The 'ubi_scan_erase_peb()' is used only in scan.c so can be static. Also
re-name it to 'early_erase_peb()' because we tend to use "ubi_" prefix only for
non-static fuction and also because the new name is better.

After re-naming the 'struct ubi_scan_volume' we should adjust all variables
named 'sv' to something else, because 'sv' stands for "scanning volume".
Let's rename it to 'av' which stands for "attaching volume" which is
a bit more consistent and has the same length, which makes re-naming easy.

Rename 'struct ubi_scan_info' to 'struct ubi_attach_info'. This is part
of the code re-structuring I am trying to do in order to add fastmap
in a more logical way. Fastmap can share a lot with scanning, including
the attach-time data structures, which all now have "scan" word in the
name. Let's get rid of this word.

This patch removes the 'dbg_err()' macro and we now use 'ubi_err' instead.
The idea of 'dbg_err()' was to compile out some error message to make the
binary a bit smaller - but I think it was a bad idea.

We have the "sefl-check" feature in UBI, but for historical reasons many
corresponding functions and commentaries in the code use term "paranoid check"
instead. Let's clean this up and use "self-check" everywhere.
This patch renames functions, amends messages and kills several redundant
debugging messages.

Richard removed the "dtype" hint, but few commentaries were left and this patch
removes them. I've also added a better description about the "dtype" field in
the ubi-user.h for people who may ever wonder what was that dtype thing about.
This patch also adds an important note that it is better to use value "3" for
the "dtype" field.

UBI (and UBIFS) are a bit over-engineered WRT debugging. The idea was to
link as few as possible when debugging is disabled, but the downside is
that most people produce bug reports which are difficult to understand.
Always dump the VID and EC headers' contents in case of errors when it
is helpful.

This patch weeds out the 'ubi_dbg_dump_stack()' function and turns it
into 'dump_stack()' - it is always useful to have stack dump in case of

UBIFS leaks memory on error path in 'mount_ubifs()'. In case of failure in
'ubifs_fixup_free_space()', it does not call 'ubifs_lpt_free()' whereas LPT
data structures can potentially be allocated. The amount of memory leaked can
be quite high -- see 'ubifs_lpt_init()'.
The bug was introduced when moving the LPT initialisation earlier in the
mount process (commit '781c5717a95a74b294beb38b8276943b0f8b5bb4').

Most functions in UBIFS follow the following designn pattern: if the function
allocates multiple resources, and failss at some point, it frees what it has
allocated and returns an error. So the caller can rely on the fact that the
callee has cleaned up everything after own failure.

This patch fixes unaligned memory access for the 68000 core based cpu's.
Some time ago, my cpu (68000) was raising address/bus error's when mounting
cifs shares (didn't bother to debug it at the time). After developing the
MMC/SD card driver I was having the same issue when mounting the vfat fs.
I've traced the issue down to the 'unaligned.h' file. (I guess nobody has
ever used unaligned.h back in the 68328 'era'.

The majority of the m68k architecture dma code is the same, so merge the
current separated files dma_no.c and dma_mm.c back into a single dma.c

are now identical.

Introduce cache_push() and cache_clear() functions for the non-MMU m68k
devices. With these in place we can more easily merge some of the common
m68k arch code.
In particular by reorganizing the __flush_cache_all() code and separating
the cache push and clear functions it becomes trivial to implement the
new cache_push() and cache_clear() functions.
