kbuild: use getopt_long(), not its _only() variant

2010-12-09T21:33:30+00:00

commit c94d3fb01fb6db1899cdf53ea4eb9d38e08a08fe upstream.

NetBSD lacks getopt_long_only() whereas getopt_long() works just fine.

kbuild: fix oldnoconfig to do the right thing

2010-10-09T21:55:08+00:00

Commit 861b4ea4 broke oldnoconfig when removed the oldnoconfig checks on
                       if (input_mode == nonint_oldconfig ||
                           input_mode == oldnoconfig) {
                               if (input_mode == nonint_oldconfig &&
                                   sym->name &&
                                    !sym_is_choice_value(sym)) {
to avoid oldnoconfig chugging through the else stanza.

Fix that to restore expected behaviour (which I've confirmed in the
Fedora kernel build that the configs end up looking the same.)

kconfig: Temporarily disable dependency warnings

2010-10-09T21:19:07+00:00

After fixing a use-after-free bug in kconfig, a 'make defconfig' or
'make allmodconfig' fills the screen with warnings that were not
detected before. Given that we are close to the release now, disable the
warnings temporarily and deal with them after 2.6.36.

kconfig: fix segfault when detecting recursive dependency

2010-08-14T22:32:13+00:00

Following sample Kconfig generated a segfault:

config FOO
        bool
        select PERF_EVENTS if HAVE_HW_BREAKPOINT

config PERF_EVENTS
        bool

config HAVE_HW_BREAKPOINT
        bool
        depends on PERF_EVENTS

Fix by reverting back to a valid property if there was no
property on the stack of symbols.

The above pattern were seen in sh Kconfig.
A fix for the Kconfig file has been sent to the sh folks.

kconfig: fix savedefconfig with choice marked optional

2010-08-14T22:32:12+00:00

savedefconfig failed to save the correct minimal config
when it encountered a choice marked optional.

Consider following minimal configuration:
$cat Kconfig
choice
	prompt "choice"
	optional

config A
	bool "a"

config B
	bool "b"

endchoice

$cat .config | grep -v ^#
CONFIG_A=y

$conf --savedefconfig=defconfig Kconfig

would before this fix result in an empty file, because
kconfig would assume that CONFIG_A=y is a default value.
But because the choice is optional the default is that
both A and B are =n.

Fix so we handle optional choices correct.
