From da92df490eeab7a97a3390ff32e0ae091e0dc2eb Mon Sep 17 00:00:00 2001 From: Alexey Dobriyan Date: Mon, 5 Feb 2024 13:01:19 +0300 Subject: cpu: Mark cpu_possible_mask as __ro_after_init cpu_possible_mask is by definition "cpus which could be hotplugged without reboot". It's a property which is fixed after kernel enumerates the hardware configuration.
