configs (plural). All of them are randconfigs. All on x86_64.

The randconfig files are attached.

I have been wondering lately if I could just tell you/other people the
randconfig SEED that was used and then you/other people could just use
that SEED to reproduce the randconfig file(s).
Are rand() and srand() stable across GCC versions and h/w platforms?

config-r9247:KCONFIG_SEED=0x7ABE8042
config-r9251:KCONFIG_SEED=0x67B989AA
config-r9253:KCONFIG_SEED=0x7B3D63BE
config-r9254:KCONFIG_SEED=0x331557C5


Usage:
KCONFIG_SEED=0x331557C5 make [ARCH=x86_64] [O=builddir] randconfig

thanks.
