x86: unification of i386 and x86_64 Kconfig.debug
Adding proper dependencies so the two Kconfig.debug files are now identical and move the result file to x86. Signed-off-by: Randy Dunlap <randy.dunlap@oracle.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

- bool "Write protect kernel read-only data structures"
- depends on DEBUG_KERNEL
- help
- Mark the kernel read-only data as write-protected in the pagetables,
- in order to catch accidental (and incorrect) writes to such const data.
- This option may have a slight performance impact because a portion
- of the kernel code won't be covered by a 2MB TLB anymore.
- If in doubt, say "N".
- depends on IOMMU && DEBUG_KERNEL
- bool "Enable IOMMU debugging"
- help
- Force the IOMMU to on even when you have less than 4GB of
- memory and add debugging code. On overflow always panic. And
- allow to enable IOMMU leak tracing. Can be disabled at boot
- time with iommu=noforce. This will also enable scatter gather
- list merging. Currently not recommended for production
- code. When you use it make sure you have a big enough
- IOMMU/AGP aperture. Most of the options enabled by this can
- be set more finegrained using the iommu= command line
- options. See Documentation/x86_64/boot-options.txt for more
- details.

- bool "IOMMU leak tracing"

- depends on IOMMU_DEBUG
- help
- Add a simple leak tracer to the IOMMU code. This is useful when you
- are debugging a buggy device driver that leaks IOMMU mappings.
- bool "Check for stack overflows"
- depends on DEBUG_KERNEL
- help
- This option will cause messages to be printed if free stack space
- drops below a certain limit.
- bool "Stack utilization instrumentation"
- depends on DEBUG_KERNEL
- help
- Enables the display of the minimum amount of free stack which each
- task has ever had available in the sysrq-T and sysrq-P debug output.
- This option will slow down process creation somewhat.
