Subject[PATCH 0/5] Collected vdso/vsyscall fixes for 3.1
Date
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.
