The implementation of each helper depends on the architecture. It's still all located in fbdev's main header file . Move all of it into each archtecture's , with shared code in . The first patch a simple whitespace cleanup. Until now, contained an include of . 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 . Source files that use framebuffer I/O helpers, such as fb_readl(), now include . The latter now includes internally. Patch 5 moves the framebuffer I/O helpers from 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.
