From b54816eff272324320c490d62dc36b27d2838732 Mon Sep 17 00:00:00 2001

Subject: [PATCH] kexec/arm: undefine __NR_kexec_file_load for arm
In the kernel upstream commit 4ab65ba7a5cb
("ARM: add kexec_file_load system call number"),
__NR_kexec_file_load for arm has been defined to be 401.
This results that even if kexec_file_load isn't implemented
for arm but the function is_kexec_file_load_implemented()
will still return true. So undef __NR_kexec_file_load for
arm architecture.
Upstream-Status: Backport
[https://git.kernel.org/pub/scm/utils/kernel/kexec/kexec-tools.git/commit/kexec/kexec-syscall.h?id=b54816eff272324320c490d62dc36b27d2838732]
