Module Name:    src

        src/sys/uvm: uvm_km.c uvm_map.c uvm_page.c

Log Message:
It's easier for kernel reserve pages to be consumed because the pagedaemon
serves as less of a barrier these days. Restrict provision of kernel reserve
pages to kmem and one of these cases:

- doing a NOWAIT allocation
- caller is a realtime thread
- caller is a kernel thread
- explicitly requested, for example by the pmap
