Hi Guys,

I recall that several versions of 'genksyms' ago, Richard Henderson added a 'genksyms -p' flag to set a 'prefix string' for the generated symbols. The idea is that SMP builds can use 'genksyms -p smp_'.
This code is in modutils-2.1.55, modutils-2.1.71, and modutils-2.1.85, so I think it's safe for the 2.1.XX kernels to depend on it now.
It would be a short job for a Makefile hacker to go into Rules.make and patch the single rule that invokes GENKSYMS. In fact I think this is all the code that's needed:
# Rules.make ifdef SMP genksyms_smp_prefix := -p smp_ else genksyms_smp_prefix := endif
$(MODINCL)/%.ver: %.c $(CC) $(CFLAGS) -E -D__GENKSYMS__ $<\ | $(GENKSYMS) $(genksyms_smp_prefix) -k $(VERSION).$(PATCHLEVEL).$(SUBLEVEL) > $@.tmp mv $@.tmp $@
I don't have time to develop this idea but if someone wants to make a patch out of it, go for it.
