Subject: [GIT PULL] objtool changes for v5.10
Date: Tue, 13 Oct 2020 10:26:25 +0200 [thread overview]
Message-ID: <20201013082625.GA775379@gmail.com> (raw)
Linus,
Please pull the latest objtool/core git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git objtool-core-2020-10-13
# HEAD: 2486baae2cf6df73554144d0a4e40ae8809b54d4 objtool: Allow nested externs to enable BUILD_BUG()
objtool changes for v5.10:
- Most of the changes are cleanups and reorganization to make the objtool code
more arch-agnostic. This is in preparation for non-x86 support.
Fixes:
- KASAN fixes.
- Handle unreachable trap after call to noreturn functions better.
- Ignore unreachable fake jumps.
- Misc smaller fixes & cleanups.
Thanks,
Ingo
