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

128 If unsure, say Y. Only embedded should say N here.

222 Select the kernel logical page size. Increasing the page size
223 will reduce software overhead at each page boundary, allow
224 hardware prefetch mechanisms to be more effective, and allow
225 larger dma transfers increasing IO efficiency and reducing
226 overhead. However the utilization of memory will increase.
227 For example, each cached file will using a multiple of the
228 page size to hold its contents and the difference between the
229 end of file and the end of page is wasted.
