    xen/timers: Document and improve the representation of the timer heap 
    The {GET,SET}_HEAP_{SIZE,LIMIT}() macros implement some completely
    undocumented pointer misuse to store the size and limit information.  In
    practice, heap[0] is never a timer pointer, and used to stash the metadata
    Extend the HEAP OPERATIONS comment to include this detail.  Introduce a
    structure representing the heap metadata, and a static inline function to
    perfom the type punning.
    Replace all of the above macros with an equivelent expression involving the
    heap_metadata() helper.  Note that I deliberately haven't rearranged the
    surrounding code - this allows the correctness of the transformation to be
    checked by confirming that the compiled binary is identical.
    This also removes two cases of a macro argument with side effects, which 
    worked correctly because the arguments were only evaluated once.
    Finally, fix up the type of dummy_heap.  The old code functioned correctly,
    but only by virtue of confusing a discrete object and a single-entry array.
    Change its type to match the intended semantics, and drop the redundant
    initialisation in timer_init().
    No functional change.

    xen/sched: fix credit2 smt idle handling
    Credit2's smt_idle_mask_set() and smt_idle_mask_clear() are used to
    identify idle cores where vcpus can be moved to. A core is thought to
    be idle when all siblings are known to have the idle vcpu running on
    Unfortunately the information of a vcpu running on a cpu is per
    runqueue. So in case not all siblings are in the same runqueue a core
    will never be regarded to be idle, as the sibling not in the runqueue
    is never known to run the idle vcpu.
    Use a credit2 specific cpumask of siblings with only those cpus
    being marked which are in the same runqueue as the cpu in question.

    libx86: Recalculate synthesised cpuid_policy fields when appropriate
    When filling a policy, either from CPUID or an incomming leaf stream,

    x86/cpuid: Drop get_cpu_vendor() completely
    get_cpu_vendor() tries to do a number of things, and ends up doing none of
    them well.
    For calculating the vendor itself, use x86_cpuid_lookup_vendor() which is
    implemented in a far more efficient manner than looping over cpu_devs[].
    For setting up this_cpu, set it up once on the BSP only, rather than
    latest-takes-precident across the APs.  Such a system is probably not going 
    boot, but this feels like a less dangerous course of action.  Adjust the
    printed errors to be more clear in the mismatch case.
    This removes the only user of cpu_dev->c_ident[], so drop that field as

    CI: Add a CentOS 6 container and build jobs
    CentOS 6 is probably the most frequently broken build, so adding it to CI
    would be a very good move.
    One problem is that CentOS 6 comes with Python 2.6, and Qemu requires 2.7.
    There appear to be no sensible ways to get Python 2.7 into a CentOS 6
    environments, so modify the build script to skip the Qemu upstream build
    instead.  Additionally, SeaBIOS requires GCC 4.6 or later, so skip it as
