    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.

    tools/libxc: Avoid generating inappropriate zero-content records
    
    The code as written attempted to elide zero-content records, as such records
    serve no purpose but come with a performance hit.  Unfortunately, in the 
case
    where the hypervisor reported max size is non-zero, but the actual size is
    zero, the record is not elided.
    
    This previously tripped up the sanity checks in the restore side of 
migration,
    but as the underlying reasons for eliding the records in the first place are
    still valid, fix the elision logic.

    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.
    
    This is XSA-252.
