+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]
