Merge tag 'bootconfig-v7.4' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-traceHEADmaster

Pull bootconfig updates from Masami Hiramatsu:
 "Parser robustness and validation improvements:

   - Skip printing early params to cmdline from bootconfig

     Suppress early_param keys from /proc/cmdline and warn the user,
     since bootconfig does not invoke early_param handlers and silently
     ignoring them is misleading

   - Reject unexpected data after null character

     Detect and reject non-null data following an intermediate null
     character in the bootconfig buffer, preventing silently ignored
     configuration after an early termination

  Code cleanups:

   - Merge _xbc_exit() into xbc_exit()

     Since memblock_free() now handles late freeing and NULL addresses,
     the separate _xbc_exit() helper and its early argument are
     unnecessary. Inline it into xbc_exit()

   - Remove redundant assignment in xbc_parse_array()

     The node->child = 0 assignment after the loop duplicates what
     xbc_init_node() already did

   - Skip internal tree sanity checks in kernel

     Move the node index bounds loop from xbc_verify_tree() into a
     userspace-only xbc_sanity_check_tree() to reduce boot-time
     overhead, since out-of-bounds indices cannot be produced by
     malformed input

   - Move BOOTCONFIG_FOOTER_SIZE to include/linux/bootconfig.h

     Share the footer size constant between kernel and user-space tools,
     replacing the hardcoded (BOOTCONFIG_MAGIC_LEN + 8) expression in
     init/main.c

  Tooling improvements:

   - Remove unused PAGE_SIZE macro from the bootconfig tool

   - Consolidate xbc_init() to error message wrapper

     Use init_xbc_with_error() for all bootconfig initialization paths
     in the tool for simpler and more consistent error handling"
