The flush_dcache_page() function is called when the kernel modified a page cache page. Since the D-cache on AArch64 does not have aliases this function can simply mark the page as dirty for later flushing via set_pte_at()/__sync_icache_dcache() if the page is executable (to ensure the I-D cache coherency).
