[PATCH v2 0/3] powerpc/smp: Misc fixes

[Srikar Dronamraju <srikar@linux.vnet.ibm.com>]

Changelog : v1 -> v2:
v1: https://lore.kernel.org/linuxppc-dev/20210821092419.167454-1-srikar@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.
