Since omap_mmc is still using the legacy SD card API, the SD card created by sd_init() is not plugged into any bus. This means that the controller has to reset it manually. Failing to do this mostly didn't affect the guest since the guest typically does a programmed SD card reset as part of its SD controller driver initialization, but would mean that migration fails because it's only in sd_reset() that we set up the wpgrps_size field.

For PMSAv7, the v7A/R Arm ARM defines that setting AP to 0b111 is an UNPREDICTABLE reserved combination. However, for v7M this value is documented as having the same behaviour as 0b110: read-only for both privileged and unprivileged. Accept this value on an M profile core rather than treating it as a guest error and a no-access page.

Firstly, it was passed around. Let's just move it into MigrationState just like many other variables as state of migration, renaming it to vm_was_running. One thing to mention is that for postcopy, we actually don't need this knowledge at all since postcopy can't resume a VM even if it fails (we can see that from the old code too: when we try to resume we also check against "entered_postcopy" variable). So further we do this: - in postcopy_start(), we don't update vm_old_running since useless - in migration_thread(), we don't need to check entered_postcopy when resume, since it's only used for precopy. Comment this out too for that variable definition. Reviewed-by: NJuan Quintela <quintela@redhat.com> Signed-off-by: NPeter Xu <peterx@redhat.com> Signed-off-by: NJuan Quintela <quintela@redhat.com>
