Re: [PATCH] powerpc vdso updates

Hi Ben,

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.

Im getting this on the current powerpc git tree:

arch/powerpc/kernel/signal_32.c: In function 'handle_rt_signal':
arch/powerpc/kernel/signal_32.c:763: error: request for member
'vdso_base' in something not a structure or union

It looks like we use the mm_context_t definition in asm-ppc/mmu.h for
32bit ARCH=powerpc builds and need vdso_base there too.
