Ingo Molnar 1ac91a767f x86/fpu: Simplify fpstate_sanitize_xstate() calls ... Remove the extra layer of __fpstate_sanitize_xstate(): if (!use_xsaveopt()) return; __fpstate_sanitize_xstate(tsk); and move the check for use_xsaveopt() into fpstate_sanitize_xstate(). In general we optimize for the presence of CPU features, not for the absence of them. Furthermore there's little point in this inlining, as the call sites are not super hot code paths. Doing this uninlining shrinks the code a bit: text data bss dec hex filename 14108751 2573624 1634304 18316679 1177d87 vmlinux.before 14108627 2573624 1634304 18316555 1177d0b vmlinux.after Also remove a pointless '!fx' check from fpstate_sanitize_xstate().
