Tom will have a look at the fix but the below code is wrong:
> -module_param(allow_kdump, int, 0);
> +module_param(allow_kdump, int, 1);
> MODULE_PARM_DESC(allow_kdump, "Start a kernel dump after NMI occurs");
the syntax is: #define module_param(name, type, perm)
perm sets the visibility in sysfs: 000 means it's not there,
read bits mean it's readable, write bits mean it's writable.
perm is not the default value for the integer but a file permission attribute.
