The 8xx cannot access the TBL and TBU registers using mfspr/mtspr It must be accessed using mftb/mftbu Due to this, there is a number of places with #ifdef CONFIG_8xx This patch defines new macros MFTBL(x) and MFTBU(x) on the same model as MFTB(x) and tries to make use of them as much as possible. In arch/powerpc/include/asm/timex.h, we also remove the ifdef for the asm() operands as the compiler doesn't mind unused operands Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
