Greg Kroah-Hartman 0c335d55ce Revert "powerpc/numa: Fix percpu allocations to be NUMA aware" ... This reverts commit 8c92870bdb which is commit ba4a648f12f4cd0a8003dd229b6ca8a53348ee4b upstream. Michal Hocko writes: JFYI. We have encountered a regression after applying this patch on a large ppc machine. While the patch is the right thing to do it doesn't work well with the current vmalloc area size on ppc and large machines where NUMA nodes are very far from each other. Just for the reference the boot fails on such a machine with bunch of warning preceeding it. See http://lkml.kernel.org/r/20170724134240.GL25221@dhcp22.suse.cz It seems the right thing to do is to enlarge the vmalloc space on ppc but this is not the case in the upstream kernel yet AFAIK. It is also questionable whether that is a stable material but I will decision on you here. We have reverted this patch from our 4.4 based kernel. Newer kernels do not have enlarged vmalloc space yet AFAIK so they won't work properly eiter. This bug is quite rare though because you need a specific HW configuration to trigger the issue - namely NUMA nodes have to be far away from each other in the physical memory space.
