I have enabled the kexec in the kernel configuration, when I ran the
kexec I get the following error:

# ./kexec -l ./bzImage
kexec_load failed: Function not implemented
entry       = 0x977b8 flags = 0
nr_segments = 3
segment[0].buf   = 0x8071600
segment[0].bufsz = 2a00
segment[0].mem   = 0x3000
segment[0].memsz = 3000
segment[1].buf   = 0x806a550
segment[1].bufsz = 7060
segment[1].mem   = 0x97000
segment[1].memsz = 9000
segment[2].buf   = 0xb7c3aa08
segment[2].bufsz = 1d7eb8
segment[2].mem   = 0x100000
segment[2].memsz = 1d8000
