+	  Process creation and other aspects of virtual memory management can

+	  allocations.  This equates to about 8GB.
+
+	  Under normal circumstances, this is so far and above what is needed
+	  as to be laughable.  However, there are certain applications (such
+	  as benchmark-grade in-kernel web serving) that can make use of as
+	  much vmalloc space as is available.
+
+	  Say N unless you know you need gobs and gobs of vmalloc space.

+
+	  For example, if one wanted the option of printing verbose
+	  machine checks, but wanted the default to be as if verbose
+	  machine check printing was turned off, then one would choose
+	  the printing mode to be 0. Then, upon reboot, one could add
+	  the boot command line "verbose_mcheck=1" to get the normal
+	  verbose machine check printing, or "verbose_mcheck=2" to get
+	  the maximum information available.
+
+	  Take the default (1) unless you want more control or more info.

+	  SRM environment variables (those which have a name) and also
+	  to all others (by their internal number).
+

+
+	  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.
