This the fix that I posted a couple of days ago after Andrew noted the
problem:
From: Christoph Lameter <clameter@sgi.com>
Subject: Allow override of definition for asm constant
MIPS has a different way of defining asm constants which causes troubles
for bounds.h generation (see also the Kbuild script).
Add a new per arch CONFIG variable
CONFIG_ASM_SYMBOL_PREFIX
which can be set to define an alternate header for asm constant definitions.
Use this for MIPS to make bounds determination work right.
