If a hist entry doesn't have symbol information, compare it with its

This can lead to an undesired result like an overhead exceeds 100%

Pull perf/core improvements and refactorings from Arnaldo Carvalho de Melo:
New features:
. In perf timechart:
- Add backtrace support to CPU info
. Print pid along the name
. Add support for CPU topology
. Add new option --highlight'ing threads, be it by name or,
if a numeric value is provided, that run more than given duration.
From Stanislav Fomichev.
Refactorings:
. Rename some struct DSO binary_type related members and methods,
to clarify its purpose and need for differentiation from symtab_type,
i.e. one is about the files .text, CFI, etc, i.e. its binary contents,
and the other is about where the symbol table came from.
. Convert to new topic libraries, starting with an API one (sysfs, debugfs,
etc), renaming liblk in the process, from Borislav Petkov.
. Get rid of some more panic() like error handling in libtraceevent,
from Namhyung Kim.

It was called "data_type", but in this context "data" is way too vague,
it could mean the "data" ELF segment, or something else.
Since we have dso__read_binary_type_filename() and the values this field
receives are all DSO__BINARY_TYPE_<FOO> we may as well call it
"binary_type" for consistency sake.
It also seems more appropriate since it determines if we can do
operations like annotation and DWARF unwinding, that needs more than
just the symtab, requiring access to ELF text segments, CFI ELF
sections, etc.

Vince Weaver reports that, on all architectures apart from ARM,
PERF_EVENT_IOC_PERIOD doesn't actually update the period until the next
event fires. This is counter-intuitive behaviour and is better dealt
with in the core code.
This patch ensures that the period is forcefully reset when dealing with
such a request in the core code. A subsequent patch removes the
equivalent hack from the ARM back-end.

Move debugfs.* to api/fs/. We have a common tools/lib/api/ place where
the Makefile lives and then we place the headers in subdirs.
For example, all the fs-related stuff goes to tools/lib/api/fs/ from
which we get libapikfs.a (acme got almost the naming he wanted :-)) and
we link it into the tools which need it - in this case perf and
tools/vm/page-types.
acme:
"Looking at the implementation, I think some tools can even link
directly to the .o files, avoiding the .a file altogether.
But that is just an optimization/finer granularity tools/lib/
cherrypicking that toolers can make use of."

For NUMA systems, initializing the blk-mq layer and using per node hctx.
We initialize submit queues to 1, while blk-mq nr_hw_queues is
initialized to the number of NUMA nodes.
This makes the null_init_hctx function overwrite memory outside of what
it allocated. In my case it lead to writing garbage into struct

selinux: process labeled IPsec TCP SYN-ACK packets properly in selinux_ip_postroute()
selinux: look for IPsec labels on both inbound and outbound packets

This reverts commit 102aefdda4.
Tom London reports that it causes sync() to hang on Fedora rawhide:
https://bugzilla.redhat.com/show_bug.cgi?id=1033965
and Josh Boyer bisected it down to this commit. Reverting the commit in
the rawhide kernel fixes the problem.
Eric Paris root-caused it to incorrect subtype matching in that commit
breaking fuse, and has a tentative patch, but by now we're better off
retrying this in 3.14 rather than playing with it any more.

deadlock due to a shared workqueue in the delay target, fix to
initialize read-only module parameters that are used to export metrics
for dm stats and dm bufio.

reference counting fixes for the space map btree that is used by the

A small set of driver fixes plus one larger core change which changes
the way we check to see if we're using DT so that there aren't any races
between deciding we're using DT and the regulator subsystem noticing.
This makes the new support for substituting a dummy regulator and
optional regulators work a lot better on DT systems since it ensures
that we don't trigger probe deferral when we shouldn't which was causing
bugs in clients.

An old array block could have its reference count decremented below
zero when it is being replaced in the btree by a new array block.
The fix is to increment the old ablock's reference count just before
inserting a new ablock into the btree.

The old behaviour, returning -EINVAL if a ref_count of 0 would be
decremented, was removed in commit f722063 ("dm space map: optimise
sm_ll_dec and sm_ll_inc"). To fix this regression we return an error
code from the mutator function pointer passed to sm_ll_mutate() and have
dec_ref_count() return -EINVAL if the old ref_count is 0.
Add a DMERR to reflect the potential seriousness of this error.
Also, add missing dm_tm_unlock() to sm_ll_mutate()'s error path.
With this fix the following dmts regression test now passes:
dmtest run --suite cache -n /metadata_use_kernel/
The next patch fixes the higher-level dm-array code that exposed this
regression.
