If a subchannel is busy when a close is performed, the subchannel
needs to be quiesced and left nice and tidy, so nothing unexpected
(like a solicited interrupt) shows up while in the closed state.
Unfortunately, the return code from this call isn't checked,
so any busy subchannel is treated as a failing one.
Fix that, so that the close on a busy subchannel happens normally.

Now that neither vfio_ccw_sch_probe() nor vfio_ccw_mdev_probe()
affect the FSM state, it doesn't make sense for their _remove()
counterparts try to revert things in this way. Since the FSM open
and close are handled alongside MDEV open/close, these are
unnecessary.

As pointed out with the simplification of the
VFIO_IOMMU_NOTIFY_DMA_UNMAP notifier [1], the length
parameter was never used to check against the pinned
pages.
Let's correct that, and see if a page is within the
affected range instead of simply the first page of
the range.

SPI NOR core changes:
- move SECT_4K_PMC flag out of the core as it's a vendor specific flag
- s/addr_width/addr_nbytes: address width means the number of IO lines
used for the address, whereas in the code it is used as the number of
address bytes.
- do not change nor->addr_nbytes at SFDP parsing time. At the SFDP parsing
time we should not change members of struct spi_nor, but instead fill
members of struct spi_nor_flash_parameters which could later on be used
by the callers.
- track flash's internal address mode so that we can use 4B opcodes
together with opcodes that don't have a 4B opcode correspondent.
SPI NOR manufacturer drivers changes:
- esmt: Rename "f25l32qa" flash name to "f25l32qa-2s".
- micron-st: Skip FSR reading if SPI controller does not support it to
allow flashes that support FSR to work even when attached to such SPI
controllers.
- spansion: Add s25hl-t/s25hs-t IDs and fixups.

Currently nfp driver will reject to offload tunnel key action without

Pull scheduler updates from Ingo Molnar:
"Load-balancing improvements:
- Improve NUMA balancing on AMD Zen systems for affine workloads.
- Improve the handling of reduced-capacity CPUs in load-balancing.
- Energy Model improvements: fix & refine all the energy fairness
metrics (PELT), and remove the conservative threshold requiring 6%
energy savings to migrate a task. Doing this improves power
efficiency for most workloads, and also increases the reliability
of energy-efficiency scheduling.
- Optimize/tweak select_idle_cpu() to spend (much) less time
searching for an idle CPU on overloaded systems. There's reports of
several milliseconds spent there on large systems with large
workloads ...
[ Since the search logic changed, there might be behavioral side
effects. ]
- Improve NUMA imbalance behavior. On certain systems with spare
capacity, initial placement of tasks is non-deterministic, and such
an artificial placement imbalance can persist for a long time,
hurting (and sometimes helping) performance.
The fix is to make fork-time task placement consistent with runtime
NUMA balancing placement.
Note that some performance regressions were reported against this,
caused by workloads that are not memory bandwith limited, which
benefit from the artificial locality of the placement bug(s). Mel
Gorman's conclusion, with which we concur, was that consistency is
better than random workload benefits from non-deterministic bugs:
"Given there is no crystal ball and it's a tradeoff, I think
it's better to be consistent and use similar logic at both fork
time and runtime even if it doesn't have universal benefit."
- Improve core scheduling by fixing a bug in
sched_core_update_cookie() that caused unnecessary forced idling.
- Improve wakeup-balancing by allowing same-LLC wakeup of idle CPUs
for newly woken tasks.
- Fix a newidle balancing bug that introduced unnecessary wakeup
latencies.
ABI improvements/fixes:
- Do not check capabilities and do not issue capability check denial
messages when a scheduler syscall doesn't require privileges. (Such
as increasing niceness.)
- Add forced-idle accounting to cgroups too.
- Fix/improve the RSEQ ABI to not just silently accept unknown flags.
(No existing tooling is known to have learned to rely on the
previous behavior.)
- Depreciate the (unused) RSEQ_CS_FLAG_NO_RESTART_ON_* flags.
Optimizations:
- Optimize & simplify leaf_cfs_rq_list()
- Micro-optimize set_nr_{and_not,if}_polling() via try_cmpxchg().
Misc fixes & cleanups:
- Fix the RSEQ self-tests on RISC-V and Glibc 2.35 systems.
- Fix a full-NOHZ bug that can in some cases result in the tick not
being re-enabled when the last SCHED_RT task is gone from a
runqueue but there's still SCHED_OTHER tasks around.
- Various PREEMPT_RT related fixes.
- Misc cleanups & smaller fixes"

