* kconfig: make allnoconfig disable options behind EMBEDDED and EXPERTJosh Triplett2014-04-081-0/+4
| | | | | | | | | | | | | | | | | | | | | | | "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'Yann E. MORIN2013-09-051-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | 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 Signed-off-by: "Yann E.

* Revert "kconfig-language: add to hints"Yann E. MORIN2012-12-061-23/+0Star
| | | | | | | | | | | | | | | | This reverts commit 64b81ed7fb1e45c914317b20316f32827bc6444b. As Martin says about this paragraph: However, I can not reproduce this. The attached file contains both cases. [...] AFAICS, both versions behave equivalently. I suggest changing the documentation accordingly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Changeset 5a1aa8a1 added the possibility to name a choice, and to have the same choice be defined multiple times. But the documentation was forgotten, so this updates it accordingly.

* kconfig: implement the `mainmenu' directiveArnaud Lacombe2010-09-201-1/+2
| | | | | | | | | | | | If specified, the directive must be placed at the top of the Kconfig file. We need to change the grammar to make the mainmenu directive set the `rootmenu' prompt. This reflect how menu_add_prompt() works internally, ie. set the prompt of the `current_entry', pointing originally to `rootmenu'.

* Linux-2.6.12-rc2Linus Torvalds2005-04-171-0/+282
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
