Because the core by default clips the src/dst properties, after
the drm_atomic_helper_check_plane_state() we manually set the

Commit 721b1d98fb ("dm snapshot: Fix excessive memory usage and
workqueue stalls") introduced a semaphore to limit the maximum number of
in-flight kcopyd (COW) jobs.
The implementation of this throttling mechanism is prone to a deadlock:
1. One or more threads write to the origin device causing COW, which is
performed by kcopyd.
2. At some point some of these threads might reach the s->cow_count
semaphore limit and block in down(&s->cow_count), holding a read lock
on _origins_lock.
3. Someone tries to acquire a write lock on _origins_lock, e.g.,
snapshot_ctr(), which blocks because the threads at step (2) already
hold a read lock on it.
4. A COW operation completes and kcopyd runs dm-snapshot's completion
callback, which ends up calling pending_complete().
pending_complete() tries to resubmit any deferred origin bios. This
requires acquiring a read lock on _origins_lock, which blocks.
This happens because the read-write semaphore implementation gives
priority to writers, meaning that as soon as a writer tries to enter
the critical section, no readers will be allowed in, until all
writers have completed their work.
So, pending_complete() waits for the writer at step (3) to acquire
and release the lock. This writer waits for the readers at step (2)
to release the read lock and those readers wait for
pending_complete() (the kcopyd thread) to signal the s->cow_count
semaphore: DEADLOCK.
The above was thoroughly analyzed and documented by Nikos Tsironis as
part of his initial proposal for fixing this deadlock, see:
https://www.redhat.com/archives/dm-devel/2019-October/msg00001.html
Fix this deadlock by reworking COW throttling so that it waits without
holding any locks. Add a variable 'in_progress' that counts how many
kcopyd jobs are running. A function wait_for_in_progress() will sleep if
'in_progress' is over the limit. It drops _origins_lock in order to
avoid the deadlock.

ACPI tables aren't available if Linux runs as guest of the hypervisor
Jailhouse. This makes the 8250 driver probe for all platform UARTs as it
assumes that all UARTs are present in case of !ACPI. Jailhouse will stop
execution of Linux guest due to port access violation.
So far, these access violations were solved by tuning the 8250.nr_uarts
cmdline parameter, but this has limitations: Only consecutive platform
UARTs can be mapped to Linux, and only in the sequence 0x3f8, 0x2f8,
0x3e8, 0x2e8.
Beginning from setup_data version 2, Jailhouse will place information of
available platform UARTs in setup_data. This allows for selective
activation of platform UARTs.
Query setup_data version and only activate available UARTS. This
patch comes with backward compatibility, and will still support older
setup_data versions. In case of older setup_data versions, Linux falls
back to the old behaviour.

Soon, setup_data will contain information on passed-through platform
UARTs. This requires some preparational work for the sanity check of the
header and the check of the version.
Use the following strategy:
1. Ensure that the header declares at least enough space for the
version and the compatible_version as it must hold that fields for
any version. The location and semantics of header+version fields
will never change.
2. Copy over data -- as much as as possible. The length is either
limited by the header length or the length of setup_data.
3. Things are now in place -- sanity check if the header length
complies the actual version.
For future versions of the setup_data, only step 3 requires alignment.
