[PATCH v2 0/2] perf jevents: Enable build warnings

[John Garry]

Currently jevents builds without any complier warning flags enabled. So
use newly-defined HOSTCFLAGS, which comes from EXTRA_WARNINGS.

Changes for v2:
- Add Werror, Wall, and Wextra (James Clark suggestion)

Baseline is acme perf/core + mainline commit b94729919db2 ("perf jevents:
Free the sys_event_tables list after processing entries"):

680453e63302 perf jevents: Free the sys_event_tables list after processing entries
be8ecc57f180 (origin/perf/core) perf srcline: Use long-running addr2line per DSO
2b775152bbe8 perf tests vmlinux-kallsyms: Ignore hidden symbols

John Garry (2):
  perf jevents: Fix some would-be warnings
  perf jevents: Enable warnings through HOSTCFLAGS
