This patch changes function gfs2_adjust_quota so that it properly
returns a good (zero) return code on the normal path through the code.
Without this, mounting GFS2 with -o quota=account periodically gave
this error message: GFS2: fsid=cluster:fs: gfs2_quotad: sync error -5

This is a second attempt at a patch that adds rgrp information to the
block allocation trace point for GFS2. As suggested, the patch was
modified to list the rgrp information _after_ the fields that exist today.
Again, the reason for this patch is to allow us to trace and debug
problems with the block reservations patch, which is still in the works.
We can debug problems with reservations if we can see what block allocations
result from the block reservations. It may also be handy in figuring out
if there are problems in rgrp free space accounting. In other words,
we can use it to track the rgrp and its free space along side the allocations
that are taking place.

It turns out that the "new" parameter to function gfs2_meta_indirect_buffer
was always being passed in as zero. Therefore, this patch eliminates it
and simplifies the function.

This cleans up the mode setting code when creating inodes. The
SGID bit was being reset by setattr_copy() when the user creating a
subdirectory was not in the owning group. When ACLs are in use this
SGID bit should have been propagated if the ACL allows creation of
a subdirectory. GFS2's behaviour now matches that of the other ACL
supporting filesystems in this regard.

gfs2_internal_read accepts an unused ra_state argument, left over from
when we did readahead on the rindex. Since there are currently no plans
to add back this readahead, this patch removes the ra_state parameter
and updates the functions which call gfs2_internal_read accordingly.

This is another clean up in the logging code. This per-transaction
list was largely unused. Its main function was to ensure that the
number of buffers in a transaction was correct, however that counter
was only used to check the number of buffers in the bd_list_tr, plus
an assert at the end of each transaction. With the assert now changed
to use the calculated buffer counts, we can remove both bd_list_tr and
its associated counter.
This should make the code easier to understand as well as shrinking
a couple of structures.

The main part of this patch merges the two functions used to
write metadata and data buffers to the log. Most of the code
is common between the two functions, so this provides a nice
clean up, and makes the code more readable.
The gfs2_get_log_desc() function is also extended to take two more
arguments, and thus avoid having to set the length and data1
fields of this strucuture as a separate operation.

Prior to this patch, we have two ways of sending i/o to the log.
One of those is used when we need to allocate both the data
to be written itself and also a buffer head to submit it. This
is done via sb_getblk and friends. This is used mostly for writing
log headers.
The other method is used when writing blocks which have some
in-place counterpart. This is the case for all the metadata
blocks which are journalled, and when journaled data is in use,
for unescaped journalled data blocks.
This patch replaces both of those two methods, and about half
a dozen separate i/o submission points with a single i/o
submission function. We also go direct to bio rather than
using buffer heads, since this allows us to build i/o
requests of the maximum size for the block device in
question. It also reduces the memory required for flushing
the log, which can be very useful in low memory situations.

In the future, the qadata structure will be eliminated and merged
back in with the block reservation structure, after we extend the
lifespan of that. This patch is a step forward in eliminating the
qadata structure. It adds a variable to the do_grow function to
determine when unstuffing is necessary, and has been done.

In the resource group code, we have no less than three different
kinds of block references: block relative to the file system (u64),
block relative to the rgrp (u32), and block relative to the bitmap.
This is a small step to making the code more readable; it renames
variable blk to biblk to solidify in my mind that it's relative to
the bitmap and nothing else.

The "pull" argument to log_write_header() is only used
for debug purposes and it is not really needed any more. There
are other tests for this particular problem, so I think we can
dispose of it in order to simplify the code.

Pull m68knommu tree from Greg Ungerer:
"More merge and clean up of MMU and non-MMU common files, namely
signal.c and dma.c. There is also a simplification of the ColdFire
GPIO setup tables. Using a couple of simple macros we make the init
tables really small and easy to read, and save a couple of thousand
lines of code. Also a move of all the ColdFire subarch support files
into the existing coldfire directory. The sub-directories just ended
up duplicating Makefiles and now only contain really simple pieces of
code. This saves quite a few lines of code too.
As always a couple of bugs fixes thrown in too. Oh and a new
defconfig for the ColdFire platforms that support having the MMU
enabled."

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
The main alloc and free routines are a little different, so we keep a
single #ifdef based on CONFIG_MMU for them. All the other support functions
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.
