Slim Bootloader(SBL) is a small open-source boot firmware,
designed for running on certain Intel platforms. SBL can be
thought-of as fulfilling the role of a minimal BIOS
implementation, i.e initializing the hardware and booting
Operating System.
Since SBL is not UEFI compliant, firmware update cannot be triggered
using standard UEFI runtime services. Further considering performance
impact, SBL doesn't look for a firmware update image on every reset
and does so only when firmware update signal is asserted.
SBL exposes an ACPI-WMI device which comes up in sysfs as
/sys/bus/wmi/44FADEB1xxx and this driver adds a
"firmware_update_request" device attribute. This attribute normally
has a value of 0 and userspace can signal SBL to update firmware,
on next reboot, by writing a value of 1 like:
echo 1 > /sys/bus/wmi/devices/44FADEB1xxx/firmware_update_request
This driver only implements a signaling mechanism, the actual firmware
update process and various details like firmware update image format,
firmware image location etc are defined by SBL and are not in the
scope of this driver.

When both CONFIG_DEBUG_FS and CONFIG_PM_SLEEP are disabled, the
functions that got moved out of the #ifdef section now cause
a warning:
drivers/platform/x86/intel_pmc_core.c:654:13: error: 'pmc_core_lpm_display' defined but not used [-Werror=unused-function]
654 | static void pmc_core_lpm_display(struct pmc_dev *pmcdev, struct device *dev,

617 | static void pmc_core_slps0_display(struct pmc_dev *pmcdev, struct device *dev,
| ^~~~~~~~~~~~~~~~~~~~~~
Rather than add even more #ifdefs here, remove them entirely and
let the compiler work it out, it can actually get rid of all the
debugfs calls without problems as long as the struct member is
there.
The two PM functions just need a __maybe_unused annotations to avoid
another warning instead of the #ifdef.

Intel Elkhart Lake exposes SCU/PMC as an ACPI device that only supports
IPC functionality so add a platform driver supporting it. Interrupt is
optional so we let intel_scu_ipc_probe() to decide based on the passed
platform data whether it uses interrupt or polling.

This adds dual fan control for the following models:
P50, P51, P52, P70, P71, P72, P1 gen1, P2 gen2, X1E gen1 and X1E gen2.
Both fans are controlled together as if they were a single fan.
Tested on an X1 Extreme Gen1, an X1 Extreme Gen2, and a P50.
The patch is defensive, it adds only specific supported machines, and falls
back to the old behavior if both fans cannot be controlled.
Background:
I tested the BIOS default behavior on my X1E gen2 and both fans are always
changed together. So rather than adding controls for each fan, this controls
both fans together as the BIOS would do.
This was inspired by a discussion on dual fan support for the thinkfan tool
(see link below). All BIOS IDs are taken from there. The X1E gen2 ID is
verified on my machine.
Thanks to GitHub users voidworker and civic9 for the earlier patches and
BIOS IDs, and to users peter-stoll and sassman for testing the patch on
their machines.

This driver only creates a bunch of platform devices sharing resources
belonging to the PMC device. This is pretty much what MFD subsystem is
for so move the driver there, renaming it to intel_pmc_bxt.c which
should be more clear what it is.
MFD subsystem provides nice helper APIs for subdevice creation so
convert the driver to use those. Unfortunately the ACPI device includes
separate resources for most of the subdevices so we cannot simply call
mfd_add_devices() to create all of them but instead we need to call it
separately for each device.
The new MFD driver continues to expose two sysfs attributes that allow
userspace to send IPC commands to the PMC/SCU to avoid breaking any
existing applications that may use these. Generally this is bad idea so
document this in the ABI documentation.

The current SCU IPC API has been operating on a single instance and
there has been no way to pin the providing module in place when the SCU
IPC is in use.
This implements a new API that takes the SCU IPC instance as first
parameter (NULL means the single instance is being used). The SCU IPC
instance can be retrieved by calling new function intel_scu_ipc_dev_get()
that take care of pinning the providing module in place as long as
intel_scu_ipc_dev_put() is not called.
The old API is updated to call the new API and is is left there in the
legacy API header to support the existing users that cannot be converted
easily.
Subsequent patches will convert most of the users over to the new API.

The SCU IPC functionality is usable outside of Intel MID devices. For
example modern Intel CPUs include the same thing but now it is called
PMC (Power Management Controller) instead of SCU. To make the IPC
available for those split the driver into core part (intel_scu_ipc.c)
and the SCU PCI driver part (intel_scu_pcidrv.c) which then calls the
former before it goes and creates rest of the SCU devices. The SCU IPC
will also register a new class that gets assigned to the device that is
created under the parent PCI device.
We also split the Kconfig symbols so that INTEL_SCU_IPC enables the SCU
IPC library and INTEL_SCU_PCI the SCU driver and convert the users
accordingly. While there remove default y from the INTEL_SCU_PCI symbol
as it is already selected by X86_INTEL_MID.

asus-nb-wmi does not add any extra functionality on these Asus
Transformer books. They have detachable keyboards, so the hotkeys are
send through a HID device (and handled by the hid-asus driver) and also
the rfkill functionality is not used on these devices.
Besides not adding any extra functionality, initializing the WMI interface
on these devices actually has a negative side-effect. For some reason
the \_SB.ATKD.INIT() function which asus_wmi_platform_init() calls drives
GPO2 (INT33FC:02) pin 8, which is connected to the front facing webcam LED,
high and there is no (WMI or other) interface to drive this low again
causing the LED to be permanently on, even during suspend.
This commit adds a blacklist of DMI system_ids on which not to load the
asus-nb-wmi and adds these Transformer books to this list. This fixes
the webcam LED being permanently on under Linux.

When remapping a mapping where a portion of a VMA is remapped
into another portion of the VMA it can cause the VMA to become
split. During the copy_vma operation the VMA can actually
be remerged if it's an anonymous VMA whose pages have not yet
been faulted. This isn't normally a problem because at the end
of the remap the original portion is unmapped causing it to
become split again.
However, MREMAP_DONTUNMAP leaves that original portion in place which
means that the VMA which was split and then remerged is not actually
split at the end of the mremap. This patch fixes a bug where
we don't detect that the VMAs got remerged and we end up
putting back VM_ACCOUNT on the next mapping which is completely
unreleated. When that next mapping is unmapped it results in
incorrectly unaccounting for the memory which was never accounted,
and eventually we will underflow on the memory comittment.
There is also another issue which is similar, we're currently
accouting for the number of pages in the new_vma but that's wrong.
We need to account for the length of the remap operation as that's
all that is being added. If there was a mapping already at that
location its comittment would have been adjusted as part of
the munmap at the start of the mremap.
A really simple repro can be seen in:

Pull scheduler fixes from Thomas Gleixner:
"Two fixes for the scheduler:
- Work around an uninitialized variable warning where GCC can't
figure it out.
- Allow 'isolcpus=' to skip unknown subparameters so that older
kernels work with the commandline of a newer kernel. Improve the
error output while at it"
