This is a note to let you know that I've just added the patch titled init/Kconfig: make COMPILE_TEST depend on !S390 to the 4.9-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: init-kconfig-make-compile_test-depend-on-s390.patch and it can be found in the queue-4.9 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From 334ef6ed06fa1a54e35296b77b693bcf6d63ee9e Mon Sep 17 00:00:00 2001 From: Heiko Carstens <hca@xxxxxxxxxxxxx> Date: Wed, 18 Nov 2020 21:32:33 +0100 Subject: init/Kconfig: make COMPILE_TEST depend on !S390 From: Heiko Carstens <hca@xxxxxxxxxxxxx> commit 334ef6ed06fa1a54e35296b77b693bcf6d63ee9e upstream. While allmodconfig and allyesconfig build for s390 there are also various bots running compile tests with randconfig, where PCI is disabled. This reveals that a lot of drivers should actually depend on HAS_IOMEM. Adding this to each device driver would be a never ending story, therefore just disable COMPILE_TEST for s390. The reasoning is more or less the same as described in commit bc083a64b6c0 ("init/Kconfig: make COMPILE_TEST depend on !UML").
