[PATCH v2 02/15] ARM: mark const init data with __initconst instead of __initdata
From: Uwe Kleine-KÃnig
Date: Fri Mar 30 2012 - 16:05:53 EST
As long as there is no other non-const variable marked __initdata in the
same compilation unit it doesn't hurt. If there were one however
compilation would fail with
error: $variablename causes a section type conflict
because a section containing const variables is marked read only and so
cannot contain non-const variables.
