Subject: [PATCH 0/2] arm64: mm: fix kdump broken with ZONE_DMA reintroduced
Date: Sat, 26 Dec 2020 11:35:55 +0800 [thread overview]
Message-ID: <20201226033557.116251-1-chenzhou10@huawei.com> (raw)
If the memory reserved for crash dump kernel falled in ZONE_DMA32,
the devices in crash dump kernel need to use ZONE_DMA will alloc fail.
Fix this by reserving low memory in ZONE_DMA if CONFIG_ZONE_DMA is
enabled, otherwise, reserving in ZONE_DMA32.
Patch 1 updates the comments about the ZONE_DMA.
Patch 2 fix kdump broken.
