Subject: [PATCH v2 0/7] powerpc: build / linker improvements
Date: Fri, 16 Sep 2022 14:07:48 +1000 [thread overview]
Message-ID: <20220916040755.2398112-1-npiggin@gmail.com> (raw)
This series is mainly about moving more things out of writable and
executable memory, and slightly moving the linker script in the
direction of the binutils ld internal linker script as we do.
Thanks,
Nick
Since v1:
- Move sys_call_table data.rel.ro patch to the end.
- And fix the changelog in that patch, the relocations were a red herring.
- Update the changelog in the __end_rodata patch.
- Align __end_rodata to strict align size.
Nicholas Piggin (7):
powerpc: move __end_rodata to cover arch read-only sections
