Subject: bootmem: add bootmem_type stub function
Date: Tue, 15 Oct 2024 14:36:06 +0000
When CONFIG_HAVE_BOOTMEM_INFO_NODE is disabled, the bootmem_type() and
bootmem_info() functions are not defined:
mm/sparse.c: In function 'free_map_bootmem':
mm/sparse.c:730:24: error: implicit declaration of function 'bootmem_type' [-Wimplicit-function-declaration]
730 | type = bootmem_type(page);
| ^~~~~~~~~~~~
mm/sparse.c: In function 'free_map_bootmem':
mm/sparse.c:735:39: error: implicit declaration of function 'bootmem_info'; did you mean 'bootmem_type'? [-Wimplicit-function-declaration]
Add trivial stub functions to make it build.