1GbE Intel Wired LAN Driver Updates 2022-07-28
Jacob Keller says:
Convert all of the Intel drivers with PTP support to the newer .adjfine
implementation which uses scaled parts per million.
This improves the precision of the frequency adjustments by taking advantage
of the full scaled parts per million input coming from user space.
In addition, all implementations are converted to using the
mul_u64_u64_div_u64 function which better handles the intermediate value.
This function supports architecture specific instructions where possible to
avoid loss of precision if the normal 64-bit multiplication would overflow.
Of note, the i40e implementation is now able to avoid loss of precision on
slower link speeds by taking advantage of this to multiply by the link speed
factor first. This results in a significantly more precise adjustment by
allowing the calculation to impact the lower bits.
This also gets us a step closer to being able to remove the .adjfreq
entirely by removing its use from many drivers.
I plan to follow this up with a series to update the drivers from other
vendors and drop the .adjfreq implementation entirely.
* '1GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:

remains enabled and the boot time is no longer slowed to a crawl
for systems which require the late remapping
- Enable support for direct swapping of 2MiB transparent huge-pages
on systems without MTE
- Fix handling of MTE tags with allocating new pages with HW KASAN
- Expose the SMIDR register to userspace via sysfs
- Continued rework of the stack unwinder, particularly improving the
behaviour under KASAN
- More repainting of our system register definitions to match the
architectural terminology
- Improvements to the layout of the vDSO objects
- Support for allocating additional bits of HWCAP2 and exposing
FEAT_EBF16 to userspace on CPUs that support it

The P2SB library is used for various drivers, including server

By now all the functions fun_xdp_tx() calls are shared with the skb path
and thus are fragment-capable. Update fun_xdp_tx(), that up to now has
been passing just one buffer, to check for fragments and call
accordingly. This makes XDP_TX and ndo_xdp_xmit fragment-capable.

Commit fa1f57421e0b ("xen/virtio: Enable restricted memory access using
Xen grant mappings") introduced a new requirement for using virtio
devices: the backend now needs to support the VIRTIO_F_ACCESS_PLATFORM
feature.
This is an undue requirement for non-PV guests, as those can be operated
with existing backends without any problem, as long as those backends
are running in dom0.
Per default allow virtio devices without grant support for non-PV
guests.
On Arm require VIRTIO_F_ACCESS_PLATFORM for devices having been listed
in the device tree to use grants.
Add a new config item to always force use of grants for virtio.

Instead of having a global flag to require restricted memory access
for all virtio devices, introduce a callback which can select that
requirement on a per-device basis.
For convenience add a common function returning always true, which can
be used for use cases like SEV.
Per default use a callback always returning false.
As the callback needs to be set in early init code already, add a
virtio anchor which is builtin in case virtio is enabled.

Currently when the toolstack issues a reboot, it gets translated into a
call to ctrl_alt_del(). But tying reboot to ctrl-alt-del means rebooting
may fail if e.g. the user has masked the ctrl-alt-del.target under
systemd.
A previous attempt to fix this issue made a change that sets the
kernel.ctrl-alt-del sysctl to 1 before ctrl_alt_del() is called.
However, this doesn't give userspace the opportunity to block rebooting
or even do any cleanup or syncing.
Instead, call orderly_reboot() which will call the "reboot" command,
giving userspace the opportunity to block it or perform the usual reboot
process while being independent of the ctrl-alt-del behaviour. It also
matches what happens in the shutdown case.

Set ret to 0 (success) before entering first if statement, thereby
assuring that even if the device is not associated and further checks
pass, we do not then end up returning the uninitialized value of ret.
This assignment is deliberately now directly before the if statement, in
order to keep it clear what is happening as opposed to having it as an
initialization at the start of the function like it was originally.
Also add a comment to make it clear this first if block is currently a
success path. As a side note, smatch does not trigger warnings for this
change, for me at least.
Within core/rtw_pwrctrl.c in the rtw_pwr_wakeup function, I previously
dropped the initialization of 'ret' (int ret = 0;) in favour of its
assignment which happens inside the first if block directly before its
corresponding goto. This was the cause of this bug, and was introduced
by: commit f3a76018dd55 ("staging: r8188eu: remove initializer from ret
in rtw_pwr_wakeup").

The driver core supports the ability to handle the creation and removal
of device-specific sysfs files in a race-free manner. Take advantage of
that by converting this driver to use this by moving the sysfs
attributes into a group and assigning the dev_groups pointer to it.

Representors do not want to be subject to the PF's Ethernet address
filters, since traffic from VFs will typically have a destination
either elsewhere on the link segment or on an overlay network.
So, create a dynamic m-port with promiscuous and all-multicast
filters, and set it as the egress port of representor default rules.
Since the m-port is an alias of the calling PF's own m-port, traffic
will still be delivered to the PF's RXQs, but it will be subject to
the VNRX filter rules installed on the dynamic m-port (specified by
the v-port ID field of the filter spec).
