  	  motherboards), you can bypass it altogether and boot Linux directly
  	  from an SRM console; say Y here in order to do that. Note that you

  	default y if SMP
  	---help---
  	  The Wait for Interrupt (WTINT) PALcall attempts to place the CPU
  	  to sleep until the next interrupt.  This may reduce the power
  	  consumed, and the heat produced by the computer.  However, it has
  	  the side effect of making the cycle counter unreliable as a timing
  	  device across the sleep.
  
  	  For emulation under QEMU, definitely say Y here, as we have other
  	  mechanisms for measuring time than the cycle counter.
  
  	  For EV4 (but not LCA), EV5 and EV56 systems, or for systems running
  	  MILO, sleep mode is not supported so you might as well say N here.
  
  	  For SMP systems we cannot use the cycle counter for timing anyway,
  	  so you might as well say Y here.
  
  	  If unsure, say N.

  	  Process creation and other aspects of virtual memory management can
  	  be streamlined if we restrict the kernel to one PGD for all vmalloc
  	  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.

  	---help---
  	  This option allows the default printing mode to be set, and then
  	  possibly overridden by a boot command argument.
  
  	  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.

  	---help---
  	  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.
