x86, um: get rid of arch/um/Kconfig.arch
Teach scripts/kconfig/Makefile and top-level Makefile that arch/*/Makefile is allowed to say Kconfig := <whatever I want instead of arch/blah/Kconfig>. Rewrite arch/um/Kconfig and arch/um/Kconfig.<subarch> so that the latter would be top-level one (and include the pieces of the former).

- default n
- help
- This option gives you the ability to force a static link of UML.
- Normally, UML is linked as a shared binary. This is inconvenient for
- use in a chroot jail. So, if you intend to run UML inside a chroot,
- you probably want to say Y here.
- Additionally, this option enables using higher memory spaces (up to
- 2.75G) for UML.

-config HOSTFS
- tristate "Host filesystem"
- help
- While the User-Mode Linux port uses its own root file system for
- booting and normal file access, this module lets the UML user
- access files stored on the host. It does not require any
- network connection between the Host and UML. An example use of
- this might be:
-
- mount none /tmp/fromhost -t hostfs -o /tmp/umlshare
-
- where /tmp/fromhost is an empty directory inside UML and
- /tmp/umlshare is a directory on the host with files the UML user
- wishes to access.
-
- For more information, see
- <http://user-mode-linux.sourceforge.net/hostfs.html>.
-
- If you'd like to be able to work with files stored on the host,
- say Y or M here; otherwise say N.
-
-config HPPFS
- tristate "HoneyPot ProcFS (EXPERIMENTAL)"
- depends on EXPERIMENTAL
- help
- hppfs (HoneyPot ProcFS) is a filesystem which allows UML /proc
- entries to be overridden, removed, or fabricated from the host.
- Its purpose is to allow a UML to appear to be a physical machine
- by removing or changing anything in /proc which gives away the
- identity of a UML.
-
- See <http://user-mode-linux.sf.net/old/hppfs.html> for more information.
-
- You only need this if you are setting up a UML honeypot. Otherwise,
- it is safe to say 'N' here.
-
-config MCONSOLE
- bool "Management console"
- default y
- help
- The user mode linux management console is a low-level interface to
- the kernel, somewhat like the i386 SysRq interface. Since there is
- a full-blown operating system running under every user mode linux
- instance, there is much greater flexibility possible than with the
- SysRq mechanism.
-
- If you answer 'Y' to this option, to use this feature, you need the
- mconsole client (called uml_mconsole) which is present in CVS in
- 2.4.5-9um and later (path /tools/mconsole), and is also in the
- distribution RPM package in 2.4.6 and later.
-
- It is safe to say 'Y' here.
-
-config MAGIC_SYSRQ
- bool "Magic SysRq key"
- depends on MCONSOLE
- help
- If you say Y here, you will have some control over the system even
- if the system crashes for example during kernel debugging (e.g., you
- will be able to flush the buffer cache to disk, reboot the system
- immediately or dump some status information). A key for each of the
- possible requests is provided.
-
- This is the feature normally accomplished by pressing a key
- while holding SysRq (Alt+PrintScreen).
-
- On UML, this is accomplished by sending a "sysrq" command with
- mconsole, followed by the letter for the requested command.
-
- The keys are documented in <file:Documentation/sysrq.txt>. Don't say Y
- unless you really know what this hack does.
-
-config SMP
- bool "Symmetric multi-processing support (EXPERIMENTAL)"
- default n
- depends on BROKEN
- help
- This option enables UML SMP support.
- It is NOT related to having a real SMP box. Not directly, at least.
-
- UML implements virtual SMP by allowing as many processes to run
- simultaneously on the host as there are virtual processors configured.
-
- Obviously, if the host is a uniprocessor, those processes will
- timeshare, but, inside UML, will appear to be running simultaneously.
- If the host is a multiprocessor, then UML processes may run
- simultaneously, depending on the host scheduler.
-
- This, however, is supported only in TT mode. So, if you use the SKAS
- patch on your host, switching to TT mode and enabling SMP usually
- gives you worse performances.
- Also, since the support for SMP has been under-developed, there could
- be some bugs being exposed by enabling SMP.
-
- If you don't know what to do, say N.
-
-config NR_CPUS
- int "Maximum number of CPUs (2-32)"
- range 2 32
- depends on SMP
- default "32"
-
-config HIGHMEM
- bool "Highmem support (EXPERIMENTAL)"
- depends on !64BIT && EXPERIMENTAL
- default n
- help
- This was used to allow UML to run with big amounts of memory.
- Currently it is unstable, so if unsure say N.
-
- To use big amounts of memory, it is recommended enable static
- linking (i.e. CONFIG_STATIC_LINK) - this should allow the
- guest to use up to 2.75G of memory.
-
-config KERNEL_STACK_ORDER
- int "Kernel stack size order"
- default 1 if 64BIT
- range 1 10 if 64BIT
- default 0 if !64BIT
- help
- This option determines the size of UML kernel stacks. They will
- be 1 << order pages. The default is OK unless you're running Valgrind
- on UML, in which case, set this to 3.
