Main changes since v7 are: - Added gettime64 on PPC32 This series applies on today's powerpc/merge branch. See the last patches for details on changes and performance. Christophe Leroy (8): powerpc/vdso64: Switch from __get_datapage() to get_datapage inline macro powerpc/vdso: Remove __kernel_datapage_offset and simplify __get_datapage() powerpc/vdso: Remove unused \tmp param in __get_datapage() powerpc/processor: Move cpu_relax() into asm/vdso/processor.h powerpc/vdso: Prepare for switching VDSO to generic C implementation. powerpc/vdso: Switch VDSO to generic C implementation. lib/vdso: force inlining of __cvdso_clock_gettime_common() powerpc/vdso: Provide __kernel_clock_gettime64() on vdso32 arch/powerpc/Kconfig | 2 + arch/powerpc/include/asm/clocksource.h | 7 + arch/powerpc/include/asm/processor.h | 10 +- arch/powerpc/include/asm/vdso/clocksource.h | 7 + arch/powerpc/include/asm/vdso/gettimeofday.h | 175 +++++++++++ arch/powerpc/include/asm/vdso/processor.h | 23 ++ arch/powerpc/include/asm/vdso/vsyscall.h | 25 ++ arch/powerpc/include/asm/vdso_datapage.h | 50 ++-- arch/powerpc/kernel/asm-offsets.c | 49 +-- arch/powerpc/kernel/time.c | 91 +----- arch/powerpc/kernel/vdso.c | 58 +--- arch/powerpc/kernel/vdso32/Makefile | 32 +- arch/powerpc/kernel/vdso32/cacheflush.S | 2 +- arch/powerpc/kernel/vdso32/config-fake32.h | 34 +++ arch/powerpc/kernel/vdso32/datapage.S | 7 +- arch/powerpc/kernel/vdso32/gettimeofday.S | 300 +------------------ arch/powerpc/kernel/vdso32/vdso32.lds.S | 8 +- arch/powerpc/kernel/vdso32/vgettimeofday.c | 35 +++ arch/powerpc/kernel/vdso64/Makefile | 23 +- arch/powerpc/kernel/vdso64/cacheflush.S | 9 +- arch/powerpc/kernel/vdso64/datapage.S | 31 +- arch/powerpc/kernel/vdso64/gettimeofday.S | 243 +-------------- arch/powerpc/kernel/vdso64/vdso64.lds.S | 7 +- arch/powerpc/kernel/vdso64/vgettimeofday.c | 29 ++ lib/vdso/gettimeofday.c | 2 +- 25 files changed, 460 insertions(+), 799 deletions(-) create mode 100644 arch/powerpc/include/asm/clocksource.h create mode 100644 arch/powerpc/include/asm/vdso/clocksource.h create mode 100644 arch/powerpc/include/asm/vdso/gettimeofday.h create mode 100644 arch/powerpc/include/asm/vdso/processor.h create mode 100644 arch/powerpc/include/asm/vdso/vsyscall.h create mode 100644 arch/powerpc/kernel/vdso32/config-fake32.h create mode 100644 arch/powerpc/kernel/vdso32/vgettimeofday.c create mode 100644 arch/powerpc/kernel/vdso64/vgettimeofday.c -- 2.25.0
