Sigh, I missed to check which architecture Kconfig files actually include the core Kconfig file. There are a few which did not. So we broke them. Instead of adding the includes to those, we are better off to move the include to init/Kconfig like we did already with irqs and others. This does not change anything for the architectures using the old style periodic timer mode. It just solves the build wreckage there. For those architectures which use the clock events infrastructure it moves the include of the core Kconfig file to "General setup" which is a way more logical place than having it at random locations specified by the architecture specific Kconfigs.

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.

space as well as some memory mapped IO. That means that, if you

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.
