The patch titled
Subject: x86/setup: use IS_ENABLED(CONFIG_KEXEC_CORE) instead of #ifdef
has been removed from the -mm tree. Its filename was

------------------------------------------------------
From: Jisheng Zhang <jszhang@xxxxxxxxxx>
Subject: x86/setup: use IS_ENABLED(CONFIG_KEXEC_CORE) instead of #ifdef
Replace the conditional compilation using "#ifdef CONFIG_KEXEC_CORE" by a
check for "IS_ENABLED(CONFIG_KEXEC_CORE)", to simplify the code and
increase compile coverage.
