Date: Thu, 26 Aug 2021 22:09:52 +0800 [thread overview]
Message-ID: <20210826220952.77a68a9e@xhacker> (raw)
From: Jisheng Zhang <jszhang@kernel.org>
Enable BUILDTIME_TABLE_SORT to sort the exception table at build time
then move exception table to RO_DATA segment.
Since v1:
- Only enable BUILDTIME_TABLE_SORT for MMU. Thank Palmer for catching
tinyconfig case.
