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. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> diff -r ecec388180b2

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. -- Steve

Hi all, These are the patches I'm planning to submit for 2.6.24. Comments gratefully accepted. Along with the usual cleanups and improvements are Jes' de-i386-ification patches, and a new "virtio" mechanism designed to be shared with KVM (and hopefully other hypervisors). Cheers, Rusty.
