Message-Id: <20180116021818.24791-6-deepa.kernel@gmail.com> Date: Mon, 15 Jan 2018 18:18:13 -0800 From: Deepa Dinamani <deepa.kernel@...il.com> To: tglx@...utronix.de, john.stultz@...aro.org Cc: linux-kernel@...r.kernel.org, arnd@...db.de, y2038@...ts.linaro.org Subject: [PATCH v3 05/10] arch: Introduce CONFIG_COMPAT_32BIT_TIME Compat functions are now used to support 32 bit time_t in compat mode on 64 bit architectures and in native mode on 32 bit architectures. 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.
