If a minimal config did not specify the value
of all choice values, the resulting configuration
could have wrong values.Consider following example:
config M
def_bool y
option modules
choice
prompt "choice list"
config A
tristate "a"
config B
tristate "b"
endchoiceWith a defconfig like this:
CONFIG_M=y
CONFIG_A=yThe resulting configuration would have
CONFIG_A=m
which was unexpected.
The problem was not not all choice values were set and thus
kconfig calculated a wrong value.The fix is to set all choice values when we
read a defconfig files.conf_set_all_new_symbols() is refactored such that
random choice values are now handled by a dedicated function.
And new choice values are set by set_all_choice_values().This was not the minimal fix, but the fix that resulted
in the most readable code.Signed-off-by: Sam Ravnborg

These are caused by checkpatch incorrectly parsing its internal
representation of a statement block for struct's (or anything else that is
a statement block encapsulated in {}'s that also ends with a ';'). Fix
this by properly parsing a statement block.An example:
+struct dummy_type dummy = {
+ .foo = "baz",
+};
+EXPORT_SYMBOL_GPL(dummy);
+
+static int dummy_func(void)
+{
+ return -EDUMMYCODE;
+}
+EXPORT_SYMBOL_GPL(dummy_func);WARNING: EXPORT_SYMBOL(foo); should immediately \
follow its function/variable
#19: FILE: dummy.c:4:
+EXPORT_SYMBOL_GPL(dummy);The above warning is issued when it should not be.

thing is totally buggy, and doesn't just change the option names, but
actively breaks them.The old behaviour (from years ago) were reintroduced by accident. Fix

savedefconfig will save a minimal config to a file
named "defconfig".The config symbols are saved in the same order as
they appear in the menu structure so it should
be possible to map them to the relevant menus
if desired.The implementation was tested against several minimal
configs for arm which was created using brute-force.There was one regression related to default numbers
which had their valid range further limited by another symbol.Sample:
config FOO
int "foo"
default 4config BAR
int "bar"
range 0 FOOIf FOO is set to 3 then BAR cannot take a value higher than 3.
But the current implementation will set BAR equal to 4.This is seldomly used and the final configuration is OK,
and the fix was non-trivial.
So it was documented in the code and left as is.Signed-off-by: Sam Ravnborg

Consider following kconfig file:
config TEST1
bool "test 1"
depends on TEST2config TEST2
bool "test 2"
depends on TEST1Previously kconfig would report:
foo:6:error: found recursive dependency: TEST2 -> TEST1 -> TEST2
With the following patch kconfig reports:
foo:5:error: recursive dependency detected!
foo:5: symbol TEST2 depends on TEST1
foo:1: symbol TEST1 depends on TEST2Note that we now report where the offending symbols are defined.
This can be a great help for complex situations involving
several files.Patch is originally from Roman Zippel with a few adjustments by Sam.
