Save the memory allocation method used for bpf_local_storage in the
struct explicitly so that we don't need to go through the hassle to
find out the info. When a later patch replaces BPF memory allocator
with kmalloc_noloc(), bpf_local_storage_free() will no longer need
smap->storage_ma to return the memory and completely remove the
dependency on smap in bpf_local_storage_free().

Since selem already saves a pointer to smap, use it instead of an
additional argument in bpf_selem_free(). This requires moving the
SDATA(selem)->smap assignment from bpf_selem_link_map() to
bpf_selem_alloc() since bpf_selem_free() may be called without the
selem being linked to smap in bpf_local_storage_update().

Since commit a96a44aba556 ("bpf: bpf_sk_storage: Fix invalid wait
context lockdep report"), {charge,uncharge}_mem are always true when
allocating a bpf_local_storage_elem or unlinking a bpf_local_storage_elem
from local storage, so drop these arguments. No functional change.

Freezing the request queue from inside sysfs store callbacks may cause a
deadlock in combination with the dm-multipath driver and the
queue_if_no_path option. Additionally, freezing the request queue slows
down system boot on systems where sysfs attributes are set synchronously.
Fix this by removing the blk_mq_freeze_queue() / blk_mq_unfreeze_queue()
calls from the store callbacks that do not strictly need these callbacks.
Add the __data_racy annotation to request_queue.rq_timeout to suppress
KCSAN data race reports about the rq_timeout reads.
This patch may cause a small delay in applying the new settings.
For all the attributes affected by this patch, I/O will complete
correctly whether the old or the new value of the attribute is used.
This patch affects the following sysfs attributes:
* io_poll_delay
* io_timeout
* nomerges
* read_ahead_kb
* rq_affinity
Here is an example of a deadlock triggered by running test srp/002
if this patch is not applied:

Some but not all .ra_pages changes happen while block layer I/O is paused
with blk_mq_freeze_queue(). Filesystems may read .ra_pages even while
block layer I/O is paused, e.g. from inside their .fadvise callback.
Annotating all .ra_pages reads with READ_ONCE() would be cumbersome.
Hence, add the __data_racy annotatation to the .ra_pages member

else try EFI_EDID_DISCOVERED_PROTOCOL, which returns the display device's
native EDID. If no EDID could be retrieved, clear the storage.

should be considered indendent data. The former refers to the graphics

Controller driver probes first, enables link training and scans the bus.
When the PCI bridge is found, its child DT nodes will be scanned and
pwrctrl devices will be created if needed. By the time pwrctrl driver probe
gets called, link training is already enabled by controller driver.
Certain devices like TC9563, which uses the PCI pwrctl framework, need to
configure the device before the PCIe link is up.
As the controller driver already enables link training as part of its
probe, the moment device is powered on, controller and device participate
in link training and link can come up immediately and may not have time to
configure the device.
So we need to stop the link training by using assert_perst() by asserting
PERST# and de-asserting PERST# after device is configured.

The recent fix to properly initialize the tags of the huge zero folio
had an unfortunate not-so-subtle side effect: it caused the actual
*contents* of the huge zero folio to not be initialized at all when the
hardware didn't support the memory tagging.
The reason was the unfortunate semantics of tag_clear_highpage(): on
hardware that didn't do the tagging, it would silently just not do
anything at all. And since this is done only on arm64 with MTE support,
that basically meant most hardware.
It wasn't necessarily immediately obvious since the huge zero page isn't
necessarily very heavily used - or because it might already be zero
because all-zeroes is the most common pattern. But it ends up causing
random odd user space failures when you do hit it.
The unfortunate semantics have been around for a while, but became a
real bug only when we started actively using __GFP_ZEROTAGS in the
generic get_huge_zero_folio() function - before that, it had only ever
been used in code that checked that the hardware supported it.
Fix this by simply changing the semantics of tag_clear_highpage() to
return whether it actually successfully did something or not. While at
it, also make it initialize multiple pages in one go, since that's
actually what the only caller wants it to do and it simplifies the whole
logic.

