Subject: [PATCH v2 03/13] hexagon: move initialization of init_mm.context init to paging_init()
Date: Thu, 13 Mar 2025 15:49:53 +0200	[thread overview]
Message-ID: <20250313135003.836600-4-rppt@kernel.org> (raw)
In-Reply-To: <20250313135003.836600-1-rppt@kernel.org>

From: "Mike Rapoport (Microsoft)" <rppt@kernel.org>

This will help with pulling out memblock_free_all() to the generic
code and reducing code duplication in arch::mem_init().

Signed-off-by: Mike Rapoport (Microsoft) <rppt@kernel.org>
