x86/paravirt: Fix callee-saved function ELF sizes

Browse source

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
