Nuvia has been acquired by Qualcomm and the vendor name 'nuvia' will
not be used anymore so rename aspeed-bmc-nuvia-dc-scm.dts to
aspeed-bmc-qcom-dc-scm-v1.dts and change 'nuvia' to 'qcom' as its vendor
name in the file.

Memory controller drivers - fixes for v5.19
Broken in current cycle:
1. OMAP GPMC: fix Kconfig dependency for OMAP_GPMC, so it will not be visible
for everyone (driver is specific to OMAP).
Broken before:
1. Mediatek SMI: fix missing put_device() in error paths.
2. Exynos DMC: fix OF node leaks in error paths.

Samsung fixes for v5.19
Both fixes are for issues present before v5.19 merge window:
1. Correct UART clocks on Exynos7885. Although the initial, fixed
DTS commit is from v5.18, the issue will be exposed with a upcoming fix
to Exynos7885 clock driver, so we need to correct the DTS earlier.
2. Fix theoretical OF node leak in Exynos machine code.

We use cifs_tcp_ses_lock to protect a lot of things.
Not only does it protect the lists of connections, sessions,
tree connects, open file lists, etc., we also use it to
protect some fields in each of it's entries.
In this case, cifs_mark_ses_for_reconnect takes the
cifs_tcp_ses_lock to traverse the lists, and then calls
cifs_update_iface. However, that can end up calling
cifs_put_tcp_session, which picks up the same lock again.
Avoid this by taking a ref for the session, drop the lock,
and then call update iface.
Also, in cifs_update_iface, avoid nested locking of iface_lock
and chan_lock, as much as possible. When unavoidable, we need
to pick iface_lock first.

Re-reading a recently merged fix to the raw_gadget driver showed that
it inadvertently introduced a double-free bug in a failure pathway.
If raw_ioctl_init() encounters an error after the driver ID number has
been allocated, it deallocates the ID number before returning. But
when dev_free() runs later on, it will then try to deallocate the ID
number a second time.
Closely related to this issue is another error in the recent fix: The
ID number is stored in the raw_dev structure before the code checks to
see whether the structure has already been initialized, in which case
the new ID number would overwrite the earlier value.
The solution to both bugs is to keep the new ID number in a local
variable, and store it in the raw_dev structure only after the check
for prior initialization. No errors can occur after that point, so
the double-free will never happen.

The ccp driver loops through the platform device resources array to get
the IRQ count for the device. With commit a1a2b7125e10 ("of/platform: Drop
static setup of IRQ resource from DT core"), the IRQ resources are no
longer stored in the platform device resource array. As a result, the IRQ
count is now always zero. This causes the driver to issue a second call to
platform_get_irq(), which fails if the IRQ count is really 1, causing the
loading of the driver to fail.
Replace looping through the resources array to count the number of IRQs
with a call to platform_irq_count().

We try to harden virtio device notifications in 8b4ec69d7e09 ("virtio:
harden vring IRQ"). It works with the assumption that the driver or
core can properly call virtio_device_ready() at the right
place. Unfortunately, this seems to be not true and uncover various
bugs of the existing drivers, mainly the issue of using
virtio_device_ready() incorrectly.
So let's add a Kconfig option and disable it by default. It gives
us time to fix the drivers and then we can consider re-enabling it.

the used_wrap_counter and the vq->last_used_idx may get
out of sync if they are separate assignment，and interrupt
might use an incorrect value to check for the used index.
for example:OOB access
ksoftirqd may consume the packet and it will call:
virtnet_poll
-->virtnet_receive
-->virtqueue_get_buf_ctx
-->virtqueue_get_buf_ctx_packed
and in virtqueue_get_buf_ctx_packed:
vq->last_used_idx += vq->packed.desc_state[id].num;
if (unlikely(vq->last_used_idx >= vq->packed.vring.num)) {
vq->last_used_idx -= vq->packed.vring.num;
vq->packed.used_wrap_counter ^= 1;
}
if at the same time, there comes a vring interrupt，in vring_interrupt:
we will call:
vring_interrupt
-->more_used
-->more_used_packed
-->is_used_desc_packed
in is_used_desc_packed, the last_used_idx maybe >= vq->packed.vring.num.
so this could case a memory out of bounds bug.
this patch is to keep the used_wrap_counter in vq->last_used_idx
so we can get the correct value to check for used index in interrupt.
v3->v4:
- use READ_ONCE/WRITE_ONCE to get/set vq->last_used_idx
v2->v3:
- add inline function to get used_wrap_counter and last_used
- when use vq->last_used_idx, only read once
if vq->last_used_idx is read twice, the values can be inconsistent.
- use last_used_idx & ~(-(1 << VRING_PACKED_EVENT_F_WRAP_CTR))
to get the all bits below VRING_PACKED_EVENT_F_WRAP_CTR
v1->v2:
- reuse the VRING_PACKED_EVENT_F_WRAP_CTR
- Remove parameter judgment in is_used_desc_packed,
because it can't be illegal

vduse devices are not backed by any real devices such as PCI. Hence it
doesn't have any parent device linked to it.
Kernel driver model in [1] suggests to avoid an empty device
release callback.
Hence tie the mgmtdevice object's life cycle to an allocate dummy struct
device instead of static one.

