Peter Anvin <hpa@xxxxxxxxxxxxxxx> CommitDate: Wed, 10 Aug 2011 18:55:48 -0500 x86-64: Wire up getcpu syscall getcpu is available as a vdso entry and an emulated vsyscall. Programs that for some reason don't want to use the vdso should still be able to call getcpu without relying on the slow emulated vsyscall. It costs almost nothing to expose it as a real syscall. We also need this for the following patch in vsyscall=native mode.
