Subject: [PATCH] MIPS: Fix HOTPLUG_PARALLEL dependency
Date: Mon, 27 Oct 2025 17:15:35 +0100 [thread overview]
Message-ID: <20251027-mips_paralell_hotplug-v1-1-82567f3e4b85@bootlin.com> (raw)
With MIPS, it is possible to have SMP enabled without HOTPLUG_CPU
selected. However, in kernel/cpu.c, some code that uses
HOTPLUG_PARALLEL also requires HOTPLUG_CPU to be selected. Therefore,
we should fix the HOTPLUG_PARALLEL dependency to depend on
HOTPLUG_CPU, not just SMP.
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202510270120.21wA1aX1-lkp@intel.com/
