When flush_dcache_page is called, we needn't alaways flush the dcache.
Instead, we could set page->flag and flush them in update_mmu_cache().

From man gcc, -ffreestanding:

Assert that compilation targets a freestanding environment.
This implies -fno-builtin.  A freestanding environment is
one in which the standard library may not exist, and program
startup may not necessarily be at "main".  The most
obvious example is an OS kernel.  This is equivalent to
-fno-hosted.
