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.

If you say Y here the resulting kernel image will be slightly larger
but not slower, and it will give very useful debugging information.
If you don't debug the kernel, you can say N, but we may not be able
to solve problems without frame unwind information or frame pointers.
