Drivers like thinkpad_acpi and ideapad_laptop call the
platform_profile_notify() helper when the profile is changed by hardware
(the embedded-controller/EC) in response to an EC handled hotkey.
This allows userspace to monitor for such changes by polling for POLLPRI
on the platform_profile sysfs file. But the profile can also be changed
underneath a userspace program monitoring it by anonther userspace program
storing a new value.
Add a sysfs_notify() call to platform_profile_store(), so that userspace
programs monitoring for changes also get notified in this case.
Also update the documentation to document that POLLPRI polling can be
used to watch for changes.

Pull libnvdimm fixes from Dan Williams:
"A couple of fixes for long standing bugs, a warning fixup, and some
miscellaneous dax cleanups.
The bugs were recently found due to new platforms looking to use the
ACPI NFIT "virtual" device definition, and new error injection
capabilities to trigger error responses to label area requests. Ira's
cleanups have been long pending, I neglected to send them earlier, and
see no harm in including them now. This has all appeared in -next with
no reported issues.
Summary:
- Fix support for NFIT "virtual" ranges (BIOS-defined memory disks)
- Fix recovery from failed label storage areas on NVDIMM devices
- Miscellaneous cleanups from Ira's investigation of
dax_direct_access paths preparing for stray-write protection"

ACPI: NFIT: Fix support for virtual SPA ranges
dax: Ensure errno is returned from dax_direct_access
fs/dax: Clarify nr_pages to dax_direct_access()
fs/fuse: Remove unneeded kaddr parameter
Fix the NFIT parsing code to treat a 0 index in a SPA Range Structure as
a special case and not match Region Mapping Structures that use 0 to
indicate that they are not mapped. Without this fix some platform BIOS
descriptions of "virtual disk" ranges do not result in the pmem driver
attaching to the range.
Details:
In addition to typical persistent memory ranges, the ACPI NFIT may also
convey "virtual" ranges. These ranges are indicated by a UUID in the SPA
Range Structure of UUID_VOLATILE_VIRTUAL_DISK, UUID_VOLATILE_VIRTUAL_CD,
UUID_PERSISTENT_VIRTUAL_DISK, or UUID_PERSISTENT_VIRTUAL_CD. The
critical difference between virtual ranges and UUID_PERSISTENT_MEMORY,
is that virtual do not support associations with Region Mapping
Structures. For this reason the "index" value of virtual SPA Range
Structures is allowed to be 0. If a platform BIOS decides to represent
NVDIMMs with disconnected "Region Mapping Structures" (range-index ==
0), the kernel may falsely associate them with standalone ranges where
the "SPA Range Structure Index" is also zero. When this happens the
driver may falsely require labels where "virtual disks" are expected to
be label-less. I.e. "label-less" is where the namespace-range ==
region-range and the pmem driver attaches with no user action to create
a namespace.

The current assumption that methods to read PCH FIVR attributes will
return integer, is not correct. There is no good way to return integer
as negative numbers are also valid.
These read methods return a package of integers. The first integer returns
status, which is 0 on success and any other value for failure. When the
returned status is zero, then the second integer returns the actual value.
This change fixes this issue by replacing acpi_evaluate_integer() with
acpi_evaluate_object() and use acpi_extract_package() to extract results.

The I2C-bus to the XPower AXP288 is shared between the Linux kernel and
the SoCs P-Unit. The P-Unit has a semaphore which the kernel must "lock"
before it may use the bus and while the kernel holds the semaphore the CPU
and GPU power-states must not be changed otherwise the system will freeze.
This is a complex process, which is quite expensive. This is all done by
iosf_mbi_block_punit_i2c_access(). To ensure that no unguarded I2C-bus
accesses happen, iosf_mbi_block_punit_i2c_access() gets called by the
I2C-bus-driver for every I2C transfer. Because this is so expensive it
is allowed to call iosf_mbi_block_punit_i2c_access() in a nested
fashion, so that higher-level code which does multiple I2C-transfers can
call it once for a group of transfers, turning the calls done by the
I2C-bus-driver into no-ops.
The default exec_mipi_pmic_seq_element implementation from
drivers/acpi/pmic/intel_pmic.c does a regmap_update_bits() call and
the involved registers are typically marked as volatile in the regmap,
so this leads to 2 I2C-bus accesses.
Add a XPower AXP288 specific implementation of exec_mipi_pmic_seq_element
which calls iosf_mbi_block_punit_i2c_access() calls before the
regmap_update_bits() call to avoid having to do the whole expensive
acquire P-Unit semaphore dance twice.

When using s2idle on a variety of AMD notebook systems, they are
experiencing spurious events that the EC or SMU are in the wrong
state leading to a hard time waking up or higher than expected
power consumption.
These events only occur when the EC GPE is inadvertently set as a wakeup
source. Originally the EC GPE was only set as a wakeup source when using
the intel-vbtn or intel-hid drivers in commit 10a08fd65e ("ACPI: PM:
Set up EC GPE for system wakeup from drivers that need it") but during
testing a reporter discovered that this was not enough for their ASUS
Zenbook UX430UNR/i7-8550U to wakeup by lid event or keypress.
Marking the EC GPE for wakeup universally resolved this for that
reporter in commit b90ff3554a ("ACPI: PM: s2idle: Always set up EC GPE
for system wakeup").
However this behavior has lead to a number of problems:
* On both Lenovo T14 and P14s the keyboard wakeup doesn't work, and
sometimes the power button event doesn't work.
* On HP 635 G7 detaching or attaching AC during suspend will cause
the system not to wakeup
* On Asus vivobook to prevent detaching AC causing resume problems
* On Lenovo 14ARE05 to prevent detaching AC causing resume problems
* On HP ENVY x360 to prevent detaching AC causing resume problems
As there may be other Intel systems besides ASUS Zenbook UX430UNR/i7-8550U
that don't use intel-vbtn or intel-hid, avoid these problems by only
universally marking the EC GPE wakesource on non-AMD systems.

The Dell Vostro 3350 ACPI video-bus device reports spurious
ACPI_VIDEO_NOTIFY_CYCLE events resulting in spurious KEY_SWITCHVIDEOMODE
events being reported to userspace (and causing trouble there).
Add a quirk setting the report_key_events mask to
REPORT_BRIGHTNESS_KEY_EVENTS so that the ACPI_VIDEO_NOTIFY_CYCLE
events will be ignored, while still reporting brightness up/down
hotkey-presses to userspace normally.

In function amba_handler_attach(), dev->res.name is initialized by
amba_device_alloc. But when address_found is false, dev->res.name is
assigned to null value, which leads to wrong resource name display in
/proc/iomem, "<BAD>" is seen for those resources.

The ACPI Virtual I/O Translation Table describes topology of
para-virtual platforms, similarly to vendor tables DMAR, IVRS and IORT.
For now it describes the relation between virtio-iommu and the endpoints
it manages.
Three steps are needed to configure DMA of endpoints:
(1) acpi_viot_init(): parse the VIOT table, find or create the fwnode
associated to each vIOMMU device. This needs to happen after
acpi_scan_init(), because it relies on the struct device and their
fwnode to be available.
(2) When probing the vIOMMU device, the driver registers its IOMMU ops
within the IOMMU subsystem. This step doesn't require any
intervention from the VIOT driver.
(3) viot_iommu_configure(): before binding the endpoint to a driver,
find the associated IOMMU ops. Register them, along with the
endpoint ID, into the device's iommu_fwspec.
If step (3) happens before step (2), it is deferred until the IOMMU is
initialized, then retried.
