here is the fix.

The current code allocating the DART has a couple of bugs, first
it's called on all machines including the ones who have no DART
(oops), and then it tries to access the device-tree using the
"of_chosen" pointer before it was initialized.

The enclosed patch fixes these.

Looks like we never needed them, since that bug has been there forever,
I didn't get the right base for the IO cycles on the G5 host bridge
in the first place (I probably misinterpreted some OF forth code or
something like that).

No problems reported other than Linus typo in an unbuildable driver from
the last one.

This one adds tty_ldisc_flush and also makes tty_wakeup do the queue
wake as discussed with Paul.  I've then propagated these functions
through all the drivers.  This means most drivers don't know about the
ldisc locking and instead call generic functions that look after it. 
The result is the removal of a lot of duplicate code both for ldisc
referencing and historical code for handling tty ldisc wakeup semantics.

A nice side effect is that by adding versions of the two helpers we can
switch most of the drivers over before changing the core tty code if
preferred.

This patch moves the following files in /proc:
	/proc/net/rt_cache_stat 	/proc/net/stat/rt_cache
	/proc/net/ip_conntrack_stat	/proc/net/stat/ip_conntrack
	/proc/net/arp_cache_stat	/proc/net/stat/arp_cache
	/proc/net/clip_arp_cache_stat	/proc/net/stat/clip_arp_cache
	/proc/net/dn_neigh_cache_stat	/proc/net/stat/dn_neigh_cache

This allows a generic statistics tool to scan for all available statistics
by doing readdir(2) on /proc/net/stat

It also adds a special first 'template' line to rt_cache and ip_conntrack
in order to facilitate compatibility once somebody adds new fields to the
output lines.

WARNING: 
	This breaks existing rtstat.c and ctstat.c userspace programs
	(hopefully for the last time).  rtstat is non-existant or broken in
	major distributions anyway, and ctstat is too new for any distros
	having it picked up.  Therefore, we justify this breakage.

A new unified statistics tool for routing cache, connection tracking and
neighbour cache is under development and will be included with iproute2.

There's an issue with bio_uncopy_user() in that it expects ->bv_len to
be untouched from io submission to io completion, which it wont be for
some transfer lengths on some hardware. So we end up not copying all the
data back to user space, not so good. This patch adds a bio_map_data
local structure to track the io_vec.
