From: Andi Kleen <a...@linux.intel.com>
Make the 'perf list' glob matching for vendor events case insensitive.
This allows to use the upper case vendor events with perf list too.
Now the following works:
% perf list LONGEST_LAT
...
cache:
longest_lat_cache.miss
[Core-originated cacheable demand requests missed LLC]
longest_lat_cache.reference
[Core-originated cacheable demand requests that refer to LLC]
