I haven't studied ARMv6, but I can say that at least some assembly
instructions used by the cache maintenance code in kern/arm/cache.S
(such as DMB, DSB and ISB) have been introduced in ARMv7, as well as
some coprocessor operations (specifically, I'm looking at those used in
the clean_invalidate_dcache routine in the same file).
