          On some architectures there is currently no way for the boot loader

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

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

          configuration options.  These options can cause the kernel to not
          work if they are set incorrectly, but can be used to optimize certain
          aspects of kernel memory management.

          This is needed to be able to allocate uncachable memory regions.
          The feature requires the design to define the RAM memory controller

          The address space of Microblaze processors is only 4 Gigabytes large
          and it has to accommodate user address space, kernel address
          space as well as some memory mapped IO. That means that, if you
          have a large amount of physical memory and/or IO, not all of the
          memory can be "permanently mapped" by the kernel. The physical
          memory that is not permanently mapped is called "high memory".

          This option allows you to set the maximum amount of memory which
          will be used as "low memory", that is, memory which the kernel can
          access directly, without having to set up a kernel virtual mapping.
          This can be useful in optimizing the layout of kernel virtual
          memory.

          If non-zero, a jump instruction to this address, will be written
          to the reset vector at address 0x0.

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