969 Some MIPS machines can be configured for either little or big endian
5e83d430 970 byte order. These modes require different kernels and a different

1445 Loongson 2F03 and later have fixed these issues and no workarounds

2293 Generate crash dump after being started by kexec.
2294 This should be normally only set in special crash dump kernels
2295 which are loaded in the main kernel with kexec-tools into
2296 a specially reserved region and then later executed after
2297 a crash by kdump/kexec. The crash dump kernel must be compiled
2298 to a memory address not used by the main kernel or firmware using
2299 PHYSICAL_START.
2300
2301config PHYSICAL_START
2302 hex "Physical address where the kernel is loaded"
2303 default "0xffffffff84000000" if 64BIT
2304 default "0x84000000" if 32BIT
2305 depends on CRASH_DUMP
2306 help
2307 This gives the CKSEG0 or KSEG0 address where the kernel is loaded.
2308 If you plan to use kernel for capturing the crash dump change
2309 this value to start of the reserved region (the "X" value as
2310 specified in the "crashkernel=YM@XM" command line boot parameter
2311 passed to the panic-ed kernel).

2317 help
2318 This kernel feature is useful for number crunching applications
2319 that may need to compute untrusted bytecode during their
2320 execution. By using pipes or other transports made available to
2321 the process as file descriptors supporting the read/write
2322 syscalls, it's possible to isolate those applications in
2323 their own address space using seccomp. Once seccomp is
2324 enabled via /proc/<pid>/seccomp, it cannot be disabled
2325 and the task is only allowed to execute a few safe syscalls
2326 defined by each seccomp mode.
2327
2328 If unsure, say Y. Only embedded should say N here.

2330config CC_STACKPROTECTOR
2331 bool "Enable -fstack-protector buffer overflow detection (EXPERIMENTAL)"
2332 help
2333 This option turns on the -fstack-protector GCC feature. This
2334 feature puts, at the beginning of functions, a canary value on
2335 the stack just before the return address, and validates
2336 the value just before actually returning. Stack based buffer
2337 overflows (that need to overwrite this return address) now also
2338 overwrite the canary, which gets detected and the attack is then
2339 neutralized via a kernel panic.
2340
2341 This feature requires gcc version 4.2 or above.

2344 bool "Support for O32 binaries using 64-bit FP"
2345 depends on 32BIT || MIPS32_O32
2346 default y
2347 help
2348 When this is enabled, the kernel will support use of 64-bit floating
2349 point registers with binaries using the O32 ABI along with the
2350 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2351 32-bit MIPS systems this support is at the cost of increasing the
2352 size and complexity of the compiled FPU emulator. Thus if you are
2353 running a MIPS32 system and know that none of your userland binaries
2354 will require 64-bit floating point, you may wish to reduce the size
2355 of your kernel & potentially improve FP emulation performance by
2356 saying N here.

2419 The Extended Industry Standard Architecture (EISA) bus was
2420 developed as an open alternative to the IBM MicroChannel bus.

2422 The EISA bus provided some of the features of the IBM MicroChannel
2423 bus while maintaining backward compatibility with cards made for
2424 the older ISA bus. The EISA bus saw limited use between 1988 and
2425 1995 when it was made obsolete by the PCI bus.
