This helps to identify where vb_lock is being used, and find missusages of the
locks.

0b29669c06 V4L/DVB (6751): V4L: Memory leak! Fix count in videobuf-vmalloc mmap
This is pretty serious bug.  map->count is never initialized after the
call to kmalloc making the count start at some random trash value.  The
end result is leaking videobufs.

Also, fix up the debug statements to print unsigned values.

Pushed to http://ifup.org/hg/v4l-dvb too

Breaks on any target that has copy_to_user() defined as a non-trivial
macro.

d4cae5a500 V4L/DVB (6292): videobuf_core init always require callback implementation
In the past, videobuf_queue_init were used to initialize PCI DMA videobuffers.
This patch renames it, to avoid confusion with the previous kernel API, doing:
	s/videobuf_queue_init/void videobuf_queue_core_init/

Also, the operations is now part of the function parameter. The function will
also add a test if this is defined, otherwise producing BUG.

87b9ad070c V4L/DVB (6254): Add videobuf-vmalloc
Adds a newer videobuf-vmalloc module. This module uses the same
videobuf controls, but implements memory allocation based on vmalloc
methods.

With this method, an USB driver can use video-buf, without needing to
request memory from the DMA-safe area.
