+Subject: [gcc-14 PATCH] objtool: Fix calloc call for new -Walloc-size
+
+GCC 14 introduces a new -Walloc-size included in -Wextra which errors out
+like:
+```
+check.c: In function ‘cfi_alloc’:
+check.c:294:33: error: allocation of insufficient size ‘1’ for type ‘struct cfi_state’ with size ‘320’ [-Werror=alloc-size]
+  294 |         struct cfi_state *cfi = calloc(sizeof(struct cfi_state), 1);
+      |                                 ^~~~~~
+```
+
+The calloc prototype is:
+```
+void *calloc(size_t nmemb, size_t size);
+```
+
+So, just swap the number of members and size arguments to match the prototype, as
+we're initialising 1 struct of size `sizeof(struct ...)`. GCC then sees we're not
+doing anything wrong.
