[PATCH v9 06/15] s390x: Add SIDA memory ops

2020-03-11 Thread Janosch Frank
Protected guests save the instruction control blocks in the SIDA instead of QEMU/KVM directly accessing the guest's memory. Let's introduce new functions to access the SIDA. Also the new memops are available with KVM_CAP_S390_PROTECTED, so let's check for that. Signed-off-by: Janosch Frank
