Currently connect/disconnect of USB cable calls afunc_bind and
eventually increments the bNumEndpoints. Performing multiple
plugin/plugout will increment bNumEndpoints incorrectly, and on
the next plug-in it leads to invalid configuration of descriptor
and hence enumeration fails.
Fix this by resetting the value of bNumEndpoints to 1 on every
afunc_bind call.

My last commit to fix profile mode displays on AMD platforms caused
an issue on Intel platforms - sorry!
In it I was reading the current functional mode (MMC, PSC, AMT) from
the BIOS but didn't account for the fact that on some of our Intel
platforms I use a different API which returns just the profile and not
the functional mode.
This commit fixes it so that on Intel platforms it knows the functional
mode is always MMC.
I also fixed a potential problem that a platform may try to set the mode
for both MMC and PSC - which was incorrect.
Tested on X1 Carbon 9 (Intel) and Z13 (AMD).

SysMMU v7 has a bit different registers for getting the fault info:
- there is one single register (MMU_FAULT_VA) to get the fault address
- fault access type (R/W) can be read from MMU_FAULT_TRANS_INFO
register now
- interrupt status register has different bits w.r.t. previous SysMMU
versions
- VM and non-VM layouts have different register addresses
Add correct fault handling implementation for SysMMU v7, according to
all mentioned differences. Only VID #0 (default) is handled, as VM
domains support is not implemented yet.

Fault info obtaining is implemented for SysMMU v1..v5 in a very hardware
specific way, as it relies on:
- interrupt bits being tied to read or write access
- having separate registers for the fault address w.r.t. AR/AW ops
Newer SysMMU versions (like SysMMU v7) have different way of providing
the fault info via registers:
- the transaction type (read or write) should be read from the
register (instead of hard-coding it w.r.t. corresponding interrupt
status bit)
- there is only one single register for storing the fault address
Because of that, it is not possible to add newer SysMMU support into
existing paradigm. Also it's not very effective performance-wise:
- checking SysMMU version in ISR each time is not necessary
- performing linear search to find the fault info by interrupt bit can
be replaced with a single lookup operation
Pave the way for adding support for new SysMMU versions by abstracting
the getting of fault info in ISR. While at it, do some related style
cleanups as well.
This is mostly a refactoring patch, but there are some minor functional
changes:
- fault message format is a bit different; now instead of AR/AW
prefixes for the fault's name, the request direction is printed as
[READ]/[WRITE]. It has to be done to prepare an abstraction for
SysMMU v7 support
- don't panic on unknown interrupts; print corresponding message and
continue
- if fault wasn't recovered, panic with some sane message instead of
just doing BUG_ON()
The whole fault message looks like this now:
[READ] PAGE FAULT occurred at 0x12341000

Merge patch-set from Jason:
"Let iommufd charge IOPTE allocations to the memory cgroup"
Description:
IOMMUFD follows the same design as KVM and uses memory cgroups to limit
the amount of kernel memory a iommufd file descriptor can pin down. The
various internal data structures already use GFP_KERNEL_ACCOUNT to charge
its own memory.
However, one of the biggest consumers of kernel memory is the IOPTEs
stored under the iommu_domain and these allocations are not tracked.
This series is the first step in fixing it.
The iommu driver contract already includes a 'gfp' argument to the
map_pages op, allowing iommufd to specify GFP_KERNEL_ACCOUNT and then
having the driver allocate the IOPTE tables with that flag will capture a
significant amount of the allocations.
Update the iommu_map() API to pass in the GFP argument, and fix all call
sites. Replace iommu_map_atomic().
Audit the "enterprise" iommu drivers to make sure they do the right thing.
Intel and S390 ignore the GFP argument and always use GFP_ATOMIC. This is
problematic for iommufd anyhow, so fix it. AMD and ARM SMMUv2/3 are
already correct.
A follow up series will be needed to capture the allocations made when the
iommu_domain itself is allocated, which will complete the job.

This function does an allocation of a buffer to return to the caller and
then goes on to allocate some internal memory, eg the scatterlist and
IOPTEs.
Instead of hard wiring GFP_KERNEL and a wrong GFP_ATOMIC, continue to use
the passed in gfp flags for all of the allocations. Clear the zone and
policy bits that are only relevant for the buffer allocation before
re-using them for internal allocations.
Auditing says this is never called from an atomic context, so the
GFP_ATOMIC is the incorrect flag.

Commit a286ba738714 ("ice: reorder PF/representor devlink

a corner case issue in the case of ice_register_netdev()
failing. In that case, the driver would end up calling
ice_devlink_destroy_pf_port() twice.
Additionally, it makes no sense to tie creation of the devlink
PF port to the creation of the netdev so separate out the
code to create/destroy the devlink PF port from the netdev
code. This makes it a cleaner interface.

Trip temperatures are read using ACPI methods and stored in the memory
during zone initializtion and when the firmware sends a notification for
change. This trip temperature is returned when the thermal core calls via
callback get_trip_temp().
But it is possible that while updating the memory copy of the trips when
the firmware sends a notification for change, thermal core is reading the
trip temperature via the callback get_trip_temp(). This may return invalid
trip temperature.
To address this add a mutex to protect the invalid temperature reads in
the callback get_trip_temp() and int340x_thermal_read_trips().

Commit a10b21532574 ("media: vb2: add (un)prepare_streaming queue ops") moved
up the q->streaming = 1 assignment to before the call to vb2_start_streaming().
This does make sense since q->streaming indicates that VIDIOC_STREAMON is called,
and the call to start_streaming happens either at that time or later if
q->min_buffers_needed > 0. So q->streaming should be 1 before start_streaming
is called.
However, it turned out that some drivers use vb2_is_streaming() in buf_queue,
and if q->min_buffers_needed == 0, then that will now return true instead of
false.
So for the time being revert to the original behavior.

