1266 Please make sure to pick the right CPU type. Linux/MIPS is not
1267 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1268 *not* work on R4000 machines and vice versa. However, since most
1269 of the supported machines have an R4000 (or similar) CPU, R4x00
1270 might be a safe bet. If the resulting kernel does not work,
1271 try to recompile with R3000.

1830 marketesed into SMVP.
1831 Virtual SMP uses the processor's VPEs to implement virtual
1832 processors. In currently available configuration of the 34K processor
1833 this allows for a dual processor. Both processors will share the same
1834 primary caches; each will obtain the half of the TLB for it's own
1835 exclusive use. For a layman this model can be described as similar to
1836 what Intel calls Hyperthreading.

2277 It is an ongoing process to be certain the hardware in a machine
2278 is properly shutdown, so do not be surprised if this code does not
2279 initially work for you. It may help to enable device hotplugging
2280 support. As of this writing the exact hardware interface is
2281 strongly in flux, so no good recommendation can be made.

2288 This kernel feature is useful for number crunching applications
2289 that may need to compute untrusted bytecode during their
2290 execution. By using pipes or other transports made available to
2291 the process as file descriptors supporting the read/write
2292 syscalls, it's possible to isolate those applications in
2293 their own address space using seccomp. Once seccomp is
2294 enabled via /proc/<pid>/seccomp, it cannot be disabled
2295 and the task is only allowed to execute a few safe syscalls
2296 defined by each seccomp mode.

2357 The Extended Industry Standard Architecture (EISA) bus was
2358 developed as an open alternative to the IBM MicroChannel bus.
2359
2360 The EISA bus provided some of the features of the IBM MicroChannel
2361 bus while maintaining backward compatibility with cards made for
2362 the older ISA bus. The EISA bus saw limited use between 1988 and
2363 1995 when it was made obsolete by the PCI bus.
