  Message : Change kcopy(9) such that it does 64-bit and 32-bit copies whenever possible. This makes sure a kcopy(9) that is a sequence of 64-bit or 32-bit values that are properly aligned is done atomically. This is needed for kbind(2) as it needs to update PLT/GOT entries atomically when doing lazy binding. This seems to fix some random SIGSEGV and SIGTRAP when linking stuff with ld.lld. ok deraadt@, patrick@, drahn@
