123 help
124 This kernel feature is useful for number crunching applications
125 that may need to compute untrusted bytecode during their
126 execution. By using pipes or other transports made available to
127 the process as file descriptors supporting the read/write
128 syscalls, it's possible to isolate those applications in
129 their own address space using seccomp. Once seccomp is
130 enabled via /proc/<pid>/seccomp, it cannot be disabled
131 and the task is only allowed to execute a few safe syscalls
132 defined by each seccomp mode.
133
134 If unsure, say Y. Only embedded should say N here.

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