1581 Loongson 2F03 and later have fixed these issues and no workarounds
1582 are needed. The workarounds have no significant side effect on them
1583 but may decrease the performance of the system so this option should
1584 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1585 systems.

1869 The kernel memory allocator divides physically contiguous memory
1870 blocks into "zones", where each zone is a power of two number of
1871 pages. This option selects the largest power of two that the kernel
1872 keeps in the memory allocator. If you need to allocate very large
1873 blocks of physically contiguous memory, then you may need to
1874 increase this value.
1875
1876 This config option is actually maximum order plus one. For example,
1877 a value of 11 means that the largest free memory block is 2^10 pages.
1878
1879 The page size is not necessarily 4KB. Keep this in mind
1880 when choosing a value for this option.

1951 This is a kernel model which is known a VSMP but lately has been
1952 marketesed into SMVP.
1953 Virtual SMP uses the processor's VPEs to implement virtual
1954 processors. In currently available configuration of the 34K processor
1955 this allows for a dual processor. Both processors will share the same
1956 primary caches; each will obtain the half of the TLB for it's own
1957 exclusive use. For a layman this model can be described as similar to
1958 what Intel calls Hyperthreading.

1977 is presenting the available TC's of the core as processors to Linux.
1978 On currently available 34K processors this means a Linux system will
1979 see up to 5 processors. The implementation of the SMTC kernel differs
1980 significantly from VSMP and cannot efficiently coexist in the same
1981 kernel binary so the choice between VSMP and SMTC is a compile time
1982 decision.

2369 kexec is a system call that implements the ability to shutdown your
2370 current kernel, and to start another kernel. It is like a reboot
3dde6ad8 2371 but it is independent of the system firmware. And like a reboot
ea6e942b

2372 you can start any kernel with it, not just Linux.

2376 It is an ongoing process to be certain the hardware in a machine
2377 is properly shutdown, so do not be surprised if this code does not
2378 initially work for you. It may help to enable device hotplugging
2379 support. As of this writing the exact hardware interface is
2380 strongly in flux, so no good recommendation can be made.

2386 help
2387 This kernel feature is useful for number crunching applications
2388 that may need to compute untrusted bytecode during their
2389 execution. By using pipes or other transports made available to
2390 the process as file descriptors supporting the read/write
2391 syscalls, it's possible to isolate those applications in
2392 their own address space using seccomp. Once seccomp is
2393 enabled via /proc/<pid>/seccomp, it cannot be disabled
2394 and the task is only allowed to execute a few safe syscalls
2395 defined by each seccomp mode.
2396

2459 The Extended Industry Standard Architecture (EISA) bus was
2460 developed as an open alternative to the IBM MicroChannel bus.

2462 The EISA bus provided some of the features of the IBM MicroChannel
2463 bus while maintaining backward compatibility with cards made for
2464 the older ISA bus. The EISA bus saw limited use between 1988 and
2465 1995 when it was made obsolete by the PCI bus.
