From 072ba380cefc7722c9442cc14a9c2810898c13ac Mon Sep 17 00:00:00 2001 From: Kefeng Wang Date: Tue, 16 May 2023 14:38:09 +0800 Subject: [PATCH] mm: page_alloc: move mirrored_kernelcore into mm_init.c Patch series "mm: page_alloc: misc cleanup and refactor", v2. This aims to reduce more space in page_alloc.c, also do some cleanup, no functional changes intended. This patch (of 13): Since commit 9420f89db2dd ("mm: move most of core MM initialization to mm/mm_init.c"), mirrored_kernelcore should be moved into mm_init.c, as most related codes are already there.
