If CONFIG_OF is disabled and the ahci_st driver is builtin (or
CONFIG_MODULES is disabled), then using the macro of_match_ptr()
results in the st_ahci_match variable being unused, which generates a
compilation warning and a compilation error if CONFIG_WERROR is enabled.
Fix this by directly assigning st_ahci_match to .of_match_table in the
st_ahci_driver platform driver definition.

This happens because sata_pmp_init_links() initialize link->pmp up to
SATA_PMP_MAX_PORTS while em_priv is declared as 8 elements array.
I can't find the maximum Enclosure Management ports specified in AHCI
spec v1.3.1, but "12.2.1 LED message type" states that "Port Multiplier
Information" can utilize 4 bits, which implies it can support up to 16
ports. Hence, use SATA_PMP_MAX_PORTS as EM_MAX_SLOTS to resolve the
issue.

git://git.kernel.org/pub/scm/linux/kernel/git/crng/random
Pull more random number generator updates from Jason Donenfeld:
"This time with some large scale treewide cleanups.
The intent of this pull is to clean up the way callers fetch random
integers. The current rules for doing this right are:
- If you want a secure or an insecure random u64, use get_random_u64()
- If you want a secure or an insecure random u32, use get_random_u32()
The old function prandom_u32() has been deprecated for a while
now and is just a wrapper around get_random_u32(). Same for
get_random_int().
- If you want a secure or an insecure random u16, use get_random_u16()
- If you want a secure or an insecure random u8, use get_random_u8()
- If you want secure or insecure random bytes, use get_random_bytes().
The old function prandom_bytes() has been deprecated for a while
now and has long been a wrapper around get_random_bytes()
- If you want a non-uniform random u32, u16, or u8 bounded by a
certain open interval maximum, use prandom_u32_max()
I say "non-uniform", because it doesn't do any rejection sampling
or divisions. Hence, it stays within the prandom_*() namespace, not
the get_random_*() namespace.
I'm currently investigating a "uniform" function for 6.2. We'll see
what comes of that.
By applying these rules uniformly, we get several benefits:
- By using prandom_u32_max() with an upper-bound that the compiler
can prove at compile-time is ≤65536 or ≤256, internally
get_random_u16() or get_random_u8() is used, which wastes fewer
batched random bytes, and hence has higher throughput.
- By using prandom_u32_max() instead of %, when the upper-bound is
not a constant, division is still avoided, because
prandom_u32_max() uses a faster multiplication-based trick instead.
- By using get_random_u16() or get_random_u8() in cases where the
return value is intended to indeed be a u16 or a u8, we waste fewer
batched random bytes, and hence have higher throughput.
This series was originally done by hand while I was on an airplane
without Internet. Later, Kees and I worked on retroactively figuring
out what could be done with Coccinelle and what had to be done
manually, and then we split things up based on that.
So while this touches a lot of files, the actual amount of code that's
hand fiddled is comfortably small"

Pull more clk updates from Stephen Boyd:
"This is the final part of the clk patches for this merge window.
The clk rate range series needed another week to fully bake. Maxime
fixed the bug that broke clk notifiers and prevented this from being
included in the first pull request. He also added a unit test on top
to make sure it doesn't break so easily again. The majority of the
series fixes up how the clk_set_rate_*() APIs work, particularly
around when the rate constraints are dropped and how they move around
when reparenting clks. Overall it's a much needed improvement to the
clk rate range APIs that used to be pretty broken if you looked
sideways.
Beyond the core changes there are a few driver fixes for a compilation
issue or improper data causing clks to fail to register or have the
wrong parents. These are good to get in before the first -rc so that
the system actually boots on the affected devices"

Commit 68b99e94a4a2 ("thermal: intel_powerclamp: Use get_cpu() instead
of smp_processor_id() to avoid crash") fixed an issue related to using
smp_processor_id() in preemptible context by replacing it with a pair
of get_cpu()/put_cpu(), but what is needed there really is any online
CPU and not necessarily the one currently running the code. Arguably,
getting the one that's running the code in there is confusing.
For this reason, simply give the control CPU role to the first online
one which automatically will be CPU0 if it is online, so one check
can be dropped from the code for an added benefit.

