Subject: [PATCH -next] objtool: use arch_jump_destination in read_intra_function_calls
Date:   Thu, 18 Aug 2022 09:45:53 +0800
Message-ID: <20220818014553.220261-1-chenzhongjin@huawei.com>

Precedence: bulk

arch_jump_destination() is used instead of offset + len + immediate
for jump destination.
But in read_intra_function_calls it didn't get changed.
It can make trouble for other arches development such as arm or ppc.
Fix it.
