Description Chris Lalancette 2007-10-08 13:41:27 EDT
Description of problem:
Xen 3.1.1 has a couple of changesets that fix some possible bugs in the x86_64
vsyscall page.  They are in xen-3.1-testing.hg, c/s 15092 and 15125.  We should
determine whether we want/need these changesets.
Comment 1 RHEL Product and Program Management 2008-02-01 17:40:04 EST
This request was evaluated by Red Hat Product Management for
inclusion, but this component is not scheduled to be updated in
the current Red Hat Enterprise Linux release. If you would like
this request to be reviewed for the next minor release, ask your
support representative to set the next rhel-x.y flag to "?".
Comment 2 Miroslav Rezanina 2009-04-15 09:26:28 EDT
Applying these two changesets cause only cosmetic change - instead of code mk_kernel_pgd(address) is used its expansion __pgd(address | _TABLE_PAGE). There can be reason to use only c/s 15092 that add _PAGE_USER flag to parameter address.
Comment 3 Chris Lalancette 2009-11-24 16:26:59 EST
I'm going to close this.  It looks cosmetic, and if we do decided to do vsyscall, it's going to require a lot more than this.  We have other bugs open to cover enabling Xen vsyscall.
