[PATCH v2 2/2] powerpc/perf: Power11 Performance Monitoring support

Base enablement patch to register performance monitoring hardware support for Power11. Most of fields are copied from power10_pmu struct for power11_pmu struct. Signed-off-by: Madhavan Srinivasan --- Changelog v1: - Copied power10 struct for power11 with name change

[PATCH v2 1/2] powerpc: Add Power11 architected and raw mode

reg.h is updated with Power11 pvr. pvr_mask value of 0x0F07 means we are arch v3.1 compliant. This is used by phyp and kvm when booting as a pseries guest to detect and enable the appropriate hwcap, facility bits and PMU related fields. Copied most of fields from Power10 table entry and added

[PATCH v2] powerpc: Avoid nmi_enter/nmi_exit in real mode interrupt.

nmi_enter()/nmi_exit() touches per cpu variables which can lead to kernel crash when invoked during real mode interrupt handling (e.g. early HMI/MCE interrupt handler) if percpu allocation comes from vmalloc area. Early HMI/MCE handlers are called through DEFINE_INTERRUPT_HANDLER_NMI() wrapper

[PATCH 4/4] powerpc: pseries: make suspend_subsys const

Now that the driver core can properly handle constant struct bus_type, move the suspend_subsys variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime. Cc: Greg Kroah-Hartman Suggested-by: Greg Kroah-Hartman Signed-off-by: Ricardo B.

[PATCH 3/4] powerpc: pseries: make cmm_subsys const

Now that the driver core can properly handle constant struct bus_type, move the cmm_subsys variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime. Cc: Greg Kroah-Hartman Suggested-by: Greg Kroah-Hartman Signed-off-by: Ricardo B.

[PATCH 2/4] powerpc: ps3: make ps3_system_bus_type const

Now that the driver core can properly handle constant struct bus_type, move the ps3_system_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime. Cc: Greg Kroah-Hartman Suggested-by: Greg Kroah-Hartman Signed-off-by: Ricardo
