[PATCH v3 14/18] target/s390x: Rely on unwinding in s390_cpu_tlb_fill

2019-09-26 Thread Richard Henderson
We currently set ilen to AUTO, then overwrite that during unwinding, then overwrite that for the code access case. This can be simplified to setting ilen to our arbitrary value for the (undefined) code access case, then rely on unwinding to overwrite that with the correct value for the data access
