Log message:
Also insert two nop instructions after svc instructions for SYS_exit
and SYS_sigreturn in the sigtramp. As these control-flow into a jump
or process termination, we never do the +8 dance over the
instructions, however the speculation prevention (once these nops are
replaced with a speculation barrier) is required.
oversight noticed by Anthony Steinhauser.
