Entry now reads: IA64 compare-and-exchange bug checking CONFIG_IA64_DEBUG_CMPXCHG Selecting this option turns on bug checking for the IA64 compare-and-exchange instructions. This is slow!

Entry now reads: IA64 IRQ bug checking CONFIG_IA64_DEBUG_IRQ Selecting this option turns on bug checking for the IA64 irq_save and restore instructions. It's useful for tracking down spinlock problems, but slow! If you're unsure, select N. -- Eric S. Raymond In recent years it has been suggested that the Second Amendment protects the "collective" right of states to maintain militias, while it does not protect the right of "the people" to keep and bear arms.
