From cf00a8d18b9a1c2d55b2728e89125c234e821db5 Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Mon, 31 Oct 2005 13:07:02 +1100 Subject: powerpc: Fix bug arising from having multiple memory_limit variables We had a static memory_limit in prom.c, and then another one defined in setup_64.c and used in numa.c, which resulted in the kernel crashing when mem=xxx was given on the command line. This puts the declaration in system.h and the definition in mem.c. This also moves the definition of tce_alloc_start/end out of setup_64.c.
