Another compile problem on sparc64

Another compile problem on sparc64

[Marcel Holtmann]

Hi,

my compile problem with arch/sparc64/kernel/process.o is gone, but I get
another compile problem with the latest 2.6 Bitkeeper sources:

  CC      arch/sparc64/mm/init.o
arch/sparc64/mm/init.c: In function `check_pgt_cache':
arch/sparc64/mm/init.c:107: warning: use of cast expressions as lvalues is deprecated

My compiler is still the latest GCC from Debian Sid:

gcc (GCC) 3.3.3 (Debian 20040321)
Copyright (C) 2003 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO

You could have killed all of this by just temporarily removing
the "-Werror" that gets added in the arch/sparc64/ Makefiles :-)

This latest one only happens on uniprocessor builds, which is why
I didn't catch it.  Only recent debian unstable updates of gcc started
to emit these warnings fwiw...

Anyways, here's the fix, I'll push it off to Linus.
