[PATCH v7 06/15] arm64, numa: rework numa_add_memblk()
From: David Daney <hidden>
Date: 2016-05-24 22:39:59
Also in:
linux-acpi, lkml
Subsystem:
arm64 port (aarch64 architecture), open firmware and flattened device tree, the rest · Maintainers:
Catalin Marinas, Will Deacon, Rob Herring, Saravana Kannan, Linus Torvalds
From: Hanjun Guo <redacted> Rework numa_add_memblk() to update the parameter "u64 size" to "u64 end", this will make it consistent with x86 and simplifies the arm64 ACPI NUMA code to be added later.
