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