Subject: kexec jump: remove duplication of kexec_restart_prepare()
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=ca195b7f6da3d5dde0bb85a7c322d7de73352653;p=deliverable%2Flinux.git

kexec jump: remove duplication of kexec_restart_prepare()

Call kernel_restart_prepare() in kernel_kexec() instead of duplicating the
code.
