Only when vma is for VM_EXEC, we need sync dcache & icache. eg: - gdb ptrace modify user space instruction code area. Add VM_EXEC condition to reduce unnecessary cache flush. The abiv1 cpus' cache are all VIPT, so we still need to deal with dcache aliasing problem. But there is optimized way to use cache color, just like what's done in arch/csky/abiv1/inc/abi/page.h.
