kconfig: make allnoconfig disable options behind EMBEDDED and EXPERT

2014-04-07T23:36:09+00:00

"make allnoconfig" exists to ease testing of minimal configurations.
Documentation/SubmitChecklist includes a note to test with allnoconfig.
This helps catch missing dependencies on common-but-not-required
functionality, which might otherwise go unnoticed.

However, allnoconfig still leaves many symbols enabled, because they're
hidden behind CONFIG_EMBEDDED or CONFIG_EXPERT.  For instance, allnoconfig
still has CONFIG_PRINTK and CONFIG_BLOCK enabled, so drivers don't
typically get build-tested with those disabled.

To address this, introduce a new Kconfig option "allnoconfig_y", used on
symbols which only exist to hide other symbols.  Set it on CONFIG_EMBEDDED
(which then selects CONFIG_EXPERT).  allnoconfig will then disable all the
symbols hidden behind those.

kconfig: do not allow more than one symbol to have 'option modules'

2013-09-05T09:10:08+00:00

Previously, it was possible to have more than one symbol with the
'option modules' attached to them, although only the last one would
in fact control tristates.

Since this does not make much sense, only allow at most one symbol to
control tristates.

Note: it is still possible to have more than one symbol that control
tristates, but indirectly:

    config MOD1
        bool "mod1"
        select MODULES
    config MOD2
        bool "mod2"
        select MODULES
    config MODULES
        bool
        option modules

Documentation/kconfig: more concise and straightforward search explanation

2013-07-16T18:26:30+00:00

Re-phrase the explanations on the sorting of search results, in a more
concise and complete way.

Drop reference to the user's locale when sorting alphabetically, since
this is implicit.

kconfig: sort found symbols by relevance

2013-06-24T17:57:45+00:00

When searching for symbols, return the symbols sorted by relevance.

Sorting is done as thus:
  - first, symbols that match exactly
  - then, alphabetical sort

Since the search can be a regexp, it is possible that more than one symbol
matches exactly. In this case, we can't decide which to sort first, so we
fallback to alphabeticall sort.

Explain this (new!) sorting heuristic in the documentation.

Changes v1->v2:
  - drop the previous, complex heuristic in favour of a simpler heuristic
    that is both easier to understand, *and* to maintain (Jean)
  - explain sorting heuristic in the doc  (Jean)

Finally eradicate CONFIG_HOTPLUG

2013-06-03T21:20:18+00:00

Ever since commit 45f035ab9b8f ("CONFIG_HOTPLUG should be always on"),
it has been basically impossible to build a kernel with CONFIG_HOTPLUG
turned off.  Remove all the remaining references to it.
