_PAGE_NO_CACHE is a platform specific flag. In addition, this flag is misleading because one would think it requests a noncached page whereas a noncached page is _PAGE_NO_CACHE | _PAGE_GUARDED _PAGE_NO_CACHE alone means write combined noncached page, so lets use ioremap_wc() instead. _PAGE_WRITETHRU is also platform specific flag. Use ioremap_wt() instead. Signed-off-by: Christophe Leroy <redacted>
After reading patch #1 this one LGTM. Acked-by: Bartlomiej Zolnierkiewicz <redacted>
