Subject: [PATCH 0/4] RISC-V KVM PMU fix and selftest improvement

This series adds a fix for KVM PMU code and improves the pmu selftest
by allowing generating precise number of interrupts. It also provided
another additional option to the overflow test that allows user to
generate custom number of LCOFI interrupts.
