Currently powerpc's asm/io.h includes linux/io.h, and linux/io.h includes asm/io.h. This can cause problems because depending on which is included first the order of definitions between the two files will change. The include of linux/io.h was added back in 2008 in commitb41e5fffe8("[POWERPC] devres: Add devm_ioremap_prot()"). It's not entirely clear it was needed then, but devm_ioremap_prot() has since been removed entirely as unused, indedd24a12f("powerpc: Remove unused devm_ioremap_prot()"). So it seems to be unnecessary and can potentially cause problems, so remove the include of linux/io.h from asm/io.h 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.
