* Russell King - ARM Linux <linux at arm.linux.org.uk> [110117 11:24]:
> CPU_32v6K controls whether we use the ARMv6K extension instructions in
> the kernel, and in some places whether we use SMP-safe code sequences
> (eg, bitops.)
> 
> MX3 prevents the selection of this option to ensure that it is not
> enabled for their CPU, which is ARMv6 only.  Now that we've split the
> CPU_V6 option, V6K support won't be offered for MX3 anymore.
> 
> OMAP prevents the selection of this option in an attempt to produce a
> kernel which runs on architectures from ARMv6 to ARMv7 MPCore.  We now
> achieve this in a different way (see the previous patches).
> 
> As such, we no longer need to offer this as a configuration option to
> the user.
