This modifier is primarily intended to be used by panvk to implement
sparse partially-resident images with better map and unmap
performance, and no worse access performance, compared to
implementing them in terms of U-interleaved.
With this modifier, the plane is divided into 64k byte 1:1 or 2:1
-sided tiles. The 64k tiles are laid out linearly. Each 64k tile
is divided into blocks of 16x16 texel blocks each, which themselves
are laid out linearly within a 64k tile. Then within each such
16x16 block, texel blocks are laid out according to U order,
similar to 16X16_BLOCK_U_INTERLEAVED.
Unlike 16X16_BLOCK_U_INTERLEAVED, the layout does not depend on
whether a format is compressed or not.
The hardware features corresponding to this modifier are available
starting with v10 (second gen Valhall.)

No changes since v2
Changes since v1:
* Rewrite the description of the modifier to be hopefully unambiguous.

The Linux 6.19 merge window added the new BLKREPORTZONESV2 ioctl, and
with it the new BLK_ZONE_REP_CACHED and BLK_ZONE_COND_ACTIVE constants.
The two constants are defined as part of enums, which makes it very
painful for userspace to discover if they are present in the installed
system headers.
Use the #define to the same name trick to make them trivially
discoverable using CPP directives.

When the AP has an advertised TID to Link Mapping (TTLM) it shall
include the element in the association response. As such, when this
element is present it needs to be used for the currently dormant links.
See Draft P802.11REVmf_D1.0 section 35.3.7.2.3 ("Negotiation of TTLM")
for the details. The flag is also not usable in case userspace wants to
specify a negotiated TTLM during association.
Note that for the link reconfiguration case, mac80211 did not use the
information. Draft P802.11REVmf_D1.0 states in section 35.3.6.4 ("Link
reconfiguration to the setup links) that we "shall operate with all the
TIDs mapped to the newly added links ..."
All this means that the flag is not needed. The implementation should
parse the information from the association response.

ext4: fix iloc.bh leak in ext4_xattr_inode_update_ref
ext4: add missing down_write_data_sem in mext_move_extent().
ext4: fix ext4_tune_sb_params padding
The padding at the end of struct ext4_tune_sb_params is architecture
specific and in particular is different between x86-32 and x86-64,
since the __u64 member only enforces struct alignment on the latter.
This shows up as a new warning when test-building the headers with
-Wpadded:
include/linux/ext4.h:144:1: error: padding struct size to alignment boundary with 4 bytes [-Werror=padded]
All members inside the structure are naturally aligned, so the only
difference here is the amount of padding at the end. Make the padding
explicit, to have a consistent sizeof(struct ext4_tune_sb_params) of
232 on all architectures and avoid adding compat ioctl handling for
EXT4_IOC_GET_TUNE_SB_PARAM/EXT4_IOC_SET_TUNE_SB_PARAM.
This is an ABI break on x86-32 but hopefully this can go into 6.18.y early
enough as a fixup so no actual users will be affected. Alternatively, the
kernel could handle the ioctl commands for both sizes (232 and 228 bytes)
on all architectures.

