This change is located in arch/arm64 folder, I have pinged arm64
maintainer to consider merging this patchset. Not sure if they are
still thinking, or ignore this.

Hi Catalin, Will,

Ping again!

Do you have plan to accept this patchset? It's very important for
crashkernel setting on arm64 with a simple and default syntax.

Thanks
