The new and improved type checking makes it very hard for stuff like errno_to_smccc(), which seems to be designed to avoid any form of C type checking. Things like __pkvm_init_vm() would need to return a struct by value, I expect. Please rebase on top of Fuad's stuff... Thanks, M. -- Without deviation from the norm, progress is not possible.
