This patch series adds knowledge about various memory management structures to the standard print functions. In essence, it allows us to easily print those structures: printk("%pZp %pZm %pZv", page, mm, vma); This allows us to customize output when hitting bugs even further, thus we introduce VM_BUG() which allows printing anything when hitting a bug rather than just a single piece of information. This also means we can get rid of VM_BUG_ON_* since they're now nothing more than a format string.
