ieee1394: eth1394: don't autoload by hotplug when ohci1394 starts

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.

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.

the memory which they point to has to be.

The member "struct sbp2_command_orb command_orb" has to be aligned on
4 bytes boundary which is guaranteed because it contains u32 members.

The member "struct sbp2_unrestricted_page_table scatter_gather_element",

according to the SBP-2 spec.  This is not a requirement for FireWire
controllers but could be expected by SBP-2 targets.

I see no need to align the members command_orb and
scatter_gather_element on CPU cacheline boundaries.  It could have
performance benefits, but on the other hand sbp2 has a somewhat wasteful

elements.)

Note, before as well as after the patch, the code relies on the
assumption that memory alignment in the virtual address space is
preserved in the physical address space after DMA mapping.

sis900: Allocate rx replacement buffer before rx operation

Just found a hole in my last patch.  It was reported to me that shortly after we
integrated this patch.  The report was of an oops that took place inside of
netif_rx when using the sis900 driver.  Looking at my origional patch I noted
that there was a spot between the new skb_alloc and the refill_rx_ring label
where skb got reassigned to the pointer currently held in the rx_ring for the
purposes of receiveing the frame.  The result of this is however that the buffer
that gets passed to netif_rx (if it is called), then gets placed right back into
the rx_ring.  So if you receive frames fast enough the skb being processed by
the network stack can get corrupted.  The reporter is testing out the fix I've
written for this below (I'm not near my hardware at the moment to test myself),
but I wanted to post it for review ASAP.  I'll post test results when I hear
them, but I think this is a pretty straightforward fix.  It just uses a separate
pointer to do the rx operation, so that we don't improperly reassign the pointer
that we use to refill the rx ring.
