mike.travis@hpe.com d7609f4210 x86/platform/UV: Add kernel parameter to set memory block size 
Add a kernel parameter that allows setting UV memory block size.  This
is to provide an adjustment for new forms of PMEM and other DIMM memory
that might require alignment restrictions other than scanning the global
address table for the required minimum alignment.  The value set will be
further adjusted by both the GAM range table scan as well as restrictions
imposed by set_memory_block_size_order().
