Subject: [PATCH 1/3] perf, tools: Add support for perf list vendor
From: Andi Kleen <ak@...ux.intel.com>
Add an argument to perf list to only list vendor events. To be used
for the command line completion script. This requires adding
a new flag to the alias structure.
v2: Rename to perf list vendor/model/cpu-model
Signed-off-by: Andi Kleen <ak@...ux.intel.com>

. If none of the above is matched, it will apply the supplied glob to all
events, printing the ones that match.
