V4L/DVB (12326): zr364xx: error message when buffer is too small and code cleanup

. added code to print an error message when buffer is too small to hold frame
data, that is better than just a hard crash. Tested using MAX_FRAME_SIZE =
50000, lots of error messages appeared in /var/log/messages but no crash.

. removed line "f->type = V4L2_BUF_TYPE_VIDEO_CAPTURE;" in
zr364xx_vidioc_try_fmt_vid_cap, it should not be there.

. changes to improve performance (or at least not hurt it): removed some
unneeded debug messages; added macro FULL_DEBUG to enable debug messages in
performance critical places, this macro is disabled by default; removed "if
(frm->lpvbits == NULL)..." in zr364xx_read_video_callback because after
analisying the source code I concluded it will always results to false, so it
is not needed.

However our save stack backtrace code relies on it. If the pointer

lockdep however relies (correctly) on the fact that that cannot

[S390] fix recursive locking on page_table_lock

Suzuki Poulose reported the following recursive locking bug on s390:

Here is the stack trace : (see Appendix I for more info)

  [<0000000000406ed6>] _spin_lock+0x52/0x94
  [<0000000000103bde>] crst_table_free+0x14e/0x1a4

  [<00000200001642b2>] 0x200001642b2

The page_table_lock is already acquired in __pmd_alloc (mm/memory.c) and
it tries to populate the pud/pgd with a new pmd allocated. If another
thread populates it before we get a chance, we free the pmd using
pmd_free().

On s390x, pmd_free(even pud_free ) is #defined to crst_table_free(),
which acquires the page_table_lock to protect the crst_table index updates.

Hence this ends up in a recursive locking of the page_table_lock.

The solution suggested by Dave Hansen is to use a new spin lock in the mmu
context to protect the access to the crst_list and the pgtable_list.
