Kconfig recognizes the end of help text by receding indentation depth. Recent patch had broken HOST_VMSPLIT_... choice in arch/um/Kconfig.i386 - all alternatives are interpreted as part of help text now.

default HOST_VMSPLIT_3G
|

help
|
|
This is needed when the host kernel on which you run has a non-default
|
|
(like 2G/2G) memory split, instead of the customary 3G/1G. If you did
|
|
not recompile your own kernel but use the default distro's one, you can
|
|
safely accept the "Default split" option.
|
|
|
|
It can be enabled on recent (>=2.6.16-rc2) vanilla kernels via
|
|
CONFIG_VM_SPLIT_*, or on previous kernels with special patches (-ck
|
|
patchset by Con Kolivas, or other ones) - option names match closely the
|
|
host CONFIG_VM_SPLIT_* ones.
|
|
|
|
A lower setting (where 1G/3G is lowest and 3G/1G is higher) will
|
|
tolerate even more "normal" host kernels, but an higher setting will be
|
|
stricter.
|
|
|
|
So, if you do not know what to do here, say 'Default split'.

|
Three-level pagetables will let UML have more than 4G of physical
|
|
memory. All the memory that can't be mapped directly will be treated
|
|
as high memory.
|
|
|
|
However, this it experimental on 32-bit architectures, so if unsure say
|
|
N (on x86-64 it's automatically enabled, instead, as it's safe there).
