Subject: Fix VMI and COMPAT_VDSO
From: Zachary Amsden <zach@xxxxxxxxxx>
VMI is broken under COMPAT_VDSO, as Xen and other non hardware assisted
hypervisors will be. I have been working on a fix for this which works for
older glibcs that panic when the new relocatable VDSO is used. However, I
believe at this time that the fix is going to be too radical to consider at
this stage in the release of 2.6.21. We don't expect this config option to
be turned on by vendors for new distributions, so at this point we are
willing to drop support for it when VMI is compiled in, and work on a patch
for 2.6.22 which more fully addresses the problem.
