hrtimer_force_reprogram() needs to be available unconditionally for softirq based hrtimers. Move the function and all required struct members out of the CONFIG_HIGH_RES_TIMERS #ifdef. There is no functional change because hrtimer_force_reprogram() is only invoked when hrtimer_cpu_base.hres_active is true and CONFIG_HIGH_RES_TIMERS=y. Making it unconditional increases the text size for the CONFIG_HIGH_RES_TIMERS=n case slightly, but avoids replication of that code for the upcoming softirq based hrtimers support. Most of the code gets eliminated in the CONFIG_HIGH_RES_TIMERS=n case by the compiler.

README
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.
