    Subjectis pci_alloc_consistent() really consistent on a pentium?
    If IA32 builds use the i386 version of
    pci_alloc_consistent(), how is the memory provided by
    this function really write-thru (on a pentium) since
    it appears to only set up the default mapping
    (PCD/PWT==0)? In contrast, pgprot_noncached() and
    pci_mmap_page_range() explicitly set these bits on a
    pentium (i.e. when boot_cpu_data.x86 > 3). Or am I
    missing something?

    Please CC me on the response.
