-Subject: [PATCH] arm64: mm: reserve CMA and crashkernel in ZONE_DMA32
-
-commit bff3b04460a80f425442fe8e5c6ee8c3ebef611f upstream.
-
-With the introduction of ZONE_DMA in arm64 we moved the default CMA and
-crashkernel reservation into that area. This caused a regression on big
-machines that need big CMA and crashkernel reservations. Note that
-ZONE_DMA is only 1GB big.
-
-Restore the previous behavior as the wide majority of devices are OK
-with reserving these in ZONE_DMA32. The ones that need them in ZONE_DMA
-will configure it explicitly.
-
-Fixes: 1a8e1cef7603 ("arm64: use both ZONE_DMA and ZONE_DMA32")
