Subject: [PATCH 0/2] powerpc/64s: fix for CPU hotplug vs mm_cpumask bug
Date: Fri, 20 Nov 2020 12:57:55 +1000 [thread overview]
Message-ID: <20201120025757.325930-1-npiggin@gmail.com> (raw)
This fixes a race in powerpc mm_cpumask code, I hope the core kernel
patch looks okay and we could take it through the powerpc tree with
an ack from someone (Peter or Thomas, perhaps?)
Thanks,
Nick
