I think this is really a general problem of lkm vs kernel options and
not about xen, except that xen kenrels have DEBUG/DIAGNOSTIC set.
I added
CPPFLAGS+= -DDIAGNOSTIC
to /usr/src/sys/lkm/Makefile.inc
and then build.sh builds lkms with DIAGNOSTIC. Of course, they then
don't work with non-DIAGNOSTIC kernels.
I think what is needed is either
1) treat lkms needing a flag as a bug and fix them. This is probably
too hard.
2) Enumerate the n flags that matter in some config file, and build
2^n flavors of lkms with build.sh, or perhaps just have a way to
configure the requested sets.
3) Stop using lkms.
