commit cad6f9a4c12dd4d5cdb2620e3fe24727ee81c7ce Author: Jan Beulich <jbeulich@xxxxxxxx> AuthorDate: Thu Dec 14 10:56:07 2023 +0100 Commit: Jan Beulich <jbeulich@xxxxxxxx> CommitDate: Thu Dec 14 10:56:07 2023 +0100 smp: move cpu_is_offline() definition It's all the same for the 3 arch-es which have it, and RISC-V would introduce a 4th instance. Put it in xen/smp.h instead, while still permitting asm/smp.h to define a custom variant if need be.
