1568 Loongson 2F03 and later have fixed these issues and no workarounds
1569 are needed. The workarounds have no significant side effect on them

1855 The kernel memory allocator divides physically contiguous memory
1856 blocks into "zones", where each zone is a power of two number of
1857 pages. This option selects the largest power of two that the kernel
1858 keeps in the memory allocator. If you need to allocate very large
1859 blocks of physically contiguous memory, then you may need to
1860 increase this value.
1861
1862 This config option is actually maximum order plus one. For example,
1863 a value of 11 means that the largest free memory block is 2^10 pages.
1864
1865 The page size is not necessarily 4KB. Keep this in mind
1866 when choosing a value for this option.

1937 This is a kernel model which is known a VSMP but lately has been
1938 marketesed into SMVP.
1939 Virtual SMP uses the processor's VPEs to implement virtual
1940 processors. In currently available configuration of the 34K processor
1941 this allows for a dual processor. Both processors will share the same
1942 primary caches; each will obtain the half of the TLB for it's own
1943 exclusive use. For a layman this model can be described as similar to
1944 what Intel calls Hyperthreading.

1963 is presenting the available TC's of the core as processors to Linux.
1964 On currently available 34K processors this means a Linux system will
1965 see up to 5 processors. The implementation of the SMTC kernel differs
1966 significantly from VSMP and cannot efficiently coexist in the same
1967 kernel binary so the choice between VSMP and SMTC is a compile time
1968 decision.

2354 help
2355 kexec is a system call that implements the ability to shutdown your
2356 current kernel, and to start another kernel. It is like a reboot
3dde6ad8 2357 but it is independent of the system firmware. And like a reboot
ea6e942b

2358 you can start any kernel with it, not just Linux.
2359
01dd2fbf 2360 The name comes from the similarity to the exec system call.

2362 It is an ongoing process to be certain the hardware in a machine
2363 is properly shutdown, so do not be surprised if this code does not
2364 initially work for you. It may help to enable device hotplugging
2365 support. As of this writing the exact hardware interface is
2366 strongly in flux, so no good recommendation can be made.

2372 help
2373 This kernel feature is useful for number crunching applications
2374 that may need to compute untrusted bytecode during their
2375 execution. By using pipes or other transports made available to
2376 the process as file descriptors supporting the read/write
2377 syscalls, it's possible to isolate those applications in
2378 their own address space using seccomp. Once seccomp is
2379 enabled via /proc/<pid>/seccomp, it cannot be disabled
2380 and the task is only allowed to execute a few safe syscalls
2381 defined by each seccomp mode.
2382
2383 If unsure, say Y. Only embedded should say N here.

2445 The Extended Industry Standard Architecture (EISA) bus was
2446 developed as an open alternative to the IBM MicroChannel bus.
2447
2448 The EISA bus provided some of the features of the IBM MicroChannel
2449 bus while maintaining backward compatibility with cards made for
2450 the older ISA bus. The EISA bus saw limited use between 1988 and
2451 1995 when it was made obsolete by the PCI bus.
