Expose min_wait_usec in io_uring_getevents_arg, replacing the pad member
that is currently in there. The value is in usecs, which is explained in
the name as well.
Note that if min_wait_usec and a normal timeout is used in conjunction,
the normal timeout is still relative to the base time. For example, if
min_wait_usec is set to 100 and the normal timeout is 1000, the max
total time waited is still 1000. This also means that if the normal
timeout is shorter than min_wait_usec, then only the min_wait_usec will
take effect.
See previous commit for an explanation of how this works.
IORING_FEAT_MIN_TIMEOUT is added as a feature flag for this, as
applications doing submit_and_wait_timeout() style operations will
generally not see the -EINVAL from the wait side as they return the
number of IOs submitted. Only if no IOs are submitted will the -EINVAL
bubble back up to the application.

Add a new registration opcode IORING_REGISTER_CLOCK, which allows the
user to select which clock id it wants to use with CQ waiting timeouts.
It only allows a subset of all posix clocks and currently supports

When net devices propagate xdp configurations to slave devices,
we will need to perform a memory provider check to ensure we're
not binding xdp to a device using unreadable netmem.
Currently the ->ndo_bpf calls in a few places. Adding checks to all
these places would not be ideal.
Refactor all the ->ndo_bpf calls into one place where we can add this
check in the future.

Algorithm registration is usually carried out during module init,
where as little work as possible should be carried out. The SIMD
code violated this rule by allocating a tfm, this then triggers a
full test of the algorithm which may dead-lock in certain cases.
SIMD is only allocating the tfm to get at the alg object, which is
in fact already available as it is what we are registering. Use
that directly and remove the crypto_alloc_tfm call.
Also remove some obsolete and unused SIMD API.

No consumers anymore, remove it. After this, insertion of policies
no longer require list walk of all inexact policies but only those
that are reachable via the candidate sets.
This gives almost linear insertion speeds provided the inserted
policies are for non-overlapping networks.
Before:
Inserted 1000 policies in 70 ms
Inserted 10000 policies in 1155 ms
Inserted 100000 policies in 216848 ms
After:
Inserted 1000 policies in 56 ms
Inserted 10000 policies in 478 ms
Inserted 100000 policies in 4580 ms
Insertion of 1m entries takes about ~40s after this change

Currently, users can only stash kptr into map values with bpf_kptr_xchg().
This patch further supports stashing kptr into local kptr by adding local
kptr as a valid destination type.
When stashing into local kptr, btf_record in program BTF is used instead
of btf_record in map to search for the btf_field of the local kptr.
The local kptr specific checks in check_reg_type() only apply when the
source argument of bpf_kptr_xchg() is local kptr. Therefore, we make the
scope of the check explicit as the destination now can also be local kptr.

ARG_PTR_TO_KPTR is currently only used by the bpf_kptr_xchg helper.
Although it limits reg types for that helper's first arg to
PTR_TO_MAP_VALUE, any arbitrary mapval won't do: further custom
verification logic ensures that the mapval reg being xchgd-into is
pointing to a kptr field. If this is not the case, it's not safe to xchg
into that reg's pointee.
Let's rename the bpf_arg_type to more accurately describe the fairly
specific expectations that this arg type encodes.
This is a nonfunctional change.

Link topologies containing multiple network PHYs attached to the same
net_device can be found when using a PHY as a media converter for use
with an SFP connector, on which an SFP transceiver containing a PHY can
be used.
With the current model, the transceiver's PHY can't be used for
operations such as cable testing, timestamping, macsec offload, etc.
The reason being that most of the logic for these configuration, coming
from either ethtool netlink or ioctls tend to use netdev->phydev, which
in multi-phy systems will reference the PHY closest to the MAC.
Introduce a numbering scheme allowing to enumerate PHY devices that
belong to any netdev, which can in turn allow userspace to take more
precise decisions with regard to each PHY's configuration.
The numbering is maintained per-netdev, in a phy_device_list.
The numbering works similarly to a netdevice's ifindex, with
identifiers that are only recycled once INT_MAX has been reached.
This prevents races that could occur between PHY listing and SFP
transceiver removal/insertion.
The identifiers are assigned at phy_attach time, as the numbering
depends on the netdevice the phy is attached to. The PHY index can be
re-used for PHYs that are persistent.

filemap_create_folio() and do_read_cache_folio() were always allocating
folio of order 0. __filemap_get_folio was trying to allocate higher
order folios when fgp_flags had higher order hint set but it will default
to order 0 folio if higher order memory allocation fails.
Supporting mapping_min_order implies that we guarantee each folio in the
page cache has at least an order of mapping_min_order. When adding new
folios to the page cache we must also ensure the index used is aligned to
the mapping_min_order as the page cache requires the index to be aligned
to the order of the folio.

We need filesystems to be able to communicate acceptable folio sizes
to the pagecache for a variety of uses (e.g. large block sizes).
Support a range of folio sizes between order-0 and order-31.

The iommu_report_device_fault function was updated to return void while
assuming that drivers only need to call iommu_report_device_fault() for
reporting an iopf. This implementation causes following problems:
1. The drivers rely on the core code to call it's page_reponse,
however, when a fault is received and no fault capable domain is
attached / iopf_param is NULL, the ops->page_response is NOT called
causing the device to stall in case the fault type was PAGE_REQ.
2. The arm_smmu_v3 driver relies on the returned value to log errors
returning void from iommu_report_device_fault causes these events to
be missed while logging.
Modify the iommu_report_device_fault function to return -EINVAL for
cases where no fault capable domain is attached or iopf_param was NULL
and calls back to the driver (ops->page_response) in case the fault type
was IOMMU_FAULT_PAGE_REQ. The returned value can be used by the drivers
to log the fault/event as needed.

Bart Van Assche <bvanassche@acm.org> says:
Hi Martin,
Multiple SCSI drivers use snprintf() to format a workqueue name before
invoking one of the create*_workqueue() macros. This patch series
simplifies such code by passing the format string and arguments to
alloc_workqueue(). Additionally, the structure members that are only
used as a temporary buffer for formatting workqueue names are
removed. Please consider this patch series for the next merge window.
Thanks,
Bart.

GCC already checks for arguments that are marked with the "nonstring"[1]
attribute when used on standard C String API functions (e.g. strcpy). Gain
this compile-time checking also for the kernel's primary string copying
function, strscpy().
Note that Clang has neither "nonstring" nor __builtin_has_attribute().

flexible array
Replace the deprecated[1] use of a 1-element array in
struct vmmdev_hgcm_pagelist with a modern flexible array. As this is
UAPI, we cannot trivially change the size of the struct, so use a union
to retain the old first element's size, but switch "pages" to a flexible
array.
No binary differences are present after this conversion.