Some apple laptop models have an ACPI device with a HID of APP000B
and that device has an IO resource (so it does not describe the new
unsupported MMIO based gmux type), but there actually is no gmux
in the laptop at all.
The gmux_probe() function of the actual apple-gmux driver has code
to detect this, this code has been factored out into a new
apple_gmux_detect() helper in apple-gmux.h.
Use this new function to fix acpi_video_get_backlight_type() wrongly

Add a new (static inline) apple_gmux_detect() helper to apple-gmux.h
which can be used for gmux detection instead of apple_gmux_present().
The latter is not really reliable since an ACPI device with a HID
of APP000B is present on some devices without a gmux at all, as well
as on devices with a newer (unsupported) MMIO based gmux model.
This causes apple_gmux_present() to return false-positives on
a number of different Apple laptop models.
This new helper uses the same probing as the actual apple-gmux
driver, so that it does not return false positives.
To avoid code duplication the gmux_probe() function of the actual
driver is also moved over to using the new apple_gmux_detect() helper.
This avoids false positives (vs _HID + IO region detection) on:

This is a preparation patch for adding a new static inline
apple_gmux_detect() helper which actually checks a supported
gmux is present, rather then only checking an ACPI device with
the HID is there as apple_gmux_present() does.

firmware and have workarounds in AMD PMC driver.
To allow them to bypass these workarounds, introduce a module

By default when the system is configured for low power idle in the FADT
the keyboard is set up as a wake source. This matches the behavior that
Windows uses for Modern Standby as well.
It has been reported that a variety of AMD based designs there are
spurious wakeups are happening where two IRQ sources are active.
For example:
```
PM: Triggering wakeup from IRQ 9
PM: Triggering wakeup from IRQ 1
```
In these designs IRQ 9 is the ACPI SCI and IRQ 1 is the keyboard.
One way to trigger this problem is to suspend the laptop and then unplug
the AC adapter. The SOC will be in a hardware sleep state and plugging
in the AC adapter returns control to the kernel's s2idle loop.
Normally if just IRQ 9 was active the s2idle loop would advance any EC
transactions and no other IRQ being active would cause the s2idle loop
to put the SOC back into hardware sleep state.
When this bug occurred IRQ 1 is also active even if no keyboard activity
occurred. This causes the s2idle loop to break and the system to wake.
This is a platform firmware bug triggering IRQ1 without keyboard activity.
This occurs in Windows as well, but Windows will enter "SW DRIPS" and
then with no activity enters back into "HW DRIPS" (hardware sleep state).
This issue affects Renoir, Lucienne, Cezanne, and Barcelo platforms. It
does not happen on newer systems such as Mendocino or Rembrandt.
It's been fixed in newer platform firmware. To avoid triggering the bug
on older systems check the SMU F/W version and adjust the policy at suspend
time for s2idle wakeup from keyboard on these systems. A lot of thought
and experimentation has been given around the timing of disabling IRQ1,
and to make it work the "suspend" PM callback is restored.

Commit 1ea0d3b46798 ("platform/x86: asus-wmi: Simplify tablet-mode-switch
handling") unified the asus-wmi tablet-switch handling, but it did not take
into account that the value returned for the kbd_dock_devid WMI method is
inverted where as the other ones are not inverted.
This causes asus-wmi to report an inverted tablet-switch state for devices
which use the kbd_dock_devid, which causes libinput to ignore touchpad
events while the affected T10x model 2-in-1s are docked.
Add inverting of the return value in the kbd_dock_devid case to fix this.

Add support to map the "HP Omen Key" to KEY_PROG2. Laptops in the HP
Omen Series open the HP Omen Command Center application on windows. But,
on linux it fails with the following message from the hp-wmi driver:
[ 5143.415714] hp_wmi: Unknown event_id - 29 - 0x21a5
Also adds support to map Fn+Esc to KEY_FN_ESC. This currently throws the
following message on the hp-wmi driver:

The DRM fbdev emulation layer sets the struct fb_info .fbdefio field to
a struct fb_deferred_io pointer, that is shared across all drivers that
use the generic drm_fbdev_generic_setup() helper function.
It is a problem because the fbdev core deferred I/O logic assumes that
the struct fb_deferred_io data is not shared between devices, and it's
stored there state such as the list of pages touched and a mutex that
is use to synchronize between the fb_deferred_io_track_page() function
that track the dirty pages and fb_deferred_io_work() workqueue handler
doing the actual deferred I/O.
The latter can lead to the following error, since it may happen that two
drivers are probed and then one is removed, which causes the mutex bo be
destroyed and not existing anymore by the time the other driver tries to
grab it for the fbdev deferred I/O logic:

Starting with commit eee16b147121 ("net: dsa: microchip: perform the
compatibility check for dev probed"), the KSZ switch driver now bails
out if it thinks the DT compatible doesn't match the actual chip ID
read back from the hardware:
ksz9477-switch 1-005f: Device tree specifies chip KSZ9893 but found
KSZ8563, please fix it!
For the KSZ8563, which used ksz_switch_chips[KSZ9893], this was fine
at first, because it indeed shares the same chip id as the KSZ9893.
Commit b44908095612 ("net: dsa: microchip: add separate struct
ksz_chip_data for KSZ8563 chip") started differentiating KSZ9893
compatible chips by consulting the 0x1F register. The resulting breakage
was fixed for the SPI driver in the same commit by introducing the
appropriate ksz_switch_chips[KSZ8563], but not for the I2C driver.
Fix this for I2C-connected KSZ8563 now to get it probing again.
