    AMD/IOMMU: Treat head/tail pointers as byte offsets
    
    The MMIO registers as already byte offsets.  Using them in this form removes
    the need to shift their values for use.
    
    It is also inefficient to store both entries and alloc_size (which only 
differ
    by entry_size).  Rename alloc_size to size, and drop entries entirely, which
    simplifies the allocation/deallocation helpers slightly.
    
    Mark send_iommu_command() and invalidate_iommu_all() as static, as they have
    no external declaration or callers.

    xen/sched: remove pointless BUG_ON() in credit2
    
    The BUG_ON() at the top of csched2_context_saved() is completely
    pointless, as the ASSERT() just following it catches the same problem
    already.
