[PATCH] powerpc vdso updates
This patch cleans up some locking & error handling in the ppc vdso and moves the vdso base pointer from the thread struct to the mm context where it more logically belongs. It brings the powerpc implementation closer to Ingo's new x86 one and also adds an arch_vma_name() function allowing to print [vsdo] in /proc/<pid>/maps if Ingo's x86 vdso patch is also applied.
