Zi Yan 5c0541e11c mm: introduce cpu_icache_is_aliasing() across all architectures 
In commit eacd0e950d ("ARC: [mm] Lazy D-cache flush (non aliasing
VIPT)"), arc adds the need to flush dcache to make icache see the code
page change.  This also requires special handling for
clear_user_(high)page().  Introduce cpu_icache_is_aliasing() to make MM
code query special clear_user_(high)page() easier.  This will be used by
the following commit.
