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.

- Write kernel log output directly into the VGA buffer or to a serial

-
- 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.

- of memory corruptions.

- 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.

- 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.

- 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"

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