Subject: [PATCH 0/7] perf: Intel PT and 64-bit AUX area size fixes

Hi

Here are some fixes.

I have taken the liberty of re-posting Marco Cavenati's patch from:

	https://lore.kernel.org/lkml/20240618110617.22626-1-cavenati.marco@gmail.com/

with updated commit suggested by Dave Hansen.


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

Marco Cavenati (1):
      perf/x86/intel/pt: Fix topa_entry base length
