 *	The value 0x88 means ASI_PRIMARY_LITTLE.
 *	The store or load to/from the address space will be done
 *	as little-endian. In the original xrog code, the value
 *	is defined as the macro ASI_PL.
 *
 *	In the original xorg code, "membar #StoreStore|#StoreLoad"
 *	is directly implemented as an instruction "0x8143e00a".
