[ Upstream commit e79a10652bbd320649da705ca1ea0c04351af403 ]
A Rembrandt-based HP thin client is reported to have problems where
the NVME disk isn't present after resume from s2idle.
This is because the NVME disk wasn't put into D3 at suspend, and
that happened because the StorageD3Enable _DSD was missing in the BIOS.
As AMD's architecture requires that the NVME is in D3 for s2idle, adjust
the criteria for force_storage_d3 to match *all* Zen SoCs when the FADT
advertises low power idle support.
This will ensure that any future products with this BIOS deficiency don't
need to be added to the allow list of overrides.

Picasso was the first APU that introduced s2idle support from AMD,
and it was predating before vendors started to use `StorageD3Enable`
in their firmware.
Windows doesn't have problems with this hardware and NVME so it was
likely on the list of hardcoded CPUs to use this behavior in Windows.
Add it to the list for Linux to avoid NVME resume issues.

[ Upstream commit a83e1385b780d41307433ddbc86e3c528db031f0 ]
Undo the modifications made in commit d410ee5109a1 ("ACPICA: avoid
"Info: mapping multiple BARs. Your kernel is fine.""). The initial
purpose of this commit was to stop memory mappings for operation
regions from overlapping page boundaries, as it can trigger warnings
if different page attributes are present.
However, it was found that when this situation arises, mapping
continues until the boundary's end, but there is still an attempt to
read/write the entire length of the map, leading to a NULL pointer
deference. For example, if a four-byte mapping request is made but
only one byte is mapped because it hits the current page boundary's
end, a four-byte read/write attempt is still made, resulting in a NULL
pointer deference.
Instead, map the entire length, as the ACPI specification does not
mandate that it must be within the same page boundary. It is
permissible for it to be mapped across different regions.

commit 2f4a4d63a193 ("ACPI: CPPC: Use access_width over bit_width for system
memory accesses") modified cpc_read()/cpc_write() to use access_width to
read CPC registers.
However, for PCC registers the access width field in the ACPI register
macro specifies the PCC subspace ID. For non-zero PCC subspace ID it is
incorrectly treated as access width. This causes errors when reading
from PCC registers in the CPPC driver.
For PCC registers, base the size of read/write on the bit width field.
The debug message in cpc_read()/cpc_write() is updated to print relevant
information for the address space type used to read the register.

originally put in place to work around a s2idle failure on this platform
where the NVMe device was inaccessible upon resume.
After extended testing, we found that the firmware's implementation of S3
is buggy and intermittently fails to wake up the system. We need to revert
to s2idle mode.
The NVMe issue has now been solved more precisely in the commit titled
"PCI: Disable D3cold on Asus B1400 PCI-NVMe bridge"

Instead, use access_width to determine the size and use the offset and
width to shift and mask the bits to read/write out. Make sure to add a
check for system memory since pcc redefines the access_width to
subspace id.
If access_width is not set, then fall back to using bit_width.

[ Upstream commit a70297d2213253853e95f5b49651f924990c6d3b ]
There are two major types of uncorrected recoverable (UCR) errors :
- Synchronous error: The error is detected and raised at the point of
the consumption in the execution flow, e.g. when a CPU tries to
access a poisoned cache line. The CPU will take a synchronous error
exception such as Synchronous External Abort (SEA) on Arm64 and
Machine Check Exception (MCE) on X86. OS requires to take action (for
example, offline failure page/kill failure thread) to recover this
uncorrectable error.
- Asynchronous error: The error is detected out of processor execution
context, e.g. when an error is detected by a background scrubber.
Some data in the memory are corrupted. But the data have not been
consumed. OS is optional to take action to recover this uncorrectable
error.
When APEI firmware first is enabled, a platform may describe one error
source for the handling of synchronous errors (e.g. MCE or SEA notification
), or for handling asynchronous errors (e.g. SCI or External Interrupt
notification). In other words, we can distinguish synchronous errors by
APEI notification. For synchronous errors, kernel will kill the current
process which accessing the poisoned page by sending SIGBUS with
BUS_MCEERR_AR. In addition, for asynchronous errors, kernel will notify the
process who owns the poisoned page by sending SIGBUS with BUS_MCEERR_AO in
early kill mode. However, the GHES driver always sets mf_flags to 0 so that
all synchronous errors are handled as asynchronous errors in memory failure.
To this end, set memory failure flags as MF_ACTION_REQUIRED on synchronous
events.

snprintf() does not return negative values on error.
To know if the buffer was too small, the returned value needs to be
compared with the length of the passed buffer. If it is greater or
equal, the output has been truncated, so add checks for the truncation
to create_pnp_modalias() and create_of_modalias(). Also make them
return -ENOMEM in that case, as they already do that elsewhere.
Moreover, the remaining size of the buffer used by snprintf() needs to
be updated after the first write to avoid out-of-bounds access as
already done correctly in create_pnp_modalias(), but not in
create_of_modalias(), so change the latter accordingly.
