MFC 228509,228620,228533:
Add a helper API to allow in-kernel code to map portions of shared memory
objects created by shm_open(2) into the kernel's address space.  This
provides a convenient way for creating shared memory buffers between
userland and the kernel without requiring custom character devices.
