Subject: [PATCH bpf 1/4] x86: disable HAVE_ARCH_HUGE_VMALLOC
Date: Wed, 30 Mar 2022 15:56:39 -0700 [thread overview]
Message-ID: <20220330225642.1163897-2-song@kernel.org> (raw)
In-Reply-To: <20220330225642.1163897-1-song@kernel.org>
We cannot savely enable HAVE_ARCH_HUGE_VMALLOC for X86_64 yet. See [1]
and [2] for more details. Disable it for now.
