[ Upstream commit 5c41aaad409c097cf1ef74f2c649fed994744ef5 ] Building drivers/mtd/nand/raw/nandsim.c on arch/hexagon/ produces a printk format build warning. This is due to hexagon's ffs() being coded as returning long instead of int. Fix the printk format warning by changing all of hexagon's ffs() and fls() functions to return int instead of long. The variables that they return are already int instead of long. This return type matches the return type in <asm-generic/bitops/>. ../drivers/mtd/nand/raw/nandsim.c: In function 'init_nandsim': ../drivers/mtd/nand/raw/nandsim.c:760:2: warning: format '%u' expects argument of type 'unsigned int', but argument 2 has type 'long int' [-Wformat] There are no ffs() or fls() allmodconfig build errors after making this change.

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.
