    xen/arm: Flush TLBs before turning on the MMU to avoid stale entries
    
    We don't know what is the state of the TLBs when booting Xen. To avoid
    stale entries, it is necessary to flush the TLBs before turning on the
    MMU.

    xen/arm: vgic: Make sure the number of SPIs is a multiple of 32
    
    The vGIC relies on having a pending_irq available for every IRQs
    described in the ranks. As each rank describes 32 interrupts, we need to
    make sure the number of SPIs is a multiple of 32.

    tools/libxc: Fix restoration of PV MSRs after migrate
    
    There are two bugs in process_vcpu_msrs() which clearly demonstrate that I
    didn't test this bit of Migration v2 very well when writing it...
    
    vcpu->msrsz is always expected to be a multiple of xen_domctl_vcpu_msr_t
    records in a spec-compliant stream, so the modulo yields 0 for the 
msr_count,
    rather than the actual number sent in the stream.
    
    Passing 0 for the msr_count causes the hypercall to exit early, and hides 
the
    fact that the guest handle is inserted into the wrong field in the domctl
    union.
    
    The reason that these bugs have gone unnoticed for so long is that the only
    MSRs passed like this for PV guests are the AMD DBGEXT MSRs, which only 
exist
    in fairly modern hardware, and whose use doesn't appear to be implemented in
    any contemporary PV guests.

    x86/hvm: Disallow the creation of HVM domains without Local APIC emulation
    
    There are multiple problems, not necesserily limited to:
    
     * Guests which configure event channels via 
hvmop_set_evtchn_upcall_vector(),
       or which hit %cr8 emulation will cause Xen to fall over a NULL 
vlapic->regs
       pointer.
    
     * On Intel hardware, disabling the TPR_SHADOW execution control without
       reenabling CR8_{LOAD,STORE} interception means that the guests %cr8
       accesses interact with the real TPR.  Amongst other things, setting the
       real TPR to 0xf blocks even IPIs from interrupting this CPU.
    
     * On hardware which sets up the use of Interrupt Posting, including
       IOMMU-Posting, guests run without the appropriate non-root configuration,
       which at a minimum will result in dropped interrupts.
    
    Whether no-LAPIC mode is of any use at all remains to be seen.
    
    This is XSA-256.

    gnttab: don't blindly free status pages upon version change
    
    There may still be active mappings, which would trigger the respective
    BUG_ON(). Split the loop into one dealing with the page attributes and
    the second (when the first fully passed) freeing the pages. Return an
    error if any pages still have pending references.
    
    This is part of XSA-255.

    gnttab/ARM: don't corrupt shared GFN array
    
    ... by writing status GFNs to it. Introduce a second array instead.
    Also implement gnttab_status_gmfn() properly now that the information is
    suitably being tracked.
    
    While touching it anyway, remove a misguided (but luckily benign) upper
    bound check from gnttab_shared_gmfn(): We should never access beyond the
    bounds of that array.

    memory: don't implicitly unpin for decrease-reservation
    
    It very likely was a mistake (copy-and-paste from domain cleanup code)
    to implicitly unpin here: The caller should really unpin itself before
    (or after, if they so wish) requesting the page to be removed.
