At least since nodemgr got rid of coarse global locking, accesses to
struct csr1212_keyval's reference counter should be atomic and coupled
with proper barriers. Also, calls to csr1212_keep_keyval(kv) should
occur before kv is being used.
(We probably should convert refcnt to struct kref, but how to keep
csr1212_destroy_keyval's implementation non-recursively then?)

The biggest chunk ever allocated by CSR1212_MALLOC is 1024 Bytes +
sizeof(struct csr1212_csr_rom_cache) big. Most of the time much
smaller data structures are allocated. Therefore vmalloc is a waste.
The one exception is csr1212_append_new_cache() which is called to
append a chunk of CSR1212_EXTENDED_ROM_SIZE + sizeof(struct
csr1212_csr_rom_cache) if the currently allocated ROM cache is too
small. CSR1212_EXTENDED_ROM_SIZE is generously defined as 256 kBytes.
In SVN commit 1220, Steve Kinneberg lowered this to 2 kBytes in the
config_rom_2.4 branch. This same commit also switched CSR1212_MALLOC
from kmalloc to vmalloc in the SVN trunk branch:

I am now setting CSR1212_EXTENDED_ROM_SIZE to 2 kB minus the overhead of
struct csr1212_csr_rom_cache. Note, this code path is not used by the
in-kernel drivers though. raw1394 could trigger it, but the respective
libraw1394 functions don't exist yet.
Furthermore, userspace programs can replace the entire local ROM via
raw1394. If kmalloc does not fulfill their needs --- well, tough luck.
I decree that nobody needs such huge extended ROMs. (Extended ROMs are
defined by IEEE 1212 clause 7.7.18. The spec does not impose
practically relevant restrictions on the size of extended ROM chunks.)
Another potentially demanding use of CSR1212_MALLOC is if external
FireWire devices come with Extended ROM entries. If they are too big
for kmalloc (or have been too big for vmalloc) we just fail to read
their ROM. This is quite unlikely though, to my knowledge.

csr1212 was written to be compiled either as part of the ieee1394 kernel
driver or of an anticipated IEEE 1212 userspace library. We now drop
support for the latter. The costs in terms of code footprint and depth
of abstraction are not countered by any actual benefit.
Also remove some obsolete #includes.

The whole ROM area which is covered by the crc_length field of the ROM
header was fetched before the info_length field was checked for correct
general ROM format. This might be wasteful or even dangerous with nodes
with minimal ROM, nonstandard ROM, or corrupt ROM.
Perform this check at the earliest opportunity.

This patch applies a little change in csr1212.c to fix iSight (firewire
digital camera) related issues (but maybe other firewire devices could
also need such modification)
The actual implementation of the "csr1212_key_id_type_map" table doesn't
support some node types used by the iSight for the audio unit. This
limit makes the csr scanning routine to never see the audio unit node ,
and consequently the iSight driver probe() routine to be never called
and there is no way to hook an isight device when it is inserted.

csr1212_parse_csr() did not properly check return values when reading
keyvals. Fix this by using _csr1212_read_keyval() instead of
csr1212_get_keyval() and checking the return code.

Lots of this patch is trivial code cleanups (static vars were being
intialized to 0, etc).
There's also some fixes for ISO transmits (max buffer handling).
Aswell, we have a few fixes to disable IRM capabilites correctly. We've
also disabled, by default some generally unused EXPORT symbols for the
sake of cleanliness in the kernel. However, instead of removing them
completely, we felt it necessary to have a config option that allowed
them to be enabled for the many projects outside of the main kernel tree
that use our API for driver development.
The primary reason for this patch is to revert a MODE6->MODE10 RBC
conversion patch from the SCSI maintainers. The new conversions handled
directly in the scsi layer do not seem to work for SBP2. This patch
reverts to our old working code so that users can enjoy using Firewire
disks and dvd drives again.
We are working with the SCSI maintainers to resolve this issue outside
of the main kernel tree. We'll merge the patch once the SCSI layer's
handling of the MODE10 conversion is working for us.

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!
