Lianbo Jiang 66ff48ed68 s390x: add kdump sysconfig option to use the kexec_file_load() syscall
Currently, kernel has supported the kexec_file_load() syscall on s390x,
so I follow this commit:
6a20bd5447 ("kdump-lib: switch to the kexec_file_load() syscall on
x86_64 by default")

And also enable the kexec_file_load() syscall for kdump on s390x by
default.

# Kernel Version string for the -kdump kernel, such as 2.6.13-1544.FC5kdump

# kdump kernel with the same version number as the running kernel.
KDUMP_KERNELVER=""
# The kdump commandline is the command line that needs to be passed off to
# the kdump kernel. This will likely match the contents of the grub kernel
# line. For example:
# KDUMP_COMMANDLINE="ro root=LABEL=/"
# Dracut depends on proper root= options, so please make sure that appropriate
# root= options are copied from /proc/cmdline. In general it is best to append
# command line options using "KDUMP_COMMANDLINE_APPEND=".
# If a command line is not specified, the default will be taken from
# /proc/cmdline
KDUMP_COMMANDLINE=""
# This variable lets us remove arguments from the current kdump commandline
# as taken from either KDUMP_COMMANDLINE above, or from /proc/cmdline
# NOTE: some arguments such as crashkernel will always be removed

# Any additional kexec arguments required. In most situations, this should

# KEXEC_ARGS="--elf32-core-headers"
KEXEC_ARGS=""
#Where to find the boot image

#What is the image type used for kdump
KDUMP_IMG="vmlinuz"
#What is the images extension. Relocatable kernels don't have one
KDUMP_IMG_EXT=""
# Using kexec file based syscall by default
#
# Here, the "on" is the only valid value to enable the kexec file load and
# anything else is equal to the "off"(disable).
