Use the general page fault accounting by passing regs into handle_mm_fault(). It naturally solve the issue of multiple page fault accounting when page fault retry happened. Remove the PERF_COUNT_SW_PAGE_FAULTS_[MAJ|MIN] perf events because it's now also done in handle_mm_fault(). Move the PERF_COUNT_SW_PAGE_FAULTS event higher before taking mmap_sem for the fault, then it'll match with the rest of the archs.
