 Interrupts_State & Interrupts_Mask bits definition (Initial_Mask=800E)
 Machine check, PER and external interrupt subclass bit positions
 are fixed by the architecture and cannot be changed
 Floating interrupts are made pending to all CPUs, and are 
 recorded in the sysblk structure, CPU specific interrupts
 are recorded in the regs structure.

// Hercules internal bit# macro: bit numbers are referenced counting
// from the RIGHT to left (i.e. 31 <-- 0) and thus the numerical value
// of a set bit is equal to two raised to the power of the bit position.

// While this is the COMPLETE OPPOSITE from the way bit numbers are
// numbered in IBM architectural reference manuals, we do it this way
// anyway since that's the way Intel numbers their bits, thus allowing
// us to easily replace bit referencing statements with corresponding
// Intel assembler bit manipulation instructions (since Intel is still
// the predominant host architecture platform for Hercules)
