1856 execution. By using pipes or other transports made available to
1857 the process as file descriptors supporting the read/write
1858 syscalls, it's possible to isolate those applications in
1859 their own address space using seccomp. Once seccomp is
1860 enabled via /proc/<pid>/seccomp, it cannot be disabled
1861 and the task is only allowed to execute a few safe syscalls
1862 defined by each seccomp mode.
1864 If unsure, say Y. Only embedded should say N here.
1867 bool "Power Management support (EXPERIMENTAL)"
1868 depends on EXPERIMENTAL && SOC_AU1X00
