Here's an additional patch for ipvs, which also mangles packets via 
netfilter and was previously depending on the checksum helper in 
nf_hook_slow().

assorted minor bits in drivers/* - all independent, but there's
some limit to splitting stuff...

several pointers in ioctl structures marked as userland ones.

And that's it with this patchset.  A couple more of those and we'll
be done with the noise warnings ;-)

s2io.c: bogus initializer ({{"a"},{"b"}} has too many braces for
two-dimensional array of char - strings are arrays themselves).

de4x5.h: missing __user on a pointer in ioctl structure. 

airo.c: cleaned up and fixed procfs ->read() and ->write()

osst.c, st.c, scsi_debug.c annotated.

selinuxfs.c annotated

	b44.c: ->ioctl() is broken, since it uses &ifr->ifr_data instead of
ifr->ifr_data itself.  Surprise, surprise, copy_from_user() on that address
doesn't do any good...

	baycom_epp.c: does get_user() of the first word of structure, then
immediately does copy_from_user() on the entire thing and completely ignores
the value read by get_user() (it uses the same value in copied structure
instead).  Bogus get_user() call removed.

->ifr_data users annotated.

Some code that is used on iSeries (do_hash_page_DSI in head.S) was
clearing the RI (recoverable interrupt) bit in the MSR when it
shouldn't.  We were getting SLB miss interrupts following that which
were panicking because they appeared to have occurred at a bad place.
This patch fixes the problem.  In fact it isn't necessary for
do_hash_page_DSI to do anything to RI, so the patch changes the code
to not set or clear it.

In a nutshell, skb checksum mangling has been removed from
nf_hook_slow() and pushed up to whatever really needs to do it.

Namely:  NAT, ip_fw_compat, ipt_TCPMSS, IPSec transforms.

skb_checksum_help() has been changed to perform an skb_copy() if needed 
(e.g. the original problem case where bcast/mcast was cloning packets for 
transmission over loopback, changing ip_summed).

Because of the above, the output path has been modified to take into 
account the fact that an skb may need to be changed in some places.  There 
are some minor changes in the routing code to take care of the now 
different input and output function prototypes.  The ipv6 fragmentation 
code has been modified to detect a changed skb.

The rest of the patch (probably the bulk of it) is simply the result of 
changing to double skb pointers.

I've tested this with ipv4, ipv6, ipsec (including xfrm bundles), NAT and 
the original DHCP test case.  Everything seems to be working ok.

net/bridge partially annotated.

There are nasty problems with net/bridge/netfilter/* and they'll need to
be dealt with at some point - it mixes kernel and userland pointers a
lot and while it seems to avoid obvious breakage, it's not a nice code.

econet partially annotated.

It's still badly broken - it mixes userland and kernel chunks in the
same iovec, then does set_fs(KERNEL_FS) and sends that to
sock_sendmsg().  Do we still want to support that protocol family,
anyway?
