Running the command "yes ''" through the make oldconfig may enable
things we do not want enabled. If something is default enabled, the
yes command with '' as an argument will enable it.
Use oldnoconfig, which runs everything as if 'no' was used.

Change the config to use TEST_START where the options after a
TEST_START automatically get the [] as it is read and they do
not need to exist in the config file;
TEST_START
MIN_CONFIG = myconfig
is the same as
MIN_CONFIG[1] = myconfig
The benefit is that you no longer need to keep track of test numbers
with tests.
Also process the commit ids that are passed to the options
to get the actually SHA1 so it is no longer relative to the branch.
Ie, saying HEAD will get the current SHA1 and then that will
be used, and will work even if another branch is checked out.

Add a POST_INSTALL option that runs after the build and install
but before rebooting to the test kernel. This alls the user to
run a script that will install an initrd (or anything else that may
be special) before booting.

It is much better to keep the monitor running throughout a
test than to constantly start and stop it. Some console readers
will show everything that has happened before when opening the
console, and by opening it several times, causes the old content to
be read multiple times in a single test.

Add basic module probe support on perf probe. This introduces "--module
<MODNAME>" option to perf probe for putting probes and showing lines and
variables in the given module.
Currently, this supports only probing on running modules. Supporting off-line
module probing is the next step.
e.g.)
[show lines]
# ./perf probe --module drm -L drm_vblank_info
<drm_vblank_info:0>
0 int drm_vblank_info(struct seq_file *m, void *data)
1 {
struct drm_info_node *node = (struct drm_info_node *) m->private
3 struct drm_device *dev = node->minor->dev;
...
[show vars]
# ./perf probe --module drm -V drm_vblank_info:3
Available variables at drm_vblank_info:3
@<drm_vblank_info+20>
(unknown_type) data
struct drm_info_node* node
struct seq_file* m
[put a probe]
# ./perf probe --module drm drm_vblank_info:3 node m
Add new event:
probe:drm_vblank_info (on drm_vblank_info:3 with node m)
You can now use it on all perf tools, such as:
perf record -e probe:drm_vblank_info -aR sleep 1

# ./perf probe -l

Both python_scripting_ops and perl_scripting_ops have two global definitions.
One in trace-event-scripting.c and one in their respective scripting-engine
modules.
The issue is that depending on the linker order one definition or the other
is chosen. One is uninitialized (bss), while the other is initialized. If
the uninitialized version is chosen, then perf does not function properly.
This patch fixes this by adding the extern prefix to the definitions in
trace-event-scripting.c.
