2011-01-13um: mark CONFIG_HIGHMEM as brokenRichard Weinberger
Currently CONFIG_HIGHMEM is broken on User Mode Linux. I'm not sure if it worked ever. It doesn't compile and this breaks randomconfig testing.

2010-10-26uml: define CONFIG_NO_DMAFUJITA Tomonori
I think that it's better to detect DMA misuse at build time rather than calling BUG_ON. Architectures that can't do DMA need to define CONFIG_NO_DMA. Thanks to Sam Ravnborg for explaining how CONFIG_NO_DMA and CONFIG_HAS_DMA work: http://marc.info/?l=linux-kernel&m=128359913825550&w=2 HAS_DMA is defined like this: config HAS_DMA boolean depends on !NO_DMA default y So to set HAS_DMA to true an arch should do: 1) Do not define NO_DMA 2) Define NO_DMA abd set it to 'n' Must archs - including um - used principle 1). In the um case we want to say that we do NOT have any DMA. This can be done in two ways. a) define NO_DMA and set it to 'y' b) redefine HAS_DMA and set it to 'n'. The patch you provided used principle b) where other archs use principle a). So I suggest you should use principle a) for um too.

2008-10-23x86, um: get rid of arch/um/Kconfig.archAl Viro
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).
