[Qemu-devel] [PATCH 0/2] vdso for x86_64-linux-user

[Richard Henderson]

This is a refresh of a patch I wrote in 2010, and have re-posted every
6 months thereafter.  To my knowledge, it has never been reviewed.

It supplies a replacement for the required x86-64 vdso.  Anyone trying
to emulate x86_64-linux on a host other than same will quickly run into
the lack of a gettimeofday syscall, which glibc assumes is always
provided by the vdso.
