The list_for_each_entry() iterator, "connector" in this code, can never be

"connector" points invalid memory that is an offset from the list head.
This will eventually lead to memory corruption and presumably a kernel

Commit 375cca1cfeb5 ("drm/vgem: Implement mmap as GEM object function")
accidentally removed the actual mmap functionality from vgem. Restore
the original implementation and VMA flags.
Fixes access to unmapped memory:
[ 106.591744] BUG: KASAN: vmalloc-out-of-bounds in do_fault+0x38/0x480
[ 106.
This is only used for ttm, and tells userspace that the mapping type is
ignored. This disables the other type of mmap offsets when discrete
memory is used, so fix the selftests as well.
Document the struct as well, so it shows up in docbook correctly.
Changes since v1:

Hi all,
Mikko has been away for a few weeks, so I've been testing and revising
the new UABI patches in the meantime. There are very minor changes to
the naming of some of the UABI fields, but other than that it's mostly
unchanged from v7.
One notable change is that mappings
From: Mikko Perttunen
Add an implementation of dma_fences based on syncpoints. Syncpoint
interrupts are used to signal fences. Additionally, after
software signaling has been enabled, a 30 second timeout is started.
If the syncpoint threshold is not reached within this period,
the fence is signal
From: Mikko Perttunen
Add a new property for jobs to enable or disable recovery i.e.
CPU increments of syncpoints to max value on job timeout. This
allows for a more solid model for hanged jobs, where userspace
doesn't need to guess if a syncpoint increment happened because
the job completed, or
From: Mikko Perttunen
Add a callback field to the job structure, to be called just before
the job is to be freed. This allows the job's submitter to clean
up any of its own state, like decrement runtime PM refcounts.

These waits need to be done in HOST1X class, while gather submitted

Changes in v8:

From: Mikko Perttunen
With the new UAPI implementation, engines are powered on and off
when there are active jobs, and the core code handles channel
allocation. To accommodate that, boot the engine as part of
runtime PM instead of using the open_channel callback, which is
not used by the new subm
From: Mikko Perttunen
To avoid code duplication, allocate the per-engine shared channel in
the core code instead. This is the usual channel that all jobs are
submitted to when MLOCKing is not in use. Once MLOCKs are implemented
on Host1x side, we can also update this to avoid allocating a shared

There is no need to free a NULL value. Instead, free the object
that is leaking due to the iterator.
