  90. This kernel feature is useful for number crunching applications
  91. that may need to compute untrusted bytecode during their
  92. execution. By using pipes or other transports made available to
  93. the process as file descriptors supporting the read/write
  94. syscalls, it's possible to isolate those applications in
  95. their own address space using seccomp. Once seccomp is
  96. enabled via /proc/<pid>/seccomp, it cannot be disabled
  97. and the task is only allowed to execute a few safe syscalls
  98. defined by each seccomp mode.
  99. If unsure, say Y. Only embedded should say N here.

  184. Select the kernel logical page size. Increasing the page size
  185. will reduce software overhead at each page boundary, allow
  186. hardware prefetch mechanisms to be more effective, and allow
  187. larger dma transfers increasing IO efficiency and reducing
  188. overhead. However the utilization of memory will increase.
  189. For example, each cached file will using a multiple of the
  190. page size to hold its contents and the difference between the
  191. end of file and the end of page is wasted.
