Custom build 64 bit kernel do not run 32 bit apps

I build a custom kernel ,64 bit for a tablet asus t100 . Using this custom kernel everthing works very good ,wifi bluetooth etc , but my ubuntu x64 do nit run 32 bit apps . I think it must be the kernel because when i boot default ubuntu kernel the 32 bit apps works . Is there a specific kernel configure option that I have to enable so my custom kernel to run 32 bit apps? Thank you

It's likely that you've left out a kernel configuration option to enable support for 32-bit binaries. Do you have CONFIG_IA32_EMULATION defined in your custom kernel?

If not, enable it through the make menuconfig interface, and rebuild.
