Thanks!  BTW, it would be really nice to replace HWPMC_HOOKS in kern_linker.c with
EVENTHANDLER calls.  I think kld_load would just work (though you might need to
downgrade the lock before you run it).  For kld_unload it seems you want two events,
a kld_unload_try for your newly added event (since it can reject a kld_unload), and
perhaps kld_unload at the end where the current HWPMC_HOOK is.  Just an idea if
someone is looking for something to do.  I know there are other modules that need
to hook into linker events like this, and making HWPMC_HOOKS more generic would be
a big help.
