Regressions :-(

Tests which did not succeed and are blocking:

    xentrace: correct overflow check for number of per-cpu trace pages
    
    The calculated number of per-cpu trace pages is stored in t_info and
    shared with tools like xentrace. Since its an u16 the value may
    overflow because the current check is based on u32.  Using the u16
    means each cpu could in theory use up to 256MB as trace
    buffer. However such a large allocation will currently fail on x86 due
    to the MAX_ORDER limit.  Check both max theoretical number of pages
    per cpu and max number of pages reachable by struct t_buf->prod/cons
    variables with requested number of pages.

    svm: implement instruction fetch part of DecodeAssist (on #PF/#NPF)
    
    Newer SVM implementations (Bulldozer) copy up to 15 bytes from the
    instruction stream into the VMCB when a #PF or #NPF exception is
    intercepted. This patch makes use of this information if available.
    This saves us from a) traversing the guest's page tables, b) mapping
    the guest's memory and c) copy the instructions from there into the
    hypervisor's address space.
    This speeds up #NPF intercepts quite a lot and avoids cache and TLB
    trashing.

    svm: decode-assists feature must depend on nextrip feature.
    
    ...since the decode-assist fast paths assume nextrip vmcb field is
    valid.
