[Test Plan] * Check symbols on running kernel sudo grep -e ' ref_module' -e ' find_symbol' -e ' each_symbol_section$' -e ' __module_address' -e ' __module_text_address' /proc/kallsyms * Check symbols on all installed kernels sudo grep -e ' ref_module' -e ' find_symbol' -e ' each_symbol_section$' -e ' __module_address' -e ' __module_text_address' /boot/System.map-* [Where problems could occur] * The new functionality provided by patches will be removed, since we aren't removing existing functionality the risk should be low.
