From: Rafael J. Wysocki Date: Wed, 13 Aug 2025 10:36:04 +0000 (+0200) Subject: ACPI: processor: idle: Add module import namespace X-Git-Tag: v6.18-rc1~151^2~3^3~8 X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=eb58738d1546bababc77392968ece9c595b4f737;p=thirdparty%2Flinux.git ACPI: processor: idle: Add module import namespace Add a new module import namespace called ACPI_PROCESSOR_IDLE for functions exported from the non-modular part of the ACPI processor driver to the modular part of it. Export acpi_processor_claim_cst_control() and acpi_processor_evaluate_cst() in that namespace to hide them from unrelated modules. They are also used by the intel_idle driver, but it is non-modular, so it can call them regardless of the way the symbols are exported. Signed-off-by: Rafael J.
