    hvm/params: add a new delivery type for event-channel in 
HVM_PARAM_CALLBACK_IRQ
    
    This new delivery type which is for ARM shares the same value with
    HVM_PARAM_CALLBACK_TYPE_VECTOR which is for x86.
    
    val[15:8] is flag: val[7:0] is a PPI.
    To the flag, bit 8 stands the interrupt mode is edge(1) or level(0) and
    bit 9 stands the interrupt polarity is active low(1) or high(0).

    x86/hvm/viridian: fix APIC assist page leak
    
    Commit a6f2cdb6 "keep APIC assist page mapped..." introduced a page
    leak because it relied on viridian_vcpu_deinit() always being called
    to release the page mapping. This does not happen in the case a normal
    domain shutdown.
    
    This patch fixes the problem by introducing a new function,
    viridian_domain_deinit(), which will iterate through the vCPUs and
    release any page mappings still present.

    x86/hvm/viridian: save APIC assist vector
    
    If any vcpu has a pending APIC assist when the domain is suspended
    then the vector needs to be saved. If this is not done then it's
    possible for the vector to remain pending in the vlapic ISR
    indefinitely after resume.
    
    This patch adds code to save the APIC assist vector value in the
    viridian vcpu save record. This means that the record is now zero-
    extended on load and, because this implies a loaded value of
    zero means nothing is pending (for backwards compatibility with
    hosts not implementing APIC assist), the rest of the viridian APIC
    assist code is adjusted to treat a zero value in this way. A
    check has therefore been added to viridian_start_apic_assist() to
    prevent the enlightenment being used for vectors < 0x10 (which
    are illegal for an APIC).

    Anthony Perard to co-maintain qemu
    
    I nominate Anthony Perard as qemu-xen co-maintainer. He has been doing a
    lot of QEMU work over the years and in fact he is the original author of
    the Xen enablement code in upstream QEMU.
    
    As qemu-xen co-maintainer, he could help me manage the qemu-xen trees
    and promptly backport all the relevant commits from upstream QEMU.

    x86: fix information leak on AMD CPUs
    
    The fix for XSA-52 was wrong, and so was the change synchronizing that
    new behavior to the FXRSTOR logic: AMD's manuals explictly state that
    writes to the ES bit are ignored, and it instead gets calculated from
    the exception and mask bits (it gets set whenever there is an unmasked
    exception, and cleared otherwise). Hence we need to follow that model
    in our workaround.
    
    This is CVE-2016-3158 / CVE-2016-3159 / XSA-172.
