dump: Add arch cleanup function
|
||||
|
||||
Some architectures (s390x) need to cleanup after a failed dump to be
|
||||
able to continue to run the vm. Add a cleanup function pointer and
|
||||
call it if it's set.

target/s390x/arch_dump: Add arch cleanup function for PV dumps
|
||||
|
||||
PV dumps block vcpu runs until dump end is reached. If there's an
|
||||
error between PV dump init and PV dump end the vm will never be able
|
||||
to run again. One example of such an error is insufficient disk space
|
||||
for the dump file.
|
||||
|
||||
Let's add a cleanup function that tries to do a dump end. The dump
|
||||
completion data is discarded but there's no point in writing it to a
|
||||
file anyway if there's a possibility that other PV dump data is
|
||||
missing.
