Alexander Shishkin b34abf24f2 perf, pt, coresight: Fix address filters for vmas with non-zero offset ... [ Upstream commit c60f83b813 ] Currently, the address range calculation for file-based filters works as long as the vma that maps the matching part of the object file starts from offset zero into the file (vm_pgoff==0). Otherwise, the resulting filter range would be off by vm_pgoff pages. Another related problem is that in case of a partially matching vma, that is, a vma that matches part of a filter region, the filter range size wouldn't be adjusted. Fix the arithmetics around address filter range calculations, taking into account vma offset, so that the entire calculation is done before the filter configuration is passed to the PMU drivers instead of having those drivers do the final bit of arithmetics. Based on the patch by Adrian Hunter <adrian.hunter.intel.com>.
