("MIPS: Add support for XPA.") added generation of a shift by _PAGE_PRESENT_SHIFT in build_pte_present() and build_pte_writable(), however except for the XPA case this is always zero making it unnecessary. Make the shift conditional upon _PAGE_PRESENT_SHIFT being non-zero to save an instruction in those cases. Fixes:c5b367835c
