Pull perf tools fixes from Arnaldo Carvalho de Melo:

 - Fix double free in in the error path when opening perf.data from
   multiple files in a directory instead of from a single file

 - Sync the msr-index.h copy with the kernel sources

 - Fix error when printing 'weight' field in 'perf script'

 - Skip failing sigtrap test for arm+aarch64 in 'perf test'

 - Fix failure to use a cpu list for uncore events in hybrid systems,
   e.g. Intel Alder Lake
