[PATCH v13 0/8] support reserving crashkernel above 4G on arm64 kdump

2020-10-31 Thread Chen Zhou
There are following issues in arm64 kdump: 1. We use crashkernel=X to reserve crashkernel below 4G, which will fail when there is no enough low memory. 2. If reserving crashkernel above 4G, in this case, crash dump kernel will boot failure because there is no low memory available for allocation.
