From f3c5e63c3690fc64e5a7a2b3e4f9f5ff1fa25584 Mon Sep 17 00:00:00 2001 From: Michael Kelley Date: Tue, 2 Mar 2021 13:38:15 -0800 Subject: Drivers: hv: Redo Hyper-V synthetic MSR get/set functions Current code defines a separate get and set macro for each Hyper-V synthetic MSR used by the VMbus driver. Furthermore, the get macro can't be converted to a standard function because the second argument is modified in place, which is somewhat bad form. Redo this by providing a single get and a single set function that take a parameter specifying the MSR to be operated on. Fixup usage of the get function. Calling locations are no more complex than before, but the code under arch/x86 and the upcoming code under arch/arm64 is significantly simplified. Also standardize the names of Hyper-V synthetic MSRs that are architecture neutral. But keep the old x86-specific names as aliases that can be removed later when all references (particularly in KVM code) have been cleaned up in a separate patch series. No functional change.
