commit208cbb3255upstream. It was reported that the commitd0a8d9378dis causing users of gcc < 4.9 to observe -Werror=missing-prototypes errors. Indeed, it seems that: extern inline unsigned long native_save_fl(void) { return 0; } compiled with -Werror=missing-prototypes produces this warning in gcc < 4.9, but not gcc >= 4.9. Fixes:d0a8d9378d("x86/paravirt: Make native_save_fl() extern inline").

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.
