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

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

176 will be used as "low memory", that is, memory which the kernel can
177 access directly, without having to set up a kernel virtual mapping.

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