[PATCH 07/14] ARM: v6k: select clear exclusive code seqences according to V6 variants

[Tony Lindgren]

* Russell King - ARM Linux <linux at arm.linux.org.uk> [110117 11:27]:
> If CONFIG_CPU_V6 is enabled, then the kernel must support ARMv6 CPUs
> which don't have the V6K extensions implemented.  Always use the
> dummy store-exclusive method to ensure that the exclusive monitors are
> cleared.
> 
> If CONFIG_CPU_V6 is not set, but CONFIG_CPU_32v6K is enabled, then we
> have the K extensions available on all CPUs we're building support for,
> so we can use the new clear-exclusive instruction.
