CONFIG_DEBUG_IOREMAP: Enable ioremap() debugging

General informations

The Linux kernel configuration item CONFIG_DEBUG_IOREMAP:

• prompt: Enable ioremap() debugging
• type: bool
• depends on: CONFIG_DEBUG_KERNEL && CONFIG_PARISC
• defined in lib/Kconfig.debug
• found in Linux kernels: 2.6.11–2.6.16

Help text

Enabling this option will cause the kernel to distinguish between ioremapped and physical addresses. It will print a backtrace (at most one every 10 seconds), hopefully allowing you to see which drivers need work. Fixing all these problems is a prerequisite for turning on USE_HPPA_IOREMAP. The warnings are harmless; the kernel has enough information to fix the broken drivers automatically, but we'd like to make it more efficient by not having to do that.