The goal is to cover systems which shipped with invalid Non HDAudio Link

hardware configuration is invalid too. The table is part of the ACPI
tree and forcing BIOS updates is not a feasible solution. With the

Adds the ppt_* and nv_* tuning knobs that are available via WMI methods
and adds proper min/max levels plus defaults.
The min/max are defined by ASUS and typically gained by looking at what
they allow in the ASUS Armoury Crate application - ASUS does not share
the values outside of this. It could also be possible to gain the AMD
values by use of ryzenadj and testing for the minimum stable value.
The general rule of thumb for adding to the match table is that if the
model range has a single CPU used throughout, then the DMI match can
omit the last letter of the model number as this is the GPU model.
If a min or max value is not provided it is assumed that the particular
setting is not supported. for example ppt_pl2_sppt_min/max is not set.
If a <ppt_setting>_def is not set then the default is assumed to be
<ppt_setting>_max
It is assumed that at least AC settings are available so that the
firmware attributes will be created - if no DC table is available
and power is on DC, then reading the attributes is -ENODEV.

And expand it to encompass all pressure pads.
Definition: "pressure pad" as used here as includes all touchpads that
use physical pressure to convert to click, without physical hinges. Also
called haptic touchpads in general parlance, Synaptics calls them
ForcePads.
Most (all?) pressure pads are currently advertised as
INPUT_PROP_BUTTONPAD. The suggestion to identify them as pressure pads
by defining the resolution on ABS_MT_PRESSURE has been in the docs since
commit 20ccc8dd38a3 ("Documentation: input: define
ABS_PRESSURE/ABS_MT_PRESSURE resolution as grams") but few devices
provide this information.
In userspace it's thus impossible to determine whether a device is a
true pressure pad (pressure equals pressure) or a normal clickpad with
(pressure equals finger size).
Commit 7075ae4ac9db ("Input: add INPUT_PROP_HAPTIC_TOUCHPAD") introduces
INPUT_PROP_HAPTIC_TOUCHPAD but restricted it to those touchpads that
have support for userspace-controlled effects. Let's expand and rename
that definition to include all pressure pad touchpads since those that
do support FF effects can be identified by the presence of the
FF_HAPTIC bit.
This means:
- clickpad: INPUT_PROP_BUTTONPAD
- pressurepad: INPUT_PROP_BUTTONPAD + INPUT_PROP_PRESSUREPAD
- pressurepad with configurable haptics:
INPUT_PROP_BUTTONPAD + INPUT_PROP_PRESSUREPAD + FF_HAPTIC

Currently, on ASUS projects, the TAS2781 codec attaches the speaker GPIO
to the first tasdevice_priv instance using devm. This causes
tas2781_read_acpi to fail on subsequent probes since the GPIO is already
managed by the first device. This causes a failure on Xbox Ally X,
because it has two amplifiers, and prevents us from quirking both the
Xbox Ally and Xbox Ally X in the realtek codec driver.
It is unnecessary to attach the GPIO to a device as it is static.
Therefore, instead of attaching it and then reading it when loading the
firmware, read its value directly in tas2781_read_acpi and store it in
the private data structure. Then, make reading the value non-fatal so
that ASUS projects that miss a speaker pin can still work, perhaps using
fallback firmware.

Syzkaller triggers an invalid memory access issue following fault
injection in update_effective_progs. The issue can be described as
follows:
__cgroup_bpf_detach
update_effective_progs
compute_effective_progs
bpf_prog_array_alloc <-- fault inject
purge_effective_progs
/* change to dummy_bpf_prog */
array->items[index] = &dummy_bpf_prog.prog
---softirq start---
__do_softirq
...
__cgroup_bpf_run_filter_skb
__bpf_prog_run_save_cb
bpf_prog_run
stats = this_cpu_ptr(prog->stats)
/* invalid memory access */
flags = u64_stats_update_begin_irqsave(&stats->syncp)
---softirq end---
static_branch_dec(&cgroup_bpf_enabled_key[atype])
The reason is that fault injection caused update_effective_progs to fail
and then changed the original prog into dummy_bpf_prog.prog in
purge_effective_progs. Then a softirq came, and accessing the members of
dummy_bpf_prog.prog in the softirq triggers invalid mem access.
To fix it, skip updating stats when stats is NULL.

