This patch can likely be taken regardless of the rest of the series. It would be good to get additional review from the person who added CONFIG_LD_DEAD_CODE_DATA_ELIMINATION maybe? On Fri, Nov 3, 2017 at 10:11 AM, Sami Tolvanen [off-list ref] wrote:

Make sure the linker doesn't remove .altinstructions or .altinstr_replacement when CONFIG_LD_DEAD_CODE_DATA_ELIMINATION is enabled.
