[failures] arm-use-is_enabledconfig_kexec_core-instead-of-ifdef.patch removed from -mm tree

[akpm]

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

This patch was dropped because it had testing failures

------------------------------------------------------
From: Jisheng Zhang <jszhang@kernel.org>
Subject: arm: 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.

Removed from the linux-next akpm-current tree as well.

I clearly need to remember to read all my email before replying :-)
