iap10@freefall.cl.cam.ac.uk cab0ef71c3 Improved "PGDs must be under 4GB" handling for PAE.

iap10@freefall.cl.cam.ac.uk 8b1b30d3cb Give each domain some memory below 4GB. This solves the "PGD's must be below 4GB" for the initial page tables. I'm not sure we'll stick with this approach, but this is good enough for the time being. 
PAE should be a *lot* more robust on systems that actually have more than 4GB thanks to all the various patches that went in today. I find it astounding that it ever appeared to work at all!

kaf24@firebug.cl.cam.ac.uk aab6fa579e The attached patch adds a new dom0_op, DOM0_GETDOMAININFOLIST. This 
operation allows retrieval of the domain info structures for all domains
in one hypercall.

Using a small test program, on a system with 97 domains with
non-contiguous domain IDs, I found that with this hypercall I could
retrieve the full array of info structures 12840 times per second, an
improvement from 2380 times per second with the DOM0_GETDOMAININFO op.

The patch also adds a libxc wrapper for this new hypercall.
