2 * System call callback functions for SPUs
7 #include <linux/kallsyms.h>
8 #include <linux/module.h>
9 #include <linux/syscalls.h>
12 #include <asm/syscalls.h>
13 #include <asm/unistd.h>
16 * This table defines the system calls that an SPU can call.
17 * It is currently a subset of the 64 bit powerpc system calls,
18 * with the exact semantics.
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
33 * mbind, mq_open, ipc, ...
