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.

This reverts commit 5bdcd510. The macro based workarounds for GCC's inlining bugs caused regressions: distcc and other distro build setups broke, and the fixes are not easy nor will they solve regressions on already existing installations. So we are reverting this patch and the 8 followup patches. What makes this revert easier is that GCC9 will likely include the new 'asm inline' syntax that makes inlining of assembly blocks a lot more robust. This is a superior method to any macro based hackeries - and might even be backported to GCC8, which would make all modern distros get the inlining fixes as well. Many thanks to Masahiro Yamada and others for helping sort out these problems. Reported-by:Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by:
