"debugfs: add tools to printk 32-bit registers" adds new functions which rely on IOMEM functionality which is not present on all architectures and therefore result in compile errors:
fs/debugfs/file.c: In function 'debugfs_print_regs32': fs/debugfs/file.c:561:7: error: implicit declaration of function 'readl' [-Werror=implicit-function-declaration]
Add an #ifdef CONFIG_HAS_IOMEM to fix this