Changing a VF's mac address through the VF (rather than via the PF)
fails with EPERM because the latter part of efx_ef10_set_mac_address
attempts to change the vport mac address list as the VF.
Even with this fixed it still fails with EBUSY because the vadaptor
is still assigned on the VF - the vadaptor reassignment must be within
a section where the VF has torn down its state.
A major reason this has broken is because we have two functions that
ostensibly do the same thing - have a PF and VF cooperate to change a
VF mac address. Rather than do this, if we are changing the mac of a VF
that has a link to the PF in the same VM then simply call
sriov_set_vf_mac instead, which is a proven working function that does
that.
If there is no PF available, or that fails non-fatally, then attempt to
change the VF's mac address as we would a PF, without updating the PF's
data.
Test case:
Create a VF:
echo 1 > /sys/class/net/<if>/device/sriov_numvfs
Set the mac address of the VF directly:
ip link set <vf> addr 00:11:22:33:44:55
Set the MAC address of the VF via the PF:
ip link set <pf> vf 0 mac 00:11:22:33:44:66
Without this patch the last command will fail with ENOENT.

Commit 8c193f4714df ("pwm: tegra: Optimize period calculation") updated
the period calculation in the Tegra PWM driver and now returns an error
if the period requested is less than minimum period supported. This is
breaking PWM support on various Tegra platforms. For example, on the
Tegra210 Jetson Nano platform this is breaking the PWM fan support and
probing the PWM fan driver now fails ...
pwm-fan pwm-fan: Failed to configure PWM: -22
pwm-fan: probe of pwm-fan failed with error -22
The problem is that the default parent clock for the PWM on Tegra210 is
a 32kHz clock and is unable to support the requested PWM period.
Fix PWM support on Tegra20, Tegra30, Tegra114, Tegra124 and Tegra210 by
updating the parent clock for the PWM to be the PLL_P.

These two clocks are now registered in the device tree as fixed clocks,
causing a regression in the driver as the clock already exists with
e.g. the name "pxo_board" as the MSM8660 GCC driver probes.
Fix this by just not hard-coding this anymore and everything works
like a charm.

Since commit 262ca38f4b6e ("clk: Stop forwarding clk_rate_requests
to the parent"), the clk_rate_request is .. as the title says, not
forwarded anymore to the parent: this produces an issue with the
MediaTek clock MUX driver during GPU DVFS on MT8195, but not on
MT8192 or others.
This is because, differently from others, like MT8192 where all of
the clocks in the MFG parents tree are of mtk_mux type, but in the
parent tree of MT8195's MFG clock, we have one mtk_mux clock and
one (clk framework generic) mux clock, like so:
names: mfg_bg3d -> mfg_ck_fast_ref -> top_mfg_core_tmp (or) mfgpll
types: mtk_gate -> mux -> mtk_mux (or) mtk_pll
To solve this issue and also keep the GPU DVFS clocks code working
as expected, wire up a .determine_rate() callback for the mtk_mux
ops; for that, the standard clk_mux_determine_rate_flags() was used
as it was possible to.
This commit was successfully tested on MT6795 Xperia M5, MT8173 Elm,
MT8192 Spherion and MT8195 Tomato; no regressions were seen.
For the sake of some more documentation about this issue here's the
trace of it:

Passed to xen_grant_dma_map_page() offset in the page
can be > PAGE_SIZE even if the guest uses the same page granularity
as Xen (4KB).
Before current patch, if such case happened we ended up providing
grants for the whole region in xen_grant_dma_map_page() which
was really unnecessary. The more, we ended up not releasing all
grants which represented that region in xen_grant_dma_unmap_page().
Current patch updates the code to be able to deal with such cases.

Newer DualSense firmware supports a revised classic rumble mode,
which feels more similar to rumble as supported on previous PlayStation
controllers. It has been made the default on PlayStation and non-PlayStation
devices now (e.g. iOS and Windows). Default to this new mode when
supported.

Provide initial support for the DualSense Edge controller. The brings
support up to the level of the original DualSense, but won't yet provide
support for new features (e.g. reprogrammable buttons).

Ensure we don't schedule any new output work on removal and wait
for any existing work to complete. If we don't do this e.g. rumble
work can get queued during deletion and we trigger a kernel crash.

Under certain conditions the Magic Trackpad can group 2 reports in a
single packet. The packet is split and the raw event function is
invoked recursively for each part.
However, after processing each part, the BTN_MOUSE status is updated,
sending multiple click events. [1]
Return after processing double reports to avoid this issue.

Independend of the current graphics resolution, adjust the reported
graphics card memory size to the next 4MB boundary.
This fixes the fbtest program which expects a naturally aligned size.

For FT2000+/64 devices,
when four virtual machines share the same physical network interface,
DROP will occur due to the single core CPU performance problem.
ip_check_defrag and macvlan_process_broadcast is on the same CPU.
When the MACVLAN PORT increases, the CPU usage reaches more than 90%.
bc_queue > bc_queue_len_used (default 1000), causing DROP.
