[PATCH 07/10] staging: lustre: Handle nodemask on UMP machines

[James Simmons]

For UMP and SMP machines the struct cfs_cpt_table are
defined differently. In the case handled by this patch
nodemask is defined as a integer for the UMP case and
as a pointer for the SMP case. This will cause a problem
for ost_setup which reads the nodemask directly. Instead
we create a UMP version of cfs_cpt_nodemask and use that
in ost_setup.
