The arm and arm64 VDSOs need CP15 access to the architected counter.
If this is unavailable (which is allowed by ARM v7), indicate this by
changing the clocksource name to "arch_mem_counter" before registering
the clocksource.

Hi Nathan,

is it possible to have the acked-by of the different maintainers for the
other patches ?

FWIW: I acked the series:

http://lists.infradead.org/pipermail/linux-arm-kernel/2014-September/289143.html

There's ongoing debate about whether or not we should have a vdso, but this
series still makes sense in isolation.

Ok. Thanks for the clarification.
