50 This defines the number of virtual interrupt numbers the kernel
51 can manage. Virtual interrupt numbers are what you see in
52 /proc/interrupts. If you configure your system to have too few,
53 drivers will fail to load or worse - handle with care.

347 kexec is a system call that implements the ability to shutdown your
348 current kernel, and to start another kernel. It is like a reboot
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400349 but it is independent of the system firmware. And like a reboot
Paul Mackerras14cf11a2005-09-26 16:04:21 +1000350 you can start any kernel with it, not just Linux.
351
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400352 The name comes from the similarity to the exec system call.
Paul Mackerras14cf11a2005-09-26 16:04:21 +1000353
354 It is an ongoing process to be certain the hardware in a machine
355 is properly shutdown, so do not be surprised if this code does not
356 initially work for you. It may help to enable device hotplugging
357 support. As of this writing the exact hardware interface is
358 strongly in flux, so no good recommendation can be made.
