Include opt_multiprocessor.h
When allocing a l1page, if a page isn't available, use uvm_wait to wait
for one to become available.  Should fix PR/49364.
Post a dmb before invalidating the cache in the post-{read,write}
operations to ensure that any/all cachelines brought in via speculation
are really flushed.
Ensure all memory operations are complete by before wfi. For example, the
cpu could have just been in uvm_pageidlezero.
In pmap_fault_fixup re-instate the TLB flush for the shared L1 case that
occurs for non-ARM_MMU_EXTENDED kernels.
This fixes rump/rumpkern/t_sp:stress_killer on rpi which is currently
non-ARM_MMU_EXTENDED
Remove an unnecessary flush that sneaked in as part of break-before-make
change.
Remove an XXXNH comment.
Update PTE_SYNC_CURRENT to add a dsb for armv7 - part of the
break-before-make fix.
