Hi all,

After merging the akpm-current tree, today's linux-next build (x86_64
allmodconfig) failed like this:

init/main.c: In function 'xbc_make_cmdline':
init/main.c:384:3: error: implicit declaration of function 'memblock_free_ptr'; did you mean 'memblock_free_late'? [-Werror=implicit-function-declaration]
  384 |   memblock_free_ptr(new_cmdline, len + 1);
      |   ^~~~~~~~~~~~~~~~~
      |   memblock_free_late
cc1: all warnings being treated as errors

Caused by commit

  d6e96e5e2e23 ("memblock: use memblock_free for freeing virtual pointers")

interacting with commit

  1ae43851b18a ("bootconfig: init: Fix memblock leak in xbc_make_cmdline()")

from Linus' tree.

I have applied the following merge fix patch.
