From: Rafael J. Wysocki Date: Thu, 21 Sep 2023 12:58:02 +0000 (+0200) Subject: ACPI: processor: Provide empty stub of acpi_proc_quirk_mwait_check() X-Git-Tag: microblaze-v6.10~663^2~6^3~2 X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=4c2ba6a0ed1944c17b957157bd1e686be4ea968a;p=linux-2.6-microblaze.git ACPI: processor: Provide empty stub of acpi_proc_quirk_mwait_check() Commit 0a0e2ea642f6 ("ACPI: processor: Move MWAIT quirk out of acpi_processor.c") added acpi_proc_quirk_mwait_check() that is only defined for x86 and is unlikely to be defined for any other architectures, so put it under #ifdef CONFIG_X86 and provide an empty stub implementation of it for the other cases. This is kind of orthogonal to [1], because if any architectures other than x86 decide to use the processor _OSC, they will see the reported build error.
