perf script python: Fix export-to-postgresql.py occasional failure

2018-10-18T07:13:21+00:00

commit 25e11700b54c7b6b5ebfc4361981dae12299557b upstream.

Occasional export failures were found to be caused by truncating 64-bit
pointers to 32-bits. Fix by explicitly setting types for all ctype
arguments and results.

Now that eagerfpu= is gone, remove it from the docs and some
comments.  Also sync the changes to tools/.

perf probe powerpc: Ignore SyS symbols irrespective of endianness

[ Upstream commit fa694160cca6dbba17c57dc7efec5f93feaf8795 ]

This makes sure that the SyS symbols are ignored for any powerpc system,
not just the big endian ones.

perf evsel: Fix potential null pointer dereference in perf_evsel__new_idx()

[ Upstream commit fd8d2702791a970c751f8b526a17d8e725a05b46 ]

If evsel is NULL, we should return NULL to avoid a NULL pointer
dereference a bit later in the code.

tools/vm/slabinfo.c: fix sign-compare warning

2018-10-10T06:53:20+00:00

[ Upstream commit 904506562e0856f2535d876407d087c9459d345b ]

Currently we get the following compiler warning:

    slabinfo.c:854:22: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
       if (s->object_size < min_objsize)
                          ^

due to the mismatch of signed/unsigned comparison.  ->object_size and
->slab_size are never expected to be negative, so let's define them as
unsigned int.

selftest: timers: Tweak raw_skew to SKIP when ADJ_OFFSET/other clock adjustments are in progress

2018-09-26T06:36:39+00:00

[ Upstream commit 1416270f4a1ae83ea84156ceba19a66a8f88be1f ]

In the past we've warned when ADJ_OFFSET was in progress, usually
caused by ntpd or some other time adjusting daemon running in non
steady sate, which can cause the skew calculations to be
incorrect.

Thus, this patch checks to see if the clock was being adjusted
when we fail so that we don't cause false negatives.
