Subject: [PATCH]: Compress hibernation image with LZO (in-kernel)

This patch speeds up hibernate/thaw operations (in kernel ones) by
compressing the pages using LZO. Tests on my ThinkPad T510 show that
hibernation times can be cut by the factor of about 4 for an image of
around 1 GB (from about a minute down to about 15 seconds).

I'm not really familiar with kernel internals, so many of the things in
this patch could be very, very wrong. But go easy - this is essentially
the first time I've attempted something like this.

PS. I'm not on the list, so please CC me if you'd like to contact me.
