Er, this doesn't compile:

../../target/arm/cpu.c:2223:19: error: no member named 'id_mfr2' in
'struct ARMISARegisters'
        cpu->isar.id_mfr2 = t;
        ~~~~~~~~~ ^

The typo is obvious, so I'm just going to fix it up in the
target-arm queue, but this does suggest that your testing process
before sending out patches could be improved ;-)
