Wait for RAM in uvm_fault when allocating uvm structures fails
Only fail hard when running out of swap space also, as suggested by
kettenis@
While there, let amap_add() return a success status and handle
amap_add() errors in uvm_fault() similar to other out of RAM situations.
These bits are needed for further amap reorganization diffs.
lots of feedback and ok kettenis@