syzbot reported uninit-value in tcp_recvmsg() [1]
Issue here is that msg->msg_get_inq should have been cleared,
otherwise tcp_recvmsg() might read garbage and perform
more work than needed, or have undefined behavior.
Given CONFIG_INIT_STACK_ALL_ZERO=y is probably going to be
the default soon, I chose to change __sys_recvfrom() to clear
all fields but msghdr.addr which might be not NULL.
For __copy_msghdr_from_user(), I added an explicit clear
of kmsg->msg_get_inq.

The current blocking mechanism for pushing the inodegc queue out to
disk can result in systems becoming unusable when there is a long
running inodegc operation. This is because the statfs()
implementation currently issues a blocking flush of the inodegc
queue and a significant number of common system utilities will call
statfs() to discover something about the underlying filesystem.
This can result in userspace operations getting stuck on inodegc
progress, and when trying to remove a heavily reflinked file on slow
storage with a full journal, this can result in delays measuring in
hours.
Avoid this problem by adding "push" function that expedites the
flushing of the inodegc queue, but doesn't wait for it to complete.
Convert xfs_fs_statfs() and xfs_qm_scall_getquota() to use this
mechanism so they don't block but still ensure that queued
operations are expedited.

Currently inodegc work can sit queued on the per-cpu queue until
the workqueue is either flushed of the queue reaches a depth that
triggers work queuing (and later throttling). This means that we
could queue work that waits for a long time for some other event to
trigger flushing.
Hence instead of just queueing work at a specific depth, use a
delayed work that queues the work at a bound time. We can still
schedule the work immediately at a given depth, but we no long need
to worry about leaving a number of items on the list that won't get
processed until external events prevail.

Commit 85e123c27d5c ("dm mirror log: round up region bitmap size to
BITS_PER_LONG") introduced a regression on 64-bit architectures in the
lvm testsuite tests: lvcreate-mirror, mirror-names and vgsplit-operation.
If the device is shrunk, we need to clear log bits beyond the end of the
device. The code clears bits up to a 32-bit boundary and then calculates
lc->sync_count by summing set bits up to a 64-bit boundary (the commit
changed that; previously, this boundary was 32-bit too). So, it was using
some non-zeroed bits in the calculation and this caused misbehavior.
Fix this regression by clearing bits up to BITS_PER_LONG boundary.

Commit 7dd76d1feec7 ("dm: improve bio splitting and associated IO
accounting") removed using cloned bio when dm io splitting is needed.
Using bio_trim()+bio_inc_remaining() rather than bio_split()+bio_chain()
causes multiple dm_io instances to share the same original bio, and it
works fine if IOs are completed successfully.
But a regression was caused for the case when BLK_STS_DM_REQUEUE is
returned from any one of DM's cloned bios (whose dm_io share the same
orig_bio). In this BLK_STS_DM_REQUEUE case only the mapped subset of
the original bio for the current exact dm_io needs to be re-submitted.
However, since the original bio is shared among all dm_io instances,
the ->orig_bio actually only represents the last dm_io instance, so
requeue can't work as expected. Also when more than one dm_io is
requeued, the same original bio is requeued from all dm_io's
completion handler, then race is caused.
Fix this issue by still allocating one clone bio for completing io
only, then io accounting can rely on ->orig_bio being unmodified. This
is needed because the dm_io's sector_offset and sectors members are
recorded relative to an unmodified ->orig_bio.
In the future, we can go back to using bio_trim()+bio_inc_remaining()
for dm's io splitting but then delay needing a bio clone only when
handling BLK_STS_DM_REQUEUE, but that approach is a bit complicated
(so it needs a development cycle):
1) bio clone needs to be done in task context
2) a block interface for unwinding bio is required

During msm initialize phase, dp_display_unbind() will be called to undo
initializations had been done by dp_display_bind() previously if there is
error happen at msm_drm_bind. Under this kind of circumstance, drm_device
may not be populated completed which causes system crash at drm_dev_dbg().
This patch reset drm_dev to NULL so that following drm_dev_dbg() will not
refer to any internal fields of drm_device to prevent system from crashing.

The 'vsync_cnt' is used to count the number of frames for a crtc.
Unfortunately, we increment the count after waking up userspace via
dpu_crtc_vblank_callback() calling drm_crtc_handle_vblank().
drm_crtc_handle_vblank() wakes up userspace processes that have called
drm_wait_vblank_ioctl(), and if that ioctl is expecting the count to
increase it won't.
Increment the count before calling into the drm APIs so that we don't
have to worry about ordering the increment with anything else in drm.
This fixes a software video decode test that fails to see frame counts
increase on Trogdor boards.
