[PATCH v2 0/4] RISC-V KVM PMU fix and selftest improvement

[Atish Patra <atishp@rivosinc.com>]

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.

Changes in v2:
- Initialized the local overflow irq variable to 0 indicate that it's not a
  allowed value. 
- Moved the introduction of argument option `n` to the last patch. 
- Link to v1: https://lore.kernel.org/r/20250226-kvm_pmu_improve-v1-0-74c058c2bf6d@rivosinc.com
