From 3d5ae6b69eacfac025021998d2ce159768edcfe1 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Tue, 25 Mar 2008 21:51:40 -0700 Subject: [PATCH] [SPARC64]: Fix sparse warnings in arch/sparc64/kernel/{cpu,setup}.c We create a local header file entry.h, under arch/sparc64/kernel/, that we can use to declare routines either defined in assembler or only invoked from assembler. As well as other data objects which are private to the inner sparc64 kernel arch code. Signed-off-by: David S.
