[PATCH 0/2] perf tests: Check for ARM [vectors] page

[Florian Fainelli]

Hi all,

I just painfully learned that perf would segfault when
CONFIG_KUSER_HELPERS is disabled because it unconditionally makes use of
it. This patch series adds an ARM test for that by leveraging the
existing find_vdso_map() function and making it more generic and capable
of location any map within /proc/self/maps.

Florian Fainelli (2):
  perf tools: Make find_vdso_map() more modular
  perf tests: Add a test for the ARM 32-bit [vectors] page
