Pull io_uring updates from Jens Axboe:
"Here are the io_uring changes for this merge window. Light on new
features this time around (just splice + buffer selection), lots of
cleanups, fixes, and improvements to existing support. In particular,
this contains:
- Cleanup fixed file update handling for stack fallback (Hillf)
- Re-work of how pollable async IO is handled, we no longer require
thread offload to handle that. Instead we rely using poll to drive
this, with task_work execution.
- In conjunction with the above, allow expendable buffer selection,
so that poll+recv (for example) no longer has to be a split
operation.
- Make sure we honor RLIMIT_FSIZE for buffered writes
- Add support for splice (Pavel)
- Linked work inheritance fixes and optimizations (Pavel)

Add a separate set of PCS operations, which MAC drivers can use to
couple phylink with their associated MAC PCS layer. The PCS
operations include:
- pcs_get_state() - reads the link up/down, resolved speed, duplex
and pause from the PCS.
- pcs_config() - configures the PCS for the specified mode, PHY
interface type, and setting the advertisement.
- pcs_an_restart() - restarts 802.3 in-band negotiation with the
link partner
- pcs_link_up() - informs the PCS that link has come up, and the
parameters of the link. Link parameters are used to program the
PCS for fixed speed and non-inband modes.

The qed_chain data structure was modified in
commit 1a4a69751f4d ("qed: Chain support for external PBL") to support
receiving an external pbl (due to iWARP FW requirements).
The pages pointed to by the pbl are allocated in qed_chain_alloc
and their virtual address are stored in an virtual addresses array to
enable accessing and freeing the data. The physical addresses however
weren't stored and were accessed directly from the external-pbl
during free.
Destroy-qp flow, leads to freeing the external pbl before the chain is
freed, when the chain is freed it tries accessing the already freed
external pbl, leading to a use-after-free. Therefore we need to store
the physical addresses in additional to the virtual addresses in a
new data structure.

This patch is a trivial passthrough towards the ocelot library, which
support port policers since commit 2c1d029a017f ("net: mscc: ocelot:

library is necessary, for policer parameters.

The approach taken to pass the port policer methods on to drivers is
pragmatic. It is similar to the port mirroring implementation (in that
the DSA core does all of the filter block interaction and only passes
simple operations for the driver to implement) and dissimilar to how
flow-based policers are going to be implemented (where the driver has
full control over the flow_cls_offload data structure).

Ocelot has 384 policers that can be allocated to ingress ports,
QoS classes per port, and VCAP IS2 entries. ocelot_police.c
supports to set policers which can be allocated to police action
of VCAP IS2. We allocate policers from maximum pol_id, and
decrease the pol_id when add a new vcap_is2 entry which is
police action.

When health reporter is registered to devlink, devlink will implicitly set
auto recover if and only if the reporter has a recover method. No reason
to explicitly get the auto recover flag from the driver.
Remove this flag from all drivers that called
devlink_health_reporter_create.
All existing health reporters set auto recovery to true if they have a
recover method.
Yet, administrator can unset auto recover via netlink command as prior to
this patch.

The PTP Hardware Clock (PHC) subsystem offers an API for configuring
programmable pins. User space sets or gets the settings using ioctls,
and drivers verify dialed settings via a callback. Drivers may also
query pin settings by calling the ptp_find_pin() method.
Although the core subsystem protects concurrent access to the pin
settings, the implementation places illogical restrictions on how
drivers may call ptp_find_pin(). When enabling an auxiliary function
via the .enable(on=1) callback, drivers may invoke the pin finding
method, but when disabling with .enable(on=0) drivers are not
permitted to do so. With the exception of the mv88e6xxx, all of the
PHC drivers do respect this restriction, but still the locking pattern
is both confusing and unnecessary.
This patch changes the locking implementation to allow PHC drivers to
freely call ptp_find_pin() from their .enable() and .verify()
callbacks.

In certain cases we should be able to enumerate IO and MEM ranges of all
PCI devices installed in the system, and then set respective host bridge
apertures basing on calculated size and alignment. Particularly when
firmware is broken and fails to assign bridge windows properly, like on
Alpha UP1500 platform.
Actually, almost everything is already in place, and required changes are
minimal:
- add "size_windows" flag to struct pci_host_bridge: when set, it
instructs __pci_bus_size_bridges() to continue with the root bus;
- in the __pci_bus_size_bridges() path: add checks for bus->self,
as it can legitimately be null for the root bus.

