An SError may also become pending,\nand will be synchronised by KVM. KVM notes the exception type, and whether\nan SError was synchronised in exit_code.\n\nWhen an exception other than an IRQ occurs, fixup_guest_exit() updates\nvcpu->arch.fault.esr_el2 from the hardware register. When an SError was\nsynchronised, the vcpu esr value is used to determine if the exception\nwas due to an HVC. If so, ELR_EL2 is moved back one instruction. This\nis so that KVM can process the SError first, and re-execute the HVC if\nthe guest survives the SError.\n\nBut if an IRQ synchronises an SError, the vcpu's esr value is stale.\nIf the previous non-IRQ exception was an HVC, KVM will corrupt ELR_EL2,\ncausing an unrelated guest instruction to be executed twice.\n\nCheck ARM_EXCEPTION_CODE() before messing with ELR_EL2, IRQs don't\nupdate this register so don't need to check."
