From f4fcbbe9a7fdf11305fea657202b954bdc2228ec Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Thu, 3 Nov 2005 14:41:19 +1100 Subject: powerpc: Merge remaining RTAS code This moves rtas-proc.c and rtas_flash.c into arch/powerpc/kernel, since cell wants them as well as pseries (and chrp can use rtas-proc.c too, at least in principle). rtas_fw.c is gone, with its bits moved into rtas_flash.c and rtas.c.

Revert to using two unsigned long longs (which is what ppc32 had originally). ppc64 orignally had two unsigned longs, but long long is the same size on 64 bit, so this should be ok there too.
