Subject: [PATCH 2/4] use __cpuinitconst for x86
The patch probably doesn't change all instances where 'const' could
have been added as a result of the base structure changes, only where
the change has a real effect (the module loader doesn't enforce
read-only section attributes at present, so only built-in files make a
real difference).
