This allows mutex semantics violations and mutex related deadlocks
If unsure, say N.
-config DEBUG_IOREMAP
- bool "Enable ioremap() debugging"
- depends on DEBUG_KERNEL && PARISC
- help
- 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.

debugfs is a virtual file system that kernel developers use to put
debugging files into. Enable this option to be able to read and

If you say Y here the resulting kernel image will be slightly larger
but not slower, and it will give very useful debugging information.
