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). Konrad, could you could test these on Xen and run 'test_vsyscall test' [1]? I don't have a usable Xen setup. Also, I'd appreciate a review of patches 4 and 5 from some Xen/paravirt people.
