setup - setup devices and file systems, mount root file system
setup() is called once from within linux/init/main.c. It calls
initialization functions for devices and file systems configured into
the kernel and then mounts the root file system.
No user process may call setup(). Any user process, even a process
with superuser permission, will receive EPERM.
setup() always returns -1 for a user process.
EPERM Always, for a user process.
Since Linux 2.1.121, no such function exists anymore.
This function is Linux-specific, and should not be used in programs
intended to be portable, or indeed in any programs at all.
The calling sequence varied: at some times setup () has had a single
argument void *BIOS and at other times a single argument int magic.
