Pull bootconfig updates from Masami Hiramatsu: - Fix ftrace2bconf.sh tool for checking event enable status correctly - Add CONFIG_BOOT_CONFIG_FORCE to apply bootconfig without 'bootconfig' boot parameter - Enable CONFIG_BOOT_CONFIG_FORCE by default if a bootconfig is embedded in the kernel - Increase max number of nodes of bootconfig to 8192 * tag 'bootconfig-v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: bootconfig: Increase max nodes of bootconfig from 1024 to 8192 for DCC support bootconfig: Default BOOT_CONFIG_FORCE to y if BOOT_CONFIG_EMBED Allow forcing unconditional bootconfig processing tools/bootconfig: fix single & used for logical condition
