In Fedora rawhide we're currently seeing oopses whenever a processes dlopen()s a library which prelink() has previously relocated above 1Gb. Some more details at:

The issue seems to be that during xen_pgd_pin(), we only pin PTE pages, but xen's release_pmd() tries to unpin PMD pages too.

The following series of patches is against the latest x86 tree.

thanks, i've picked them up to get them tested - but it would be nice to have an ack from Jeremy as well. This seems like v2.6.25 material as well, right?

Didn't I reply? Anyway, the patch looks good. It's definitely 2.6.25 material; its fallout from the changes I did to dynamically allocate/deallocate pmds rather than always do them with the pgd.
