variants
This change adds a parameter to the {devm_}iio_triggered_buffer_setup()
functions to assign the extra sysfs buffer attributes that are typically
assigned via iio_buffer_set_attrs().
The functions also get renamed to iio_triggered_buffer_setup_ext() &
devm_iio_triggered_buffer_setup_ext().
For backwards compatibility the old {devm_}iio_triggered_buffer_setup()
functions are now macros wrap the new (renamed) functions with NULL for the
buffer attrs.
The aim is to remove iio_buffer_set_attrs(), so in the
iio_triggered_buffer_setup_ext() function the attributes are assigned
directly to 'buffer->attrs'.
When adding multiple IIO buffers per IIO device, it can be pretty
cumbersome to first allocate a set of buffers, then to dig them out of IIO
to assign extra attributes (with iio_buffer_set_attrs()).
Naturally, the best way would be to provide them at allocation time, which
is what this change does.
At this moment, buffers allocated with {devm_}iio_triggered_buffer_setup()
are the only ones in mainline IIO to call iio_buffer_set_attrs().

xfs: revert "xfs: fix rmap key and record comparison functions"
This reverts commit
6ff646b2ceb0eec916101877f38da0b73e3a5b7f.
Your maintainer committed a major braino in the rmap code by adding the
attr fork, bmbt, and unwritten extent usage bits into rmap record key
comparisons. While XFS uses the usage bits *in the rmap records* for
cross-referencing metadata in xfs_scrub and xfs_repair, it only needs
the owner and offset information to distinguish between reverse mappings
of the same physical extent into the data fork of a file at multiple
offsets. The other bits are not important for key comparisons for index
lookups, and never have been.
Eric Sandeen reports that this causes regressions in generic/299, so
undo this patch before it does more damage.

Pull networking fixes from Jakub Kicinski:
"Networking fixes for 5.10-rc5, including fixes from the WiFi
(mac80211), can and bpf (including the strncpy_from_user fix).
Current release - regressions:
- mac80211: fix memory leak of filtered powersave frames
- mac80211: free sta in sta_info_insert_finish() on errors to avoid
sleeping in atomic context
- netlabel: fix an uninitialized variable warning added in -rc4
Previous release - regressions:
- vsock: forward all packets to the host when no H2G is registered,
un-breaking AWS Nitro Enclaves
- net: Exempt multicast addresses from five-second neighbor lifetime
requirement, decreasing the chances neighbor tables fill up
- net/tls: fix corrupted data in recvmsg
- qed: fix ILT configuration of SRC block
- can: m_can: process interrupt only when not runtime suspended
Previous release - always broken:
- page_frag: Recover from memory pressure by not recycling pages
allocating from the reserves
- strncpy_from_user: Mask out bytes after NUL terminator
- ip_tunnels: Set tunnel option flag only when tunnel metadata is
present, always setting it confuses Open vSwitch
- bpf, sockmap:
- Fix partial copy_page_to_iter so progress can still be made
- Fix socket memory accounting and obeying SO_RCVBUF
- net: Have netpoll bring-up DSA management interface
- net: bridge: add missing counters to ndo_get_stats64 callback
- tcp: brr: only postpone PROBE_RTT if RTT is < current min_rtt
- enetc: Workaround MDIO register access HW bug
- net/ncsi: move netlink family registration to a subsystem init,
instead of tying it to driver probe
- net: ftgmac100: unregister NC-SI when removing driver to avoid
crash
- lan743x:
- prevent interrupt storm on open
- fix freeing skbs in the wrong context
- net/mlx5e: Fix socket refcount leak on kTLS RX resync
- net: dsa: mv88e6xxx: Avoid VLAN database corruption on 6097
- fix 21 unset return codes and other mistakes on error paths, mostly
detected by the Hulk Robot"

ext4: drop fast_commit from /proc/mounts
The options in /proc/mounts must be valid mount options --- and
fast_commit is not a mount option. Otherwise, command sequences like
this will fail:
# mount /dev/vdc /vdc
# mkdir -p /vdc/phoronix_test_suite /pts
# mount --bind /vdc/phoronix_test_suite /pts
# mount -o remount,nodioread_nolock /pts
mount: /pts: mount point not mounted or bad option.
