Modify the TEO governor to take possible negative return values of tick_nohz_get_next_hrtimer() into account by changing the data type of some variables used by it to s64 which allows it to carry out computations without potentially problematic data type conversions into u64. Also change the computations in teo_select() so that the negative values themselves are handled in a natural way to avoid adding extra negative value checks to that function. Signed-off-by: Rafael J.

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.
