Modified Files: src/sys/arch/aarch64/aarch64: pmap.c src/sys/arch/aarch64/include: pmap.h Log Message: Part IV of ad's performance improvements for aarch64 - Implement pmap_growkernel(), and update kernel pmap's stats with atomics. - Then, pmap_kenter_pa() and pmap_kremove() no longer need to allocate memory nor take pm_lock, because they only modify L3 PTEs. - Then, pm_lock and pp_lock can be adaptive mutexes at IPL_NONE which are cheaper than spin mutexes. - Take the pmap's lock in pmap_extract() if not the kernel's pmap, otherwise pmap_extract() might see inconsistent state.
