commit ae1f7b93b52095be6776d0f34957b4f35dda44d9 upstream.
The IIO standard units are measured in kPa while the driver
is using hPa.
Apart from checking the userspace value itself, it is mentioned also
in the Bosch API [1] that the pressure value is in Pascal.

commit ab069ce125965a5e282f7b53b86aee76ab32975c upstream.
sdhci_check_ro() can call mmc_gpio_get_ro() while holding the sdhci
host->lock spinlock. That would be a problem if the GPIO access done by
mmc_gpio_get_ro() needed to sleep.
However, host->lock is not needed anyway. The mmc core ensures that host
operations do not race with each other, and asynchronous callbacks like the
interrupt handler, software timeouts, completion work etc, cannot affect
sdhci_check_ro().
So remove the locking.

commit fbd64f902b93fe9658b855b9892ae59ef6ea22b9 upstream.
mmc_of_parse() reads device property "wp-inverted" and sets
MMC_CAP2_RO_ACTIVE_HIGH if it is true. MMC_CAP2_RO_ACTIVE_HIGH is used
to invert a write-protect (AKA read-only) GPIO value.
sdhci_get_property() also reads "wp-inverted" and sets
SDHCI_QUIRK_INVERTED_WRITE_PROTECT which is used to invert the
write-protect value as well but also acts upon a value read out from the
SDHCI_PRESENT_STATE register.
Many drivers call both mmc_of_parse() and sdhci_get_property(),
so that both MMC_CAP2_RO_ACTIVE_HIGH and
SDHCI_QUIRK_INVERTED_WRITE_PROTECT will be set if the controller has
device property "wp-inverted".
Amend the logic in sdhci_check_ro() to allow for that possibility,
so that the write-protect value is not inverted twice.
Also do not invert the value if it is a negative error value. Note that
callers treat an error the same as not-write-protected, so the result is
functionally the same in that case.
Also do not invert the value if sdhci host operation ->get_ro() is used.
None of the users of that callback set SDHCI_QUIRK_INVERTED_WRITE_PROTECT
directly or indirectly, but two do call mmc_gpio_get_ro(), so leave it to
them to deal with that if they ever set SDHCI_QUIRK_INVERTED_WRITE_PROTECT
in the future.

[ Upstream commit 9919cce62f68e6ab68dc2a975b5dc670f8ca7d40 ]
linehandle_set_config() behaves badly when direction is not set.
The configuration validation is borrowed from linehandle_create(), where,
to verify the intent of the user, the direction must be set to in order
to effect a change to the electrical configuration of a line. But, when
applied to reconfiguration, that validation does not allow for the unset
direction case, making it possible to clear flags set previously without
specifying the line direction.
Adding to the inconsistency, those changes are not immediately applied by
linehandle_set_config(), but will take effect when the line value is next
get or set.
For example, by requesting a configuration with no flags set, an output
line with GPIOHANDLE_REQUEST_ACTIVE_LOW and GPIOHANDLE_REQUEST_OPEN_DRAIN
requested could have those flags cleared, inverting the sense of the line
and changing the line drive to push-pull on the next line value set.
Ensure the intent of the user by disallowing configurations which do not
have direction set, returning an error to userspace to indicate that the
configuration is invalid.
And, for clarity, use lflags, a local copy of gcnf.flags, throughout when
dealing with the requested flags, rather than a mixture of both.

This is an effort to get rid of all multiplications from allocation
functions in order to prevent integer overflows [1] [2].
In this case, the memory allocated to store RADEONFB_CONN_LIMIT pointers
to "drm_connector" structures can be avoided. This is because this
memory area is never accessed.
Also, in the kzalloc function, it is preferred to use sizeof(*pointer)
instead of sizeof(type) due to the type of the variable can change and
one needs not change the former (unlike the latter).
At the same time take advantage to remove the "#if 0" block, the code
where the removed memory area was accessed, and the RADEONFB_CONN_LIMIT
constant due to now is never used.

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.

Dell Inspiron 14 2-in-1 has two ACPI nodes under GPP1 both with _ADR of
0, both without _HID. It's ambiguous which the kernel should take, but
it seems to take "DEV0". Unfortunately "DEV0" is missing the device
property `StorageD3Enable` which is present on "NVME".
To avoid this causing problems for suspend, add a quirk for this system
to behave like `StorageD3Enable` property was found.

[ Upstream commit 6485fc18faa01e8845b1e5bb55118e633f84d1f2 ]
AMD systems from Renoir and Lucienne require that the NVME controller
is put into D3 over a Modern Standby / suspend-to-idle
cycle. This is "typically" accomplished using the `StorageD3Enable`
property in the _DSD, but this property was introduced after many
of these systems launched and most OEM systems don't have it in
their BIOS.
On AMD Renoir without these drives going into D3 over suspend-to-idle
the resume will fail with the NVME controller being reset and a trace
like this in the kernel logs:
```
[ 83.556118] nvme nvme0: I/O 161 QID 2 timeout, aborting
[ 83.556178] nvme nvme0: I/O 162 QID 2 timeout, aborting

```
The Microsoft documentation for StorageD3Enable mentioned that Windows has
a hardcoded allowlist for D3 support, which was used for these platforms.
Introduce quirks to hardcode them for Linux as well.
As this property is now "standardized", OEM systems using AMD Cezanne and
newer APU's have adopted this property, and quirks like this should not be
necessary.

[ Upstream commit c71e3a5cffd5309d7f84444df03d5b72600cc417 ]
An issue was found on the RTL8125b when transmitting small fragmented
packets, whereby invalid entries were inserted into the transmit ring
buffer, subsequently leading to calls to dma_unmap_single() with a null
address.
This was caused by rtl8169_start_xmit() not noticing changes to nr_frags
which may occur when small packets are padded (to work around hardware
quirks) in rtl8169_tso_csum_v2().
To fix this, postpone inspecting nr_frags until after any padding has been
applied.

We can simplify the for() condition and eliminate variable tx_left.
The change also considers that tp->cur_tx may be incremented by a
racing rtl8169_start_xmit().
In addition replace the write to tp->dirty_tx and the following
smp_mb() with an equivalent call to smp_store_mb(). This implicitly
adds a WRITE_ONCE() to the write.

tp->dirty_tx isn't changed outside rtl_tx(). Therefore I see no need
to guarantee a specific order of reading tp->dirty_tx and tp->cur_tx.
Having said that we can remove the memory barrier.
In addition use READ_ONCE() when reading tp->cur_tx because it can
change in parallel to rtl_tx().

btree_iter is used in two ways: either allocated on the stack with a
fixed size MAX_BSETS, or from a mempool with a dynamic size based on the
specific cache set. Previously, the struct had a fixed-length array of
size MAX_BSETS which was indexed out-of-bounds for the dynamically-sized
iterators, which causes UBSAN to complain.
This patch uses the same approach as in bcachefs's sort_iter and splits
the iterator into a btree_iter with a flexible array member and a
btree_iter_stack which embeds a btree_iter as well as a fixed-length
data array.

_rtl92c_phy_get_rightchnlplace expects an array which includes all the

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.
