Subject: [PATCH] mm: Move HOLES_IN_ZONE into mm
Date: Sat, 17 Apr 2021 15:59:46 +0800 [thread overview]
Message-ID: <20210417075946.181402-1-wangkefeng.wang@huawei.com> (raw)
commit a55749639dc1 ("ia64: drop marked broken DISCONTIGMEM and VIRTUAL_MEM_MAP")
drop VIRTUAL_MEM_MAP, so there is no need HOLES_IN_ZONE on ia64.
Also move HOLES_IN_ZONE into mm/Kconfig, select it if architecture needs
this feature.
