Commit-ID: 2b5a9a37e97467fea67070a94529d6d07e549270 Gitweb: https://git.kernel.org/tip/2b5a9a37e97467fea67070a94529d6d07e549270 Author: Arnd Bergmann <arnd@xxxxxxxx> AuthorDate: Mon, 26 Mar 2018 16:59:15 +0200 Committer: Arnd Bergmann <arnd@xxxxxxxx> CommitDate: Thu, 19 Apr 2018 13:28:51 +0200 time: Add an asm-generic/compat.h file We have a couple of files that try to include asm/compat.h on architectures where this is available. Those should generally use the higher-level linux/compat.h file, but that in turn fails to include asm/compat.h when CONFIG_COMPAT is disabled, unless we can provide that header on all architectures. This adds the asm/compat.h for all remaining architectures to simplify the dependencies. Architectures that are getting removed in linux-4.17 are not changed here, to avoid needless conflicts with the removal patches. Those architectures are broken by this patch, but we have already shown that they have no users.
