Subject: [PATCH v5 20/27] x86/setup: call hugetlb_bootmem_alloc early
Date: Fri, 28 Feb 2025 18:29:21 +0000 [thread overview]
Message-ID: <20250228182928.2645936-21-fvdl@google.com> (raw)
In-Reply-To: <20250228182928.2645936-1-fvdl@google.com>
Call hugetlb_bootmem_allloc in an earlier spot in setup, after
hugelb_cma_reserve. This will make vmemmap preinit of
the sections covered by the allocated hugetlb pages possible.
