609 help
610 This option changes the kernel logical page size to 64k. On machines
611 without processor support for 64k pages, the kernel will simulate
612 them by loading each individual 4k page on demand transparently,
613 while on hardware with such support, it will be used to map
614 normal application pages.

928 Kprobes allows you to trap at almost any kernel address and
929 execute a callback function. register_kprobe() establishes
930 a probepoint and specifies the callback. Kprobes is useful
931 for kernel debugging, non-intrusive instrumentation and testing.

10 * There are 5 different IPL methods
11 * 1) load the image directly into ram at address 0 and do an PSW restart
12 * 2) linload will load the image from address 0x10000 to memory 0x10000
13 * and start the code thru LPSW 0x0008000080010000 (VM only, deprecated)
14 * 3) generate the tape ipl header, store the generated image on a tape
15 * and ipl from it
16 * In case of SL tape you need to IPL 5 times to get past VOL1 etc
17 * 4) generate the vm reader ipl header, move the generated image to the
18 * VM reader (use option NOH!) and do a ipl from reader (VM only)
19 * 5) direct call of start by the SALIPL loader
20 * We use the cpuid to distinguish between VM and native ipl
21 * params for kernel are pushed to 0x10400 (see setup.h)

23 Changes:
24 Okt 25 2000 <rvdheij@iae.nl>
25 added code to skip HDR and EOF to allow SL tape IPL (5 retries)
26 changed first CCW from rewind to backspace block
