x86/paravirt: Fix callee-saved function ELF sizes
[ Upstream commit 083db6764821996526970e42d09c1ab2f4155dd4 ]
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
