Re: [PATCH 6/6] Add 32 bit VDSO support for 32 and 64 bit kernels

The Kconfig text for COMPAT_VDSO suggests that glibc versions prior to
2.3.3 may have relied on the fixed address. I can't find anything in the
libc revision history to explain that (AFAIK the code always used
AT_SYSINFO* since it started using the vDSO at all), but it might have been
something less obvious. Someone like Jakub might recall the details.
