Subject: kexec: fix for "Unhandled rela relocation: R_X86_64_PLT32" error
Date: Mon, 20 Aug 2018 12:00:31 +0100 [thread overview]
Message-ID: <cbf043a7-8e95-9486-3441-07ef8f2f86f5@googlemail.com> (raw)
In-Reply-To: <20180820083718.GZ4113@MiWiFi-R3L-srv>
In response to a change in binutils, change b21ebf2fb4cde1618915a97cc773e287ff49173e (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 in $SUBJECT when rebooting via kexec.
Fix this by replicating the change in kexec.
