Revision c3442e296517aee733d62fc3fe03211598902c7d authored by Ingo Molnar on 05 March 2007, 13:46:30 UTC, committed by Linus Torvalds on 05 March 2007, 16:34:25 UTC
CONFIG_PARAVIRT broke old glibc bootup: it silently turned off the selectability of CONFIG_COMPAT_VDSO and thus rendered distro kernels unbootable on old-style VDSO glibc setups. the proper solution is to keep COMPAT_VDSO available - if a hypervisor needs any modification of that concept then we'll judge those changes in full context, once those changes are submitted.
