These all predate the ioremap_*() variants, and can be converted to either ioremap_nocache() or ioremap_wt(). However, PPC doesn't implement ioremap_wt() yet, so asm-generic will fall back to the less-efficient nocache variant. PPC does support __ioremap(..., _PAGE_WRITETHRU), so adding a wrapper is trivial. > Signed-off-by: Bjorn Helgaas <bhelg...@google.com> > Reviewed-by: Arnd Bergmann <a...@arndb.de> Regardless, Acked-by: Geert Uytterhoeven <ge...@linux-m68k.org> Gr{oetje,eeting}s, Geert -- Geert Uytterhoeven -- There's lots of Linux beyond ia32 -- ge...@linux-m68k.org In personal conversations with technical people, I call myself a hacker.
