Subject: [PATCH 0/3] xen: Fix oops when mapping/unmapping addr above 1Gb
Date: Fri, 28 Mar 2008 16:38:14 +0000 [thread overview]
Message-ID: <1206722297-11763-1-git-send-email-markmc@redhat.com> (raw)
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.
