1851 Select this option if you want to run o32 binaries. These are pure
1852 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
1853 existing binaries are in this format.
1858 bool "Kernel support for n32 binaries"
1859 depends on MIPS32_COMPAT
1861 Select this option if you want to run n32 binaries. These are
1862 64-bit binaries using 32-bit quantities for addressing and certain
1863 data that would normally be 64-bit. They are used in special
1870 default y if MIPS32_O32 || MIPS32_N32
1873 bool "Enable seccomp to safely compute untrusted bytecode"
1874 depends on PROC_FS && BROKEN
1877 This kernel feature is useful for number crunching applications
1878 that may need to compute untrusted bytecode during their
1879 execution. By using pipes or other transports made available to
1880 the process as file descriptors supporting the read/write
1881 syscalls, it's possible to isolate those applications in
1882 their own address space using seccomp. Once seccomp is
1883 enabled via /proc/<pid>/seccomp, it cannot be disabled
1884 and the task is only allowed to execute a few safe syscalls
1885 defined by each seccomp mode.
1887 If unsure, say Y. Only embedded should say N here.
1890 bool "Power Management support (EXPERIMENTAL)"
1891 depends on EXPERIMENTAL && SOC_AU1X00
