When CONFIG_COMMON_CLOCK is disabled, the 8996 specific
phy code is left out, which results in a link failure:
ld: drivers/gpu/drm/msm/hdmi/hdmi_phy.o:(.rodata+0x3f0): undefined reference to `msm_hdmi_phy_8996_cfg'
This was only exposed after it became possible to build
test the driver without the clock interfaces.
Make COMMON_CLK a hard dependency for compile testing,
and simplify it a little based on that.

If you happened to try to access `/dev/drm_dp_aux` devices provided by
the MSM DP AUX driver too early at bootup you could go boom. Let's
avoid that by only allowing AUX transfers when the controller is
powered up.
Specifically the crash that was seen (on Chrome OS 5.4 tree with
relevant backports):
Kernel panic - not syncing: Asynchronous SError Interrupt
CPU: 0 PID: 3131 Comm: fwupd Not tainted 5.4.144-16620-g28af11b73efb #1

drm_dp_dpcd_read+0x64/0x10c
auxdev_read_iter+0xd4/0x1c4
I did a little bit of tracing and found that:
* We register the AUX device very early at bootup.
* Power isn't actually turned on for my system until
hpd_event_thread() -> dp_display_host_init() -> dp_power_init()
* You can see that dp_power_init() calls dp_aux_init() which is where
we start allowing AUX channel requests to go through.
In general this patch is a bit of a bandaid but at least it gets us
out of the current state where userspace acting at the wrong time can
fully crash the system.
* I think the more proper fix (which requires quite a bit more
changes) is to power stuff on while an AUX transfer is
happening. This is like the solution we did for ti-sn65dsi86. This
might be required for us to move to populating the panel via the
DP-AUX bus.
* Another fix considered was to dynamically register / unregister. I
tried that at <https://crrev.com/c/3169431/3> but it got
ugly. Currently there's a bug where the pm_runtime() state isn't
tracked properly and that causes us to just keep registering more
and more.

If "data_lanes" property of the dsi output endpoint is missing in
the DT, num_data_lanes would be 0 by default, which could cause
dsi_host_attach() to fail if dsi->lanes is set to a non-zero value
by the bridge driver.
According to the binding document of msm dsi controller, the
input/output endpoint of the controller is expected to have 4 lanes.
So let's set num_data_lanes to 4 by default.

In commit 510410bfc034 ("drm/msm: Implement mmap as GEM object
function") we switched to a new/cleaner method of doing things. That's
good, but we missed a little bit.
Before that commit, we used to _first_ run through the
drm_gem_mmap_obj() case where `obj->funcs->mmap()` was NULL. That meant
that we ran:
vma->vm_flags |= VM_IO | VM_PFNMAP | VM_DONTEXPAND | VM_DONTDUMP;
vma->vm_page_prot = pgprot_writecombine(vm_get_page_prot(vma->vm_flags));
vma->vm_page_prot = pgprot_decrypted(vma->vm_page_prot);
...and _then_ we modified those mappings with our own. Now that
`obj->funcs->mmap()` is no longer NULL we don't run the default
code. It looks like the fact that the vm_flags got VM_IO / VM_DONTDUMP
was important because we're now getting crashes on Chromebooks that
use ARC++ while logging out. Specifically a crash that looks like this
(this is on a 5.10 kernel w/ relevant backports but also seen on a
5.15 kernel):

Let's add the two flags back in.
While we're at it, the fact that we aren't running the default means
that we _don't_ need to clear out VM_PFNMAP, so remove that and save
an instruction.
NOTE: it was confirmed that VM_IO was the important flag to fix the
problem I was seeing, but adding back VM_DONTDUMP seems like a sane
thing to do so I'm doing that too.

- Implement a mask quirk for the Nvidia ION AHCI chip which does not
advertise masking capability despite implementing it. Even worse

to the missing masking capability never get unmasked.
- Move the check which prevents accessing the MSI[X] masking for XEN

Commit aeb58c860dc5 ("thermal/drivers/int340x: processor_thermal: Suppot
64 bit RFIM responses") started using 'readq()' to read 64-bit status
responses from the int340x hardware.
That's all fine and good, but on 32-bit targets a 64-bit 'readq()' is
ambiguous, since it's no longer an atomic access. Some hardware might
require 64-bit accesses, and other hardware might want low word first or
high word first.
It's quite likely that the driver isn't relevant in a 32-bit environment
any more, and there's a patch floating around to just make it depend on
X86_64, but let's make it buildable on x86-32 anyway.
The driver previously just read the low 32 bits, so the hardware
certainly is ok with 32-bit reads, and in a little-endian environment
the low word first model is the natural one.
So just add the include for the 'io-64-nonatomic-lo-hi.h' version.

Since 041284181226 ("of/irq: Allow matching of an interrupt-map local
to an interrupt controller"), the irq code favors using an interrupt-map
over a interrupt-controller property if both are available, while the
earlier behaviour was to ignore the interrupt-map altogether.
However, we now end-up with the opposite behaviour, which is to
ignore the interrupt-controller property even if the interrupt-map
fails to match its input. This new behaviour breaks the AmigaOne
X1000 machine, which ships with an extremely "creative" (read:
broken) device tree.
Fix this by allowing the interrupt-controller property to be selected
when interrupt-map fails to match anything.

