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.

-config EARLY_PRINTK
-	bool "Early printk" if EMBEDDED && DEBUG_KERNEL
-	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 DEBUG_STACKOVERFLOW
-	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.
-
-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.

-config DEBUG_PAGEALLOC
-	bool "Debug page memory allocations"
-	depends on DEBUG_KERNEL && !HIBERNATION && !HUGETLBFS
-	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 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.
-	  If in doubt, say "N".

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

-          This option allows trapping of rare doublefault exceptions that

-          option saves about 4k and might cause you much additional grey
-          hair.
