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

-
- If you say N here, the kernel will run on single and multiprocessor
- machines, but will use only one CPU of a multiprocessor machine. If
- you say Y here, the kernel will run on single-processor machines.
- On a single-processor machine, the kernel will run faster if you say
- N here.

- Say Y here if you want to attach PCMCIA- or PC-cards to your Linux

- actually two varieties of these cards: the older 16 bit PCMCIA cards
- and the newer 32 bit CardBus cards. If you want to use CardBus
- cards, you need to say Y here and also to "CardBus support" below.
-
- To use your PC-cards, you will need supporting software from David
- Hinds' pcmcia-cs package (see the file <file:Documentation/Changes>
- for location). Please also read the PCMCIA-HOWTO, available from
- <http://www.tldp.org/docs.html#howto>.
-

- modules will be called pcmcia_core and ds.

- use one (such as SILO). This is most useful if you want to boot
- a kernel from TFTP, and want default options to be available
- with having them passed on the command line.
