stack: grow on page fault
...
The steps of the technique to replace stack with hugetlbfs map are as
follows:
(1) Prepare a hugetlbfs map with the size of rlim_cur
(2) Copy the active region of the stack to the hugetlbfs map.
The range to copy is determined by reading /proc/[pid]/maps.
(3) Replace the stack map with the hugetlbfs map
The step (2) tries to copy a huge region if McKernel doesn't grow the
stack at run-time.

xpmem: fix mapping of attachment and segment
...
* Mapping attached part of segment is done at attach time instead of
make time to work with runtimes (e.g. OpenMPI) xpmem_make-ing the
entire user-space
* Mapping attached part of segment at attach time can be turned off by
specifying xpmem_remote_on_demand in kernel argument
* Mapping attachment chooses appropriate page-sizes, i.e., largest
allowed by memory range and segment page boundary
