Is that intentional? Can you briefly explain the backgroundfor this change?Patch 01 of this patchset changes the generic fb_pgprotect() to set pgprot_writecombine(). So on SH, there should be no change at all.
In case you didn't receive that patch: https://patchwork.freedesktop.org/patch/532493/?series=116157&rev=3
