x86: defconfig not being applied automatically in 2.6.24+
In 2.6.23, if you unpacked a kernel source tarball and then ran "make
menuconfig" you'd be presented with this message:
# using defaults found in arch/i386/defconfig
and the default options would be set.
The same thing in 2.6.24 does not give you any "using defaults" message,
and the default config options within menuconfig are rather blank (e.g.
no PCI support). You can work around this by explicitly running "make
defconfig" before menuconfig, but it would be nice to have the behaviour
the way it was for 2.6.23 (and the way it still is for other archs).
I've looked into the problem. It works on 2.6.23 because of init/Kconfig
which is still unchanged:
arch/i386/defconfig and arch/x86_64/defconfig existed in 2.6.23, but not
in 2.6.24 due to the arch merge.
I've identified why it worked in 2.6.23 but I'm not really sure of the
right way to fix it for the newer kernels. I tried adding another
default in DEFCONFIG_LIST:
but it seems that $SRCARCH and $KBUILD_DEFCONFIG are not being exported
to kconfig and I couldn't immediately see how to change that.
