To use bit 5 in page table as L_PTE_SPECIAL, we need a room for that.
It seems we don't need 4 bits for the memory type with ARMv6+.
If it's true, let's reorder bits to make bit 5 free.
We will use the bit for L_PTE_SPECIAL in next patch.

Recently, there was a report get_user_pages_fast helps app launching
speed due to reducing uninterruptible sleep time because we don't

With get_user_pages_fast, that uniterruptible sleep time is reduced
about 5~10% by testing.
