The original directory structure was scattered and unorganized.
Changes are basically to make it look like kernel structure.

+
+source "lib/Kconfig.debug"
+
+config STRICT_DEVMEM
+	bool "Filter access to /dev/mem"
+	---help---
+	  If this option is disabled, you allow userspace (root) access to all
+	  of memory, including kernel and userspace memory. Accidental
+	  access to this is obviously disastrous, but specific access can
+	  be used by people debugging the kernel. Note that with PAT support
+	  enabled, even in this case there are restrictions on /dev/mem
+	  use due to the cache aliasing requirements.
+
+	  If this option is switched on, the /dev/mem file only allows
+	  userspace access to PCI space and the BIOS code and data regions.
+	  This is sufficient for dosemu and X and all common users of
+	  /dev/mem.
+
+	  If in doubt, say Y.
+
+config X86_VERBOSE_BOOTUP
+	bool "Enable verbose x86 bootup info messages"
+	default y
+	---help---
+	  Enables the informational output from the decompression stage
+	  (e.g. bzImage) of the boot. If you disable this you will still
+	  see errors. Disable this if you want silent bootup.
+
+config EARLY_PRINTK
+	bool "Early printk" if EXPERT
+	default y
+	---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 EARLY_PRINTK_INTEL_MID
+	bool "Early printk for Intel MID platform support"
+	depends on EARLY_PRINTK && X86_INTEL_MID
+
+config EARLY_PRINTK_DBGP
+	bool "Early printk via EHCI debug port"
+	depends on EARLY_PRINTK && PCI
+	---help---
+	  Write kernel log output directly into the EHCI debug 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. You need usb debug device.
+
+config DEBUG_STACKOVERFLOW
+	bool "Check for stack overflows"
+	depends on DEBUG_KERNEL
+	---help---
+	  Say Y here if you want to check the overflows of kernel, IRQ
+	  and exception stacks. This option will cause messages of the
+	  stacks in detail when free stack space drops below a certain
+	  limit.
+	  If in doubt, say "N".
+
+config X86_PTDUMP
+	bool "Export kernel pagetable layout to userspace via debugfs"
+	depends on DEBUG_KERNEL
+	select DEBUG_FS
+	---help---
+	  Say Y here if you want to show the kernel pagetable layout in a
+	  debugfs file. This information is only useful for kernel developers
+	  who are working in architecture specific areas of the kernel.
+	  It is probably not a good idea to enable this feature in a production
+	  kernel.
+	  If in doubt, say "N"
+
+config DEBUG_RODATA
+	bool "Write protect kernel read-only data structures"
+	default y
+	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 is recommended so that we can catch kernel bugs sooner.
+	  If in doubt, say "Y".
+
+config DEBUG_RODATA_TEST
+	bool "Testcase for the DEBUG_RODATA feature"
+	depends on DEBUG_RODATA
+	default y
+	---help---
+	  This option enables a testcase for the DEBUG_RODATA
+	  feature as well as for the change_page_attr() infrastructure.
+	  If in doubt, say "N"
+
+config DEBUG_SET_MODULE_RONX
+	bool "Set loadable kernel module data as NX and text as RO"
+	depends on MODULES
+	---help---
+	  This option helps catch unintended modifications to loadable
+	  kernel module's text and read-only data. It also prevents execution
+	  of module data. Such protection may interfere with run-time code
+	  patching and dynamic kernel tracing - and they might also protect
+	  against certain classes of kernel exploits.
+	  If in doubt, say "N".
+
+config DEBUG_NX_TEST
+	tristate "Testcase for the NX non-executable stack feature"
+	depends on DEBUG_KERNEL && m
+	---help---
+	  This option enables a testcase for the CPU NX capability
+	  and the software setup of this feature.
+	  If in doubt, say "N"
+
+config DOUBLEFAULT
+	default y
+	bool "Enable doublefault exception handler" if EXPERT
+	depends on X86_32
+	---help---
+	  This option allows trapping of rare doublefault exceptions that
+	  would otherwise cause a system to silently reboot. Disabling this
+	  option saves about 4k and might cause you much additional grey
+	  hair.
+
+config IOMMU_DEBUG
+	bool "Enable IOMMU debugging"
+	depends on GART_IOMMU && DEBUG_KERNEL
+	depends on X86_64
+	---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/x86_64/boot-options.txt for more
+	  details.
+
+config IOMMU_STRESS
+	bool "Enable IOMMU stress-test mode"
+	---help---
+	  This option disables various optimizations in IOMMU related
+	  code to do real stress testing of the IOMMU code. This option
+	  will cause a performance drop and should only be enabled for
+	  testing.
+
+config IOMMU_LEAK
+	bool "IOMMU leak tracing"
+	depends on IOMMU_DEBUG && DMA_API_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 HAVE_MMIOTRACE_SUPPORT
+	def_bool y
+
+config X86_DECODER_SELFTEST
+	bool "x86 instruction decoder selftest"
+	depends on DEBUG_KERNEL && KPROBES
+	---help---
+	 Perform x86 instruction decoder selftests at build time.
+	 This option is useful for checking the sanity of x86 instruction
+	 decoder code.
+	 If unsure, say "N".

