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.
This function is Linux specific, and should not be used in programs
intended to be portable, or indeed in any programs at all. Since Linux
2.1.121, no such function exists anymore. The calling sequence varied:
it has had a single parameter void * BIOS and at other times a single
parameter int magic.
