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. r~ Richard Henderson (2): linux-user: Build vdso for x64. linux-user: Load a VDSO for x86-64.
