Clean up and rename fb_pgprotect() to work without struct file. Then refactor the implementation for PowerPC. This change has been discussed at [1] in the context of refactoring fbdev's mmap code. The first two patches update fbdev and replace fbdev's fb_pgprotect() with pgprot_framebuffer() on all architectures. The new helper's stream- lined interface enables more refactoring within fbdev's mmap implementation. Patches 3 to 5 adapt PowerPC's internal interfaces to provide phys_mem_access_prot() that works without struct file. Neither the architecture code or fbdev helpers need the parameter. v4: * fix commit message (Christophe) v3: * rename fb_pgrotect() to pgprot_framebuffer() (Arnd)
I had another look today, and everything look good to me now. Whole series Reviewed-by: Arnd Bergmann <arnd@xxxxxxxx>
