  • 94295e230   um: mark CONFIG_HIGHMEM as broken ... Browse Code »

    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.

  • d911202e3   uml: define CONFIG_NO_DMA ... Browse Code »

    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.

    Teach scripts/kconfig/Makefile and top-level Makefile that arch/*/Makefile
    is allowed to say Kconfig := .
    Rewrite arch/um/Kconfig and arch/um/Kconfig. so that the latter
    would be top-level one (and include the pieces of the former).
