Subject: [PATCH] mm: page_alloc: move mirrored_kernelcore into mm_init.c
References: bsc#1212886 (MM functional and performance backports) jsc#PED-5859
Git-commit: 072ba380cefc7722c9442cc14a9c2810898c13ac
Patch-mainline: v6.5-rc1
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.
