Hi guys, This is GengDongjiu's get/set events series[0], with additional plumbing for 32bit. This series adds the get/set events API to KVM for arm/arm64 so that user-space can migrate pending SError, (which KVM may have made pending as part of its device emulation), and for RAS make a new SError with a specific ESR value pending. (Only systems with the v8.2 RAS Extensions can specify an ESR, KVM advertises this capability with a new cap: KVM_CAP_ARM_INJECT_SERROR_ESR) User-space can use this for emulation of the v8.2 CPU RAS features (using error nodes backed by mmio) or as part of NOTIFY_SEI which extends a v8.2 RAS SError to also have firmware-first CPER records.
