------------------------------------------------------
Subject: kexec jump: clean up #ifdef and comments
From: Huang Ying <ying.huang@xxxxxxxxx>
Move if (kexec_image->preserve_context) { ... } into #ifdef
CONFIG_KEXEC_JUMP to make code looks cleaner.
Fix no longer correct comments of kernel_kexec().
