+
+When run "kexec" in powerpc board, the kexec has a limit that
+the kernel text and bss size must be less than 24M. But now
+some kernel size exceed the limit. So we need to change the limit,
+else will get the error log as below:

+In the kernel upstream commit 4ab65ba7a5cb

+__NR_kexec_file_load for arm has been defined to be 401.
+This results that even if kexec_file_load isn't implemented
