Without this, the ARM arch timer\n does not work on secondary CPU cores.\n This patch depends on \"[PATCH v2] ARM: shmobile: rcar-gen2: Correct\n arch timer frequency on RZ/G1E\".\n - The third patch adds the required infrastructure (APMU device node\n and corresponding enable-method) to DT.\n Obviously this must not be applied on a branch that does not contain\n the first two patches!\n\nDue to dependencies, I think it is easiest if the ARM maintainers provide\ntheir Acked-by for patch 1, so the whole series can go in through Simon's\nRenesas tree.\n\nChanges compared to v2:\n - Replace \"isb\" by \"instr_sync\" to fix the arm v6 build (e.g.\n allmodconfig),\n\nChanges compared to v1:\n - New patch \"[PATCH v2 1/3] ARM: Add definition for monitor mode\",\n - Initialize CNTVOFF on Cortex-A15, too,\n - Use *_MODE definitions instead of hardcoded values,\n - Reduce duplication by calling the asm version from C,\n - Always build headsmp-apmu.o on R-Car Gen2.\n\nThis has been tested on r8a7794/alt (dual Cortex-A7), and regression-tested\non r8a7790/lager (quad Cortex-A15), and r8a7791/koelsch, r8a7791/porter,\nr8a7792/blanche, and r8a7793/gose (dual Cortex-A15).\n\nThanks!\n\nGeert Uytterhoeven (2):\n ARM: Add definition for monitor mode\n ARM: shmobile: rcar-gen2: Make sure CNTVOFF is initialized on CA7/15\n\nSergei Shtylyov (1):\n ARM: dts: r8a7794: Add SMP support\n\n arch/arm/boot/dts/r8a7794.dtsi | 7 ++++++\n arch/arm/include/uapi/asm/ptrace.h | 1 +\n arch/arm/mach-shmobile/Makefile | 1 +\n arch/arm/mach-shmobile/common.h | 2 ++\n arch/arm/mach-shmobile/headsmp-apmu.S | 37 ++++++++++++++++++++++++++++++++\n arch/arm/mach-shmobile/platsmp-apmu.c | 2 +-\n arch/arm/mach-shmobile/setup-rcar-gen2.c | 20 ++---------------\n 7 files changed, 51 insertions(+), 19 deletions(-)\n create mode 100644 arch/arm/mach-shmobile/headsmp-apmu.S"}
