Subject: [PATCH] x86: move i386 and x86_64 Kconfig files to x86 directory

After a small change in kconfig Makefile we could
move all x86 Kconfig files to x86 directory.

-	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_STACK_USAGE
-	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.

-	  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 DEBUG_RODATA
-	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.

-	bool "Use 4Kb for kernel stacks instead of 8Kb"
-	depends on DEBUG_KERNEL
-	depends on X86_32
-	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.

-	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"

-	  Add a simple leak tracer to the IOMMU code. This is useful when you
-	  are debugging a buggy device driver that leaks IOMMU mappings.
