    xen/arm: p2m: Fix incorrect mapping of superpages
    The same set of functions is used to set as well as to clean P2M
    entries, except for clean operations (INVALID_MFN ~0UL) is passed as a
    parameter. Unfortunately, when calculating an appropriate target order
    for a particular mapping INVALID_MFN is taken into account which leads
    to 4K page target order being set each time even for 2MB and 1GB
    This will result to break down the superpage into 4K mappings and leave
    empty tables allocated.
    This was introduced by commit 2ef3e36ec7 "xen/arm: p2m: Introduce
    p2m_set_entry and __p2m_set_entry".

    vgic: refuse irq migration when one is already in progress
    When an irq migration is already in progress, but not yet completed
    (GIC_IRQ_GUEST_MIGRATING is set), refuse any other irq migration
    requests for the same irq.
    This patch implements this approach by returning success or failure from
    vgic_migrate_irq, and avoiding irq target changes on failure. It prints
    a warning in case the irq migration fails.
    It also moves the clear_bit of GIC_IRQ_GUEST_MIGRATING to after the
    physical irq affinity has been changed so that all operations regarding
    irq migration are completed.

    arm: remove irq from inflight, then change physical affinity
    This patch fixes a potential race that could happen when
    gic_update_one_lr and vgic_vcpu_inject_irq run simultaneously.
    When GIC_IRQ_GUEST_MIGRATING is set, we must make sure that the irq has
    been removed from inflight before changing physical affinity, to avoid
    concurrent accesses to p->inflight, as vgic_vcpu_inject_irq will take a
    different vcpu lock.

    xen/arm: Survive unknown traps from guests
    Currently we crash Xen if we see an ESR_EL2.EC value we don't recognise.
    As configurable disables/enables are added to the architecture
    (controlled by RES1/RESO bits respectively), with associated synchronous
    exceptions, it may be possible for a guest to trigger exceptions with
    classes that we don't recognise.
    While we can't service these exceptions in a manner useful to the guest,
    we can avoid bringing down the host. Per ARM DDI 0487A.k_iss10775, page
    D7-1937, EC values within the range 0x00 - 0x2c are reserved for future
    use with synchronous exceptions, and EC within the range 0x2d - 0x3f may
    be used for either synchronous or asynchronous exceptions.
    The patch makes Xen handle any unknown EC by injecting an UNDEFINED
    exception into the guest, with a corresponding (ratelimited) warning in
    the log.
    This patch is based on Linux commit f050fe7a9164 "arm: KVM: Survive unknown
    traps from the guest".

    xen/arm: do_trap_hypervisor: Separate hypervisor and guest traps
    The function do_trap_hypervisor is currently handling both trap coming
    from the hypervisor and the guest. This makes difficult to get specific
    behavior when a trap is coming from either the guest or the hypervisor.
    Split the function into two parts:
        - do_trap_guest_sync to handle guest traps
        - do_trap_hyp_sync to handle hypervisor traps
    On AArch32, the Hyp Trap Exception provides the standard mechanism for
    trapping Guest OS functions to the hypervisor (see B1.14.1 in ARM DDI
    0406C.c). It cannot be generated when generated when the processor is in
    Hyp Mode, instead other exception will be used. So it is fine to replace
    the call to do_trap_hypervisor by do_trap_guest_sync.
    For AArch64, there are two distincts exception depending whether the
    exception was taken from the current level (hypervisor) or lower level
    Note that the unknown traps from guests will lead to panic Xen. This is
    already behavior and is left unchanged for simplicy. A follow-up patch
    will address that.

    xen/arm: Save ESR_EL2 to avoid using mismatched value in syndrome check
    Xen will do exception syndrome check while some types of exception
    take place in EL2. The syndrome check code read the ESR_EL2 register
    directly, but in some situation this register maybe overridden by
    nested exception.
    For example, if we re-enable IRQ before reading ESR_EL2 which means
    Xen may enter in IRQ exception mode and return the processor with
    clobbered ESR_EL2 (See ARM ARM DDI 0487A.j D7.2.25)
    In this case the guest exception syndrome has been overridden, we will
    check the syndrome for guest sync exception with an incorrect ESR_EL2
    value. So we want to save ESR_EL2 to cpu_user_regs as soon as the
    exception takes place in EL2 to avoid using an incorrect syndrome value.
    In order to save ESR_EL2, we added a 32-bit member hsr to cpu_user_regs.
    But while saving registers in trap entry, we use stp to save ELR and
    CPSR at the same time through 64-bit general registers. If we keep this
    code, the hsr will be overridden by upper 32-bit of CPSR. So adjust the
    code to use str to save ELR in a separate instruction and use stp to
    save CPSR and HSR at the same time through 32-bit general registers.
    This change affects the registers restore in trap exit, we can't use the
    ldp to restore ELR and CPSR from stack at the same time. We have to use
    ldr to restore them separately.
