-config IA64_PRINT_HAZARDS
- bool "Print possible IA-64 dependency violations to console"
- depends on DEBUG_KERNEL
- help
- Selecting this option prints more information for Illegal Dependency
- Faults, that is, for Read-after-Write (RAW), Write-after-Write (WAW),
- or Write-after-Read (WAR) violations. This option is ignored if you
- are compiling for an Itanium A step processor
- (CONFIG_ITANIUM_ASTEP_SPECIFIC). If you're unsure, select Y.

-config DISABLE_VHPT
- bool "Disable VHPT"
- depends on DEBUG_KERNEL
- help
- The Virtual Hash Page Table (VHPT) enhances virtual address
- translation performance. Normally you want the VHPT active but you
- can select this option to disable the VHPT for debugging. If you're
- unsure, answer N.

-config MAGIC_SYSRQ
- bool "Magic SysRq key"
- depends on DEBUG_KERNEL
- help
- If you say Y here, you will have some control over the system even
- if the system crashes for example during kernel debugging (e.g., you
- will be able to flush the buffer cache to disk, reboot the system
- immediately or dump some status information). This is accomplished
- by pressing various keys while holding SysRq (Alt+PrintScreen). It
- also works on a serial console (on PC hardware at least), if you
- send a BREAK and then within 5 seconds a command keypress. The
- keys are documented in <file:Documentation/sysrq.txt>. Don't say Y
- unless you really know what this hack does.

-config DEBUG_SLAB
- bool "Debug memory allocations"
- depends on DEBUG_KERNEL
- help
- Say Y here to have the kernel do limited verification on memory
- allocation as well as poisoning memory on free to catch use of freed
- memory.
