Fbdev provides helpers for framebuffer I/O, such as fb_readl(), fb_writel() or fb_memcpy_to_fb(). The implementation of each helper depends on the architecture. It's still all located in fbdev's main header file <linux/fb.h>. Move all of it into each archtecture's <asm/fb.h>, with shared code in <asm-generic/fb.h>. The first patch a simple whitespace cleanup. Until now, <linux/fb.h> contained an include of <asm/io.h>. As this will go away patches 2 to 4 prepare include statements in the various drivers. Source files that use regular I/O helpers, such as readl(), now include <linux/io.h>. Source files that use framebuffer I/O helpers, such as fb_readl(), now include <asm/fb.h>. The latter now includes <linux/io.h> internally. Patch 5 moves the framebuffer I/O helpers from <linux/fb.h> into the various architecture headers. The common case, where the framebuffer is located in I/O memory, serves as the generic implemenation. The patchset has been built for a variety of platforms, such as x86-64, arm, aarch64, ppc64, parisc, m64k, mips and sparc.
