Subject[patch] paravirt: re-enable COMPAT_VDSO
Subject: [patch] paravirt: re-enable COMPAT_VDSO
From: Ingo Molnar <>

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.
