tracing: Don't display trigger file for events that can't be enabled

2016-05-03T16:59:30Z

Currently register functions for events will be called through the 'reg' field of event class directly without any check when seting up triggers. Triggers for events that don't support register through debug fs (events under events/ftrace are for trace-cmd to read event format, and most of them don't have a register function except events/ftrace/functionx) can't be enabled at all, and an oops will be hit when setting up trigger for those events, so just not creating them is an easy way to avoid the oops.

kcov: don't profile branches in kcov

kcov: don't trace the code coverage code

2016-04-29T02:34:04Z

Kcov causes the compiler to add a call to __sanitizer_cov_trace_pc() in every basic block. Ftrace patches in a call to _mcount() to each function it has annotated. Letting these mechanisms annotate each other is a bad thing. Break the loop by adding 'notrace' to __sanitizer_cov_trace_pc() so that ftrace won't try to patch this code. This patch lets arm64 with KCOV and STACK_TRACER boot. Signed-off-by: James Morse Acked-by: Dmitry Vyukov Cc: Alexander Potapenko Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

kexec: export OFFSET(page.compound_head) to find out compound tail page

2016-04-29T02:34:04Z

PageAnon() always look at head page to check PAGE_MAPPING_ANON and tail page's page->mapping has just a poisoned data since commit 1c290f642101 ("mm: sanitize page->mapping for tail pages"). If makedumpfile checks page->mapping of a compound tail page to distinguish anonymous page as usual, it must fail in newer kernel. So it's necessary to export OFFSET(page.compound_head) to avoid checking compound tail pages. The problem is that unnecessary hugepages won't be removed from a dump file in kernels 4.5.x and later. This means that extra disk space would be consumed. It's a problem, but not critical. Signed-off-by: Atsushi Kumagai Acked-by: Dave Young Cc: "Eric W.
