This series applies on top of the multi-migration patches and just
has assorted things I've been collecting.

- New migrate_skip() command that tidies up the wart of using
migrate_once() to skip migration.
- New "continuous migration" mode where the harness just
migrates the test contually while it is running.
- Put some migration tests in gitlab CI for powerpc and s390.
- Add a test case that can reproduce the QEMU TCG dirty bitmap
migration bug.

Nicholas Piggin (7):
arch-run: Keep infifo open
migration: Add a migrate_skip command
(arm|s390): Use migrate_skip in test cases
powerpc: add asm/time.h header with delay and get_clock_us/ms
arch-run: Add a "continuous" migration option for tests
gitlab-ci: Run migration selftest on s390x and powerpc
common: add memory dirtying vs migration test
