kvm: selftests: dirty_log_test: always use -t
There's no reason not to always test the topmost physical addresses, and if the user wants to try lower addresses then '-p' (used to be '-o before this patch) can be used. Let's remove the '-t' option and just always do what it did. Signed-off-by: Andrew Jones <drjones@redhat.com> Signed-off-by: Radim Krčmář <rkrcmar@redhat.com>
