[PATCH] target/ppc/spapr: Update H_GET_CPU_CHARACTERISTICS bits

2021-05-03 Thread Nicholas Piggin
There are several new bits added to the hcall which reflect new issues found and new hardware mitigations. This adds the link stack flush behaviour, link stack flush accelerated instruction capability, and several L1D flush type behaviours (which are now being specified as negative in order to sim
