[PATCH v2 0/3] Additional refactoring of Hyper-V arch specific code

From: Michael Kelley
Date: Wed Jul 14 2021 - 14:35:13 EST


This patch set moves additional Hyper-V code under arch/x86 into
arch-neutral hv_common.c where it can be shared by x86 and
and ARM64 implementations. The move reduces the overall lines
of code across both architectures, and removes code under
arch/ that isn't really architecture-specific.

The code is moved into hv_common.c because it must be
built-in to the kernel image, and not be part of a module.

No functional changes are intended.

Changes in v2:
* Fixed problem when building with CONFIG_HYPERV=n
(reported by kernel test robot <lkp@xxxxxxxxx>)

Drivers: hv: Add arch independent default functions for some Hyper-V
handlers
Drivers: hv: Move Hyper-V misc functionality to arch-neutral code
