    x86/boot: Make alternative patching NMI-safe
    During patching, there is a very slim risk that an NMI or MCE interrupt in 
    middle of altering the code in the NMI/MCE paths, in which case bad things
    will happen.
    The NMI risk can be eliminated by running the patching loop in NMI context, 
    which point the CPU will defer further NMIs until patching is complete.

    x86/mm: Add debug code to detect illegal page_lock and put_page_type 
    The fix for XSA-242 depends on the same cpu never calling
    _put_page_type() while holding a page_lock() for that page; doing so
    may cause a deadlock under the right conditions.
    Furthermore, even before that, there was never any discipline for the
    order in which page locks are grabbed; if there are any paths that
    grab the locks for two different pages at once, we risk creating the
    conditions for a deadlock to occur.
    These are believed to be safe, because it is believed that:
    1. No hypervisor paths ever lock two pages at once, and
    2. We never call _put_page_type() on a page while holding its page lock.
    Add a check to debug builds to catch any violations of these

    x86/spec_ctrl: Fix determination of when to use IBRS
    The original version of this logic was:
         * On Intel hardware, we'd like to use retpoline in preference to
         * IBRS, but only if it is safe on this hardware.
        else if ( boot_cpu_has(X86_FEATURE_IBRSB) )
            if ( retpoline_safe() )
                thunk = THUNK_RETPOLINE;
                ibrs = true;
    but it was changed by a request during review.  Sadly, the result is buggy 
    it breaks the later fallback logic by allowing IBRS to appear as available
    when in fact it isn't.
    This in practice means that on repoline-unsafe hardware without IBRS, we
    select THUNK_JUMP despite intending to select THUNK_RETPOLINE.

    libxc: don't fail domain creation when unpacking initrd fails
    At least Linux kernels have been able to work with gzip-ed initrd for
    quite some time; initrd compressed with other methods aren't even being
    attempted to unpack. Furthermore the unzip-ing routine used here isn't
    capable of dealing with various forms of concatenated files, each of
    which was gzip-ed separately (it is this particular case which has been
    the source of observed VM creation failures).
    Hence, if unpacking fails, simply hand the compressed blob to the guest
    as is.
