Subject: [PATCH v12 6/10] video/fbdev, asm/io.h: Remove ioremap_writethrough()
This patch removes the callers of ioremap_writethrough() by
replacing them with ioremap_wt() in three drivers under
drivers/video/fbdev. It then removes ioremap_writethrough()
defined in some architecture's asm/io.h, frv, m68k, microblaze,
and tile.
