linux/kvm.h is not available on all platforms. Let us move
|
|
|
ddf19c |
s390_machine_inject_pv_error into pv.c as it uses KVM structures.
|
|
|
ddf19c |
Also rename the function to s390_pv_inject_reset_error.
|
|
|
ddf19c |
|
|
|
ddf19c |
While at it, ipl.h needs an include for "exec/address-spaces.h"
|
|
|
ddf19c |
as it uses address_space_memory.
|
|
|
