Please don't make up random prefixes. This should really be "x86/pmu". >From Documentation/process/maintainer-kvm-x86.rst: Shortlog ~~~~~~~~ The preferred prefix format is ``KVM: <topic>:``, where ``<topic>`` is one of:: - x86 - x86/mmu - x86/pmu - x86/xen - selftests - SVM - nSVM - VMX - nVMX ... New topics do occasionally pop up, but please start an on-list discussion if you want to propose introducing a new topic, i.e. don't go rogue.
