[PATCH] uml: arch Kconfig menu cleanups 



*) mark as "EXPERIMENTAL" various items that either aren't very stable or
   that are actively crashing the setup of users which don't really need them
   (i.e.  HIGHMEM and 3-level pagetables on x86 - nobody needs either,
   everybody reports "I'm using it and getting trouble").

*) move net/Kconfig near to the rest of network configurations, and
   drivers/block/Kconfig near "Block layer" submenu.

*) it's useless and doesn't work well to force NETDEVICES on and to disable
   the prompt like it's done.  Better remove the attempt, and change that to a
   simple "default y if UML".

*) drop the warning about "report problems about HPPFS" - it's redundant
   anyway, as that's the usual procedure, and HPPFS users are especially
   technical (i.e.  they know reporting bugs is _good_).

	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 to disable TT mode (i.e.

	CONFIG_MODE_TT) and enable static linking (i.e. CONFIG_STATIC_LINK) -

	this should allow the guest to use up to 2.75G of memory.
