Adrian Hunter (6):
perf/x86/intel/pt: Fix a topa_entry base address calculation
perf/x86/intel/pt: Fix pt_topa_entry_for_page() address calculation
perf: Fix perf_aux_size() for greater-than 32-bit size

perf: Fix default aux_watermark calculation
perf: Make rb_alloc_aux() return an error immediately if nr_pages <= 0