The `COMEDI_RANGEINFO` ioctl does not work properly for subdevice
indices above 15. Currently, the only in-tree COMEDI drivers that
support more than 16 subdevices are the "8255" driver and the
"comedi_bond" driver. Making the ioctl work for subdevice indices up to
255 is achievable. It needs minor changes to the handling of the
`COMEDI_RANGEINFO` and `COMEDI_CHANINFO` ioctls that should be mostly
harmless to user-space, apart from making them less broken. Details
follow...
The `COMEDI_RANGEINFO` ioctl command gets the list of supported ranges
(usually with units of volts or milliamps) for a COMEDI subdevice or
channel. (Only some subdevices have per-channel range tables, indicated
by the `SDF_RANGETYPE` flag in the subdevice information.) It uses a
`range_type` value and a user-space pointer, both supplied by
user-space, but the `range_type` value should match what was obtained
using the `COMEDI_CHANINFO` ioctl (if the subdevice has per-channel
range tables) or `COMEDI_SUBDINFO` ioctl (if the subdevice uses a
single range table for all channels). Bits 15 to 0 of the `range_type`
value contain the length of the range table, which is the only part that
user-space should care about (so it can use a suitably sized buffer to
fetch the range table). Bits 23 to 16 store the channel index, which is
assumed to be no more than 255 if the subdevice has per-channel range
tables, and is set to 0 if the subdevice has a single range table. For
`range_type` values produced by the `COMEDI_SUBDINFO` ioctl, bits 31 to
24 contain the subdevice index, which is assumed to be no more than 255.
But for `range_type` values produced by the `COMEDI_CHANINFO` ioctl,
bits 27 to 24 contain the subdevice index, which is assumed to be no
more than 15, and bits 31 to 28 contain the COMEDI device's minor device
number for some unknown reason lost in the mists of time. The
`COMEDI_RANGEINFO` ioctl extract the length from bits 15 to 0 of the
user-supplied `range_type` value, extracts the channel index from bits
23 to 16 (only used if the subdevice has per-channel range tables),
extracts the subdevice index from bits 27 to 24, and ignores bits 31 to
28. So for subdevice indices 16 to 255, the `COMEDI_SUBDINFO` or
`COMEDI_CHANINFO` ioctl will report a `range_type` value that doesn't
work with the `COMEDI_RANGEINFO` ioctl. It will either get the range
table for the subdevice index modulo 16, or will fail with `-EINVAL`.
To fix this, always use bits 31 to 24 of the `range_type` value to hold
the subdevice index (assumed to be no more than 255). This affects the
`COMEDI_CHANINFO` and `COMEDI_RANGEINFO` ioctls. There should not be
anything in user-space that depends on the old, broken usage, although
it may now see different values in bits 31 to 28 of the `range_type`
values reported by the `COMEDI_CHANINFO` ioctl for subdevices that have
per-channel subdevices. User-space should not be trying to decode bits
31 to 16 of the `range_type` values anyway.

Move the description of the LANDLOCK_ACCESS_FS_IOCTL_DEV access right
together with the file access rights.
This group of access rights applies to files (in this case device
files), and they can be added to file or directory inodes using
landlock_add_rule(2). The check for that works the same for all file
access rights, including LANDLOCK_ACCESS_FS_IOCTL_DEV.
Invoking ioctl(2) on directory FDs can not currently be restricted
with Landlock. Having it grouped separately in the documentation is a
remnant from earlier revisions of the LANDLOCK_ACCESS_FS_IOCTL_DEV
patch set.

"AMDGPU_GEM_DOMAIN_MMIO_REMAP" - Never activated as UAPI and it turned
out that this was to inflexible.
Allocate the MMIO_REMAP buffer object as a regular GEM BO and explicitly
move it into the fixed AMDGPU_PL_MMIO_REMAP placement at the TTM level.
This avoids relying on GEM domain bits for MMIO_REMAP, keeps the
placement purely internal, and makes the lifetime and pinning of the
global MMIO_REMAP BO explicit. The BO is pinned in TTM so it cannot be
migrated or evicted.
The corresponding free path relies on normal DRM teardown ordering,
where no further user ioctls can access the global BO once TTM teardown
begins.
v2 (Srini):
- Updated patch title.
- Drop use of AMDGPU_GEM_DOMAIN_MMIO_REMAP in amdgpu_ttm.c. The
MMIO_REMAP domain bit is removed from UAPI, so keep the MMIO_REMAP BO
allocation domain-less (bp.domain = 0) and rely on the TTM placement
(AMDGPU_PL_MMIO_REMAP) for backing/pinning.
- Keep fdinfo/mem-stats visibility for MMIO_REMAP by classifying BOs
based on bo->tbo.resource->mem_type == AMDGPU_PL_MMIO_REMAP, since the
domain bit is removed.
v3: Squash patches #1 & #3

The EM YNL specification used many acronyms, including ‘em’, ‘pd’,
‘ps’, etc. While the acronyms are short and convenient, they could be
confusing. So, let’s spell them out to be more specific. The following
changes were made in the spec. Note that the protocol name cannot exceed
GENL_NAMSIZ (16).
em -> dev-energymodel
pds -> perf-domains
pd -> perf-domain
pd-id -> perf-domain-id
pd-table -> perf-table
ps -> perf-state
get-pds -> get-perf-domains
get-pd-table -> get-perf-table
pd-created -> perf-domain-created
pd-updated -> perf-domain-updated
pd-deleted -> perf-domain-deleted
In addition. doc strings were added to the spec. based on the comments in
energy_model.h. Two flag attributes (perf-state-flags and
perf-domain-flags) were added for easily interpreting the bit flags.
Finally, the autogenerated files and em_netlink.c were updated accordingly
to reflect the name changes.

