Until we support p2p dma or as a complement to that, migrate data

If our exported dma-bufs are imported by another instance of our driver,
that instance will typically have the imported dma-bufs locked during
map_attachment(). But the exporter also locks the same reservation
object in the map_dma_buf() callback, which leads to recursive locking.

While checking the master status of the DRM file in
drm_is_current_master(), the device's master mutex should be
held. Without the mutex, the pointer fpriv->master may be freed
concurrently by another process calling drm_setmaster_ioctl(). This
could lead to use-after-free errors when the pointer
Currently, direct copies of drm_file->master pointers should be
protected by drm_device.master_mutex when being dereferenced. This is
because drm_file->master is not invariant for the lifetime of
drm_file. If drm_file is not the creator of master, then
drm_file->is_master is false, and a call to

As per commit 22be87401289 ("drm: TODO: Add DRM_MODESET_LOCK_ALL*
conversion to todo.rst"),
drm_modeset_lock_all()/drm_modeset_unlock_all() and boilerplate code
surrounding instances of drm_modeset_lock_all_ctx() with a local acquire
context should be replaced with the relevant helper macros.

Reinstate the mmap ioctl for all current integrated platforms.
The intention was really to have it disabled for discrete graphics
where we enforce a single mmap mode.
This fixes media on rkl/adl.

- Added a R-B.
- Fixed up the code comment a bit.
v3:

If our exported dma-bufs are imported by another instance of our driver,
that instance will typically have the imported dma-bufs locked during
map_attachment(). But the exporter also locks the same reservation
object in the map_dma_buf() callback, which leads to recursive locking.
Add a live
Until we support p2p dma or as a complement to that, migrate data
to system memory at dma-buf map time if possible.

- Rebase on dynamic exporter. Update the igt_dmabuf_import_same_driver

Introduce an interface to migrate objects between regions.
This is primarily intended to migrate objects to LMEM for display and
to SYSTEM for dma-buf, but might be reused in one form or another for
performande-based migration.
v2:
- Verify that the memory region given as an id really exists.
We want to be able to explicitly migrate objects between gem memory
regions, initially for display and dma-buf, but there might be more
use-cases coming up.
Introduce a gem migrate interface, add a selftest and use it for
display fb pinning and dma-buf mapping.
