hi,

i noticed that 2.6.14-mm2 does not generate a .config.old anymore, so that 
i can undo changes. i see that the Kconfig system is probably in flux 
again ("Why did oldconfig's behavior change in 2.6.15-rc1?"), but i have 
not seen this issue being reported:

% cp .config .config.really-old
% make menuconfig
[...]
scripts/kconfig/mconf arch/x86_64/Kconfig
#
# using defaults found in .config
#

*** End of Linux kernel configuration.
*** Execute 'make' to build the kernel or try 'make help'.

% diff .config.really-old .config
4c4
< # Tue Nov 15 00:23:53 2005
---
 > # Tue Nov 15 00:24:41 2005
1454c1454
< CONFIG_PRINTK_TIME=y
---
 > # CONFIG_PRINTK_TIME is not set

% ls .config.old
ls: .config.old: No such file or directory

attached patch reverts one change introduced in 2.6.14-mm1 and fixes it 
for me, but i doubt that it is the right thing to do....

thanks,
Christian.
