I have been porting my patches over and hit a bit of a snag. It looked like my patches were not booting on the s390 - but not all the time. So I reverted back to mm-stable (059342d1dd4e) and found that also failed to boot sometimes on my qemu setup. When it fails it's ~4-5sec into booting. The last thing I see is: "[ 4.668916] Spectre V2 mitigation: execute trampolines" I've bisected back to commit e553f62f10d9 (mm, page_alloc: fix build_zonerefs_node()) With the this commit, I am unable to boot one out of three times. When using the previous commit I was not able to get it to hang after trying 10+ times. This is a qemu s390 install with KASAN on and I see no error messages. I think it's likely it is this patch, but no guaranteed.
