From 2b5a9a37e97467fea67070a94529d6d07e549270 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 26 Mar 2018 16:59:15 +0200 Subject: 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.

Refactor these common defines to a common header file. The new common linux/compat_time.h is also useful as it will eventually be used to hold all the defines that are needed for compat time types that support non y2038 safe types. New architectures need not have to define these new types as they will only use new y2038 safe syscalls. This file can be deleted after y2038 when we stop supporting non y2038 safe syscalls.

To avoid adding completely new and untested code for this purpose, we introduce a new CONFIG_64BIT_TIME symbol. Every architecture that supports new 64 bit time_t syscalls enables this config. After this is done for all architectures, the CONFIG_64BIT_TIME symbol will be deleted.

Introduce COMPAT_32BIT_TIME to conditionally compile these functions. Note that turning off 32 bit time_t support requires more changes on architecture side. For instance, architecure syscall tables need to be updated to drop support for 32 bit time_t syscalls.
