Changelog : v1 -> v2: v1: https://lore.kernel.org/linuxppc-dev/20210821092419.167454-1-sri...@linux.vnet.ibm.com/t/#u`` [ patch 1: Updated to use DIV_ROUND_UP instead of max to handle more situations ] [ patch 2: updated changelog to make it more generic powerpc issue ]
The 1st patch fixes a regression which causes a crash when booted with nr_cpus=2. The 2nd patch fixes a regression where lscpu on PowerVM reports more number of sockets that are available. The 3rd patch updates the fallback when L2-cache properties are not explicitly exposed to be the cpu_sibling_mask.
