From 17435e5f8cf3ba8b3df1aa662f9921f0ccdd8a28 Mon Sep 17 00:00:00 2001 From: Deepa Dinamani Date: Tue, 13 Mar 2018 21:03:28 -0700 Subject: time: 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.
