[PATCH] lguest: clean up some l"references .init.text" warnings
Thanks to Andrew for pointing these out.
This patch moves the parvirtprobe section into .init.data: it's only
used in very very early boot, and for similar reasons, puts
lguest_maybe_init and lguest_memory_setup in init.text.
As well as fixing some warnings, this frees up a tiny bit more memory.

[PATCH 0/7] Modify lguest32 to make room for lguest64
Hi all,
I've been working on lguest64 and in order to do this, I had to move
a lot of the i386 specific out of the way. Well, the lguest64 port
is still not ready to display, but before Rusty makes too many changes
I would like this in upstream so I don't have to keep repeating my
changes :-)
So this patch series moves lguest32 out of the way for other archs.
