Hi, This series corresponds do older patches in the paravirt series that was neither already applied, nor I will touch again. In general, they do not touch code that can be unified (at least, without being the unification a big problem on its own). They passed through this list a lot of times, so I feel them ready for inclusion, unless someone opposes. As with the other patches, they apply to

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 :) [1]
