Message-Id: <1430929826-318934-4-git-send-email-arnd@arndb.de>
Date: Wed, 6 May 2015 18:30:10 +0200
From: Arnd Bergmann <arnd@...db.de>
To: y2038@...ts.linaro.org
Cc: baolin.wang@...aro.org, tglx@...utronix.de,

Subject: [PATCH 03/19] y2038: introduce linux/compat_time.h header
We want to reuse all the compat syscall handling for native syscalls
on 32-bit architectures when dealing with 32-bit time_t types.
This moves all time-related system call declarations from
include/linux/compat.h to include/linux/compat_time.h, along
with the associated data structures and typedefs.
Signed-off-by: Arnd Bergmann <arnd@...db.de>
