Intel has officially abandoned this project and does not want to
maintian it or have it included in the main kernel tree, as no one
should use the code, it's not needed anymore.

drivers/staging/heci/TODO

-TODO:
-	- fix user/kernel pointer mess in the ioctl handlers as pointed
-	  out by sparse.
-	- resolve the ioctls and see if most of them can just be simple
-	  sysfs files
-	- fix locking issues that sparse points out at the least.
