1464 Loongson 2F03 and later have fixed these issues and no workarounds

1855 This is a kernel model which is known a VSMP but lately has been
1856 marketesed into SMVP.
1857 Virtual SMP uses the processor's VPEs to implement virtual
1858 processors. In currently available configuration of the 34K processor
1859 this allows for a dual processor. Both processors will share the same
1860 primary caches; each will obtain the half of the TLB for it's own
1861 exclusive use. For a layman this model can be described as similar to
1862 what Intel calls Hyperthreading.

1881 is presenting the available TC's of the core as processors to Linux.
1882 On currently available 34K processors this means a Linux system will
1883 see up to 5 processors. The implementation of the SMTC kernel differs
1884 significantly from VSMP and cannot efficiently coexist in the same
1885 kernel binary so the choice between VSMP and SMTC is a compile time
1886 decision.

2290 Generate crash dump after being started by kexec.
2291 This should be normally only set in special crash dump kernels
2292 which are loaded in the main kernel with kexec-tools into
2293 a specially reserved region and then later executed after
2294 a crash by kdump/kexec. The crash dump kernel must be compiled
2295 to a memory address not used by the main kernel or firmware using
2296 PHYSICAL_START.
2297
2298config PHYSICAL_START
2299 hex "Physical address where the kernel is loaded"
2300 default "0xffffffff84000000" if 64BIT
2301 default "0x84000000" if 32BIT
2302 depends on CRASH_DUMP
2303 help
2304 This gives the CKSEG0 or KSEG0 address where the kernel is loaded.
2305 If you plan to use kernel for capturing the crash dump change
2306 this value to start of the reserved region (the "X" value as
2307 specified in the "crashkernel=YM@XM" command line boot parameter
2308 passed to the panic-ed kernel).

2314 help
2315 This kernel feature is useful for number crunching applications
2316 that may need to compute untrusted bytecode during their
2317 execution. By using pipes or other transports made available to
2318 the process as file descriptors supporting the read/write
2319 syscalls, it's possible to isolate those applications in
2320 their own address space using seccomp. Once seccomp is
2321 enabled via /proc/<pid>/seccomp, it cannot be disabled
2322 and the task is only allowed to execute a few safe syscalls
2323 defined by each seccomp mode.
2324
2325 If unsure, say Y. Only embedded should say N here.

2386 The Extended Industry Standard Architecture (EISA) bus was
2387 developed as an open alternative to the IBM MicroChannel bus.
2388
2389 The EISA bus provided some of the features of the IBM MicroChannel
2390 bus while maintaining backward compatibility with cards made for
2391 the older ISA bus. The EISA bus saw limited use between 1988 and
2392 1995 when it was made obsolete by the PCI bus.
2393
2394 Say Y here if you are building a kernel for an EISA-based machine.
