Subject: [PATCH bpf] selftests/bpf: verifier_arena: fix mmap address for arm64
Date: Fri, 22 Mar 2024 13:35:52 +0000	[thread overview]
Message-ID: <20240322133552.70681-1-puranjay12@gmail.com> (raw)

The arena_list selftest uses (1ull << 32) in the mmap address
computation for arm64. Use the same in the verifier_arena selftest.

This makes the selftest pass for arm64 on the CI[1].
