Message-ID: <20070420050230.GA16420@localhost.localdomain>
Date: Fri, 20 Apr 2007 15:02:30 +1000

Subject: Cleanup mostly unused IOSPACE macros
Most architectures defined three macros, MK_IOSPACE_PFN(),
GET_IOSPACE() and GET_PFN() in pgtable.h. However, the only callers
of any of these macros are in Sparc specific code, either in
arch/sparc, arch/sparc64 or drivers/sbus.
This patch removes the redundant macros from all architectures except
sparc and sparc64.