When using "devm_request_threaded_irq(,,,,IRQF_ONESHOT,,)" in a driver,
only the first interrupt is handled, and following interrupts are never
delivered (initially reported in [1]).
That's because the RISC-V PLIC cannot EOI masked interrupts, as explained
in the description of Interrupt Completion in the PLIC spec [2]:
<quote>
The PLIC signals it has completed executing an interrupt handler by
writing the interrupt ID it received from the claim to the claim/complete
register. The PLIC does not check whether the completion ID is the same
as the last claim ID for that target. If the completion ID does not match
an interrupt source that *is currently enabled* for the target, the
completion is silently ignored.
</quote>
Re-enable the interrupt before completion if it has been masked during
the handling, and remask it afterwards.

Commit 25b892b583cc ("ARM: dts: arm: Update register-bit-led nodes
'reg' and node names") added a 'reg' property to nodes. This change has
the side effect of changing how the kernel generates the device name.
The assumption was a translatable 'reg' address is unique. However, in
the case of the register-bit-led binding (and a few others) that is not
the case. The 'mask' property must also be used in this case to make a
unique device name.

ACS-3 introduced the ATA Identify Device Data log as mandatory. A
warning message currently signals to the user if a device does not
report supporting this log page in the log directory page, regardless
of the ATA version of the device. Furthermore, this warning will appear
for all attempts at accessing this missing log page during device
revalidation.
Since it is useless to constantly access the log directory and warn
about this lack of support once we have discovered that the device
does not support this log page, introduce the horkage flag
ATA_HORKAGE_NO_ID_DEV_LOG to mark a device as lacking support for
the Identify Device Data log page. Set this flag when
ata_log_supported() returns false in ata_identify_page_supported().
The warning is printed only if the device ATA level is 10 or above
(ACS-3 or above), and only once on device scan. With this flag set, the
log directory page is not accessed again to test for Identify Device
Data log page support.

This reverts commit 2a4d9408c9e8b6f6fc150c66f3fef755c9e20d4a.
Robert reported a NULL pointer dereference caused by the PCI core
(local_pci_probe()) calling the i2c_designware_pci driver's
.runtime_resume() method before the .probe() method. i2c_dw_pci_resume()
depends on initialization done by i2c_dw_pci_probe().
Prior to 2a4d9408c9e8 ("PCI: Use to_pci_driver() instead of
pci_dev->driver"), pci_pm_runtime_resume() avoided calling the
.runtime_resume() method because pci_dev->driver had not been set yet.
2a4d9408c9e8 and b5f9c644eb1b ("PCI: Remove struct pci_dev->driver"),
removed pci_dev->driver, replacing it by device->driver, which *has* been
set by this time, so pci_pm_runtime_resume() called the .runtime_resume()
method when it previously had not.

Pull networking fixes from Jakub Kicinski:
"Including fixes from bpf, can and netfilter.
Current release - regressions:
- bpf: do not reject when the stack read size is different from the
tracked scalar size
- net: fix premature exit from NAPI state polling in napi_disable()
- riscv, bpf: fix RV32 broken build, and silence RV64 warning
Current release - new code bugs:
- net: fix possible NULL deref in sock_reserve_memory
- amt: fix error return code in amt_init(); fix stopping the
workqueue
- ax88796c: use the correct ioctl callback
Previous releases - always broken:
- bpf: stop caching subprog index in the bpf_pseudo_func insn
- security: fixups for the security hooks in sctp
- nfc: add necessary privilege flags in netlink layer, limit
operations to admin only

- bpf, sockmap:
- fix race in ingress receive verdict with redirect to self
- fix incorrect sk_skb data_end access when src_reg = dst_reg
- strparser, and tls are reusing qdisc_skb_cb and colliding
- ethtool: fix ethtool msg len calculation for pause stats
- vlan: fix a UAF in vlan_dev_real_dev() when ref-holder tries to
access an unregistering real_dev
- udp6: make encap_rcv() bump the v6 not v4 stats
- drv: prestera: add explicit padding to fix m68k build
- drv: felix: fix broken VLAN-tagged PTP under VLAN-aware bridge
- drv: mvpp2: fix wrong SerDes reconfiguration order
Misc & small latecomers:
- ipvs: auto-load ipvs on genl access

came up during the 5.16-rc1 merge window.
These include:
- two reverts of xhci and USB core patches that are causing problems
in many systems.
- xhci 3.1 enumeration delay fix for systems that were having
problems.
All three of these have been in linux-next all week with no reported
issues"

MIGRATE_PFN_LOCKED is used to indicate to migrate_vma_prepare() that a
source page was already locked during migrate_vma_collect(). If it
wasn't then the a second attempt is made to lock the page. However if
the first attempt failed it's unlikely a second attempt will succeed,
and the retry adds complexity. So clean this up by removing the retry
and MIGRATE_PFN_LOCKED flag.
Destination pages are also meant to have the MIGRATE_PFN_LOCKED flag
set, but nothing actually checks that.

For some architectures like risc-v and arm64 which use common code
clear_cpu_topology() in shutting down CPUx, When CONFIG_SCHED_CLUSTER
is set, cluster_sibling in cpu_topology of each sibling adjacent
to CPUx is missed clearing, this causes checking failed in
topology_span_sane() and rebuilding topology failure at end when CPU online.
Different sibling's cluster_sibling in cpu_topology[] when CPU92 offline
(CPU 92, 93, 94, 95 are in one cluster):
Before revision:
CPU [92] [93] [94] [95]
cluster_sibling [92] [92-95] [92-95] [92-95]
After revision:
CPU [92] [93] [94] [95]
cluster_sibling [92] [93-95] [93-95] [93-95]
