Subject: [PATCH v3 0/3] arm64/riscv: Add support for crashkernel CMA reservation

Add support for crashkernel CMA reservation for arm64 and riscv.

By the way, exclude crash kernel memory in crash core to
avoid duplication.

Changs in v3:
- Exclude crash kernel memory in crash core as Mike suggested.
- Add acked-by.

Jinjie Ruan (3):
  crash: Exclude crash kernel memory in crash core
  arm64: kexec: Add support for crashkernel CMA reservation
  riscv: kexec: Add support for crashkernel CMA reservation
