NATIVE_FIRM
Minus configmem init, exactly 4 functions were updated in the ARM11-kernel(at least one was for fixing a security issue). See here for details on that.
Process9
One of the changes was that main() was updated. Two functions(including launch_firm()) which were previously called directly are now called via a wrapper function with a funcptr parameter. As a result, the main() prologue/epilog changed. This is for temporarily relocating the stack elsewhere(same stack for both func-calls), just for calling the funcptr(all registers except for r0..r3 are saved/restored before/after calling the funcptr).
New3DS-only
No actual code/data was changed in the arm9loader.
