Subject[PATCH 5/6] i386 virtualization - Make generic set wrprotect a macro
Make the generic version of ptep_set_wrprotect a macro.  This is good for
code uniformity, and fixes the build for architectures which include pgtable.h
through headers into assembly code, but do not define a ptep_set_wrprotect
function.
