I noticed that many source files include <linux/pci.h> while they do
not appear to need it. Here is an attempt to clean it all up.
In order to find all possibly affected files, I searched for all
files including <linux/pci.h> but without any other occurence of "pci"
or "PCI". I removed the include statement from all of these, then I
compiled an allmodconfig kernel on both i386 and x86_64 and fixed the
false positives manually.
My tests covered 66% of the affected files, so there could be false
positives remaining. Untested files are:

I would welcome test reports for these files. I am fine with removing
the untested files from the patch if the general opinion is that these
changes aren't safe. The tested part would still be nice to have.

Until now, ieee1394 put an IP-over-1394 capability entry into each new
host's config ROM. As soon as the controller was initialized --- i.e.
right after modprobe ohci1394 --- this entry triggered a hotplug event
which typically caused auto-loading of eth1394.
This irritated or annoyed many users and distributors. Of course they
could blacklist eth1394, but then ieee1394 wrongly advertized IP-over-
1394 capability to the FireWire bus.
Therefore
- remove the offending kernel config option
IEEE1394_CONFIG_ROM_IP1394,
- let eth1394 add the ROM entry by itself, i.e. only after eth1394 was
loaded.
This fixes http://bugzilla.kernel.org/show_bug.cgi?id=7793 .
To emulate the behaviour of older kernels, simply add the following to
to /etc/modprobe.conf:
install ohci1394 /sbin/modprobe eth1394; \
/sbin/modprobe --ignore-install ohci1394
Note, autoloading of eth1394 when an _external_ IP-over-1394 capable
device is discovered is _not_ affected by this patch.

This is a coding style touch-up for ieee1394's handle_incoming_packet().
A preprocessor macro contained hardwired variable names and, even worse,
the 'break' keyword. This macro is now unrolled and removed.
Also, all 'break's which had the effect of a return are replaced by
return. And a FIXME comment is brought up to date.

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:

(It was actually 2 kB, not 8 kB.)
> - Fix hpsb_allocate_and_register_addrspace() to not allocate space
> on top of already allocated space.
> - Fix problems in csr1212.c filling ConfigROM images when extend

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.
