This fixes various problems that cropped up with the vdso patches.
- Patch 1 fixes an information leak to userspace. - Patches 2 and 3 fix the kernel build on gold. - Patches 4 and 5 fix Xen (I hope). - Patch 6 (optional) adds a trace event to vsyscall emulation. It will make it easier to handle performance regression reports :)
