Subject: [PATCH v2 22/28] x86/mm: set ARCH_WANT_SPARSEMEM_VMEMMAP_PREINIT
Date: Wed, 29 Jan 2025 22:41:51 +0000 [thread overview]
Message-ID: <20250129224157.2046079-23-fvdl@google.com> (raw)
In-Reply-To: <20250129224157.2046079-1-fvdl@google.com>
Now that hugetlb bootmem pages are allocated earlier,
and available for section preinit (HVO-style), set
ARCH_WANT_SPARSEMEM_VMEMMAP_PREINIT for x86_64, so
that is can be done.
This enables pre-HVO on x86_64.
