It looks like they leave interrupts disabled when they shouldn't and it trips over the BUG at mm/vmalloc.c:1380 (called via do_fork -> copy_process). Now, I don't think these patches make things worse on arm64 since prior to them the kgdb boot tests on arm64 were stuck in a loop (RUN singlestep). -- Catalin _______________________________________________ linux-snps-arc mailing list linux-snps-arc@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/linux-snps-arc
