[$] Kernel optimization with BOLT

A pair of talks in the toolchainstrack at the 2024 LinuxPlumbers Conference covered different tools that can be used tooptimize the kernel. First up was Maksim Panchenko to describe the binaryoptimization and layout tool (BOLT) that Meta uses on its productionkernels. It optimizes the kernel binary by rearranging it to improve itscode locality forbetter performance. A subsequent article will cover the second talk, whichlooked at automaticfeedback-directed optimization (AutoFDO) and other related techniquesthat are used to optimize Google's kernels.
