Subject: [PATCH 25/28] x86: don't reserve hugetlb memory in setup_arch()
Date: Sun, 28 Dec 2025 14:39:55 +0200 [thread overview]
Message-ID: <20251228124001.3624742-26-rppt@kernel.org> (raw)
In-Reply-To: <20251228124001.3624742-1-rppt@kernel.org>
From: "Mike Rapoport (Microsoft)" <rppt@kernel.org>
Commit 665eaf313314 ("x86/setup: call hugetlb_bootmem_alloc early")
added an early call to hugetlb_bootmem_alloc() to setup_arch() to allow
HVO style pre-initialization of vmemmap on x86.
With the ordering of hugetlb reservation vs memory map initiaization
sorted out in core MM this no longer needs to be an architecture specific
quirk.
Drop the call to hugetlb_bootmem_alloc() from x86::setup_arch().
