This allows control over what percentage of
the congestion window can be consumed by a
single TSO frame.

The setting of this parameter is a choice
between burstiness and building larger TSO
frames.

Basic cleanup - replace untyped/wrongly typed "dev->base_addr" with
use of a strongly typed "ioaddr".

Fixed up resulting mii_delay() search-and-replace error noticed by
Andrey Klochko.

fix a problem in pfm_check_task_state() and pfm_task_incompatible()
which was caused by the introduction of the new TASK_TRACED state.
Tool would fail to attach to a process,i.e., PFM_LOAD_CONTEXT would
fail. With the fix perfmon now accepts to operate on tasks which are
in either TASK_STOPPED or TASK_TRACED state. The problem was tracked
down by Alex Williamson from HP who also submitted the patch.

Played a bit with overcommit the past hour.

Am not entirely satisfied with the no overcommit mode 2 -
programs segfault when the system is close to that boundary.
So, instead of the somewhat larger patch that I planned to send,
just symbolic names for the modes.

I didn't have ISDN builds on in my tree for some reason hence missing these
two from the tidy ups at the end. Marcel Holtmann also came up with the
same fixes although I didnt find that email until I did these.

This only causes a problem in the -mm tree now, but Zou Nan hai and
Shaohua Li sent me this fix so that SMP systems compiled with the

If we read and write the PROM chips at the same time, as might happen at boot
when salinfo extracts MCA records and a user is checking the PROM revision
in /proc/sgi_prominfo, an MCA might occur, since the PROM chips can't be
accessed that way.  This patch fixes the problem for systems with new PROMs
(>= 3.50) by using the SAL to do PROM reads.

- Export tcp_trim_head() and call it directly from
  tcp_tso_acked().  This also fixes URG handling.

- Make tcp_trim_head() adjust the skb->truesize of
  the packet and liberate that space from the socket
  send buffer.

- In tcp_current_mss(), limit TSO factor to 1/4 of
  snd_cwnd.  The idea is from John Heffner.

Bartlomiej Zolnierkiewicz wanted to remove the "cbio" structure
from struct request.  Unfortunately, MMC was using the same
"workaround" as IDE to walk the BIO list.  With this change, we
stop using "cbio" and instead use proper scatter-gather lists.

This patch adds a 10 ms delay in the power up loop. Some cards fail
to power up in time without it.

Pierre Ossman reported a problem where his cards do not correctly
initialise with the current MMC implementation.  However, if we
tell the card to go back to the idle state between probing the
supply voltage and telling the card about the chosen voltage, his
cards work - and we don't seem to upset existing cards.

This allows users to provide a fixed major number - early 2.4 MMC
drivers used block device major 60, which is "local/experimental
use"

Use msleep_interruptible() instead of schedule_timeout() to
guarantee the task delays as expected.

It's a rather bad idea to have psa-regs.h included all the time.
It's rather large and likely to create namespace clashes, as well
as slowing down the build unnecessarily.

Better include it explicitly where it is actually needed.

Let's move GPIO setup into the board specific hw init functions.

The PXA2xx often has many different GPIOs that can be used for
a given alternate function and the good one to use is hardware
dependent.  For example, Lubbock and Mainstone are not using all
the same GPIOs for PCMCIA signals.

Remove the code that jumps to physical offset in head-xscale.S for IOPs that was fixing a legacy redboot problem. The issue no longer exists it seems and it's breaking the compilation anyways. Removed.
