Implement asm_mmu_enable and flush_tlb_all, and then make a final
change to mmu.c in order to link it into arm64. The final change
is to map the code read-only. This is necessary because armv8
forces all writable code shared between EL1 and EL0 to be PXN.

When $ARCH != $TEST_DIR we should look there too. This patch cheats
though and makes cscope always look there, but then gets rid of the
duplicates generated when $ARCH == $TEST_DIR.

This first patch of this series fixes a bug caused by attempting
to use spinlocks without enabling the MMU. The next three do some

prep for the sixth, which finally turns the MMU on for arm unit

Well, virtio_bind will still need to be in lib/virtio.c, but just as
a wrapper to arch_virtio_bind.

Add report_xfail(), which is report(), but with another condition
allowing it to output PASS/FAIL/XPASS/XFAIL, rather than only
