A CAN sja1000 standard frame filter mask has been computed and applied
incorrectly for standard frames when single Acceptance Filter Mode
(MOD_AFM = 1) has been selected. The problem has not been found
by Linux kernel testing because it uses dual filter mode (MOD_AFM = 0)
and leaves falters fully open.
The problem has been noticed by Grant Ramsay when testing with Zephyr
RTOS which uses single filter mode.

It's no sense to check the CPU type when mc->valid_cpu_types[0] is
NULL, which is a program error. Raise an assert on this.
A precise hint for the error message is given when mc->valid_cpu_types[0]
is the only valid entry. Besides, enumeration on mc->valid_cpu_types[0]
when we have mutiple valid entries there is avoided to increase the code
readability, as suggested by Philippe Mathieu-Daudé.
Besides, @cc comes from machine->cpu_type or mc->default_cpu_type. For
the later case, it can be NULL and it's also a program error. We should
use assert() in this case.

The logic, to check if the specified CPU type is supported in
machine_run_board_init(), is independent enough. Factor it out into
helper is_cpu_type_supported(). machine_run_board_init() looks a bit

Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org>
Functions that use an Error **errp parameter to return errors should
not also report them to the user, because reporting is the caller's
job. The principle is violated by machine_run_board_init() because
it calls error_report(), error_printf(), and exit(1) when the machine
doesn't support the requested CPU type.
Clean this up by using error_setg() and error_append_hint() instead.
No functional change, as the only caller passes &error_fatal.

When a vm transitions from running to suspended, runstate notifiers are
not called, so the notifiers still think the vm is running. Hence, when
we call vm_start to restore the suspended state, we call vm_state_notify
with running=1. However, some notifiers check for RUN_STATE_RUNNING.
They must check the running boolean instead.
