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

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