Subject: [PATCH v2 7/7] powerpc/build: put sys_call_table in .data.rel.ro if RELOCATABLE

From: Nicholas Piggin <[email-masked]>
Date: Fri, 16 Sep 2022 14:07:55 +1000

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.
