Subject: [PATCH v3 25/29] mips: drop paging_init()
Date: Sun, 11 Jan 2026 10:20:59 +0200 [thread overview]
Message-ID: <20260111082105.290734-26-rppt@kernel.org> (raw)
In-Reply-To: <20260111082105.290734-1-rppt@kernel.org>
From: "Mike Rapoport (Microsoft)" <rppt@kernel•org>
All three variants of paging_init() on MIPS are wrappers for
pagetable_init().
Instead of having three identical wrappers, call pagetable_init() directly
from setup_arch() and remove the unnecessary paging_init() functions.
Signed-off-by: Mike Rapoport (Microsoft) <rppt@kernel•org>
