[S390] Extra Kernel Parameters via VMPARM
Now it is possible to specify additional kernel parameters on the IPL command line using the IPL PARM option. If the Linux system is already running, the new reipl sysfs attribute 'parm' can be used to change kernel parameters for the next reboot. Examples: IPL C PARM dasd=1234 root=/dev/dasda1 IPL 1234 PARM savesys=mylnxnss echo "init=/bin/bash" > /sys/firmware/reipl/ccw/parm Signed-off-by: Hendrik Brueckner <brueckner@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
