1473 Loongson 2F03 and later have fixed these issues and no workarounds
1474 are needed. The workarounds have no significant side effect on them
1475 but may decrease the performance of the system so this option should

2380 This kernel feature is useful for number crunching applications
2381 that may need to compute untrusted bytecode during their
2382 execution. By using pipes or other transports made available to
2383 the process as file descriptors supporting the read/write
2384 syscalls, it's possible to isolate those applications in
2385 their own address space using seccomp. Once seccomp is

2397 When this is enabled, the kernel will support use of 64-bit floating
2398 point registers with binaries using the O32 ABI along with the
2399 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2400 32-bit MIPS systems this support is at the cost of increasing the
2401 size and complexity of the compiled FPU emulator. Thus if you are
2402 running a MIPS32 system and know that none of your userland binaries
2403 will require 64-bit floating point, you may wish to reduce the size
2404 of your kernel & potentially improve FP emulation performance by
