This is to replace occurrences of get_allocated_vmalloc_memory(). Splitting into libmeminfo already found a bug with current code which failed to account for memory allocated by modules due to addition of the extra [%module_name%] in __builtin_return_address(). See: https://elixir.bootlin.com/linux/latest/source/kernel/kallsyms.c#L373 Also improves the performance a bit in the process.
