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.
