accel/habanalabs: fix bug in timestamp interrupt handling
[ Upstream commit 0165994c215f321e2d055368f89b424756e340eb ]
There is a potential race between user thread seeking to re-use
a timestamp record with new interrupt id, while this record is still
in the middle of interrupt handling and it is about to be freed.
Imagine the driver set the record in_use to 0 and only then fill the
free_node information. This might lead to unpleasant scenario where
the new registration thread detects the record as free to use, and
change the cq buff address. That will cause the free_node to get
the wrong buffer address to put refcount to.

accel/habanalabs: export dma-buf only if size/offset multiples of PAGE_SIZE
[ Upstream commit 0b75cb5b240fddf181c284d415ee77ef61b418d6 ]
It is currently allowed for a user to export dma-buf with size and
offset that are not multiples of PAGE_SIZE.
The exported memory is mapped for the importer device, and there it will
be rounded to PAGE_SIZE, leading to actually exporting more than the
user intended to.
To make the user be aware of it, accept only size and offset which are
multiple of PAGE_SIZE.
