    Subject: [patch] paravirt: re-enable COMPAT_VDSO
    From: Ingo Molnar <mingo@elte.hu>

    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.

    Map the VDSO to the predictable old-style address too.
