RH-Commit: [13/91] e25c498fc79a4c8e22ca41d9cbd06e40b4cf1f11 (bonzini/rhel-qemu-kvm)
|
||
|
|
|
||
|
|
Use the unified interface to call confidential guest related kvm_init()
|
||
|
|
and kvm_reset(), to avoid exposing pef specific functions.
|
||
|
|
|
||
|
|
As a bonus, pef.h goes away since there is no direct call from sPAPR
|
||
|
|
board code to PEF code anymore.
