Yesterday vger and ioremap

Yesterday vger and ioremap

[Benjamin Herrenschmidt]

Hi !

vger tree from yesterday gives me tons of warnings of the style:
"__ioremap(). Overlap detected and handled for PA xxxxxxx VA xxxxxxxx"
when booting.

Apparently, the kernel works fine, PA seems to always be equal to VA, and
apparently, this concerns all addresses on the Apple asic (mac-io on the
G3), at f30xxxxx. 
Since this is mapped with a BAT, I'm wondering if this could be a
conflict between new ioremap changes and BAT mapping ?

(I didn't look at actual source code changes, the problem seems to be
harmless, just those messages in the console).

I was wrong, actually, the kernel  doesn't work, looks like IP or
ethernet is just dead. I don't have enough time to look at this now
(using bmac ethernet on a desktop G3, I didn't test another machine yet).

The ioremap problems should be fixed now.  Please try it again.  If it
isn't fixed let me know.

} vger tree from yesterday gives me tons of warnings of the style:

} when booting.

Those were just debugging messages until the ioremap changes were done.
