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

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