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

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