Subject: mm: page_alloc: move mirrored_kernelcore into mm_init.c
Date: Tue, 16 May 2023 14:38:09 +0800
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.
