Finally there, just needs a lot of fixes!
A lot of places were calling certain calls without any object lock held,
with the removal of mm.lock we can no longer do this, and have to fix it.
Phys page handling has to be redone, as nothing protects obj->ops structure,
we have to remove swapping it, and move HAS_STRUCT_PAGE to obj->flags instead.
Userpointer locking is inverted, which we tried to get around with a workqueue.
We correct the lock ordering and try to acquire userptr pages first before taking
any ww locks. This is more compatible with the locking hierarchy, as we may need
to acquire mmap_sem.
The previous versione broke gem_exec_schedule@pi-shared/distinct-iova, but
now that we only unbind when required, this is now fixed.
We also have to fix some dma-work, the command parser and clflush are slightly
reworked to put all memory allocations and pinning in the preparation,
so the work could pass fence annotations.
In a few places like igt_spinner and execlists, we move some part of init to the
first pin, because we need to have the ww lock held and it makes it easier that way.
Finally we convert all selftests, and then remove obj->mm.lock!
Previous version had some issues with hwsp, those are now fixed. A memset was
missing, and has been re-added.
Some issues with userptr double lock popped up. Userptr notifier_lock
is now a spinlock as it should only be held for very short amounts of time
and sleeping is not allowed, and now correctly unlocked when invalidating.
This should fix the remaining test issues.
