[PATCH 1/4] introduce __cpuinitconst

From: Jan Beulich
Date: Fri Jan 11 2008 - 03:56:16 EST


The patch 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).
