[PATCH 1/4] tools lib traceevent: Silence compiler warning on 32bit build

The gcc complains about casting a pointer to unsigned long long directly:

[PATCH 2/4] perf ui: Make --stdio default when TUI is not supported

[Arnaldo Carvalho de Melo]

From: Namhyung Kim <namhyung@gmail.com>

The commit dc41b9b8f02db ("perf ui: Change fallback policy of
setup_browser") changed default behavior of the function but missed
setting the use_browser variable to 0 accidently. So perf report ends up
doing nothing in such cases. Fix it.

[PATCH 3/4] perf tools: Convert critical messages to ui__error()

[Arnaldo Carvalho de Melo]

From: Namhyung Kim <namhyung@gmail.com>

There were places where use ui__warning (or even fprintf) to show
critical messages. This patch converts them to ui__error so that the
front-end code can implement appropriate behavior.

[PATCH 4/4] perf annotate browser: The idx_asm field should be used in asm only view

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

When hide_src_view is true we can't use browser_disasm_line->idx, that
takes into account also non asm lines, we must use browser_disasm_line->idx_asm
instead, otherwise we may end up with an index after the number of
entries, oops, fix it.
