kernel: powerpc/pseries: Enforce hcall result buffer validity and size

A vulnerability was found in the Linux kernel's powerpc/pseries architecture, where certain hypercall functions did not properly enforce the validity and size of result buffers provided by callers, lead to stack corruption if the buffer is too small, as the lack of compiler checks allows for...
