sparc64: Add 16GB hugepage support
Adds support for 16GB hugepage size. To use this page size
use kernel parameters as:
default_hugepagesz=16G hugepagesz=16G hugepages=10
Testing:
Tested with the stream benchmark which allocates 48G of
arrays backed by 16G hugepages and does RW operation on
them in parallel.
