The root cause is the room 0x500..0xc00 is not enough when
KVM_HANDLER_PR expresses the real codes. The relationship is
KVM_HANDLER_PR depend on CONFIG_KVM_BOOK3S_PR depend on
CONFIG_KVM_BOOK3S_64_PR.
If possible, we can by pass it: just use CONFIG_KVM_BOOK3S_64_HV instead
of CONFIG_KVM_BOOK3S_64_PR (enter menuconfig -> Virtualization -> "KVM
support for POWER7 and PPC970 using hypervisor mode in host").
For 'allmodconfig', it will use CONFIG_KVM_BOOK3S_64_HV instead of
CONFIG_KVM_BOOK3S_64_PR, so 'allmodconfig' will not have this issue.
Next, I will continue to analyse how to fix it.
Welcome other members (especially the related maintainers) to provide
suggestions and completions.
Thanks.
