Subject[PATCH 0/3] xen: Fix oops when mapping/unmapping addr above 1Gb
Date

Hi,
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:

https://bugzilla.redhat.com/436453

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.

Cheers,
Mark.
