Subject: [PATCH 0/3] powerpc/smp: Misc fixes
Date: Sat, 21 Aug 2021 14:54:16 +0530 [thread overview]
Message-ID: <20210821092419.167454-1-srikar@linux.vnet.ibm.com> (raw)
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 that are available.
The 3rd patch updates the fallback when L2-cache properties are not
explicitly exposed to be the cpu_sibling_mask.
