We use a variety of different names for the indirect disc address of
the current object, use a variety of different types, and print it in
a variety of different ways. Bring some consistency to this by naming
it "indaddr", use u32 or __u32 as the type since it fits in 32-bits,
and always print it with %06x (with no leading hex prefix.)
When printing it was a directory identifer, use "dir %06x" otherwise
use "object %06x".
Do the same for fragment IDs and the parent indirect disc addresses.

Add a helper to get the disc record from the map, rather than open
coding this in adfs_fill_super().

Pull ADFS cleanups/fixes from Russell King:
"As a result of some of Al Viro's great work, here are a few cleanups
with fixes for adfs:
- factor out filename comparison, so we can be sure that
adfs_compare() (used for namei compare) and adfs_match() (used for
lookup) have the same behaviour.
- factor out filename lowering (which is not the same as tolower()
which will lower top-bit-set characters) to ensure that we have the
same behaviour when comparing filenames as when we hash them.
- factor out the object fixups, so we are applying all fixups to
directory objects in the same way, independent of the disk format.
- factor out the object name fixup (into the previously factored out
function) to ensure that filenames are appropriately translated -
for example, adfs allows '/' in filenames, which being the Unix
path separator, need to be translated to a different character,
which is normally '.' (DOS 8.3 filenames represent the . as a / on
adfs, so this is the expected reverse translation.)
- remove filename truncation; Al asked about this and apparently the
decision is to remove it. In any case, adfs's truncation was buggy,
so this rids us of that bug by removing the truncation feature.
- we now have only one location which adds the "filetype" suffix to
the filename, so there's no point that code being out of line.
- since we translate '/' into '.', an adfs filename of "/" or "//"
would end up being translated to "." and ".." which have special
meanings. In this case, change the first character to "^" to avoid
these special directory names being abused"
* tag 'for-rc-adfs' of git://git.armlinux.org.uk/~rmk/linux-arm:
fs/adfs: fix filename fixup handling for "/" and "//" names
fs/adfs: move append_filetype_suffix() into adfs_object_fixup()
fs/adfs: remove truncated filename hashing
fs/adfs: factor out filename fixup
fs/adfs: factor out object fixups
fs/adfs: factor out filename case lowering
fs/adfs: factor out filename comparison

Move the filename fixup to adfs_object_fixup() so we only have one
implementation of this.

ADFS (FileCore) storage complies with the RISC OS filetype specification
(12 bits of file type information is stored in the file load address,
rather than using a file extension). The existing driver largely ignores
this information and does not present it to the end user.
It is desirable that stored filetypes be made visible to the end user to
facilitate a precise copy of data and metadata from a hard disc (or image
thereof) into a RISC OS emulator (such as RPCEmu) or to a network share
which can be accessed by real Acorn systems.
This patch implements a per-mount filetype suffix option (use -o
ftsuffix=1) to present any filetype as a ,xyz hexadecimal suffix on each
file. This type suffix is compatible with that used by RISC OS systems
that access network servers using NFS client software and by RPCemu's host
filing system.

Fix filenames on adfs discs being terminated at the first character greater
than 128 (adfs filenames are Latin 1). I saw this problem when using a
loopback adfs image on a 2.6.17-rc5 x86_64 machine, and the patch fixed it
there.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
