From 24e4a8c3e8868874835b0f1ad6dd417341e99822 Mon Sep 17 00:00:00 2001 From: John Stultz Date: Wed, 16 Jul 2014 21:03:53 +0000 Subject: ktime: Kill non-scalar ktime_t implementation for 2038 The non-scalar ktime_t implementation is basically a timespec which has to be changed to support dates past 2038 on 32bit systems. This patch removes the non-scalar ktime_t implementation, forcing the scalar s64 nanosecond version on all architectures. This may have additional performance overhead on some 32bit systems when converting between ktime_t and timespec structures, however the majority of 32bit systems (arm and i386) were already using scalar ktime_t, so no performance regressions will be seen on those platforms. On affected platforms, I'm open to finding optimizations, including avoiding converting to timespecs where possible. [ tglx: We can now cleanup the ktime_t.tv64 mess, but thats a different issue and we can throw a coccinelle script at it ] Signed-off-by: John Stultz Signed-off-by: Thomas Gleixner Signed-off-by: John Stultz --- arch/hexagon/Kconfig | 1 - 1 file changed, 1 deletion(-) (limited to 'arch/hexagon/Kconfig') diff --git a/arch/hexagon/Kconfig b/arch/hexagon/Kconfig index 0fd6138f6203..4dc89d1f9c48 100644 --- a/arch/hexagon/Kconfig +++ b/arch/hexagon/Kconfig @@ -23,7 +23,6 @@ config HEXAGON select GENERIC_IOMAP select GENERIC_SMP_IDLE_THREAD select STACKTRACE_SUPPORT - select KTIME_SCALAR select GENERIC_CLOCKEVENTS select GENERIC_CLOCKEVENTS_BROADCAST select MODULES_USE_ELF_RELA -- cgit
