With this LLC_CONN_PRIM and friends went to the death row, next
patch will introduce llc_establish_connection, turning on the
electric chair switch for LLC_CONN_PRIM et al.

With this PF_LLC is tightly integrated with the core and that is a
good thing 8)

. kill llc_ui_opt, the only non-duplicated bit is struct sockaddr_llc
  and this now lives in llc_opt
. remove debug code from llc_sk_alloc/free (previously llc_sock_alloc/free)
. the skbs allocated for event processing don't need to have any payload
  at all, just the skb->cb is enough, so remove the bogus 1 from alloc_skb
  calls
. llc_conn_disc put on death row
. llc_process_tmr_ev callers have to hold the socket lock
. the request functions in llc_if.c doesn't hold the socket lock anymore
  its up to its callers on the socket layer (llc_sock.c)
. llc_sk_alloc now receives a priority for sk_alloc call and is the
  only way to alloc a new sock (from llc_mac and llc_sock, bottom and top)
. added the traditional struct sock REFCNT_DEBUG support for llc
. llc_sock was simplified and is on the zen route to cleanliness, wait for
  the next patches, it'll shrink a lot when I zap all the crap (as in
  not needed) list handling, using the existing list maintained in
  struct llc_sap for that, probably splitting it in two, one for listening
  sockets and other for (being) established ones.  Ah, and the sap->ind
  and sap->req and friends will die.

All of those functions cannot possibly fail, so there is no
point in always returning 0. I'll probably turn all of them
into inlines in the future too.

. now llc_ui_accept uses llc_ui_wait_for_data (llc_ui_recvmsg probably
  will use it too, we'll see)
. all the llc_ui_wait_for_ now receive the timeout in jiffies, not
  in seconds
. use sk_rcvtimeo()
. release_sock before going to sleep in the llc_ui_wait_for functions
. llc_ui_release has to get the socket lock

On the road to kill all prims, llc_prim_data bits the dust, now
the core queues the data directly and takes care of the conf semantics,
i.e. waking up the upper layer when the confirmation arrives. Maybe I'll
have to put more info on skb->cb for conf and ind, but for PF_LLC this is
enough for now. Have to check NetBEUI tho. But we can always add back
removed features, better than having features that nobody uses :-)

Rename llc_data_req_handler with llc_build_and_send_pkt, following my
plan to have LLC look more like TCP/IP and to slowly remove all the ugly
prim types and sap->{req,ind,conf}.

No problems with Appletalk up to now as it only uses UI and I'm up to
now only concentrating on connection mode, so that we can remove all
the duplicated work in core and PF_LLC.

also remove tests against SOCK_SEQPACKET, it is not supported
in llc_ui_create.

  properly handle multiple upper layer protocols

. dprintk already puts the log level
. fix some comments to match new behaviour

It is nice that blkdev_ioctl calls blk_ioctl itself, but unfortunately
it does that only if driver's ioctl returns -EINVAL - and IDE returns
-EIO :-(

Patch below is tested for disks - I do not have IDE floppy nor IDE tape.

of something arch-dependent and usually less. 

We may want to do value limiting in generic_fillattr() if people
end up caring.

This is the pid-max patch, the one i sent for 2.5.31 was botched.  I
have removed the 'once' debugging stupidity - now PIDs start at 0 again.
Also, for an unknown reason the previous patch missed the hunk that had
the declaration of 'DEFAULT_PID_MAX' which made it not compile ...

This contains Daniel's suggested fix that allows a parent to
PTRACE_ATTACH to a child it forked.  That fixes the incorrect BUG_ON()
assert that Ogawa's patch was intended to fix, and we thus undo Ogawa's
patch.

I've tested various ptrace uses and they appear to work just fine.

We want do so on all architectures for consistency, and i386 will need
the preprocessing soon anyway.

My previous patch added procs i2c_fill_inode and i2c_dir_fill_inode that
Al Viro deemed unnecessary.  i2c developers are in contact with Al to
get the latest scoop.  Meantime lets reverse the change before he flies
off at me about procfs abuse.

Tthis one seems to have been around since 2.5.31 and nobody has fixed it
yet...

BTW, while merging aio from 2.5 to 2.4 and fixing and porting the libaio
(in particular thanks to one of Ben's testcases that was checkin for
this specific case) I found this bug in 2.5

	OK, before the next bunch of gendisk merges, here comes a couple
of 2.5 IDE cleanups.

	a) exclusion between rereading partition tables and open() is done
in fs/block_dev.c these days, so homegrown one in ide.c is redundant - that
code _never_ blocks now.  Removed, just as it had been done with counterparts
in other drivers.

	b) blk_ioctl() calls are done in blkdev_ioctl() now; driver doesn't
need to handle them.  Again, removed as it had been done in all other drivers.

if a new edge happened while we were still processing the previous
one.

Then, if a _third_ edge came in, it would actually cause a reentrant
irq handler invocation, because the original INPROGRESS bit was now
lost.

This was actually seen on IDE in PIO mode.

Unify the PCI device ID constants used by AGP with the normal Linux ones.

create_elf_tables in fs/binfmt_elf.c now sets up the list of aux table
entries in a buffer on the kernel stack before copying it to the user
stack.

Unfortunately, while the buffer is big enough for most architectures, it
isn't big enough on PPC, which uses 5 extra aux table entries (put on
with ARCH_DLINFO).  The following patch increases the buffer to be big
enough for PPC.  (Note that each aux table entry uses two elements of
the elf_info array.)

to the bottom of the aux table.

The BK merging was a little too smart for the conflicting changes.
Add back what we lost with the last changeset.

We need to sync the blockdevice mapping at umount although sync_blockdev
already does it as we need to make sure everything hits the disk before
we mark the superblock clean.
