Timothy McDaniel 7161ea01b1 event/dlb2: add inline functions
Add miscellaneous inline functions that may be called
from multiple files.  These functions include inline
assembly of new x86 instructions, such as movdir64b,
since they are not available as builtin functions in
the minimum supported GCC version.
