1474 Loongson 2F03 and later have fixed these issues and no workarounds
1475 are needed. The workarounds have no significant side effect on them
1476 but may decrease the performance of the system so this option should
1477 be disabled unless the kernel is intended to be run on 2F01 or 2F02

2384 This kernel feature is useful for number crunching applications
2385 that may need to compute untrusted bytecode during their
2386 execution. By using pipes or other transports made available to
2387 the process as file descriptors supporting the read/write
2388 syscalls, it's possible to isolate those applications in
2389 their own address space using seccomp. Once seccomp is
2390 enabled via /proc/<pid>/seccomp, it cannot be disabled
2391 and the task is only allowed to execute a few safe syscalls

2401 When this is enabled, the kernel will support use of 64-bit floating
2402 point registers with binaries using the O32 ABI along with the
2403 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2404 32-bit MIPS systems this support is at the cost of increasing the
2405 size and complexity of the compiled FPU emulator. Thus if you are
2406 running a MIPS32 system and know that none of your userland binaries
2407 will require 64-bit floating point, you may wish to reduce the size
2408 of your kernel & potentially improve FP emulation performance by
