Merge tag 'bootconfig-v7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace

Pull bootconfig updates from Masami Hiramatsu:

 - bootconfig: move xbc_snprint_cmdline() to lib/bootconfig.c

   Move the xbc_snprint_cmdline() function and its buffer from
   main.c to the shared lib/bootconfig.c parser library so it
   can be reused by userspace tools.

 - render kernel.* subtree as cmdline string with -C

   Add a new -C option to print the kernel.* subtree as a flat
   command-line string at build time, allowing early parameter
   injection without runtime parsing.
