On s390 the disabled wait state indicates a state of attention.
For example Linux uses that state after a panic. Lets
put the system into panicked state.

An alternative implementation would be to state
disabled-wait <address> instead of pause in the action field.
(e.g. z/OS, z/VM and other classic OSes use the address of the
disabled wait to indicate an error code).

pvpanic device is used to send guest panic event from guest to qemu.

When guest panic happens, pvpanic device driver will write a event
number to IO port 0x505(which is the IO port occupied by pvpanic device,
by default). On receiving the event, pvpanic device will pause guest
cpu(s), and send a qmp event QEVENT_GUEST_PANICKED.

The following error occurs when building dtc module:

        CHK version_gen.h
         CC libfdt/fdt.o
cc1: error: dtc: No such file or directory [-Werror]
cc1: all warnings being treated as errors
make[1]: *** [libfdt/fdt.o] Error 1
make: *** [subdir-dtc] Error 2

In rules.mak, "-I$(<D) -I$(@D)" was expanded to "-Idtc -I." when
building submodule dct. Due to the using of "-Wmissing-include-dirs,
a warning would be rarsed. To avoid it, add "-I$(<D) -I$(@D)" to
QEMU_INCLUDES instead of QEMU_CFLAGS so that QEMU_CFLAGS does not
contain the "-Idtc".
