All VAX: Properly define Unimplemented Opcode specifier count mask
...
the opcode table first word consists of bits:
<7> = FPD is legal for this opcode.
<4:6> = number of specifiers for unimplemented opcodes (VAX subsets)
<3> = unused
<0:2> = number of specifiers
The mask used to be 0x70. The convention is that x_M_y is a mask value
<right-justified>, for a macro like:
#define get_foo(x) (((x) >> x_V_foo) & x_M_foo)
For a subset VAX (like the 3900), the unimplemented opcodes are those
that are recognized on a full VAX but simply trap as reserved instructions
(e.g., the H-floating instructions). This really only affected symbolic
printing and decoding of these instructions.

PDP11: Fixed spurious interrupt when setting GO
...
The code wasn't handling interrupts correctly when TCCM was written. In
particular, if the GO bit clears DONE, the code looked for the "SET IE" case
too soon and didn't clear the interrupt that was incorrectly generated.
The new code factors "GO" into the calculation.

VAX780: Fixed bad test for UBA intr level (COVERITY)
...
IPL_UBA already has the subtract built in:
So it shouldn't be extracted again.
The whole routine looks a little strange, but the way it works is
that an interrupt from the UBA itself sets <bit 31> in the returned vector.
Because the vector is read by code and not used by hardware, the flag
bit is "harmless."
UBA interrupts occur only under strange circumstances, like bad map
pages and device NXMs. Under the simulator, with a debugged OS, they
never happen.
