Subject: s390x/s390-virtio-ccw: Fix build on systems without KVM
|
|
|
|
References: bsc#1167075
|
|
|
|
linux/kvm.h is not available on all platforms. Let us move
|
|
s390_machine_inject_pv_error into pv.c as it uses KVM structures.
|
|
Also rename the function to s390_pv_inject_reset_error.
|
|
|
|
While at it, ipl.h needs an include for "exec/address-spaces.h"
|
|
as it uses address_space_memory.
|
|
|
|
Fixes: 49fc3220175e ("s390x: protvirt: Support unpack facility")
