1463 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.

1465 Loongson 2F03 and later have fixed these issues and no workarounds
1466 are needed. The workarounds have no significant side effect on them
1467 but may decrease the performance of the system so this option should
1468 be disabled unless the kernel is intended to be run on 2F01 or 2F02

2298 kexec is a system call that implements the ability to shutdown your
2299 current kernel, and to start another kernel. It is like a reboot
3dde6ad8 2300 but it is independent of the system firmware. And like a reboot

2313 help
2314 Generate crash dump after being started by kexec.
2315 This should be normally only set in special crash dump kernels
2316 which are loaded in the main kernel with kexec-tools into
2317 a specially reserved region and then later executed after
2318 a crash by kdump/kexec. The crash dump kernel must be compiled
2319 to a memory address not used by the main kernel or firmware using
2320 PHYSICAL_START.

2328 This gives the CKSEG0 or KSEG0 address where the kernel is loaded.
2329 If you plan to use kernel for capturing the crash dump change
2330 this value to start of the reserved region (the "X" value as

2337 default y
2338 help
2339 This kernel feature is useful for number crunching applications
2340 that may need to compute untrusted bytecode during their
2341 execution. By using pipes or other transports made available to
2342 the process as file descriptors supporting the read/write
2343 syscalls, it's possible to isolate those applications in
2344 their own address space using seccomp. Once seccomp is
2345 enabled via /proc/<pid>/seccomp, it cannot be disabled
2346 and the task is only allowed to execute a few safe syscalls
2347 defined by each seccomp mode.
2348
2349 If unsure, say Y. Only embedded should say N here.

2351config CC_STACKPROTECTOR
2352 bool "Enable -fstack-protector buffer overflow detection (EXPERIMENTAL)"
2353 help
2354 This option turns on the -fstack-protector GCC feature. This
2355 feature puts, at the beginning of functions, a canary value on
2356 the stack just before the return address, and validates
2357 the value just before actually returning. Stack based buffer
2358 overflows (that need to overwrite this return address) now also
2359 overwrite the canary, which gets detected and the attack is then
2360 neutralized via a kernel panic.
2361
2362 This feature requires gcc version 4.2 or above.

2367 default y
2368 help
2369 When this is enabled, the kernel will support use of 64-bit floating
2370 point registers with binaries using the O32 ABI along with the
2371 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2372 32-bit MIPS systems this support is at the cost of increasing the
2373 size and complexity of the compiled FPU emulator. Thus if you are
2374 running a MIPS32 system and know that none of your userland binaries
2375 will require 64-bit floating point, you may wish to reduce the size
2376 of your kernel & potentially improve FP emulation performance by
2377 saying N here.

2443 The EISA bus provided some of the features of the IBM MicroChannel
2444 bus while maintaining backward compatibility with cards made for
