From 67d7d66f27c49a87c6f28ccff814f5d7eaaccec6 Mon Sep 17 00:00:00 2001 From: David Gibson Date: Thu, 29 Mar 2018 18:29:38 +1100 Subject: target/ppc: Fold slb_nr into PPCHash64Options The env->slb_nr field gives the size of the SLB (Segment Lookaside Buffer). This is another static-after-initialization parameter of the specific version of the 64-bit hash MMU in the CPU. So, this patch folds the field into PPCHash64Options with the other hash MMU options. This is a bit more complicated that the things previously put in there, because slb_nr was foolishly included in the migration stream. So we need some of the usual dance to handle backwards compatible migration.