Fix the issue by updating all drivers which can access a platform provided
ROM. Instead of calling the helper function pci_platform_rom() which uses
phys_to_virt(), call ioremap() directly on the pdev->rom.
radeon_read_platform_bios() previously directly accessed an __iomem
pointer. Avoid this by calling memcpy_fromio() instead of kmemdup().
pci_platform_rom() now has no remaining callers, so remove it.

ACPICA commit 422166b656565d180bb3aac712009bdce5e70cdd
NHLT (Non-HDAudio Link Table) provides configuration of audio
endpoints for Intel SST (Smart Sound Technology) DSP products.
Similarly to other ACPI tables, data provided by BIOS may not
describe it correctly, thus overriding is required.
ACPI override mechanism checks for unknown signature before
proceeding. Update known signatures array to support NHLT.

ACPICA commit 6ddc19419896e4149ced1b5f35f0dc12516c0399
The AMD IVRS table parsing supported only IVHD type 10h structures.
Parsing an IVHD type 11h caused the iasl to report unknown subtable type.
Add necessary structure definition for IVHD type 11h and apply correct
parsing method based on subtable type.

ASoC: Updates for v5.7
This is a very big update for the core since Morimoto-san has been
rather busy continuing his refactorings to clean up a lot of the cruft
that we have accumilated over the years. We've also gained several new
drivers, including initial (but still not complete) parts of the Intel
SoundWire support.
- Lots of refactorings to modernize the code from Morimoto-san.
- Conversion of SND_SOC_ALL_CODECS to use imply from Geert Uytterhoeven.
- Continued refactoring and fixing of the Intel support.
- Soundwire and more advanced clocking support for Realtek RT5682.
- Support for amlogic GX, Meson 8, Meson 8B and T9015 DAC, Broadcom
DSL/PON, Ingenic JZ4760 and JZ4770, Realtek RL6231, and TI TAS2563 and
TLV320ADCX140.

Add i_last_rd and i_last_wr to ceph_inode_info. These fields are
used to track the last time the client acquired read/write caps for
the inode.
If there is no read/write on an inode for 'caps_wanted_delay_max'
seconds, __ceph_caps_file_wanted() does not request caps for read/write
even there are open files.
Call __ceph_touch_fmode() for dir operations. __ceph_caps_file_wanted()
calculates dir's wanted caps according to last dir read/modification. If
there is recent dir read, dir inode wants CEPH_CAP_ANY_SHARED caps. If
there is recent dir modification, also wants CEPH_CAP_FILE_EXCL.
Readdir is a special case. Dir inode wants CEPH_CAP_FILE_EXCL after
readdir, as with that, modifications do not need to release
CEPH_CAP_FILE_SHARED or invalidate all dentry leases issued by readdir.

With the Octopus release, the MDS will hand out directory create caps.
If we have Fxc caps on the directory, and complete directory information
or a known negative dentry, then we can return without waiting on the
reply, allowing the open() call to return very quickly to userland.
We use the normal ceph_fill_inode() routine to fill in the inode, so we
have to gin up some reply inode information with what we'd expect the
newly-created inode to have. The client assumes that it has a full set
of caps on the new inode, and that the MDS will revoke them when there
is conflicting access.
This functionality is gated on the wsync/nowsync mount options.

Track and correctly handle directory caps for asynchronous operations.
Add aliases for Frc caps that we now designate at Dcu caps (when dealing
with directories).
Unlike file caps, we don't reclaim these when the session goes away, and
instead preemptively release them. In-flight async dirops are instead
handled during reconnect phase. The client needs to re-do a synchronous
operation in order to re-get directory caps.

...and ensure that such requests are never queued. The MDS has need to
know that a request is asynchronous so add flags and proper
infrastructure for that.
Also, delegated inode numbers and directory caps are associated with the
session, so ensure that async requests are always transmitted on the
first attempt and are never queued to wait for session reestablishment.
If it does end up looking like we'll need to queue the request, then
have it return -EJUKEBOX so the caller can reattempt with a synchronous
request.
