flush_dcache_page() is only a few lines, it is worth inlining. ia64, csky, mips, openrisc and riscv have a similar flush_dcache_page() and inline it. On pmac32_defconfig, we get a small size reduction. On ppc64_defconfig, we get a very small size increase. In both case that's in the noise (less than 0.1%). text data bss dec hex filename 18991155 5934744149762426423523 19330e3 vmlinux64.before 189948295936732149762426429185 1934701 vmlinux64.after 9150963 2467502 184548 11803013 b41985 vmlinux32.before91496892467302 184548 11801539 b413c3 vmlinux32.after Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/21c417488b70b7629dae316539fb7bb8bdef4fdd.1617895813.git.christophe.leroy@csgroup.eu
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
