Steven Rostedt 4025bc62dd ktest: Reboot to good kernel after every bisect run 
Reboot after each bisect run regardless if the bisect passed
or failed. The test may just be to boot the kernel and that kernel
may not have a way to copy the next kerne to it. Reboot to a known
good kernel after each bisect run.

$config_help{"MACHINE"} = << "EOF"
The machine hostname that you will test.
EOF
;
$config_help{"SSH_USER"} = << "EOF"
The box is expected to have ssh on normal bootup, provide the user
(most likely root, since you need privileged operations)
EOF
;
$config_help{"BUILD_DIR"} = << "EOF"
The directory that contains the Linux source code (full path).
EOF
;
$config_help{"OUTPUT_DIR"} = << "EOF"
The directory that the objects will be built (full path).
(can not be same as BUILD_DIR)
EOF
;
$config_help{"BUILD_TARGET"} = << "EOF"
The location of the compiled file to copy to the target.
(relative to OUTPUT_DIR)
EOF
;
$config_help{"TARGET_IMAGE"} = << "EOF"
The place to put your image on the test machine.
EOF
;
$config_help{"POWER_CYCLE"} = << "EOF"
A script or command to reboot the box.
Here is a digital loggers power switch example
POWER_CYCLE = wget --no-proxy -O /dev/null -q --auth-no-challenge 'http://admin:admin\@power/outlet?5=CCL'
Here is an example to reboot a virtual box on the current host
with the name "Guest".
POWER_CYCLE = virsh destroy Guest; sleep 5; virsh start Guest
EOF
;
$config_help{"CONSOLE"} = << "EOF"
The script or command that reads the console
If you use ttywatch server, something like the following would work.
CONSOLE = nc -d localhost 3001
For a virtual machine with guest name "Guest".
CONSOLE = virsh console Guest
EOF
;
$config_help{"LOCALVERSION"} = << "EOF"
Required version ending to differentiate the test
from other linux builds on the system.
EOF
;
$config_help{"REBOOT_TYPE"} = << "EOF"
Way to reboot the box to the test kernel.
Only valid options so far are "grub" and "script".
If you specify grub, it will assume grub version 1
and will search in /boot/grub/menu.lst for the title \$GRUB_MENU
and select that target to reboot to the kernel. If this is not
your setup, then specify "script" and have a command or script
specified in REBOOT_SCRIPT to boot to the target.
The entry in /boot/grub/menu.lst must be entered in manually.
The test will not modify that file.
EOF
;
$config_help{"GRUB_MENU"} = << "EOF"
The grub title name for the test kernel to boot
(Only mandatory if REBOOT_TYPE = grub)
Note, ktest.pl will not update the grub menu.lst, you need to
manually add an option for the test. ktest.pl will search
the grub menu.lst for this option to find what kernel to
reboot into.
For example, if in the /boot/grub/menu.lst the test kernel title has:
title Test Kernel
kernel vmlinuz-test
GRUB_MENU = Test Kernel
EOF
;
$config_help{"REBOOT_SCRIPT"} = << "EOF"
A script to reboot the target into the test kernel
(Only mandatory if REBOOT_TYPE = script)
