1c4fb577aa ieee1394: Storage class should be before const qualifier
The C99 specification states in section 6.11.5:

The placement of a storage-class specifier other than at the beginning
of the declaration specifiers in a declaration is an obsolescent
feature.

e47c1feb17 ieee1394: fix list corruption (reported at module removal)
If there is more than one FireWire controller present, dummy_zero_addr
and dummy_max_addr were added multiple times to different lists, thus
corrupting the lists.  Fix this by allocating them dynamically per host
instead of just once globally.

(Perhaps a better address space allocation algorithm could rid us of the
two dummy address spaces.)

Fixes http://bugzilla.kernel.org/show_bug.cgi?id=10129 .

055a7da0bb ieee1394: video1394: reorder module init, prepare BKL removal
This prepares video1394 for removal of the BKL (big kernel lock):
It allows video1394_open() to be called while video1394_init_module()
is still in progress.

53c96b4174 ieee1394: remove old isochronous ABI
Based on patch "the scheduled removal of RAW1394_REQ_ISO_{SEND,LISTEN}"
from Adrian Bunk, November 20 2006.

This patch also removes the underlying facilities in ohci1394 and
disables them in pcilynx.  That is, hpsb_host_driver.devctl() and
hpsb_host_driver.transmit_packet() are no longer used for iso reception
and transmission.

Since video1394 and dv1394 only work with ohci1394 and raw1394's rawiso
interface has never been implemented in pcilynx, pcilynx is now no
longer useful for isochronous applications.

raw1394 will still handle the request types but will complete the
requests with errors that indicate API version conflicts.

445151932e ieee1394: hl_irqs_lock is taken in hardware interrupt context
ohci1394 and pcilynx call highlevel_host_reset from their hardware
interrupt handler (via hpsb_selfid_complete).  Therefore all readers and
writers of hl_irqs_lock have to disable interrupts.  Reported by Jiri
Slaby and J. A. Magallon.

8aef63ff03 ieee1394: extend lowlevel API for address range properties
Host adapter hardware imposes certain restrictions and features on
address ranges.  Instead of hard-wire such ranges into the ieee1394
core or even into protocol drivers, let lowlevel drivers specify
these ranges via struct hpsb_host.

Patch "ohci1394: set address range properties" must be applied too,
else hpsb_allocate_and_register_addrspace() won't work properly.

37d54111c1 [PATCH] bitops: hweight() related cleanup
By defining generic hweight*() routines

- hweight64() will be defined on all architectures
- hweight_long() will use architecture optimized hweight32() or hweight64()

I found two possible cleanups by these reasons.

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!
