FWIW, I retested my sparc32 patches with PREEMPT=y and I don't see any issues. However, linux-next is a different story, where I don't get very far at all: BUG: Bad page state in process swapper pfn:005b4 If you're seeing this on powerpc too, I wonder if it's related to: https://lore.kernel.org/r/20200514170327.31389-1-r...@kernel.org since I think it just hit -next and the diffstat is all over the place. I've added Mike to CC just in case. Will
