From a9f4a6e92b3b319296fb078da2615f618f6cd80c Mon Sep 17 00:00:00 2001 From: Sean Christopherson Date: Thu, 11 Nov 2021 02:07:38 +0000 Subject: [PATCH] perf: Drop guest callback (un)register stubs Drop perf's stubs for (un)registering guest callbacks now that KVM registration of callbacks is hidden behind GUEST_PERF_EVENTS=y. The only other user is x86 XEN_PV, and x86 unconditionally selects PERF_EVENTS. No functional change intended.
