From: Borislav Petkov <bp@suse.de> Hi, here's the final version of the pile we've been working on for a while now, trying to remove that rdmsr on the idle path. @jolsa: just wait until it lands in tip and then you can run it on your box. Thanks. Borislav Petkov (2): x86/cpufeature: Provide helper to set bugs bits x86/amd: Simplify AMD E400 aware idle routine Thomas Gleixner (3): x86/bugs: Separate AMD E400 erratum and C1E bug x86/amd: Check for the C1E bug post ACPI subsystem init x86: Remove empty idle.h header arch/x86/include/asm/acpi.h | 2 +- arch/x86/include/asm/apic.h | 1 - arch/x86/include/asm/cpufeature.h | 1 + arch/x86/include/asm/cpufeatures.h | 2 + arch/x86/include/asm/idle.h | 6 -- arch/x86/include/asm/processor.h | 3 +- arch/x86/kernel/apic/apic.c | 3 +- arch/x86/kernel/apic/io_apic.c | 1 - arch/x86/kernel/cpu/amd.c | 20 +++--- arch/x86/kernel/cpu/common.c | 1 - arch/x86/kernel/cpu/mcheck/mce_amd.c | 1 - arch/x86/kernel/cpu/mcheck/therm_throt.c | 1 - arch/x86/kernel/cpu/mcheck/threshold.c | 1 - arch/x86/kernel/cpu/mshyperv.c | 1 - arch/x86/kernel/irq.c | 1 - arch/x86/kernel/irq_64.c | 1 - arch/x86/kernel/kvm.c | 1 - arch/x86/kernel/process.c | 102 +++++++++++++++---------------- arch/x86/kernel/process_32.c | 1 - arch/x86/kernel/process_64.c | 1 - arch/x86/kernel/smpboot.c | 2 - arch/x86/platform/uv/tlb_uv.c | 1 - drivers/acpi/processor_idle.c | 2 +- drivers/thermal/intel_powerclamp.c | 1 - drivers/xen/events/events_base.c | 1 - init/main.c | 3 + 26 files changed, 74 insertions(+), 87 deletions(-) delete mode 100644 arch/x86/include/asm/idle.h -- 2.11.0
