please turn this into CONFIG_ARCH_HAS_PTEP_MODIFY_PROT_TRANSACTION
instead.
The __HAVE_ARCH_ form is consistent with all the other conditional
things in asm/pgtable.h, like __HAVE_ARCH_PTEP_SET_ACCESS_FLAGS,
__HAVE_ARCH_PTEP_TEST_AND_CLEAR_YOUNG, etc. I don't think adding
CONFIG_ARCH_HAS_ for this one case is a good idea.
