+ To support multiple TC microthreads acting as "CPUs" within
+ a VPE, VPE-wide interrupt mask bits must be specially manipulated
+ during interrupt handling. To support legacy drivers and interrupt
+ controller management code, SMTC has a "backstop" to track and
+ if necessary restore the interrupt mask. This has some performance
+ impact on interrupt service overhead. Disable it only if you know
+ what you are doing.
