When the devfreq cooling device was designed, it was an oversight not to
pass a pointer to the struct devfreq as the first parameters of the
callbacks. The design patterns of the kernel suggest it for a good
reason.
By passing a pointer to struct devfreq, the driver can register one
function that works with multiple devices. With the current
implementation, a driver that can work with multiple devices has to
create multiple copies of the same function with different parameters so
that each devfreq_cooling_device can use the appropriate one. By
passing a pointer to struct devfreq, the driver can identify which
device it's referring to.

Support the "cec" optional clock. The documentation already mentions "cec"
optional clock and it is used by several boards, but currently the driver
doesn't enable it, thus preventing cec from working on those boards.
And even worse: a /dev/cecX device will appear for those boards, but it
won't be functioning without configuring this clock.
Changes:
v4:
- Change commit message to stress the importance of this patch
v3:
- Drop useless braces
v2:
- Separate ENOENT errors from others
- Propagate other errors (especially -EPROBE_DEFER)

When userspace closes a handle, we remove it from the file->object_idr
and then tell the driver to drop its references to that file/handle.
However, as the file/handle is already available again for reuse, it may
be reallocated back to userspace and active on a new object before the
driver has had a chance to drop the old file/handle references.
Whilst calling back into the driver, we have to drop the
file->table_lock spinlock and so to prevent reusing the closed handle we
mark that handle as stale in the idr, perform the callback and then
remove the handle. We set the stale handle to point to the NULL object,
then any idr_find() whilst the driver is removing the handle will return
NULL, just as if the handle is already removed from idr.
Note: This will be used to have a direct handle -> vma lookup table,
instead of first a handle -> obj lookup, and then an (obj, vm) -> vma
lookup.
v2: Use NULL rather than an ERR_PTR to avoid having to adjust callers.
idr_alloc() tracks existing handles using an internal bitmap, so we are
free to use the NULL object as our stale identifier.
v3: Needed to update the return value check after changing from using
the stale error pointer to NULL.

Rockchip requires bo-pages to be in the DMA32 zone. Explicitly request this
by setting __GFP_DMA32 as mapping-gfp-mask during shmem initialization.
This drops HIGHMEM from the gfp-mask and uses DMA32 instead. shmem-core
takes care to relocate pages during swap-in in case they have been loaded
into the wrong zone.
It is _not_ possible to pass __GFP_DMA32 to shmem_read_mapping_page_gfp()
as the page might have already been swapped-in at that time. The zone-mask
must be set during initialization and be kept constant for now.
