From ca48739e59df31d16c27dbcd9ea2ea61d7caa9fb Mon Sep 17 00:00:00 2001 From: Michael Kelley Date: Tue, 2 Mar 2021 13:38:13 -0800 Subject: Drivers: hv: vmbus: Move Hyper-V page allocator to arch neutral code The Hyper-V page allocator functions are implemented in an architecture neutral way. Move them into the architecture neutral VMbus module so a separate implementation for ARM64 is not needed. No functional change.
