SubjectRe: [patch] i386, vdso=[0|1] boot option and /proc/sys/vm/vdso_enabled

no, i think that conclusion is wrong. The FC1 glibc and vdso problems
*when mixing a FC2 kernel with a FC1 glibc* were due to exec-shield
enforcing non-exec for the vdso.

this bug has nothing to do with nonexec restrictions. [ Also, this all
was _years_ and hundreds of bugs ago, when upstream's position was still
a cocky "who the hell needs protection against overflows" and "go away
with this non-exec crap" so we were pretty much alone trying to
introduce those features. So any suggestion of intention on our part
would be quite unfair. ]
