    x86/mm, asm-generic: Add ioremap_wt() for creating Write-Through mappings · d838270e
    Toshi Kani authored
    Add ioremap_wt() for creating Write-Through mappings on x86. It
    follows the same model as ioremap_wc() for multi-arch support.
    Define ARCH_HAS_IOREMAP_WT in the x86 version of io.h to
    indicate that ioremap_wt() is implemented on x86.
    Also update the PAT documentation file to cover ioremap_wt().
