The most obvious solution would be to export the function
prototypes for all userspace-used functions to userspace.
Plus we need to export the prototypes for module-exported
functions (kernel/ksyms.c) in a for-modules include file.

Maybe we can even build these include files automatically,
since these functions are exported explicitly (for modules
in <kernel/ksyms.c> and syscalls in <entry.S>.
