Log message:
fix mask in hppa inst_trap_return()
inst_trap_return() was checking for rfir by masking with 0xfc001fc0
which made it impossible to match rfir (0xca0)
rfi: return from interruption
00 rv rv rv 60 0
6 5 5 3 8 5
rfir: return from interruption and restore
00 rv rv rv 65 0
6 5 5 3 8 5
from "PA-RISC 1.1 Architecture and Instruction Set Reference Manual"
where rv indicates reserved bits
change the mask to only mask out reserved bits and check for rfi
in addition to rfir
