seq_file support for /proc/net/atm/lec:
- lec_info(): seq_printf/seq_putc replaces sprintf;
- traversal of the lec structure needs to walk:
  -> the lec interfaces
     -> the tables of arp tables(lec_arp_tables);
        -> the arp tables themselves
     -> the misc tables (lec_arp_empty_ones/lec_no_forward/mcast_fwds)

  Sum up of the call tree:
  atm_lec_seq_start()/atm_lec_seq_next()
  -> atm_lec_get_idx()
     -> atm_lec_itf_walk() (responsible for dev_lec/dev_put handling)
        -> atm_lec_priv_walk() (responsible for lec_priv locking)
           -> atm_lec_arp_walk()
              -> atm_lec_tbl_walk()
           -> atm_lec_misc_walk()
              -> atm_lec_tbl_walk()

  Each of the dedicated functions follows the same convention: return NULL
  as long as the seq_file cursor hasn't been digested (i.e. until < 0).
  Locking is only done when an entry (i.e. a lec_arp_table) is referenced.
  atm_lec_seq_stop()/atm_lec_itf_walk()/atm_lec_priv_walk() are responsible
  for getting this point right.
- module refcounting is done in atm_lec_seq_open()/atm_lec_seq_release();
- atm_lec_info() is removed.

Chas's suggestions applied since last version:
- atm_seq_lec_fops renamed to lec_seq_fops;
- change in state handling: it wasn't correctly set to its reset value
  after a complete interface walk;
- lec_arp_get_status_string() bugfix.

seq_file support for /proc/net/atm/arp:
- svc_addr/atmarp_info(): seq_printf/seq_putc replace sprintf and friends;
- arp_getidx/arp_vcc_walk() take care of the usual seq_file cursor
  positionning: they both return NULL until the cursor has reached its
  position. struct atm_arp_state is updated accordingly;
- arp_seq_{stop/start} are responsible for clip_tbl_hook (un)locking;
- module refcounting is done in arp_seq_open()/arp_seq_release();
- atm_lec_info() is removed.

Chas's suggestions applied since last version:
- atm_arp_xxx renamed to arp_xxx;
- atm_seq_arp_fops renamed to arp_seq_fops.

Chas didn't ask for it but I renamed arp_vc_walk to arp_vcc_walk.

seq_file support for /proc/net/atm/vc:

Same comments as for pvc and svc.

Extra Chas's suggestion applied since last version:
- atm_vc_xxx renamed to vcc_xxx.

seq_file support for /proc/net/atm/svc:

Exactly same comments as pvc. Just s/p/s/

seq_file support for /proc/net/atm/pvc:
- pvc_info(): seq_printf/seq_putc replaces sprintf;
- atm_pvc_info() removal;
- the vc helpers (vcc__seq_xxx) do the remaining work.

Chas's suggestions applied since last version:
- atm_pvc_xxx renamed to pvc_xxx
- atm_seq_pvc_fops renamed to pvc_seq_fops

Helpers for seq_file conversion of proc/atm/{pvc/svc/vc}:
- struct vcc_state keeps
  1) the struct sock from which the current struct atm_vcc is deduced
  2) the family to which must belong the vcc (PF_ATM{SVC/PVC/any})
  3) the availability of clip module
- vcc_seq{start/stop} are responsible for vcc_sklist locking
- __vcc_seq_open and vcc_seq_release take care of get/put for the clip module.

Chas's suggestions applied since last version:
- atm_vc_xxx renamed to vcc_xxx
- atm_vc_common_seq_open renamed  __vcc_seq_open (future name clashes
  avoidance)

seq_file conversion for proc/atm/devices:
- code inspired from seq_file use in net/core/dev.c;
- atm_dev_lock taken/released in atm_dev_seq_{start/stop};
- add a helper CREATE_SEQ_ENTRY() similar to CREATE_ENTRY() (both are removed
  once conversion is done).
- atm_dev_seq_{start/stop/next} done in net/atm/resource.[ch] to ease
  future handling of atm_devs and locking structure (per Chas suggestion)

Thish fixes Suparna's fsx and aio-stress and Dave Olien's concurrent
mke2fs problems.

It moves the hash adding into as_add_request.  This fixes a small bug
where a request could be added to the merge hash after being put on the
dispatch list. 

It also moves responsibility for handling rbtree aliases (requests with
the same start sector) out of as_add_arq_rb and into its caller.  This
cleans up a layering problem which was causing the state machine to go
silly.  Now instead of forcing the alias out onto the dispatch list, we
chain the new request behind it, and they get sorted out at dispatch
time.

The PS/2 ESDI driver has some problems: a couple of typos on the modular
side and misuse of module_init():

A colleague reported that the keyboard of his brandnew laptop
is dead under 2.6 while 2.4 works.

Now I once wrote

  In order to avoid interference between scancode sequences
  or mouse packets and the reponses given to commands,
  the keyboard or mouse should always be disabled before
  giving a command that requires a response, and probably
  enabled afterwards. Some keyboards or mice do the disable
  automatically in this situation, but still require an
  explicit enable afterwards. 

(http://www.win.tue.nl/~aeb/linux/kbd/scancodes-9.html)

This is what happens on this laptop. The routine atkbd_probe()
probes for a keyboard, and after detecting it, enables it.
But immediately afterwards the routine atkbd_set_3() reads
the current scancode set and sets the desired set, and as a
side effect of these commands, the keyboard gets disabled again.

Thus, the keyboard enable must be moved after all command sending
has been done.

Now that I patch this area anyway: we are almost always in
scancode set 2 but send the ATKBD_CMD_SETALL_MB command
that only works in scancode set 3. At best this is useless.
At worst it confuses the keyboard. So, I put this command
in a separate routine and call that only when we really
are in scancode set 3.

Combine the two initialisation functions, allow SA1111 to be built
as a module, and remove a redundant SA1111 function prototype.

Make it work ;)

This the the resubmit of the flash partition changes for SIMpad.



Two versions one for cramfs one for all jffs2 and also the SIM has two banks instead of one even if they're next to each other...

devfs_handle is not used any more.

My fault.  Fix for broken aarp.c which got an extra closing parenthesis.

<linux/interrupt.h> uses barrier() but does not include <linux/kernel.h>.

Whitespace cleanup (mostly deleting trailing whitespace).

This patch introduces a 1GB stack size limit for stack-grows-up (ie
PA-RISC), as discussed previously.
