From fdfdcfd504933ed06eb6b4c9df21eede0e213c3e Mon Sep 17 00:00:00 2001 From: Nicholas Piggin Date: Fri, 16 Sep 2022 14:07:55 +1000 Subject: [PATCH] powerpc/build: put sys_call_table in .data.rel.ro if RELOCATABLE Const function pointers by convention live in .data.rel.ro if they need to be relocated. Now that .data.rel.ro is linked into the read-only region, put them in the right section. This doesn't make much practical difference, but it will make the C conversion of sys_call_table a smaller change as far as linking goes.
