I take that back. On today's next with patch 2 applied, I don't see a problem with no memory, so this does appear to have sorted the memory allocation failure. Sorry for misleading you & thanks!
With my patches for store_cpu_topology on RISC-V I do see it though, when called on the boot cpu. I must have mixed up which I had tested. I have a fix for that though & will update my patches later.
Thanks & apologies! Conor.
