Commit cfae58ed68 ("platform/x86: intel-vbtn: Only blacklist
SW_TABLET_MODE on the 9 / "Laptop" chasis-type") restored SW_TABLET_MODE
reporting on the HP stream x360 11 series on which it was previously broken
by commit de9647efea ("platform/x86: intel-vbtn: Only activate tablet
mode switch on 2-in-1's").
It turns out that enabling SW_TABLET_MODE reporting on devices with a
chassis-type of 10 ("Notebook") causes SW_TABLET_MODE to always report 1
at boot on the HP Pavilion 11 x360, which causes libinput to disable the
kbd and touchpad.
The HP Pavilion 11 x360's ACPI VGBS method sets bit 4 instead of bit 6 when
NOT in tablet mode at boot. Inspecting all the DSDTs in my DSDT collection
shows only one other model, the Medion E1239T ever setting bit 4 and it
always sets this together with bit 6.
So lets treat bit 4 as a second bit which when set indicates the device not
being in tablet-mode, as we already do for bit 6.
While at it also prefix all VGBS constant defines with "VGBS_".

Note this crash is present before any of the patches in this series, but
as explained below it is highly unlikely anyone is shipping a firmware that
causes it. Tests were done using an overriden SRAT.
On ARM64, the gic-v3 driver directly parses SRAT to locate GIC Interrupt
Translation Service (ITS) Affinity Structures. This is done much later
in the boot than the parses of SRAT which identify proximity domains.
As a result, an ITS placed in a proximity domain that is not defined by
another SRAT structure will result in a NUMA node that is not completely
configured and a crash.

ACPI 6.3 allows any set of Affinity Structures in SRAT to define a proximity
domain. However, as we do not see this crash, we can conclude that no
firmware is currently placing an ITS in a node that is separate from
those containing memory and / or processors.
We could modify the SRAT parsing behavior to identify the existence
of Proximity Domains unique to the ITS structures, and handle them as
a special case of a generic initiator (once support for those merges).
This patch avoids the complexity that would be needed to handle this corner
case, by not allowing the ITS entry parsing code to instantiate new NUMA
Nodes. If one is encountered that does not already exist, then NO_NUMA_NODE
is assigned and a warning printed just as if the value had been greater than
allowed NUMA Nodes.
"SRAT: Invalid NUMA node -1 in ITS affinity"
Whilst this does not provide the full flexibility allowed by ACPI,
it does fix the problem. We can revisit a more sophisticated solution if
needed by future platforms.
Change is simply to replace acpi_map_pxm_to_node with pxm_to_node reflecting
the fact a new mapping is not created.

acpi_get_node() calls acpi_get_pxm() to evaluate the _PXM AML method
for entries found in DSDT/SSDT. ACPI 6.3 sec 6.2.14 states
"_PXM evaluates to an integer that identifies a device as belonging to
a Proximity Domain defined in the System Resource Affinity Table (SRAT)."
Hence a _PXM method should not result in creation of a new NUMA node.
Before this patch, _PXM could result in partial instantiation of
NUMA node, missing elements such as zone lists. A call to
devm_kzalloc(), for example, results in a NULL pointer dereference.
This patch therefore replaces the acpi_map_pxm_to_node() with a call
to pxm_to_node().

While this function will only return an online node, it can have the side
effect of partially creating a new node. The existing comments suggest this
is intentional, but the usecases of this function are related to NFIT and
HMAT parsing, neither of which should be able to define new nodes.
One route by which the existing behaviour would cause a crash is to have a
_PXM entry in ACPI DSDT attempt to place a device within this partly
created proximity domain. A subsequent call to devm_kzalloc() or similar
would result in an attempt to allocate memory on a node for which zone
lists have not been set up and a NULL pointer dereference.
Prevent such cases by switching to pxm_to_node() within
acpi_map_pxm_to_online_node() which cannot cause a new node to be
partly created. If one would previously have been created we now
return NO_NUMA_NODE. Documentation updated to reflect this change.

Several ACPI static tables contain references to proximity domains.
ACPI 6.3 has clarified that only entries in SRAT may define a new
domain (sec 5.2.16).
Those tables described in the ACPI spec have additional clarifying text.
NFIT: Table 5-132,
"Integer that represents the proximity domain to which the memory
belongs. This number must match with corresponding entry in the
SRAT table."
HMAT: Table 5-145,
"... This number must match with the corresponding entry in the SRAT
table's processor affinity structure ... if the initiator is a processor,
or the Generic Initiator Affinity Structure if the initiator is a generic
initiator".
IORT and DMAR are defined by external specifications.
Intel Virtualization Technology for Directed I/O Rev 3.1 does not make any
explicit statements, but the general SRAT statement above will still apply.
https://software.intel.com/sites/default/files/managed/c5/15/vt-directed-io-spec.pdf
IO Remapping Table, Platform Design Document rev D, also makes not explicit
statement, but refers to ACPI SRAT table for more information and again the
generic SRAT statement above applies.
https://developer.arm.com/documentation/den0049/d/
In conclusion, any proximity domain specified in these tables, should be a
reference to a proximity domain also found in SRAT, and they should not be
able to instantiate a new domain. Hence we switch to pxm_to_node() which
will only return existing nodes.

IOMMU SNP support requires the completion wait write-back semaphore to be
implemented using a 4K-aligned page, where the page address is to be
programmed into the newly introduced MMIO base/range registers.
This new scheme uses a per-iommu atomic variable to store the current
semaphore value, which is incremented for every completion wait command.
Since this new scheme is also compatible with non-SNP mode,
generalize the driver to use 4K page for completion-wait semaphore in
both modes.

Commit 653055b9ac ("vhost-vdpa: support get/set backend features")
introduces two malfunction backend features ioctls:
1) the ioctls was blindly added to vring ioctl instead of vdpa device
ioctl
2) vhost_set_backend_features() was called when dev mutex has already
been held which will lead a deadlock
This patch fixes the above issues.
