Subject: xen/cpu: Fix ARM build following c/s 597fbb8
From: Andrew Cooper andrew.cooper3@citrix.com Mon Apr 8 18:20:07 2019 +0100
Date: Tue Apr 9 10:12:57 2019 +0100:
Git: a6448adfd3d537aacbbd784e5bf1777ab3ff5f85
c/s 597fbb8 "xen/timers: Fix memory leak with cpu unplug/plug" broke the ARM
build by being the first patch to add park_offline_cpus to common code.
While it is currently specific to Intel hardware (for reasons of being able to
handle machine check exceptions without an immediate system reset), it isn't
inherently architecture specific, so define it to be false on ARM for now.
Add a comment in both smp.h headers explaining the intended behaviour of the
option.
