Support for booting the iMX remoteprocs using MMIO, instead of SMCCC is
added. The iMX driver is also extended to support delivering interrupts
from an arbitrary number of vdev.
Support is added to the TI PRU driver, to allow GPMUX to be controlled
from DeviceTree.
The Qualcomm coredump collector is extended to fall back to generating a
full coredump, in the case that the loaded firmware doesn't support
generating minidump. The overly terse MD abbreviation of "MINIDUMP" is
expanded, to make the code easier on the eye.
The list of Qualcomm Sensor Low Power Island (SLPI) instances supported
is cleaned up, and SDM845 is added. SDM630/636/660 support for the modem
subsystem (mss) is added.
All the Qualcomm drivers are transitioned to of_reserved_mem_lookup()
instead of open coding the resolution of reserved-memory regions, to
gain handling of error cases. A couple of drivers are transitioned to
use devm_platform_ioremap_resource_byname().
The stm32 remoteproc driver's PM operations are updated to modern
macros, to avoid the "unused variable"-warning in some configurations.
Drivers are transitioned away from directly including of_device.h.

a lot of developers were on holidays (including myself) it was a good

backed me up when I was on a four week hiatus. This is also the reason
that some patches were commited later than ideal.

In current packed virtqueue implementation, the avail_wrap_counter won't
flip, in the case when the driver supplies a descriptor chain with a
length equals to the queue size; total_sg == vq->packed.vring.num.
Let’s assume the following situation:
vq->packed.vring.num=4
vq->packed.next_avail_idx: 1
vq->packed.avail_wrap_counter: 0
Then the driver adds a descriptor chain containing 4 descriptors.
We expect the following result with avail_wrap_counter flipped:
vq->packed.next_avail_idx: 1
vq->packed.avail_wrap_counter: 1
But, the current implementation gives the following result:
vq->packed.next_avail_idx: 1
vq->packed.avail_wrap_counter: 0
To reproduce the bug, you can set a packed queue size as small as
possible, so that the driver is more likely to provide a descriptor
chain with a length equal to the packed queue size. For example, in
qemu run following commands:
sudo qemu-system-x86_64 \
-enable-kvm \
-nographic \
-kernel "path/to/kernel_image" \
-m 1G \
-drive file="path/to/rootfs",if=none,id=disk \
-device virtio-blk,drive=disk \
-drive file="path/to/disk_image",if=none,id=rwdisk \
-device virtio-blk,drive=rwdisk,packed=on,queue-size=4,\
indirect_desc=off \
-append "console=ttyS0 root=/dev/vda rw init=/bin/bash"
Inside the VM, create a directory and mount the rwdisk device on it. The
rwdisk will hang and mount operation will not complete.
This commit fixes the wrap counter error by flipping the
packed.avail_wrap_counter, when start of descriptor chain equals to the
end of descriptor chain (head == i).

We try to build affinity mask via create_affinity_masks()
unconditionally which may lead several issues:
- the affinity mask is not used for parent without affinity support
(only VDUSE support the affinity now)
- the logic of create_affinity_masks() might not work for devices
other than block. For example it's not rare in the networking device
where the number of queues could exceed the number of CPUs. Such
case breaks the current affinity logic which is based on
group_cpus_evenly() who assumes the number of CPUs are not less than
the number of groups. This can trigger a warning[1]:
if (ret >= 0)
WARN_ON(nr_present + nr_others < numgrps);
Fixing this by only build the affinity masks only when
- Driver passes affinity descriptor, driver like virtio-blk can make
sure to limit the number of queues when it exceeds the number of CPUs
- Parent support affinity setting config ops
This help to avoid the warning. More optimizations could be done on
top.

Currently, the virtio core will perform a dma operation for each
buffer. Although, the same page may be operated multiple times.
This patch, the driver does the dma operation and manages the dma
address based the feature premapped of virtio core.
This way, we can perform only one dma operation for the pages of the
alloc frag. This is beneficial for the iommu device.

Now we add a case where we skip dma unmap, the vq->premapped is true.
We can't just rely on use_dma_api to determine whether to skip the dma
operation. For convenience, I introduced the "do_unmap". By default, it
is the same as use_dma_api. If the driver is configured with premapped,
then do_unmap is false.
So as long as do_unmap is false, for addr of desc, we should skip dma
unmap operation.

In this cycle, we don't have a highlighted feature enhancement, but mostly
have fixed issues mainly in two parts: 1) zoned block device, 2) compression
support. For zoned block device, we've tried to improve the power-off recovery
flow as much as possible. For compression, we found some corner cases caused by
wrong compression policy and logics. Other than them, there were some reverts
and stat corrections.
Bug fix:
- use finish zone command when closing a zone
- check zone type before sending async reset zone command
- fix to assign compress_level for lz4 correctly
- fix error path of f2fs_submit_page_read()
- don't {,de}compress non-full cluster
- send small discard commands during checkpoint back
- flush inode if atomic file is aborted
- correct to account gc/cp stats
And, there are minor bug fixes, avoiding false lockdep warning, and clean-ups.

Commit bde5f6bc68db ("kmemleak: add scheduling point to kmemleak_scan()")
added a cond_resched() call to the struct page scanning loop to prevent
soft lockup from happening. However, soft lockup can still happen in that
loop in some corner cases when the pages that satisfy the "!(pfn & 63)"
check are skipped for some reasons.
Fix this corner case by moving up the cond_resched() check so that it will
be called every 64 pages unconditionally.

In the past, movable allocations could be disallowed from CMA through
PF_MEMALLOC_PIN. As CMA pages are funneled through the MOVABLE pcplist,
this required filtering that cornercase during allocations, such that
pinnable allocations wouldn't accidentally get a CMA page.
However, since 8e3560d963d2 ("mm: honor PF_MEMALLOC_PIN for all movable
pages"), PF_MEMALLOC_PIN automatically excludes __GFP_MOVABLE. Once
again, MOVABLE implies CMA is allowed.
Remove the stale filtering code. Also remove a stale comment that was
introduced as part of the filtering code, because the filtering let
order-0 pages fall through to the buddy allocator. See 1d91df85f399
("mm/page_alloc: handle a missing case for memalloc_nocma_{save/restore}
APIs") for context. The comment's been obsolete since the introduction of
the explicit ALLOC_HIGHATOMIC flag in eb2e2b425c69 ("mm/page_alloc:
explicitly record high-order atomic allocations in alloc_flags").
