[Info-vax] Android development Was Re: OT: Larry Ellison takes retirement as CEO of Oracle

OK, based on Mr Hoffman's message, I understand that system
sercvice/user written system services are not granted privileges, they
simply get to execute in either exec or kernel mode.

However, my question still stands on how when I branch to a system
service (or user written system service), the code is magically granted
special status.  (and how that special status is revoked when it
branches back.

Side question:

When code steps into kernel mode, does it have to bother enabling
privileges needed to do the job, or does code execute with all
privileges enabled (or more like no privileges checked) ?
