   That sounds like a 32 bit OS on 64 bit hardware.  Not sure if uname -m is   
   the kernel or the hardware, but perhaps you're running a 32 bit userland on   
   a 64 bit kernel?   
      
   Seems that Pi OS switched to a 64 bit kernel on the Pi4 in March 2023:   
   https://github.com/raspberrypi/firmware/issues/1795   
      
   It looks like 'getconf' returns glibc parameters, which would be 32 bit on a   
   32 bit userland.
