Hi Masahiro,

Since commit bce74491c300 ("powerpc/vdso: fix unnecessary rebuilds of
vgettimeofday.o"), "make ARCH=powerpc clean" does not clean up the
arch/powerpc/kernel/{vdso32,vdso64} directories.
Use the subdir- trick to let "make clean" descend into them.

This patch make me think about one thing I would have liked to do, but I
don't know Makefiles well enough to be able to do it. You could probably
help me with it.
vdso32 and vdso64 contain a lot of redundant sources. I would like to
merge them into a new single directory, let say 'vdso', and use the
files in that directory to build both vdso32.so and vdso64.so. I have a
feeling that x86 is doing it that way, but I've not been able to figure
out how to build two objects using the same C/S files.
Thanks
Christophe
