| 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 |
