+# X86
+config EARLY_PRINTK
+       bool "Early printk" if EMBEDDED && DEBUG_KERNEL
+       default y
+       depends on X86
+       help
+         Write kernel log output directly into the VGA buffer or to a serial
+         port.
+
+         This is useful for kernel debugging when your machine crashes very
+         early before the console code is initialized. For normal operation
+         it is not recommended because it looks ugly and doesn't cooperate
+         with klogd/syslogd or the X server. You should normally N here,
+         unless you want to debug such a crash.
+
+config DEBUG_STACKOVERFLOW
+       bool "Check for stack overflows"
+       depends on DEBUG_KERNEL && X86
+
+config KPROBES
+       bool "Kprobes"
+       depends on DEBUG_KERNEL && X86
+       help
+         Kprobes allows you to trap at almost any kernel address and
+         execute a callback function.  register_kprobe() establishes
+         a probepoint and specifies the callback.  Kprobes is useful
+         for kernel debugging, non-intrusive instrumentation and testing.
+         If in doubt, say "N".
+
+config DEBUG_STACK_USAGE
+       bool "Stack utilization instrumentation"
+       depends on DEBUG_KERNEL && X86
+       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.
+
+comment "Page alloc debug is incompatible with Software Suspend on i386"
+       depends on DEBUG_KERNEL && SOFTWARE_SUSPEND && X86
+
+config DEBUG_PAGEALLOC
+       bool "Page alloc debugging"
+       depends on DEBUG_KERNEL && !SOFTWARE_SUSPEND && X86
+       help
+         Unmap pages from the kernel linear mapping after free_pages().
+         This results in a large slowdown, but helps to find certain types
+         of memory corruptions.
+
+config 4KSTACKS
+       bool "Use 4Kb for kernel stacks instead of 8Kb"
+       depends on DEBUG_KERNEL && X86
+       help
+         If you say Y here the kernel will use a 4Kb stacksize for the
+         kernel stack attached to each process/thread. This facilitates
+         running more threads on a system and also reduces the pressure
+         on the VM subsystem for higher order allocations. This option
+         will also use IRQ stacks to compensate for the reduced stackspace.
+
+config X86_FIND_SMP_CONFIG
+       bool
+       depends on X86_LOCAL_APIC || X86_VOYAGER && X86
+       default y
+
+config X86_MPPARSE

+       depends on X86_LOCAL_APIC && !X86_VISWS && X86
+       default y
+
+# X86_64
+
+# !SMP for now because the context switch early causes GPF in segment reloading
+# and the GS base checking does the wrong thing then, causing a hang.
+config CHECKING
+       bool "Additional run-time checks"
+       depends on DEBUG_KERNEL && !SMP && X86_64
+       help
+         Enables some internal consistency checks for kernel debugging.
+         You should normally say N.
+
+config INIT_DEBUG
+       bool "Debug __init statements"
+       depends on DEBUG_KERNEL && X86_64
+       help
+         Fill __init and __initdata at the end of boot. This helps debugging
+         illegal uses of __init and __initdata after initialization.
+
+config IOMMU_DEBUG
+       depends on GART_IOMMU && DEBUG_KERNEL && X86_64
+       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.
+
+config IOMMU_LEAK
+       bool "IOMMU leak tracing"
+       depends on DEBUG_KERNEL && X86_64
+       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.
+
+#config X86_REMOTE_DEBUG
+#       bool "kgdb debugging stub"
+
+# X86 & X86_64
+config KPROBES

+       help
+         Kprobes allows you to trap at almost any kernel address and
+         execute a callback function.  register_kprobe() establishes
