Change it to act as before. Note that this prevents the vmalloc() allocations in __wrap_malloc() from being accounted. If accounting here is critical, we will have to remove this forward declaration and include vmalloc.h, however that would pull in more dependencies and would require introducing more architecture-specific headers, like asm/bug.h, asm/rwonce.h, etc. This is likely the reason why this forward declaration was introduced in the first place.