- Documentation fix: Add missing kernel-doc description for the @isnew
parameter in ilookup5_nowait() to silence Sphinx warnings
- Documentation fix: Fix kernel-doc comment for __start_dirop() - the

ext4-on-iomap work (didn't handle allocation failure properly) and
triggered lockdep complaints. Uses a flag instead to control batch

- Re-add #ifdef guards around PIDFD_GET_<ns-type>_NAMESPACE ioctls.
When a namespace type is disabled, ns->ops is NULL, causes crashes
during inode eviction when closing the fd. The ifdefs were removed in

I haven't found an NFSERR_EAGAIN in RFCs 1094, 1813, 7530, or 8881.
None of these RFCs have an NFS status code that match the numeric
value "11".
Based on the meaning of the EAGAIN errno, I presume the use of this
status in NFSD means NFS4ERR_DELAY. So replace the one usage of
nfserr_eagain, and remove it from NFSD's NFS status conversion
tables.
As far as I can tell, NFSERR_EAGAIN has existed since the pre-git
era, but was not actually used by any code until commit f4e44b3933
("NFSD: delay unmount source's export after inter-server copy
completed."), at which time it become possible for NFSD to return
a status code of 11 (which is not valid NFS protocol).
Fixes: f4e44b3933 ("NFSD: delay unmount source's export after inter-server copy completed.")

The first member of struct xattr_args is declared as
__aligned_u64 __user value;
which makes no sense whatsoever; __user is a qualifier and what that
declaration says is "all struct xattr_args instances have .value
_stored_ in user address space, no matter where the rest of the
structure happens to be".
Something like "int __user *p" stands for "value of p is a pointer
to an instance of int that happens to live in user address space"; it
says nothing about location of p itself, just as const char *p declares a
pointer to unmodifiable char rather than an unmodifiable pointer to char.
With xattr_args the intent clearly had been "the 64bit value
represents a _pointer_ to object in user address space", but __user has
nothing to do with that. All it gets us is a couple of bogus warnings
in fs/xattr.c where (userland) instance of xattr_args is copied to local
variable of that type (in kernel address space), followed by access
to its members. Since we've told sparse that args.value must somehow be
located in userland memory, we get warned that looking at that 64bit
unsigned integer (in a variable already on kernel stack) is not allowed.
Note that sparse has no way to express "this integer shall never
be cast into a pointer to be dereferenced directly" and I don't see any
way to assign a sane semantics to that. In any case, __user is not it.

Use device file descriptors and regions to represent pagemaps on
foreign or local devices.
The underlying files are type-checked at madvise time, and
references are kept on the drm_pagemap as long as there is are
madvises pointing to it.
Extend the madvise preferred_location UAPI to support the region
instance to identify the foreign placement.
v2:
- Improve UAPI documentation. (Matt Brost)
- Sanitize preferred_mem_loc.region_instance madvise. (Matt Brost)
- Clarify madvise drm_pagemap vs xe_pagemap refcounting. (Matt Brost)
- Don't allow a foreign drm_pagemap madvise without a fast
interconnect.
v3:
- Add a comment about reference-counting in xe_devmem_open() and
remove the reference-count get-and-put. (Matt Brost)

Using libc types and headers from the UAPI headers is problematic as it
introduces a dependency on a full C toolchain.
Use the fixed-width integer type provided by the UAPI headers instead.

- two fixes for the block integrity code
- fix for the newly added newly added PR read keys ioctl, limiting the

acceptable work-around until we can eliminate the reliance on
disk->open_mutex for this
