Add xcall/xint support for arm64. Changes in v2: - Avoid enable xint without GICv3 enabled. - Fix cpucap KABI break. - Fix missing openeuler_defconfig update. - Correct the marco control for SECURITY_FEATURE_BYPASS in entry.S - exit_to_user_mode_prepare_xcall() -> xcall_exit_to_user_mode_prepare() Jinjie Ruan (2): arm64: Introduce Xint software solution arm64: Add debugfs dir for xint Yipeng Zou (2): arm64: Introduce xcall a faster svc exception handling arm64: Faster SVC exception handler with xcall arch/Kconfig | 64 ++++++++++ arch/arm64/Kconfig | 2 + arch/arm64/configs/openeuler_defconfig | 4 + arch/arm64/kernel/asm-offsets.c | 3 + arch/arm64/kernel/cpufeature.c | 54 ++++++++ arch/arm64/kernel/entry-common.c | 162 ++++++++++++++++++++++++ arch/arm64/kernel/entry.S | 164 ++++++++++++++++++++++++- arch/arm64/tools/cpucaps | 4 +- drivers/irqchip/irq-gic-v3.c | 123 +++++++++++++++++++ fs/proc/base.c | 112 +++++++++++++++++ include/linux/hardirq.h | 5 + include/linux/irqchip/arm-gic-v3.h | 13 ++ include/linux/sched.h | 4 + kernel/fork.c | 17 +++ kernel/irq/debugfs.c | 33 +++++ kernel/irq/internals.h | 18 +++ kernel/irq/proc.c | 6 + kernel/softirq.c | 47 +++++++ 18 files changed, 830 insertions(+), 5 deletions(-) -- 2.34.1

[PATCH openEuler-22.03-LTS-SP1] nilfs2: fix kernel bug due to missing clearing of checked flag
