Two 32bit power3/4 build-failure patches ...

Hello,

I have here two 32bit power[34] build failure patches that the debian kernels
has been using for some time, and which i think i did post here in the past,
but it doesn't seem to be applied.

Well, those are 32 bit issues, and debian doesn't build anymore 32bit kernels
of those flavours, but i guess it may be possible that some random user wants
to build them, so it would be nice if they could be included upstream.

Friendly,

Sven Luther

I think we'll be dropping 64 bits CPU support for 32 bits kernel anyway.

Ok, so i just drop these patches them, but i guess you can still apply them,
don't you think ? They can cause no problem, and may be useful until 32bit
kernels are dropped.
