In clock sched we now have three loads: - Function pointer - quotient for multiplication - offset However, it is possible to improve performance substantially, by guaranteeing that all three loads are from the same cacheline. By moving these three values first in sparc64_tick_ops, and by having tick_operations 64-byte aligned we guarantee this.

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.