At this point there are very few call chains that might lead to
d_make_discardable() on a dentry that hadn't been made persistent:
calls of simple_unlink() and simple_rmdir() in configfs and
apparmorfs.
Both filesystems do pin (part of) their contents in dcache, but
they are currently playing very unusual games with that. Converting
them to more usual patterns might be possible, but it's definitely
going to be a long series of changes in both cases.
For now the easiest solution is to have both stop using simple_unlink()
and simple_rmdir() - that allows to make d_make_discardable() warn
when given a non-persistent dentry.
Rather than giving them full-blown private copies (with calls of
d_make_discardable() replaced with dput()), let's pull the parts of
simple_unlink() and simple_rmdir() that deal with timestamps and link
counts into separate helpers (__simple_unlink() and __simple_rmdir()
resp.) and have those used by configfs and apparmorfs.

The "phy-mode" property of devicetree indicates whether the PCB has
delay now, which means the mac needs to modify the PHY mode based
on whether there is an internal delay in the mac.
This modification is similar for many ethernet drivers. To simplify
code, define the helper phy_fix_phy_mode_for_mac_delays(speed, mac_txid,
mac_rxid) to fix PHY mode based on whether mac adds internal delay.

Report standard counter stats->rx_missed_errors
using hc_rx_discards_no_wqe from the hardware.
Add a global workqueue to periodically run
mana_query_gf_stats every 2 seconds to get the latest
info in eth_stats and define a driver capability flag
to notify hardware of the periodic queries.
To avoid repeated failures and log flooding, the workqueue
is not rescheduled if mana_query_gf_stats fails on HWC timeout
error and the stats are reset to 0. Other errors are transient
which will not need a VF reset for recovery.

Move hardware counter (HC) statistics from mana_port_context to
mana_context to enable sharing stats across multiple network ports
on the same MANA VF. Previously, each network port queried
hardware counters independently using MANA_QUERY_GF_STAT command
(GF = Generic Function stats from GDMA hardware), resulting in
redundant queries when multiple ports existed on the same device.
Isolate hardware counter stats by introducing mana_ethtool_hc_stats
in mana_context and update the code to ensure all stats are properly
reported via ethtool -S <interface>, maintaining consistency with
previous behavior.

Extend cpu_cache_invalidate_memregion() to support invalidating a
particular range of memory by introducing start and length parameters.
Control of types of invalidation is left for when use cases turn up. For
now everything is Clean and Invalidate.
Where the range is unknown, use the provided cpu_cache_invalidate_all()
helper to act as documentation of intent in a fashion that is clearer than
passing (0, -1) to cpu_cache_invalidate_memregion().

cpu_cache_invalidate_memregion()
The res_desc parameter was originally introduced for documentation purposes
and with the idea that with HDM-DB CXL invalidation could be triggered from
the device. That has not come to pass and the continued existence of the
option is confusing when we add a range in the following patch which might
not be a strict subset of the res_desc. So avoid that confusion by dropping
the parameter.

Add a randomized algorithm that runs newidle balancing proportional to
its success rate.
This improves schbench significantly:
6.18-rc4: 2.22 Mrps/s
6.18-rc4+revert: 2.04 Mrps/s
6.18-rc4+revert+random: 2.18 Mrps/S
Conversely, per Adam Li this affects SpecJBB slightly, reducing it by 1%:
6.17: -6%
6.17+revert: 0%
6.17+revert+random: -1%
