Marc Zyngier fdc9999e20 KVM: arm64: PSCI: Forbid 64bit functions for 32bit guests ... Implementing (and even advertising) 64bit PSCI functions to 32bit guests is at least a bit odd, if not altogether violating the spec which says ("5.2.1 Register usage in arguments and return values"): "Adherence to the SMC Calling Conventions implies that any AArch32 caller of an SMC64 function will get a return code of 0xFFFFFFFF(int32). This matches the NOT_SUPPORTED error code used in PSCI" Tighten the implementation by pretending these functions are not there for 32bit guests.
