From: Mingli Yu <[email protected]> In response to a change in binutils, commit b21ebf2fb4c (x86: Treat R_X86_64_PLT32 as R_X86_64_PC32) was applied to the linux kernel during the 4.16 development cycle and has since been backported to earlier stable kernel series. The change results in the failure message as below when rebooting via kexec. # kexec -l /boot/bzImage --append="console=ttyS0,115200 root=/dev/sda1" Unhandled rela relocation: R_X86_64_PLT32
Fix this by replicating the change in kexec.
