Well for example this might get in the way of building kernel for HSDK with CONFIG_SMP disabled which is IMHO quite valid case in terms of testing code-base compiled with no CONFIG_SMP (something Waldemar was up to). Is it a strong enough reason for that patch to be applied? -Alexey _______________________________________________ linux-snps-arc mailing list linux-snps-arc@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-snps-arc
