This patch series adds the ability for a user-mode program to register
mmapped memory. The capability was developed to support the sharing of
device memory, for example PCI-E static/flash ram devices, on the network
with RDMA. It is also useful for sharing kernel resident data with distributed
system monitoring applications (e.g. vmstats) at zero overhead to the
monitored host.
