[patch 44/47] Kconfig: introduce ARCH_DEFCONFIG to DEFCONFIG_LIST

[Greg KH]

-stable review patch.  If anyone has any objections, please let us know.

------------------
From: Sam Ravnborg <sam@xxxxxxxxxxxx>

commit 73531905ed53576d9e8707659a761e7046a60497 in mainline.

init/Kconfig contains a list of configs that are searched
for if 'make *config' are used with no .config present.
Extend this list to look at the config identified by
ARCH_DEFCONFIG.

With this change we now try the defconfig targets last.

This fixes a regression reported
