1855 default "11"
1856 help
1857 The kernel memory allocator divides physically contiguous memory
1858 blocks into "zones", where each zone is a power of two number of
1859 pages. This option selects the largest power of two that the kernel
1860 keeps in the memory allocator. If you need to allocate very large
1861 blocks of physically contiguous memory, then you may need to
1862 increase this value.
1863
1864 This config option is actually maximum order plus one. For example,
1865 a value of 11 means that the largest free memory block is 2^10 pages.
1866
1867 The page size is not necessarily 4KB. Keep this in mind
1868 when choosing a value for this option.

1939 This is a kernel model which is known a VSMP but lately has been
1940 marketesed into SMVP.
1941 Virtual SMP uses the processor's VPEs to implement virtual
1942 processors. In currently available configuration of the 34K processor
1943 this allows for a dual processor. Both processors will share the same
1944 primary caches; each will obtain the half of the TLB for it's own
1945 exclusive use. For a layman this model can be described as similar to
1946 what Intel calls Hyperthreading.

1965 is presenting the available TC's of the core as processors to Linux.
1966 On currently available 34K processors this means a Linux system will
1967 see up to 5 processors. The implementation of the SMTC kernel differs
1968 significantly from VSMP and cannot efficiently coexist in the same
1969 kernel binary so the choice between VSMP and SMTC is a compile time
1970 decision.

2356 help
2357 kexec is a system call that implements the ability to shutdown your
2358 current kernel, and to start another kernel. It is like a reboot
3dde6ad8 2359 but it is independent of the system firmware. And like a reboot
ea6e942b

2360 you can start any kernel with it, not just Linux.
2361
01dd2fbf 2362 The name comes from the similarity to the exec system call.

2364 It is an ongoing process to be certain the hardware in a machine
2365 is properly shutdown, so do not be surprised if this code does not
2366 initially work for you. It may help to enable device hotplugging
2367 support. As of this writing the exact hardware interface is
2368 strongly in flux, so no good recommendation can be made.

2374 help
2375 This kernel feature is useful for number crunching applications
2376 that may need to compute untrusted bytecode during their
2377 execution. By using pipes or other transports made available to
2378 the process as file descriptors supporting the read/write
2379 syscalls, it's possible to isolate those applications in
2380 their own address space using seccomp. Once seccomp is
2381 enabled via /proc/<pid>/seccomp, it cannot be disabled
2382 and the task is only allowed to execute a few safe syscalls
2383 defined by each seccomp mode.
2384
2385 If unsure, say Y. Only embedded should say N here.

2447 The Extended Industry Standard Architecture (EISA) bus was
2448 developed as an open alternative to the IBM MicroChannel bus.
2449
2450 The EISA bus provided some of the features of the IBM MicroChannel
2451 bus while maintaining backward compatibility with cards made for
2452 the older ISA bus. The EISA bus saw limited use between 1988 and
2453 1995 when it was made obsolete by the PCI bus.
