4c005fd35b Mostly undo rev. 1.287: for modified pages a table walk must be forced on 
the next write access to get the modified bit set in the PTE and that
won't happen if it hits the cache.

a22adee52d Default to not inlining __cpu_simple_lock(). 
- the locore version attempts to detect stuck locks

3097bbf440 pmap_extract4m: We can read a spurious invalid pte if the system is in 
the middle of the PTE update protocol. So, if at first we get an invalid
PTE, retry with the demap lock held.

ebfcdb612b Drop the special sun4d `tlb flush' lock. The pte update function already 
serialises access to the PTEs to reliably get ref/mod bits.

Rename pte4m_lock => demap_lock.

4f969ab39c pv_syncflags4m: no need to flush the cache. If the page is still mapped, 
its ref/mod status may change at any moment anyway. If a definitive status
is required the UVM code will unmap the page first.

83037215bf Do not maintain the number of valid pages per segment (`sg_npte') anymore