+config IO_DELAY_0X80
+	bool "port 0x80 based port-IO delay [recommended]"
+	---help---
+	  This is the traditional Linux IO delay used for in/out_p.
+	  It is the most tested hence safest selection here.
+
+config IO_DELAY_0XED
+	bool "port 0xed based port-IO delay"
+	---help---
+	  Use port 0xed as the IO delay. This frees up port 0x80 which is
+	  often used as a hardware-debug port.
+
+config IO_DELAY_UDELAY
+	bool "udelay based port-IO delay"
+	---help---
+	  Use udelay(2) as the IO delay method. This provides the delay
+	  while not having any side-effect on the IO port space.
+
+config IO_DELAY_NONE
+	bool "no port-IO delay"
+	---help---
+	  No port-IO delay. Will break on old boxes that require port-IO
+	  delay for certain operations. Should work on most new machines.

+	---help---
+	  This option will cause struct boot_params to be exported via debugfs.
+
+config CPA_DEBUG
+	bool "CPA self-test code"
+	depends on DEBUG_KERNEL
+	---help---
+	  Do change_page_attr() self-tests every 30 seconds.
+
+config OPTIMIZE_INLINING
+	bool "Allow gcc to uninline functions marked 'inline'"
+	---help---
+	  This option determines if the kernel forces gcc to inline the functions
+	  developers have marked 'inline'. Doing so takes away freedom from gcc to
+	  do what it thinks is best, which is desirable for the gcc 3.x series of
+	  compilers. The gcc 4.x series have a rewritten inlining algorithm and
+	  enabling this option will generate a smaller kernel there. Hopefully
+	  this algorithm is so good that allowing gcc 4.x and above to make the
+	  decision will become the default in the future. Until then this option
+	  is there to test gcc for this.
+
+	  If unsure, say N.
+
+config DEBUG_STRICT_USER_COPY_CHECKS
+	bool "Strict copy size checks"
+	depends on DEBUG_KERNEL && !TRACE_BRANCH_PROFILING
+	---help---
+	  Enabling this option turns a certain set of sanity checks for user
+	  copy operations into compile time failures.
+
+	  The copy_from_user() etc checks are there to help test if there
+	  are sufficient security checks on the length argument of
+	  the copy operation, by having gcc prove that the argument is
+	  within bounds.
+
+	  If unsure, or if you run an older (pre 4.4) gcc, say N.
+
+config DEBUG_NMI_SELFTEST
+	bool "NMI Selftest"
+	depends on DEBUG_KERNEL && X86_LOCAL_APIC
+	---help---
+	  Enabling this option turns on a quick NMI selftest to verify
+	  that the NMI behaves correctly.
+
+	  This might help diagnose strange hangs that rely on NMI to
+	  function properly.
+
+	  If unsure, say N.
