Configure the inactivity timeout passed in start_ap() to
firmware. This capability is advertised only when fw supports
it, there is a new bit (ATH6KL_FW_CAPABILITY_INACTIVITY_TIMEOUT)
in firmware capability ie for driver to learn fw's capability.
After the fw finds out the station is inactive, it will probe
the station with null func frames. By default, the timeout is
10 secs.

to configure the host sleep mode is needed in deep sleep
case also.
Moving that portion to a separate function called
ath6kl_update_host_mode() would be helpful to avoid
the duplication of the same code in deep sleep path.
There is no functional change.

Originally the code tried to allocate a large enough array to perform
the copy using vmalloc, performance wasn't great and throughput was
improved by processing each individual relocation entry separately.
This too is not as efficient as one would desire. A compromise would be
to allocate a single page, or to allocate a few entries on the stack,
and process the copy in batches. The latter gives simpler code and more
consistent performance due to a lack of heuristic.

When a tablet connect or disconnect is detected, schedule
work queue to register or unregister related input devices.
When a wireless tablet connects, it reports same USB PID
used if tablet is connected with USB cable. Use this to
update features values, set input capabilities, and then
register device. From there, the Pen and Touch interfaces
will reuse the existing tablet's IRQ routines.
Its possible that 1 receiver is shared with 2 tablets with
different PID (small and medium Bamboo for example) so the
input is unregister at disconnect to better support this case.

The 3rd gen Bamboo Pen & Touch and Intuos5 tablets support an
optional wireless module. When its receiver is plugged into USB,
it presents 3 interfaces: 0) Monitor 1) Pen and 2) Touch.
The exact capabilities of the Pen and Touch interfaces can
not be determined until a tablet connection is established
and reported over the Monitor interface.
This patch detects this wireless receiver and enables interrupt
packets to be processed for the Monitor interface. Processing
the data in packets will be left to another patch.
Since it doesn't make sense to create an input device for the
Monitor interface, it is not created. Creation of Pen and Touch
input device is also delayed until monitor packets can be processed.

Big differences to other contenders in the field (like ion) is
that this also supports highmem, so we have to split up the cpu
access from the kernel side into a prepare and a kmap step.
Prepare is allowed to fail and should do everything required so that
the kmap calls can succeed (like swapin/backing storage allocation,
flushing, ...).
More in-depth explanations will follow in the follow-up documentation
patch.
Changes in v2:
- Clear up begin_cpu_access confusion noticed by Sumit Semwal.
- Don't automatically fallback from the _atomic variants to the
non-atomic variants. The _atomic callbacks are not allowed to
sleep, so we want exporters to make this decision explicit. The
function signatures are explicit, so simpler exporters can still
use the same function for both.
- Make the unmap functions optional. Simpler exporters with permanent
mappings don't need to do anything at unmap time.
Changes in v3:
- Adjust the WARN_ON checks for the new ->ops functions as suggested
by Rob Clark and Sumit Semwal.
- Rebased on top of latest dma-buf-next git.
Changes in v4:
- Fixup a missing - in a return -EINVAL; statement.

The mutex protects the attachment list and hence needs to be held
around the callbakc to the exporters (optional) attach/detach
functions.
Holding the mutex around the map/unmap calls doesn't protect any
dma_buf state. Exporters need to properly protect any of their own
state anyway (to protect against calls from their own interfaces).
So this only makes the locking messier (and lockdep easier to anger).
Therefore let's just drop this.

Some exporters may use DMA map/unmap APIs in dma-buf ops, which require
