Messages in this thread Patch in this message | | | From | Guenter Roeck <> | Subject | [PATCH] powerpc/prom_init: Add memset as valid external symbol if CONFIG_KASAN=y | Date | Sat, 18 Jun 2022 20:52:46 -0700 |

If CONFIG_KASAN=y, powerpc:allmodconfig fails to build with the following error.
Error: External symbol 'memset' referenced from prom_init.c
The problem was introduced with commit 41b7a347bf14 ("powerpc: Book3S 64-bit outline-only KASAN support"). So far, with CONFIG_KASAN=y, only __memset was accepted as valid external symbol in prom_init_check.sh. Add memset as well to fix the problem.
