We can just move the function inside an existing ifdef block.

That file takes a rather unpleasing approach to this problem. Things like
static void unroll_tree_refs(struct audit_context *ctx, struct audit_tree_refs *p, int count) { #ifdef CONFIG_AUDIT_TREE struct audit_tree_refs *q; int n; if (!p) { /* we started with empty chain */ p = ctx->first_trees; count = 31; /* if the very first allocation has failed, nothing to do */ if (!p) return; } n = count; for (q = p; q != ctx->trees; q = q->next, n = 31) { while (n--) { audit_put_chunk(q->c[n]); q->c[n] = NULL; } } while (n-- > ctx->tree_count) { audit_put_chunk(q->c[n]); q->c[n] = NULL; } ctx->trees = p; ctx->tree_count = count; #endif } all over the place. It needs help.
