-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.
