      atyfb: Fix bootup hangs on sparc64. · 09798eb9
      David S. Miller 提交于
      After commit 25edd694 ("sparc64: Get
      rid of indirect p1275 PROM call buffer.")  we can't pass virtual
      addresses >4GB to PROM calls.
      
      Largely this is never necessary in drivers because we have a copy of
      the entire PROM device tree in the kernel and a set of of_*()
      interfaces to access it.
      
      Unfortunately there were some lingering prom calls in the atyfb
      driver, in particular prom_finddevice() was being called with an
      on-stack address which could be anywhere.
      
      This code is actually probing for information we already have, the
      PROM choosen console output device is stored in of_console_device so
      all of this nasty code consolidates into a one-line comparison.
      
      Next we have some prom_getintdefault() calls which are trivially
      transformed into the equivalent of_getintprop_default().
      
      Special thanks to Fabio, who figured out exactly where the bootup
      was hanging.  That made this bug trivial to fix.
