Asynchronous Kernel/User Crossing

Author: Yizhou Shan ys@purdue.edu

Some cool asynchronous kernel/user crossing stuff I’m doing.
Still WIP.

If you are interested, check out those locations:

• xing/kern_mod: kernel side module
  • NOTE: the reason to extract code and have a module

     is to avoid compiling kernel every time a line

    is changed. Yes, an extra call is introduced,
    but it greatly speedup development.
• xing/user_lib: user land library
• arch/x86/kernel/async_crossing.c: the new syscall
• arch/x86/mm/fault.c: the guy who got robbed
