Help text

If you enable this option, a subdirectory inside /proc called /proc/srm_environment will give you access to the all important SRM environment variables (those which have a name) and also to all others (by their internal number).

SRM is something like a BIOS for Alpha machines. There are some other such BIOSes, like AlphaBIOS, which this driver cannot support (hey, that's not SRM!).

Despite the fact that this driver doesn't work on all Alphas (but only on those which have SRM as their firmware), it's save to build it even if your particular machine doesn't know about SRM (or if you intend to compile a generic kernel). It will simply not create those subdirectory in /proc (and give you some warning, of course).

This driver is also available as a module and will be called srm_env then.
