1890 This is a kernel model which is known a VSMP but lately has been
1891 marketesed into SMVP.
1892 Virtual SMP uses the processor's VPEs to implement virtual
1893 processors. In currently available configuration of the 34K processor
1894 this allows for a dual processor. Both processors will share the same
1895 primary caches; each will obtain the half of the TLB for it's own
1896 exclusive use. For a layman this model can be described as similar to
1897 what Intel calls Hyperthreading.

1916 is presenting the available TC's of the core as processors to Linux.
1917 On currently available 34K processors this means a Linux system will
1918 see up to 5 processors. The implementation of the SMTC kernel differs
1919 significantly from VSMP and cannot efficiently coexist in the same
1920 kernel binary so the choice between VSMP and SMTC is a compile time
1921 decision.

2316 It is an ongoing process to be certain the hardware in a machine
2317 is properly shutdown, so do not be surprised if this code does not
2318 initially work for you. It may help to enable device hotplugging
2319 support. As of this writing the exact hardware interface is
2320 strongly in flux, so no good recommendation can be made.

2324 help
2325 Generate crash dump after being started by kexec.
2326 This should be normally only set in special crash dump kernels
2327 which are loaded in the main kernel with kexec-tools into
2328 a specially reserved region and then later executed after
2329 a crash by kdump/kexec. The crash dump kernel must be compiled
2330 to a memory address not used by the main kernel or firmware using
2331 PHYSICAL_START.

2339 This gives the CKSEG0 or KSEG0 address where the kernel is loaded.
2340 If you plan to use kernel for capturing the crash dump change
2341 this value to start of the reserved region (the "X" value as
2342 specified in the "crashkernel=YM@XM" command line boot parameter
2343 passed to the panic-ed kernel).

2350 This kernel feature is useful for number crunching applications
2351 that may need to compute untrusted bytecode during their
2352 execution. By using pipes or other transports made available to
2353 the process as file descriptors supporting the read/write
2354 syscalls, it's possible to isolate those applications in
2355 their own address space using seccomp. Once seccomp is
2356 enabled via /proc/<pid>/seccomp, it cannot be disabled
2357 and the task is only allowed to execute a few safe syscalls
2358 defined by each seccomp mode.

2422 The Extended Industry Standard Architecture (EISA) bus was
2423 developed as an open alternative to the IBM MicroChannel bus.

2425 The EISA bus provided some of the features of the IBM MicroChannel
2426 bus while maintaining backward compatibility with cards made for
2427 the older ISA bus. The EISA bus saw limited use between 1988 and
2428 1995 when it was made obsolete by the PCI bus.
