Subject: [PATCH perf/core 0/3] perf-probe: Fix offline module and cross-arch support

Hello,

This series fixes some issues on offline module/cross-arch
probe support. While I was debuging arm32 kernel with
cross-arch perf-probe, I found several issues.

- perf-probe didn't show correct probe definition on
  gcc-generated symbols (on both of kernel and module).
- perf-probe didn't show available functions for offline
  module even if full path of the module was given.

This series fixes those issues.
