HID: asus: only support backlight when it's not driven by WMI
The Asus GL502VSK has the same 0B05:1837 keyboard as we've seen in
several Republic of Gamers laptops.
However, in this model, the keybard backlight control exposed by hid-asus
has no effect on the keyboard backlight. Instead, the keyboard
backlight is correctly driven by asus-wmi.
With two keyboard backlight devices available (and only the acer-wmi
one working), GNOME is picking the wrong one to drive in the UI.
Avoid this problem by not creating the backlight interface when we
detect a WMI-driven keyboard backlight.
We have also tested Asus GL702VMK which does have the hid-asus
backlight present, and it still works fine with this patch (WMI method
call returns UNSUPPORTED_METHOD).
A direct "depends on ASUS_WMI" is intentionally avoided so that HID_ASUS
users who have ASUS_WMI=n will not quietly lose their HID_ASUS driver on
a kernel upgrade.

platform/x86: asus-wmi: Only notify kbd LED hw_change by fn-key pressed
Since commit
dbb3d78f61ba ("platform/x86: asus-wmi: Call led hw_changed
API on kbd brightness change"), asus-wmi directly changes the keyboard
LED brightness when the keyboard brightness keys are pressed,
raising the appropriate notification.
However, this notification was unintentionally also being raised during
boot and resume from suspend. This was resulting in userspace showing
the keyboard LED OSD on resume for no good reason.
Move the keyboard LED brightness changed notification
from kbd_led_update to the new kbd_led_set_by_kbd function which is only
called from the keyboard brightness function keys codepath.

platform/x86: Add Intel AtomISP2 dummy / power-management driver
The Image Signal Processor found on Cherry Trail devices is brought up in
D0 state on devices which have camera sensors attached to it. The ISP will
not enter D3 state again without some massaging of its registers beforehand
and the ISP not being in D3 state blocks the SoC from entering S0ix modes.
There was a driver for the ISP in drivers/staging but that got removed
again because it never worked. It does not seem likely that a real
driver for the ISP will be added to the mainline kernel anytime soon.
This commit adds a dummy driver which contains the necessary magic from
the staging driver to powerdown the ISP, so that Cherry Trail devices where
the ISP is used will properly use S0ix modes when suspended.
Together with other recent S0ix related fixes this allows S0ix modes to
be entered on e.g. a Chuwi Hi8 Pro and a HP x2 210.

This is also applicable to the platforms where the BIOS supports IPC1

firmware: dell_rbu: Make payload memory uncachable
The dell_rbu driver takes firmware update payloads and puts them in memory so
the system BIOS can find them after a reboot. This sometimes fails (though
rarely), because the memory containing the payload is in the CPU cache but
never gets written back to main memory before the system is rebooted (CPU
cache contents are lost on reboot).
With this patch, the payload memory will be changed to uncachable to ensure
that the payload is actually in main memory before the system is rebooted.

platform/x86: acerhdf: restructure to allow large BIOS table be __initconst
There is a table of Vendor/Model/Version {control data} in this driver,
but outside of the initial probe, the V/M/V is never used again, and
neither are any of the entries for platforms other than the one which
matches the running target.
By simply storing the {control data} for the matched platform, we can
mark the large table __initconst, which reduces the loaded driver size
by 20 percent.

This driver has two module parameters that allow an override of the

expect you to choose an entry from the existing list of supported

Without the source, such as in a binary distribution, the end user
does not have access to this information, thus rendering the two
module parameters essentially useless.
Add a module parameter that allows the end user to dump the list
of make/model/versions so that they can then pick one that most

"As it stands, memory_failure() gets thoroughly confused by dev_pagemap
backed mappings. The recovery code has specific enabling for several
possible page states and needs new enabling to handle poison in dax
mappings.
In order to support reliable reverse mapping of user space addresses:
1/ Add new locking in the memory_failure() rmap path to prevent races
that would typically be handled by the page lock.
2/ Since dev_pagemap pages are hidden from the page allocator and the
"compound page" accounting machinery, add a mechanism to determine
the size of the mapping that encompasses a given poisoned pfn.
3/ Given pmem errors can be repaired, change the speculatively
accessed poison protection, mce_unmap_kpfn(), to be reversible and
otherwise allow ongoing access from the kernel.
A side effect of this enabling is that MADV_HWPOISON becomes usable
for dax mappings, however the primary motivation is to allow the
system to survive userspace consumption of hardware-poison via dax.

mm/cow: don't bother write protecting already write-protected pages
This is not normally noticeable, but repeated forks are unnecessarily
expensive because they repeatedly dirty the parent page tables during
the page table copy operation.
It's trivial to just avoid write protecting the page table entry if it
was already not writable.
This patch was inspired by
https://bugzilla.kernel.org/show_bug.cgi?id=200447
which points to an ancient "waste time re-doing fork" issue in the
presence of lots of signals.
That bug was fixed by Eric Biederman's signal handling series
culminating in commit
c3ad2c3b02e9 ("signal: Don't restart fork when
signals come in"), but the unnecessary work for repeated forks is still
work just fixing, particularly since the fix is trivial.

iommu/rockchip: Move irq request past pm_runtime_enable
Enabling the interrupt early, before power has been applied to the
device, can result in an interrupt being delivered too early if:
- the IOMMU shares an interrupt with a VOP
- the VOP has a pending interrupt (after a kexec, for example)
In these conditions, we end-up taking the interrupt without
the IOMMU being ready to handle the interrupt (not powered on).
Moving the interrupt request past the pm_runtime_enable() call
makes sure we can at least access the IOMMU registers. Note that
this is only a partial fix, and that the VOP interrupt will still
be screaming until the VOP driver kicks in, which advocates for
a more synchronized interrupt enabling/disabling approach.
