1900 This is a kernel model which is known a VSMP but lately has been
1901 marketesed into SMVP.
1902 Virtual SMP uses the processor's VPEs to implement virtual
1903 processors. In currently available configuration of the 34K processor
1904 this allows for a dual processor. Both processors will share the same
1905 primary caches; each will obtain the half of the TLB for it's own
1906 exclusive use. For a layman this model can be described as similar to
1907 what Intel calls Hyperthreading.

1926 is presenting the available TC's of the core as processors to Linux.
1927 On currently available 34K processors this means a Linux system will
1928 see up to 5 processors. The implementation of the SMTC kernel differs
1929 significantly from VSMP and cannot efficiently coexist in the same
1930 kernel binary so the choice between VSMP and SMTC is a compile time
1931 decision.

2325 It is an ongoing process to be certain the hardware in a machine
2326 is properly shutdown, so do not be surprised if this code does not
2327 initially work for you. It may help to enable device hotplugging
2328 support. As of this writing the exact hardware interface is
2329 strongly in flux, so no good recommendation can be made.

2334 Generate crash dump after being started by kexec.
2335 This should be normally only set in special crash dump kernels
2336 which are loaded in the main kernel with kexec-tools into
2337 a specially reserved region and then later executed after
2338 a crash by kdump/kexec. The crash dump kernel must be compiled
2339 to a memory address not used by the main kernel or firmware using
2340 PHYSICAL_START.

2348 This gives the CKSEG0 or KSEG0 address where the kernel is loaded.
2349 If you plan to use kernel for capturing the crash dump change
2350 this value to start of the reserved region (the "X" value as

2359 This kernel feature is useful for number crunching applications
2360 that may need to compute untrusted bytecode during their
2361 execution. By using pipes or other transports made available to
2362 the process as file descriptors supporting the read/write
2363 syscalls, it's possible to isolate those applications in
2364 their own address space using seccomp. Once seccomp is
2365 enabled via /proc/<pid>/seccomp, it cannot be disabled
2366 and the task is only allowed to execute a few safe syscalls
2367 defined by each seccomp mode.

2431 The Extended Industry Standard Architecture (EISA) bus was
2432 developed as an open alternative to the IBM MicroChannel bus.

2434 The EISA bus provided some of the features of the IBM MicroChannel
2435 bus while maintaining backward compatibility with cards made for
2436 the older ISA bus. The EISA bus saw limited use between 1988 and
2437 1995 when it was made obsolete by the PCI bus.
