    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.
