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.

[2] https://lore.kernel.org/netdev/14444103-d51b-0fb3-ee63-c3f182f0b546@molgen.mpg.de/

Fixes: fac54e2bfb5b ("x86/Kconfig: Select HAVE_ARCH_HUGE_VMALLOC with HAVE_ARCH_HUGE_VMAP")
