    x86/mm/pat: Add set_memory_wt() for Write-Through type · 623dffb2
    Toshi Kani authored
    Now that reserve_ram_pages_type() accepts the WT type, add
    set_memory_wt(), set_memory_array_wt() and set_pages_array_wt()
    in order to be able to set memory to Write-Through page cache
    mode.
    
    Also, extend ioremap_change_attr() to accept the WT type.
