Paul Mundt8a655052008-12-17 15:06:54 +0900627 This adds the cpufreq driver for SuperH. Any CPU that supports
628 clock rate rounding through the clock framework can use this
629 driver. While it will make the kernel slightly larger, this is
630 harmless for CPUs that don't support rate rounding. The driver
631 will also generate a notice in the boot log before disabling
632 itself if the CPU in question is not capable of rate rounding.

652 kexec is a system call that implements the ability to shutdown your
653 current kernel, and to start another kernel. It is like a reboot
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400654 but it is independent of the system firmware. And like a reboot
Paul Mundtcad82442006-01-16 22:14:19 -0800655 you can start any kernel with it, not just Linux.
656
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400657 The name comes from the similarity to the exec system call.
Paul Mundtcad82442006-01-16 22:14:19 -0800658
659 It is an ongoing process to be certain the hardware in a machine
660 is properly shutdown, so do not be surprised if this code does not
661 initially work for you. It may help to enable device hotplugging
662 support. As of this writing the exact hardware interface is
663 strongly in flux, so no good recommendation can be made.

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

719 the stack just before the return address, and validates

721 overflows (that need to overwrite this return address) now also
722 overwrite the canary, which gets detected and the attack is then
723 neutralized via a kernel panic.
