Module usertest 

Minimal Ring 3 test task for Strat9-OS.

Creates a user address space with a tiny machine code blob that:

1. Calls SYS_DEBUG_LOG to print “Hello Ring 3!” to serial
2. Calls SYS_PROC_EXIT to cleanly exit

This tests the full SYSCALL/SYSRET pipeline without needing an ELF loader.

Functions
