Pull x86 SEV updates from Borislav Petkov:
- A segmented Reverse Map table (RMP) is a across-nodes distributed
table of sorts which contains per-node descriptors of each node-local
4K page, denoting its ownership (hypervisor, guest, etc) in the realm
of confidential computing. Add support for such a table in order to
improve referential locality when accessing or modifying RMP table
entries
- Add support for reading the TSC in SNP guests by removing any
interference or influence the hypervisor might have, with the goal of
making a confidential guest even more independent from the hypervisor

Merged the 'fixes' branch into the 'for-next' branch to resolve
a conflict in alienware-wmi zone teardown code.

The use of R7 in the SMCCC conflicts with the compiler's use of R7 as a frame
pointer in Thumb2 mode, which is forcibly enabled by Clang when profiling
hooks are inserted via the -pg switch.
This is a known issue and similar driver workaround this with a Makefile
ifdef. Exact workaround are applied in
drivers/firmware/arm_scmi/transports/Makefile and other similar driver.

When enabling a pass-through port an interrupt might come before psmouse
driver binds to the pass-through port. However synaptics sub-driver
tries to access psmouse instance presumably associated with the
pass-through port to figure out if only 1 byte of response or entire
protocol packet needs to be forwarded to the pass-through port and may
crash if psmouse instance has not been attached to the port yet.
Fix the crash by introducing open() and close() methods for the port and
check if the port is open before trying to access psmouse instance.
Because psmouse calls serio_open() only after attaching psmouse instance
to serio port instance this prevents the potential crash.

Microsoft defined Meta+Shift+F23 as the Copilot shortcut instead of a
dedicated keycode, and multiple vendors have their keyboards emit this
sequence in response to users pressing a dedicated "Copilot" key.
Unfortunately the default keymap table in atkbd does not map scancode
0x6e (F23) and so the key combination does not work even if userspace
is ready to handle it.
Because this behavior is common between multiple vendors and the
scancode is currently unused map 0x6e to keycode 193 (KEY_F23) so that
key sequence is generated properly.
MS documentation for the scan code:
https://learn.microsoft.com/en-us/windows/win32/inputdev/about-keyboard-input#scan-codes
Confirmed on Lenovo, HP and Dell machines by Canonical.
Tested on Lenovo T14s G6 AMD.

We are missing netif_napi_del() and am65_cpsw_nuss_free_tx/rx_chns()
in error path when am65_cpsw_nuss_init_tx/rx_chns() is used anywhere
other than at probe(). i.e. am65_cpsw_nuss_update_tx_rx_chns and
am65_cpsw_nuss_resume()
As reported, in am65_cpsw_nuss_update_tx_rx_chns(),
if am65_cpsw_nuss_init_tx_chns() partially fails then
devm_add_action(dev, am65_cpsw_nuss_free_tx_chns,..) is added
but the cleanup via am65_cpsw_nuss_free_tx_chns() will not run.
Same issue exists for am65_cpsw_nuss_init_tx/rx_chns() failures
in am65_cpsw_nuss_resume() as well.
This would otherwise require more instances of devm_add/remove_action
and is clearly more of a distraction than any benefit.
So, drop devm_add/remove_action for am65_cpsw_nuss_free_tx/rx_chns()
and call am65_cpsw_nuss_free_tx/rx_chns() and netif_napi_del()
where required.

Two different models of usb card, the drivers are r8152 and asix. If no
network cable is connected, Speed = 10Mb/s. This problem is repeated in
linux 3.10, 4.19, 5.4, 6.12. This problem also exists on the latest
kernel. Both drivers call mii_ethtool_get_link_ksettings,
but the value of cmd->base.speed in this
function can only be SPEED_1000 or SPEED_100 or SPEED_10.
When the network cable is not connected, set cmd->base.speed
=SPEED_UNKNOWN.

300-400B RPC requests are fairly common. With the current default
of 256B HDS threshold bnxt ends up splitting those, lowering PCIe
bandwidth efficiency and increasing the number of memory allocation.
Increase the HDS threshold to fit 4 buffers in a 4k page.
This works out to 640B as the threshold on a typical kernel confing.
This change increases the performance for a microbenchmark which
receives 400B RPCs and sends empty responses by 4.5%.
Admittedly this is just a single benchmark, but 256B works out to
just 6 (so 2 more) packets per head page, because shinfo size
dominates the headers.
Now that we use page pool for the header pages I was also tempted
to default rx_copybreak to 0, but in synthetic testing the copybreak
size doesn't seem to make much difference.

Now that we can configure HDS threshold separately from the rx_copybreak
HDS threshold may be higher than rx_copybreak.
We need to make sure that we have enough space for the headers.

Separate the HDS config from the ethtool state struct.
The HDS config contains just simple parameters, not state.
Having it as a separate struct will make it easier to clone / copy
and also long term potentially make it per-queue.

