[Xen-devel] [PATCH 0/3] xen: Fix oops when mapping/unmapping addr above 1Gb

[Mark McLoughlin <markmc@xxxxxxxxxx>]

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.
