Patch from Lennert Buytenhek

The ixp2000 defconfigs are among the few that do not enable module
support by default.  I keep enabling module support by hand for every
new kernel version, so let's just make this change upstream.

Patch from Lennert Buytenhek

The IXP2000 has four timers, but if we're on an A-step IXP2800, timer
2 and 3 don't work.  We need two timers for timekeeping (one for the
timer interrupt and one for tracking missed jiffies), so on early
IXP2800s we have no other choice but to use timer 1 and 4 for that,
but on all other IXP2000s we'd rather leave timer 4 free since that's
the only timer we can use for the watchdog.
So, on buggy IXP2000s (i.e. the A-step IXP2800) we use timer 4 for
tracking missed jiffies, and on all all non-buggy IXP2000s (i.e.
everything but the A-step IXP2800) we use timer 2.
On a pre-production IXP2800, this patch should print these messages
on boot:
	Enabling IXP2800 erratum #25 workaround
	Unable to use IXP2000 watchdog due to IXP2800 erratum #25
On any non-buggy IXP2800 (as well as on IXP2400s) you shouldn't see
anything at all, and the watchdog should be usable again.

A fairly recent platform requirement states that the OS must clear the
whole TCE table at setup time, in case firmware left any active
mappings in it.  Without this initialization, dynamic bus removes can
fail.  Firmware rejects these requests if active mappings still exist 
for a slot that has been deallocated by the OS.

When DMA bounce buffers were unmapped and the data was memcpy'd to
the original buffer, we were not ensuring that the data was written
to RAM.  This means that there was the potential for page cache
pages to have different cache states depending whether they've been
bounced or not.

This patch changes the type of the third parameter 'length' of the 
raw_send_hdrinc() function from 'int' to 'size_t'.
This makes sense since this function is only ever called from one 
location, and the value passed as the third parameter in that location is 
itself of type size_t, so this makes the recieving functions parameter 
type match. Also, inside raw_send_hdrinc() the 'length' variable is 
used in comparisons with unsigned values and passed as parameter to 
functions expecting unsigned values (it's used in a single comparison with 
a signed value, but that one can never actually be negative so the patch 
also casts that one to size_t to stop gcc worrying, and it is passed in a 
single instance to memcpy_fromiovecend() which expects a signed int, but 
as far as I can see that's not a problem since the value of 'length' 
shouldn't ever exceed the value of a signed int).

This patch changes the type of the local variable 'i' in 
raw_probe_proto_opt() from 'int' to 'unsigned int'. The only use of 'i' in 
this function is as a counter in a for() loop and subsequent index into 
the msg->msg_iov[] array.
Since 'i' is compared in a loop to the unsigned variable msg->msg_iovlen 
gcc -W generates this warning : 

net/ipv4/raw.c:340: warning: comparison between signed and unsigned

Changing 'i' to unsigned silences this warning and is safe since the array 
index can never be negative anyway, so unsigned int is the logical type to 
use for 'i' and also enables a larger msg_iov[] array (but I don't know if 
that will ever matter).

This patch gets rid of the following gcc -W warning in net/ipv4/raw.c :

net/ipv4/raw.c:387: warning: comparison of unsigned expression < 0 is always false

Since 'len' is of type size_t it is unsigned and can thus never be <0, and 
since this is obvious from the function declaration just a few lines above 
I think it's ok to remove the pointless check for len<0.

This patch silences these two gcc -W warnings in net/ipv4/raw.c :

net/ipv4/raw.c:517: warning: signed and unsigned type in conditional expression
net/ipv4/raw.c:613: warning: signed and unsigned type in conditional expression

It doesn't change the behaviour of the code, simply writes the conditional 
expression with plain 'if()' syntax instead of '? :' , but since this 
breaks it into sepperate statements gcc no longer complains about having 
both a signed and unsigned value in the same conditional expression.
