"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.Signed-off-by: Josh Triplett

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"

When searching for symbols, return the symbols sorted by relevance.
Sorting is done as thus:
- first, symbols that match exactly
- then, alphabetical sortSince 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.

Currently the odds to set each symbol is (rounded):
booleans: y: 50% n: 50%
tristates: y: 33% m: 33% n: 33%Introduce a KCONFIG_PROBABILITY environment variable to tweak the
probabilities (in percentage), as such:
KCONFIG_PROBABILITY y:n split y:m:n split
-----------------------------------------------------------------
[1] unset or empty 50 : 50 33 : 33 : 34
[2] N N : 100-N N/2 : N/2 : 100-N
N:M N+M : 100-(N+M) N : M : 100-(N+M)
N:M:L N : 100-N M : L : 100-(M+L)[1] The current behaviour is kept as default, for backward compatibility

For reproducibility, it can be useful to be able to specify the
seed to use to seed the RNG.Add a new KCONFIG_SEED environment variable which can be set to
the seed to use:
$ make KCONFIG_SEED=42 randconfig
$ sha1sum .config
70a128c8dcc61303069e1be352cce64114dfcbca .config
$ make KCONFIG_SEED=42 randconfig
$ sha1sum .config
70a128c8dcc61303069e1be352cce64114dfcbca .configIt's very usefull for eg. debugging the kconfig parser.

The kbuild's ld-option function is broken because
the command
$(CC) /dev/null -c -o "$$TMPO"
does not create object file!I have used a relatively old mips gcc 3.4.6 cross-compiler
and a relatively new gcc 4.7.2 to check this fact
but the results are the same.EXAMPLE:
$ rm /tmp/1.o
$ mips-linux-gcc /dev/null -c -o /tmp/1.o
mips-linux-gcc: /dev/null: linker input file unused because linking not done
$ ls -la /tmp/1.o
ls: cannot access /tmp/1.o: No such file or directoryWe can easily fix the problem by adding
the '-x c' compiler option.EXAMPLE:
$ rm /tmp/1.o
$ mips-linux-gcc -x c /dev/null -c -o /tmp/1.o
$ ls -la /tmp/1.o

All architectures that use cmd_dtc do so in almost the same way. Create
a central build rule to avoid duplication. The one difference is that
most current uses of dtc build $(obj)/%.dtb from $(src)/dts/%.dts rather
than building the .dtb in the same directory as the .dts file. This
difference will be eliminated arch-by-arch in future patches.MIPS is the exception here; it already uses the exact same rule as the
new common rule, so the duplicate is removed in this patch to avoid any
conflict. arch/mips changes courtesy of Ralf Baechle.Update Documentation/kbuild to remove the explicit call to cmd_dtc from
the example, now that the rule exists in a centralized location.Cc: Arnd Bergmann
