    Revert "Revert "x86_64: enable the kexec file load by default""

    This reverts commit 073c30973c, i.e.

# Kernel Version string for the -kdump kernel, such as 2.6.13-1544.FC5kdump
# If no version is specified, then the init script will try to find a
# 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
KDUMP_COMMANDLINE_REMOVE="hugepages hugepagesz slub_debug quiet log_buf_len swiotlb cma hugetlb_cma"
# This variable lets us append arguments to the current kdump commandline
# after processed by KDUMP_COMMANDLINE_REMOVE
KDUMP_COMMANDLINE_APPEND="irqpoll nr_cpus=1 reset_devices cgroup_disable=memory mce=off numa=off udev.children-max=2 panic=10 acpi_no_memhotplug transparent_hugepage=never nokaslr hest_disable novmcoredd cma=0 hugetlb_cma=0"
# Any additional kexec arguments required. In most situations, this should
# be left empty

# Example:
# KEXEC_ARGS="--elf32-core-headers"
KEXEC_ARGS="-s"

#KDUMP_BOOTDIR="/boot"
#What is the image type used for kdump
KDUMP_IMG="vmlinuz"
#What is the images extension. Relocatable kernels don't have one

# Logging is controlled by following variables in the first kernel:
# - @var KDUMP_STDLOGLVL - logging level to standard error (console output)
# - @var KDUMP_SYSLOGLVL - logging level to syslog (by logger command)
# - @var KDUMP_KMSGLOGLVL - logging level to /dev/kmsg (only for boot-time)
#
# In the second kernel, kdump will use the rd.kdumploglvl option to set the
# log level in the above KDUMP_COMMANDLINE_APPEND.
# - @var rd.kdumploglvl - logging level to syslog (by logger command)
# - for example: add the rd.kdumploglvl=3 option to KDUMP_COMMANDLINE_APPEND
#
# Logging levels: no logging(0), error(1),warn(2),info(3),debug(4)
#
# KDUMP_STDLOGLVL=3
# KDUMP_SYSLOGLVL=0
# KDUMP_KMSGLOGLVL=0
