commit fca432e73db2bec0fdbfbf6d98d3ebcd5388a977 upstream.
The following sysfs entries are reading super block member directly,
which can have a different endian and cause wrong values:
- sys/fs/btrfs/<uuid>/nodesize
- sys/fs/btrfs/<uuid>/sectorsize
- sys/fs/btrfs/<uuid>/clone_alignment
Thankfully those values (nodesize and sectorsize) are always aligned
inside the btrfs_super_block, so it won't trigger unaligned read errors,
just endian problems.
Fix them by using the native cached members instead.

commit 49e1f0fd0d4cb03a16b8526c4e683e1958f71490 upstream.
Running i2c-detect currently produces an output akin to:
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: 08 -- 0a -- 0c -- 0e --

60: 60 -- 62 -- 64 -- 66 -- 68 -- 6a -- 6c -- 6e --
70: 70 -- 72 -- 74 -- 76 --
This happens because for an i2c_msg with a len of 0 the driver will
mark the transmission of the message as a success once the START has
been sent, without waiting for the devices on the bus to respond with an
ACK/NAK. Since i2cdetect seems to run in a tight loop over all addresses
the NAK is treated as part of the next test for the next address.
Delete the fast path that marks a message as complete when idev->msg_len
is zero after sending a START/RESTART since this isn't a valid scenario.

commit e0cec363197e41af870613e8e17b30bf0e3d41b5 upstream.
Compatible string "fsl,imx7d-i2c" is not exited at i2c-imx driver
compatible string table, at the result, "fsl,imx21-i2c" will be
matched, but it will cause erratum ERR007805 not be applied in fact.
So Add "fsl,imx7d-i2c" compatible string in i2c-imx driver to apply
the erratum ERR007805(https://www.nxp.com/docs/en/errata/IMX7DS_3N09P.pdf).
"
ERR007805 I2C: When the I2C clock speed is configured for 400 kHz,
the SCL low period violates the I2C spec of 1.3 uS min
Description: When the I2C module is programmed to operate at the
maximum clock speed of 400 kHz (as defined by the I2C spec), the SCL
clock low period violates the I2C spec of 1.3 uS min. The user must
reduce the clock speed to obtain the SCL low time to meet the 1.3us
I2C minimum required. This behavior means the SoC is not compliant
to the I2C spec at 400kHz.
Workaround: To meet the clock low period requirement in fast speed
mode, SCL must be configured to 384KHz or less.
"
"fsl,imx7d-i2c" already is documented in binding doc. This erratum
fix has been included in imx6_i2c_hwdata and it is the same in all
I.MX6/7/8, so just reuse it.

commit a60b990798eb17433d0283788280422b1bd94b18 upstream.
Alexandre observed a warning emitted from pci_msi_setup_msi_irqs() on a
RISCV platform which does not provide PCI/MSI support:
WARNING: CPU: 1 PID: 1 at drivers/pci/msi/msi.h:121 pci_msi_setup_msi_irqs+0x2c/0x32
__pci_enable_msix_range+0x30c/0x596
pci_msi_setup_msi_irqs+0x2c/0x32
pci_alloc_irq_vectors_affinity+0xb8/0xe2
RISCV uses hierarchical interrupt domains and correctly does not implement
the legacy fallback. The warning triggers from the legacy fallback stub.
That warning is bogus as the PCI/MSI layer knows whether a PCI/MSI parent
domain is associated with the device or not. There is a check for MSI-X,
which has a legacy assumption. But that legacy fallback assumption is only
valid when legacy support is enabled, but otherwise the check should simply
return -ENOTSUPP.
Loongarch tripped over the same problem and blindly enabled legacy support
without implementing the legacy fallbacks. There are weak implementations
which return an error, so the problem was papered over.
Correct pci_msi_domain_supports() to evaluate the legacy mode and add
the missing supported check into the MSI enable path to complete it.

Before commit:
f5d39b0208 ("freezer,sched: Rewrite core freezer logic")
the frozen task stat was reported as 'D' in cgroup v1.
However, after rewriting the core freezer logic, the frozen task stat is
reported as 'R'. This is confusing, especially when a task with stat of
'S' is frozen.
This bug can be reproduced with these steps:
$ cd /sys/fs/cgroup/freezer/
$ mkdir test
$ sleep 1000 &
[1] 739 // task whose stat is 'S'
$ echo 739 > test/cgroup.procs
$ echo FROZEN > test/freezer.state
$ ps -aux | grep 739
root 739 0.1 0.0 8376 1812 pts/0 R 10:56 0:00 sleep 1000
As shown above, a task whose stat is 'S' was changed to 'R' when it was
frozen.
To solve this regression, simply maintain the same reported state as
before the rewrite.

we can use the amdgpu structures directly.
This also avoids having the kfd_cu_info structures on

Commit 4ce6e2db00de ("virtio-blk: Ensure no requests in virtqueues before

PM callbacks. And the motivation is to drain inflight IOs before suspending.
block layer's queue freeze looks very handy, but it is also easy to cause
deadlock, such as, any attempt to call into bio_queue_enter() may run into
deadlock if the queue is frozen in current context. There are all kinds
of ->suspend() called in suspend context, so keeping queue frozen in the
whole suspend context isn't one good idea. And Marek reported lockdep
warning[1] caused by virtio-blk's freeze queue in virtblk_freeze().
[1] https://lore.kernel.org/linux-block/ca16370e-d646-4eee-b9cc-87277c89c43c@samsung.com/
Given the motivation is to drain in-flight IOs, it can be done by calling
freeze & unfreeze, meantime restore to previous behavior by keeping queue
quiesced during suspend.

The SH DAC audio driver uses the kmalloc'ed buffer as the main PCM
buffer, and the data is transferred via hrtimer callbacks manually
from there to the hardware. Meanwhile, some of its code are written
as if the buffer is on iomem and use the special helpers for the iomem
(e.g. copy_from_iter_toio() or memset_io()). Those are rather useless
and the standard helpers should be used.
Similarly, the PCM mmap callback is set to a special one with
snd_pcm_lib_mmap_iomem, but this is also nonsense, because SH
architecture doesn't support this function, hence it leads just to
NULL -- the fallback to the standard helper.
This patch replaces those special setups with the standard ones.
