601 depends on SUPERH32 && EXPERIMENTAL && MMU
602 help
603 kexec is a system call that implements the ability to shutdown your
604 current kernel, and to start another kernel. It is like a reboot
605 but it is independent of the system firmware. And like a reboot
606 you can start any kernel with it, not just Linux.
607
608 The name comes from the similarity to the exec system call.
609
610 It is an ongoing process to be certain the hardware in a machine
611 is properly shutdown, so do not be surprised if this code does not
612 initially work for you. It may help to enable device hotplugging
613 support. As of this writing the exact hardware interface is
614 strongly in flux, so no good recommendation can be made.

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

662 If you say N here, the kernel will run on single and multiprocessor
663 machines, but will use only one CPU of a multiprocessor machine. If
664 you say Y here, the kernel will run on many, but not all,

666 will run faster if you say N here.

682 help
683 This allows you to specify the maximum number of CPUs which this
684 kernel will support. The maximum supported value is 32 and the
685 minimum value which makes sense is 2.
686
687 This is purely to save memory - each supported CPU adds
688 approximately eight kilobytes to the kernel image.

696 This enables support for gUSA (general UserSpace Atomicity).
697 This is the default implementation for both UP and non-ll/sc
698 CPUs, and is used by the libc, amongst others.

700 For additional information, design information can be found
701 in <http://lc.linux.or.jp/lc2002/papers/niibe0919p.pdf>.

704 atomicity implementations exist.

709 help
710 Enabling this option will allow the kernel to implement some
711 atomic operations using a software implementation of load-locked/
712 store-conditional (LLSC). On machines which do not have hardware
713 LLSC, this should be more efficient than the other alternative of
714 disabling interrupts around the atomic sequence.

716config SPARSE_IRQ

718 depends on EXPERIMENTAL
719 help
720 This enables support for sparse irqs. This is useful in general
721 as most CPUs have a fairly sparse array of IRQ vectors, which
722 the irq_desc then maps directly on to. Systems with a high
723 number of off-chip IRQs will want to treat this as
724 experimental until they have been independently verified.

768 Selecting this option will wakeup the User Break Controller (UBC) on
769 startup. Although the UBC is left in an awake state when the processor
770 comes up, some boot loaders misbehave by putting the UBC to sleep in a
771 power saving state, which causes issues with things like ptrace().
