From 9a4fc4eaf111ca960c9f524b850598e9dbc9697f Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Thu, 10 Jul 2014 19:34:31 +1000 Subject: powerpc/kvm: Create proper names for the kvm_host_state PMU fields We have two arrays in kvm_host_state that contain register values for the PMU. Currently we only create an asm-offsets symbol for the base of the arrays, and do the array offset in the assembly code. Creating an asm-offsets symbol for each field individually makes the code much nicer to read, particularly for the MMCRx/SIxR/SDAR fields, and might have helped us notice the recent double restore bug we had in this code.
