This patch adds emulation for instructions protected by User-Mode
Instruction Prevention (currently only implemented by Ryzen 3000 CPUs).
I'm still working on tests but wanted to get some feedback, especially
on these topics:
- I'm currently adding the exception handler in signal_init_process()
but this doesn't feel like the right place to do it.
Is there a better place for this to go?
- the instruction emulation helper functions are copied from
ntoskrnl.exe/instr.c, would it be better to move them somewhere so
they can be shared?
