 105          On some architectures there is currently no way for the boot loader
 106          to pass arguments to the kernel. For these architectures, you should

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

 142          This option will enable prompting for a variety of advanced kernel
 143          configuration options.  These options can cause the kernel to not
 144          work if they are set incorrectly, but can be used to optimize certain
 145          aspects of kernel memory management.

 157          This is needed to be able to allocate uncachable memory regions.
 158          The feature requires the design to define the RAM memory controller
 159          window to be twice as large as the actual physical memory.

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

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

 194          Set this option to have the kernel override the CPU Reset vector.
 195          If zero, no change will be made to the MicroBlaze reset vector at
 196          address 0x0.
 197          If non-zero, a jump instruction to this address, will be written
 198          to the reset vector at address 0x0.

 206          the kernel will map low memory (the kernel image will be linked at
 207          this address).  This can be useful in optimizing the virtual memory
 208          layout of the system.

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