The trap number for a page fault on BSD systems is T_PAGEFLT not 0xe -- 0xe is used by Linux and represents the intel hardware trap vector. The BSD kernels, however, translate this to T_PAGEFLT in their Xpage, Xtrap0e, Xtrap14, etc fault handlers. This is true for i386 and x86_64, though the name of the trap hanlder can very on the flavor of BSD. As far as I can tell, Linux doesn't provide a define for this value. Invent a new one (PAGE_FAULT_TRAP) and use it instead to avoid uglier ifdefs.
