Re: [Xen-devel] [PATCH 0/2] Add hugetlb support for PV

Here is a set of small patches that enables hugetlb on PV machines. They are
against xen-unstable and linux-2.6.18-xen.
The patches are specifically for x86_64.
I originally had these patches working back in May, but recently for some
reason my machine now refuses to boot the baseline xen-unstable, so I've been
unable to verify them. However, they should still work.
Comments, bug reports, and suggestions are welcome.
I must be missing something, but I can't see how you guarantee the
super pages to be contiguous in machine memory. And even if you did,
the hypervisor would still need to do accounting on all the 4k portions
a super page consists of when it gets mapped/unmapped.
Yeah, I'm pretty sure there has to be a lot more to it than that.
