19 *
20 * The reasons for disabling some of the system calls are:
21 * 1. They interact with the way SPU syscalls are handled
22 * and we can't let them execute ever:
23 * restart_syscall, exit, for, execve, ptrace, ...
24 * 2. They are deprecated and replaced by other means:
25 * uselib, pciconfig_*, sysfs, ...
26 * 3. They are somewhat interacting with the system in a way
27 * we don't want an SPU to:
28 * reboot, init_module, mount, kexec_load
29 * 4. They are optional and we can't rely on them being
30 * linked into the kernel. Unfortunately, the cond_syscall
31 * helper does not work here as it does not add the necessary
32 * opd symbols:
33 * mbind, mq_open, ipc, ...
