uti: futex call function in mcctrl
...
Previously, futex code of McKerenl was called by mccontrol,
but there ware some problems with this method.
(Mainly, location of McKernel image on memory)
Call futex code in mcctrl instead of the one in McKernel image,
giving the following benefits:
1. Not relying on shared kernel virtual address space with Linux any more
2. The cpu id store / retrieve is not needed and resulting in the code

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
