+Branch: rmind-uvmplock
+Description: Reorganize locking in UVM for pmap(9)
+Status: Active
+Start Date: 15 March 2010
+End Date:
+Base Tag: rmind-uvmplock-base
+Maintainer: Mindaugas Rasiukevicius <[email protected]>
+Scope: Kernel
+Notes: Goals:
+
+ - Reorganize locking in UVM and serialize pmap(9) operations
+ on same page(s). New lock order: [vmpage-lock] -> pmap-lock.
+ Based on the patch from a...@.
+ - Simplify locking in pmap(9) modules by removing P->V locking.
+ - Use mutex_obj(9) on vmobjlock (and thus vnode_t::v_interlock)
+ to share locks among UVM objects where necessary.
+ - Optimize pmap_remove() with tracking in struct vm_map_entry.
+ - Unify /dev/mem et al in MI code and provide required locking.
