ARM: mm: use inner-shareable barriers for TLB and user cache operations
System-wide barriers aren't required for situations where we only need to make visibility and ordering guarantees in the inner-shareable domain (i.e. we are not dealing with devices or potentially incoherent CPUs). This patch changes the v7 TLB operations, coherent_user_range and dcache_clean_area functions to user inner-shareable barriers. For cache maintenance, only the store access type is required to ensure completion. Reviewed-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Will Deacon <will.deacon@arm.com>
