## Description

In the Linux kernel, the following vulnerability has been resolved:  powerpc/rtas: Prevent Spectre v1 gadget construction in sys_rtas()  Smatch warns:    arch/powerpc/kernel/rtas.c:1932 __do_sys_rtas() warn: potential   spectre issue 'args.args' [r] (local cap)  The 'nargs' and 'nret' locals come directly from a user-supplied buffer and are used as indexes into a small stack-based array and as inputs to copy_to_user() after they are subject to bounds checks.  Use array_index_nospec() after the bounds checks to clamp these values for speculative execution.
