[PATCH 09/14] ARM: v6k: select generic atomic64 code according to V6 variants

From: Will Deacon <hidden>
Date: 2011-01-18 10:24:20

If CONFIG_CPU_V6 is enabled, avoid using the double-word exclusive
instructions in the kernel's atomic implementations as these are not
supported.  Fall back to the generic spinlock code instead.
