perf symbols: Allow loading kallsyms without considering kcore files
Before the support for using /proc/kcore was introduced, the kallsyms routines used /proc/modules and the first 'perf test' entry expected finding maps for each module in the system, which is not the case with the kcore code. Provide a way to ignore kcore files so that the test can have its expectations met. Improving the test to cover kcore files as well needs to be done.

perf jit: memset() variable 'st' using the correct size
The current code is memsetting the 'struct stat' variable 'st' with the size of
'stat' (which turns out to be 1 byte) rather than the size of variable 'sz'.
Committer notes:
sizeof(function) isn't valid, the result depends on the compiler used, with
gcc, enabling pedantic warnings we get:
$ cat sizeof_function.c
#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>
#include <stdio.h>
int main(void)
{
printf("sizeof(stat)=%zd, stat=%p\n", sizeof(stat), stat);
return 0;
}
$ readelf -sW sizeof_function | grep -w stat
49: 0000000000400630 16 FUNC WEAK HIDDEN 13 stat
$ cc -pedantic sizeof_function.c -o sizeof_function
sizeof_function.c: In function ‘main’:
sizeof_function.c:8:46: warning: invalid application of ‘sizeof’ to a function type [-Wpointer-arith]
printf("sizeof(stat)=%zd, stat=%p\n", sizeof(stat), stat);
^
$ ./sizeof_function
sizeof(stat)=1, stat=0x400630
$
Standard C, section 6.5.3.4:
"The sizeof operator shall not be applied to an expression that has function
type or an incomplete type, to the parenthesized name of such a type,
or to an expression that designates a bit-field member."

perf script: Fix postgresql ubuntu install instructions
The current instructions for setting up an Ubuntu system for using the
export-to-postgresql.py script are incorrect.
The instructions in the script have been updated to work on newer
versions of ubuntu.
-Add missing dependencies to apt-get command:
python-pyside.qtsql, libqt4-sql-psql
-Add '-s' option to createuser command to force the user to be a
superuser since the command doesn't prompt as indicated in the
current instructions.
Tested on: Ubuntu 14.04, Ubuntu 16.04(beta)

perf trace: Fix build when DWARF unwind isn't available
The variable is initialized and then conditionally set to a different
value, but not used when DWARF unwinding is not available, bummer, write
1000 times: "Run make -C tools/perf build-test"...
builtin-trace.c: In function ‘cmd_trace’:
builtin-trace.c:3112:6: error: variable ‘max_stack_user_set’ set but not
used [-Werror=unused-but-set-variable]
bool max_stack_user_set = true;
^
cc1: all warnings being treated as err
Fix it by marking it as __maybe_unused.

perf/core improvements:
User visible:
- Wire the callchain unwinding "max-stack" know to 'perf script --max-stack',
allowing to limit the depth of callchains, possibly reducing processing
time (Arnaldo Carvalho de Melo)
- Ditto for 'perf trace --max-stack' (Arnaldo Carvalho de Melo)
- Introduce a --min-stack filter for 'perf trace', to show syscalls that
had a userspace callchain leading to it at least min-stack deep (Arnaldo Carvalho de Melo)
- Make 'perf trace' work with multiple threads and the --duration filter,
i.e. do not print the start of an interrupted syscall followed by ...
to print interrupts from other threads, as we need to wait the sys_exit
syscall tracepoint to calculate the duration, duh. (Arnaldo Carvalho de Melo)
System wide --duration now works as expected:
[root@jouet ~]# trace --duration 100

Pull block fixes from Jens Axboe:
"A few fixes for the current series. This contains:
- Two fixes for NVMe:
One fixes a reset race that can be triggered by repeated
insert/removal of the module.
The other fixes an issue on some platforms, where we get probe
timeouts since legacy interrupts isn't working. This used not to
be a problem since we had the worker thread poll for completions,
but since that was killed off, it means those poor souls can't
successfully probe their NVMe device. Use a proper IRQ check and
probe (msi-x -> msi ->legacy), like most other drivers to work
around this. Both from Keith.
- A loop corruption issue with offset in iters, from Ming Lei.
- A fix for not having the partition stat per cpu ref count
initialized before sending out the KOBJ_ADD, which could cause user
space to access the counter prior to initialization. Also from
Ming Lei.
- A fix for using the wrong congestion state, from Kaixu Xia"

perf trace: Do not print interrupted syscalls when using --duration
With multiple threads, e.g. a system wide trace session, and one syscall is
midway in a thread and another thread starts another syscall we must print the
start of the interrupted syscall followed by ..., but that can't be done that
way when we use the --duration filter, as we have to wait for the syscall exit
to calculate the duration and decide if it should be filtered, so we have to
disable the interrupted logic and only print at syscall exit, duh.
Before:
# trace --duration 100

block: loop: fix filesystem corruption in case of aio/dio
Starting from commit e36f620428(block: split bios to max possible length),
block core starts to split bio in the middle of bvec.
Unfortunately loop dio/aio doesn't consider this situation, and
always treat 'iter.iov_offset' as zero. Then filesystem corruption
is observed.
This patch figures out the offset of the base bvevc via
'bio->bi_iter.bi_bvec_done' and fixes the issue by passing the offset
to iov iterator.
