x86/paravirt: Fix callee-saved function ELF sizes
The __raw_callee_save_*() functions have an ELF symbol size of zero, which confuses objtool and other tools. Fixes a bunch of warnings like the following: arch/x86/xen/mmu_pv.o: warning: objtool: __raw_callee_save_xen_pte_val() is missing an ELF size annotation arch/x86/xen/mmu_pv.o: warning: objtool: __raw_callee_save_xen_pgd_val() is missing an ELF size annotation arch/x86/xen/mmu_pv.o: warning: objtool: __raw_callee_save_xen_make_pte() is missing an ELF size annotation arch/x86/xen/mmu_pv.o: warning: objtool: __raw_callee_save_xen_make_pgd() is missing an ELF size annotation Signed-off-by: Josh Poimboeuf <jpoimboe@redhat.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Reviewed-by: Juergen Gross <jgross@suse.com> Acked-by: Peter Zijlstra (Intel) <peterz@infradead.org> Link: https://lkml.kernel.org/r/afa6d49bb07497ca62e4fc3b27a2d0cece545b4e.1563413318.git.jpoimboe@redhat.com
