[PATCH v2 0/1] perf test: Add test for branch stack sampling
From: German Gomez

Hi,
While testing Anshuman Khandual's branch stack sampling ABI, and BRBE
driver ([1] and [2] respectively) I've been using this test to check the
consistency between arches (x86 and Arm64).
We will extend it with Arm64-specific tests once the BRBE driver has
been reviewed and merged, but for now I think this is generic enough to
also be useful for x86.
Thanks,
German

v2
- (Ian Rogers) Include C test program in the shell script.
- Drop references to Anshuman's ABI ext (FAULT_DATA and FAULT_INST).
We will track and update this later if necessary.
