Hi,
I'm currently configuring a custom kernel on Fedora x86_64. The first
option on the configuration menu is "64-bit kernel" which I think is
the only option controlling the architecture of kernel. Copying this
.config file to a 32-bit system directly and turning off this option,
can I compile a 32-bit kernel which doesn't have any hidden problems?
If this way is feasible, I think the only difference between these two
kernels is architecture.
Regards,
Hao Lee

Hi
To the best I could recall, 32 vs 64 bit mainly affect vm split. in 32 bit, you have 3:1, in 64 bit, there is none and I am not sure that is automatically decided by Kconfig simply by selecting 32 or 64 bit arch.