Pull misc vfs updates from Christian Brauner:
"Features:
- Support caching symlink lengths in inodes
The size is stored in a new union utilizing the same space as
i_devices, thus avoiding growing the struct or taking up any more
space
When utilized it dodges strlen() in vfs_readlink(), giving about
1.5% speed up when issuing readlink on /initrd.img on ext4
- Add RWF_DONTCACHE iocb and FOP_DONTCACHE file_operations flag
If a file system supports uncached buffered IO, it may set
FOP_DONTCACHE and enable support for RWF_DONTCACHE.
If RWF_DONTCACHE is attempted without the file system supporting
it, it'll get errored with -EOPNOTSUPP
- Enable VBOXGUEST and VBOXSF_FS on ARM64
Now that VirtualBox is able to run as a host on arm64 (e.g. the
Apple M3 processors) we can enable VBOXSF_FS (and in turn
VBOXGUEST) for this architecture.
Tested with various runs of bonnie++ and dbench on an Apple MacBook
Pro with the latest Virtualbox 7.1.4 r165100 installed
Cleanups:
- Delay sysctl_nr_open check in expand_files()
- Use kernel-doc includes in fiemap docbook
- Use page->private instead of page->index in watch_queue
- Use a consume fence in mnt_idmap() as it's heavily used in
link_path_walk()
- Replace magic number 7 with ARRAY_SIZE() in fc_log
- Sort out a stale comment about races between fd alloc and dup2()
- Fix return type of do_mount() from long to int
- Various cosmetic cleanups for the lockref code
Fixes:
- Annotate spinning as unlikely() in __read_seqcount_begin
The annotation already used to be there, but got lost in commit
52ac39e5db51 ("seqlock: seqcount_t: Implement all read APIs as
statement expressions")
- Fix proc_handler for sysctl_nr_open
- Flush delayed work in delayed fput()
- Fix grammar and spelling in propagate_umount()
- Fix ESP not readable during coredump
In /proc/PID/stat, there is the kstkesp field which is the stack
pointer of a thread. While the thread is active, this field reads
zero. But during a coredump, it should have a valid value

The fault->mutex serializes the fault read()/write() fops and the
iommufd_fault_auto_response_faults(), mainly for fault->response. Also, it
was conveniently used to fence the fault->deliver in poll() fop and
iommufd_fault_iopf_handler().
However, copy_from/to_user() may sleep if pagefaults are enabled. Thus,
they could take a long time to wait for user pages to swap in, blocking
iommufd_fault_iopf_handler() and its caller that is typically a shared IRQ
handler of an IOMMU driver, resulting in a potential global DOS.
Instead of reusing the mutex to protect the fault->deliver list, add a
separate spinlock, nested under the mutex, to do the job.
iommufd_fault_iopf_handler() would no longer be blocked by
copy_from/to_user().
Add a free_list in iommufd_auto_response_faults(), so the spinlock can
simply fence a fast list_for_each_entry_safe routine.
Provide two deliver list helpers for iommufd_fault_fops_read() to use:
- Fetch the first iopf_group out of the fault->deliver list
- Restore an iopf_group back to the head of the fault->deliver list
Lastly, move the mutex closer to the response in the fault structure,
and update its kdoc accordingly.

ASoC: Updates for v6.14
This was quite a quiet release for what I imagine are holiday related
reasons, the diffstat is dominated by some Cirrus Logic Kunit tests.
There's the usual mix of small improvements and fixes, plus a few new

work on HDMI audio.
- Allow clocking on each DAI in an audio graph card to be configured
separately.
- Improved power management for Renesas RZ-SSI.
- KUnit testing for the Cirrus DSP framework.
- Memory to meory operation support for Freescale/NXP platforms.
- Support for pause operations in SOF.
- Support for Allwinner suinv F1C100s, Awinc AW88083, Realtek

Since adding negotiation of in-band capabilities, it is no longer
sufficient to just look at the MLO_AN_xxx mode and PHY interface to
decide whether to do a major configuration, since the result now
depends on the capabilities of the attaching PHY.
Always trigger a major configuration in this case.

negative error value on error. So not NULL check is not sufficient
to deteremine if IRQ is valid. Check that IRQ is greater then zero
to ensure it is valid.
There is no issue at probe time but at runtime user can invoke
.set_channels which results in the following call chain.
am65_cpsw_set_channels()
am65_cpsw_nuss_update_tx_rx_chns()
am65_cpsw_nuss_remove_tx_chns()
am65_cpsw_nuss_init_tx_chns()
At this point if am65_cpsw_nuss_init_tx_chns() fails due to
k3_udma_glue_tx_get_irq() then tx_chn->irq will be set to a
negative value.
Then, at subsequent .set_channels with higher channel count we
will attempt to free an invalid IRQ in am65_cpsw_nuss_remove_tx_chns()
leading to a kernel warning.
The issue is present in the original commit that introduced this driver,
although there, am65_cpsw_nuss_update_tx_rx_chns() existed as
am65_cpsw_nuss_update_tx_chns().

Replace ternary (condition ? "enable" : "disable") syntax with helpers
from string_choices.h because:
1. Simple function call with one argument is easier to read. Ternary
operator has three arguments and with wrapping might lead to quite
long code.
2. Is slightly shorter thus also easier to read.
3. It brings uniformity in the text - same string.
4. Allows deduping by the linker, which results in a smaller binary
file.
