When starting a new torture run while an old one is still running, both
qemu processes can be outputting to the same console.out file. This can
cause quite a bit of confusion, so this commit checks for this situation,
which is normally indicated by nul bytes in the console output. Yes,
if your new run uses up an exact number of blocks of the file, this
check will be ineffective, but the odds are not bad.

This commit specifies offstack cpumasks in TREE07 in order to catch
references to unallocated cpumask_var_t variables.

Setting CONFIG_MAXSMP=y causes cpumasks to be moved offstack, which
introduces the possibility of NULL cpumask_var_t pointers. This commit
therefore enables CONFIG_MAXSMP=y in TREE01 to increase test coverage.
However, because CONFIG_MAXSMP=y implies 8192 CPUs, we need to use
the maxcpus= boot parameter to limit the number of CPUs to something
reasonable, which in turn requires updating the scripts to handle this.

The current set of tests covers only cases where either all possible CPUs
are nohz_full= CPUs or none of them are. Because there have been some
recent bug escapes in cases where only some of the CPUs are nohz_full=
CPUs, this commit add a configuration where only half of the CPUs are
nohz_full= CPUs.

Some of the scripts encode a default /bin/sh shell. On systems which use
dash as default shell, these scripts fail as they are bash scripts. I
encountered this while testing the sprintf() changes on a Debian system
where dash is the default shell.
This commit changes all such uses to use bash explicitly.

If ffs-test is used with a kernel prior to 3.14, which do not
support the new descriptors format, it will fail when trying to
write the descriptors. Add a function that converts the new
descriptors to the legacy ones and use it to retry writing the
descriptors using the legacy format.
Also add “-l” flag to ffs-test which will cause the tool to
never try the new format and instead immediatelly try the
legacy one. This should be useful to test whether parsing
of the old format still works on given 3.14+ kernel.

Since commit [ac8dde11: “Add flags to descriptors block”] functionfs
supports a new, more powerful and extensible, descriptor format.
Since ffs-test is probably the first thing users of the functionfs
interface see when they start writing functionfs user space daemons,
convert it to use the new format thus promoting it.

As we run "perf c2c" on more applications, we noticed we're missing
significant samples from a common customer's application. Looking at
the /proc/<pid>/maps file for the app, we see "rwxs" and "rwxp"
permissions on many of the shared memory & heap regions, and on all the
thread stacks.
Because those regions have the "x" bit set, perf marks them with a
MAP_FUNCTION type. Hence ip_resolve_data() never finds load or store
events coming from them.
We fixed this by re-calling thread__find_addr_location with
MAP__FUNCTION in the case where map is NULL as a last ditch effort to
map the sample before giving up and dropping it.

The hist_browser__show_callchain() and friends don't need to be that
complex. They're splitted in 3 pieces - one for traversing top-level
tree, other one for special casing first chains in the top-level
entries, and last one for recursive traversing inner trees. It led to
code duplication and unnecessary complexity IMHO.
Simplify the function and consolidate the logic into a single function
- it can recursively call itself. A little difference in printing
callchains in top-level tree can be handled with a small change.
It should have no functional change.

Since the strlist__add doesn't involves any IO, the failure reason must
be ENOMEM or EINVAL, moreover this is just a debug message, we don't
need to show the error string.
And also, if get_probe_trace_command_rawlist() returns NULL, it doesn't
mean the rawlist is empty, there is an error. So caller must use
-ENOMEM for the error.

Current perf report -g/--call-graph option parser requires for option
argument having following order:
type,min_percent[,print_limit],order,key
But sometimes it's annoying to type all even if one just wants to change
the "order" or "key" setting.
This patch fixes it to remove the ordering restriction so that one can
use just "-g caller", for instance. The only remaining restriction is
that the "print_limit" always comes after the "min_percent".
