1481 are needed. The workarounds have no significant side effect on them

1871 This is a kernel model which is known a VSMP but lately has been
1872 marketesed into SMVP.
1873 Virtual SMP uses the processor's VPEs to implement virtual
1874 processors. In currently available configuration of the 34K processor
1875 this allows for a dual processor. Both processors will share the same
1876 primary caches; each will obtain the half of the TLB for it's own
1877 exclusive use. For a layman this model can be described as similar to
1878 what Intel calls Hyperthreading.

1897 is presenting the available TC's of the core as processors to Linux.
1898 On currently available 34K processors this means a Linux system will
1899 see up to 5 processors. The implementation of the SMTC kernel differs
1900 significantly from VSMP and cannot efficiently coexist in the same
1901 kernel binary so the choice between VSMP and SMTC is a compile time

2304config CRASH_DUMP
2305 bool "Kernel crash dumps"
2306 help
2307 Generate crash dump after being started by kexec.
2308 This should be normally only set in special crash dump kernels
2309 which are loaded in the main kernel with kexec-tools into
2310 a specially reserved region and then later executed after
2311 a crash by kdump/kexec. The crash dump kernel must be compiled
2312 to a memory address not used by the main kernel or firmware using
2313 PHYSICAL_START.
2314
2315config PHYSICAL_START

2319 depends on CRASH_DUMP
2320 help
2321 This gives the CKSEG0 or KSEG0 address where the kernel is loaded.
2322 If you plan to use kernel for capturing the crash dump change
2323 this value to start of the reserved region (the "X" value as
2324 specified in the "crashkernel=YM@XM" command line boot parameter
2325 passed to the panic-ed kernel).

2330 default y
2331 help
2332 This kernel feature is useful for number crunching applications
2333 that may need to compute untrusted bytecode during their
2334 execution. By using pipes or other transports made available to
2335 the process as file descriptors supporting the read/write
2336 syscalls, it's possible to isolate those applications in
2337 their own address space using seccomp. Once seccomp is
2338 enabled via /proc/<pid>/seccomp, it cannot be disabled
2339 and the task is only allowed to execute a few safe syscalls
2340 defined by each seccomp mode.
2341
2342 If unsure, say Y. Only embedded should say N here.

2344config CC_STACKPROTECTOR
2345 bool "Enable -fstack-protector buffer overflow detection (EXPERIMENTAL)"
2346 help
2347 This option turns on the -fstack-protector GCC feature. This
2348 feature puts, at the beginning of functions, a canary value on
2349 the stack just before the return address, and validates
2350 the value just before actually returning. Stack based buffer
2351 overflows (that need to overwrite this return address) now also
2352 overwrite the canary, which gets detected and the attack is then
2353 neutralized via a kernel panic.
2354
2355 This feature requires gcc version 4.2 or above.

2416 The Extended Industry Standard Architecture (EISA) bus was
2417 developed as an open alternative to the IBM MicroChannel bus.
2418
2419 The EISA bus provided some of the features of the IBM MicroChannel
2420 bus while maintaining backward compatibility with cards made for
2421 the older ISA bus. The EISA bus saw limited use between 1988 and
2422 1995 when it was made obsolete by the PCI bus.
