Hi, This is the next version of the patchset that adds required support in the KVM hypervisor to run secure guests on PEF-enabled POWER platforms. This version includes the following changes: - Ensure that any malicious calls to the 4 hcalls (init_start, init_done, page_in and page_out) are handled safely by returning appropriate errors (Paul Mackerras) - init_start hcall should work for only radix guests. - Fix the page-size-order argument in uv_page_inval (Ram Pai) - Don't free up partition scoped page tables in HV when guest becomes secure (Paul Mackerras) - During guest reset, when we unpin VPA pages, make sure that no vcpu is running and fail the SVM_OFF ioctl if any are running (Paul Mackerras) - Dropped the patch that implemented init_abort hcall as it still has unresolved questions.
