Date: Tue, 13 May 2014 16:57:36 +0800 From: Ley Foon Tan <lftan@...era.com> To: <linux-arch@...r.kernel.org>, <linux-kernel@...r.kernel.org> CC: Ley Foon Tan <lftan@...era.com>, <lftan.linux@...il.com>, <cltang@...esourcery.com>, Arnd Bergmann <arnd@...db.de> Subject: [PATCH 00/25] Change time_t and clock_t to 64 bit This patchset change default time_t and clock_t to 64 bit in include/uapi/asm-generic/posix_types.h. The existing 32 bit architectures override these define to 32 bit in arch posix_types.h. There is request to support 64 bit time_t for new architecture [1]. According to the previous discussion we had (in [2]), defining suseconds_t as 64-bit, while probably reasonable for LP64 or LP64+ILP32 architectures, but can makes things troublesome for ILP32 architectures, not to mention the additional overhead. This series is compiled tested on ARM, mips, powerpc32 and x86_64, but only boot tested on ARM. These patches are also available on this branch: git://git.rocketboards.org/linux-socfpga-next.git 64bit_time [1] https://lkml.org/lkml/2012/11/14/358 [2] https://lkml.org/lkml/2014/4/18/216 Ley Foon Tan (25): asm-generic: Change time_t and clock_t to 64 bit arc: Add 32 bit time_t and clock_t arm: Add 32 bit time_t and clock_t avr32: Add 32 bit time_t and clock_t blackfin: Add 32 bit time_t and clock_t c6x: Add 32 bit time_t and clock_t cris: Add 32 bit time_t and clock_t frv: Add 32 bit time_t and clock_t hexagon: Add 32 bit time_t and clock_t m32r: Add 32 bit time_t and clock_t m68k: Add 32 bit time_t and clock_t metag: Add 32 bit time_t and clock_t microblaze: Add 32 bit time_t and clock_t mips: Add 32 bit time_t and clock_t mn10300: Add 32 bit time_t and clock_t openrisc: Add 32 bit time_t and clock_t parisc: Add 32 bit time_t and clock_t powerpc: Add 32 bit time_t and clock_t s390: Add 32 bit time_t and clock_t score: Add 32 bit time_t and clock_t sh: Add 32 bit time_t and clock_t sparc: Add 32 bit time_t and clock_t unicore32: Add 32 bit time_t and clock_t x86: Add 32 bit time_t and clock_t xtense: Add 32 bit time_t and clock_t arch/arc/include/asm/Kbuild | 1 - arch/arc/include/uapi/asm/Kbuild | 1 + arch/arc/include/uapi/asm/posix_types.h | 17 +++++++++++++++++ arch/arm/include/uapi/asm/posix_types.h | 6 ++++++ arch/avr32/include/uapi/asm/posix_types.h | 6 ++++++ arch/blackfin/include/uapi/asm/posix_types.h | 6 ++++++ arch/c6x/include/asm/Kbuild | 1 - arch/c6x/include/uapi/asm/Kbuild | 1 + arch/c6x/include/uapi/asm/posix_types.h | 17 +++++++++++++++++ arch/cris/include/uapi/asm/posix_types.h | 6 ++++++ arch/frv/include/uapi/asm/posix_types.h | 6 ++++++ arch/hexagon/include/asm/Kbuild | 1 - arch/hexagon/include/uapi/asm/Kbuild | 1 + arch/hexagon/include/uapi/asm/posix_types.h | 17 +++++++++++++++++ arch/m32r/include/uapi/asm/posix_types.h | 6 ++++++ arch/m68k/include/uapi/asm/posix_types.h | 6 ++++++ arch/metag/include/asm/Kbuild | 1 - arch/metag/include/uapi/asm/Kbuild | 1 + arch/metag/include/uapi/asm/posix_types.h | 17 +++++++++++++++++ arch/microblaze/include/uapi/asm/posix_types.h | 6 ++++++ arch/mips/include/uapi/asm/posix_types.h | 6 ++++++ arch/mn10300/include/uapi/asm/posix_types.h | 6 ++++++ arch/openrisc/include/asm/Kbuild | 1 - arch/openrisc/include/uapi/asm/Kbuild | 1 + arch/openrisc/include/uapi/asm/posix_types.h | 17 +++++++++++++++++ arch/parisc/include/uapi/asm/posix_types.h | 8 ++++++++ arch/powerpc/include/uapi/asm/posix_types.h | 6 ++++++ arch/s390/include/uapi/asm/posix_types.h | 6 ++++++ arch/score/include/uapi/asm/posix_types.h | 6 ++++++ arch/sh/include/uapi/asm/posix_types_32.h | 6 ++++++ arch/sparc/include/uapi/asm/posix_types.h | 6 ++++++ arch/unicore32/include/asm/Kbuild | 1 - arch/unicore32/include/uapi/asm/Kbuild | 1 + arch/unicore32/include/uapi/asm/posix_types.h | 17 +++++++++++++++++ arch/x86/include/uapi/asm/posix_types_32.h | 6 ++++++ arch/xtensa/include/uapi/asm/posix_types.h | 6 ++++++ include/uapi/asm-generic/posix_types.h | 14 ++++++++++++-- 37 files changed, 230 insertions(+), 8 deletions(-) create mode 100644 arch/arc/include/uapi/asm/posix_types.h create mode 100644 arch/c6x/include/uapi/asm/posix_types.h create mode 100644 arch/hexagon/include/uapi/asm/posix_types.h create mode 100644 arch/metag/include/uapi/asm/posix_types.h create mode 100644 arch/openrisc/include/uapi/asm/posix_types.h create mode 100644 arch/unicore32/include/uapi/asm/posix_types.h -- 1.8.2.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
