When probing the bus, we need to set the byte count

git://people.freedesktop.org/~danvet/drm-intel into drm-fixes
Just flushing out my pile of bugfixes, most of them for regressions/cc:
stable. Nothing really serious going on.
For outstanding issues we still have the S4 fun due to the hsw S4
duct-tape pending (seems like I need to switch into angry maintainer mode
on that one). And there's the mode merging revert to make my g33 work
again still pending for drm core. For that one I don't have any more clue
(and it looks like no one else has a good idea either). And apparently the
locking WARN fix in here also needs to be replicated for boot, still
confirming that one though.

Comments:
In the latest version (4.7.3) of gcc compiler, it requres that
libraries must follow the object or source files like below:
"gcc hello.c -lpthread" instead of "gcc -lpthread hello.c"
And it isn't encountered at gcc version 4.7.2.
So this patch fix to move the pthread option after testusb.c.

In checkin:
0c44c2d0f459 x86: Use asm goto to implement better modify_and_test() functions
the various functions which do modify and test were unified and
optimized using "asm goto". However, this change missed the detail
that the bitops require an "Ir" constraint rather than an "er"
constraint ("I" = integer constant from 0-31, "e" = signed 32-bit
integer constant). This would cause code to miscompile if these
functions were used on constant bit positions 32-255 and the build to
fail if used on constant bit positions above 255.
Add the constraints as a parameter to the GEN_BINARY_RMWcc() macro to
avoid this problem.

Also request kernel ttm_buffer objects for buffer objects that obviously
aren't visible to user-space, and save some device address space.
The accounting was broken in a couple of ways:
1) We did not differentiate between user dma buffers and kernel dma buffers.
2) The ttm_bo_acc_size function is broken in that it
a) Doesn't take into account the size of the optional dma address array,
b) Doesn't take into account the fact that drivers typically embed the
ttm_tt structure.
This needs to be fixed in ttm, but meanwhile provide a vmwgfx-specific
function to do the job.

Removing options support as it's not backported yet.
Currently this plugin supports 2 options:
'parent' to display parent function
'indent' to show function call indents
Enabling both of them by default.

- some of the tracepoints keep the same output even with
the plugin handling: kvm:kvm_exit, kvm:kvm_emulate_insn
- the 'kvmmmu:fast_page_fault' is still broken because of
missing is_writable_pte function and is fixed in another patch
- ommited following tracepoints from backport because
the output was buggy

In order to get the proper plugins processing we need to use full
trace-event interface when creating tracepoint events. So far we were
using shortcut to get the parsed format.
Moving current 'event_format__new' function into trace-event object as
'trace_event__tp_format'.
This function uses properly initialized global trace-event object,
ensuring proper plugins processing.

Add trace-event object to keep together 'struct pevent' object with its
loaded plugins with following interface:
int trace_event__init(struct trace_event *t);
- Initalizes 'struct pevent' object and loads plugins for it
void trace_event__cleanup(struct trace_event *t);
- Cleanups both 'struct pevent' and plugins

Adding filename__read_str util function to read
text file and return it in the char array.
The interface is:
int filename__read_str(const char *filename, char **buf, size_t *sizep)
Returns 0/-1 if the read suceeded/fail respectively.
buf - place to store the data pointer
size - place to store data size
v2 change:
- better error handling suggested by Namhyung Kim.

not fit to the rest of the build messages we use.

Changing the pevent_parse_format interface to include the pevent handle.
The goal is to always use pevent object when dealing with traceevent
library. The reason is that we might need additional processing (like
plugins), which is not possible otherwise.
Patches follow to make this happen completely.

Backporting missing pieces of plugin building infrastructure:
- Adding Makefile 'plugins' target to build all
defined plugins
- Adding Makefile 'install_plugins' target as 'install_lib'
target dependency
- Link plugin objects with shared object building
Backported from Steven Rostedt's trace-cmd repo (HEAD 0f2c2fb):
git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/trace-cmd.git
Plugins are by default installed into following locations:
'$(HOME)/.traceevent/plugins'
- If we are installing under $(HOME)
'$(prefix)/lib/traceevent/plugins'
- Otherwise
This path is propagated to the plugin object as a plugins search path.

Backporting plugin support for traceevent lib.
Backported from Steven Rostedt's trace-cmd repo (HEAD 0f2c2fb):
git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/trace-cmd.git
It's now possible to use following interface to load plugins
(shared objects) to enhance pevent object functionality.
The plugin interface/hooks are as follows:
(taken from event-parse.h comments)
- 'pevent_plugin_loader' (required)
The function name to initialized the plugin.
int pevent_plugin_loader(struct pevent *pevent)
- 'pevent_plugin_unloader' (optional)
The function called just before unloading
int pevent_plugin_unloader(void)
- 'pevent_plugin_options' (optional)
Plugin options that can be set before loading
struct plugin_option pevent_plugin_options[] = {
{
.name = "option-name",
.plugin_alias = "overide-file-name", (optional)
.description = "description of option to show users",
},
{
.name = NULL,
},
};
Array must end with .name = NULL;
The plugin_alias (below) can be used to give a shorter
name to access the variable. Useful if a plugin handles
more than one event.
NOTE options support is not backported yet.
- 'pevent_plugin_alias' (optional)
The name to use for finding options (uses filename if not defined)
New traceevent functions are added to search and load
available plugins:
struct plugin_list*
traceevent_load_plugins(struct pevent *pevent)
- loads plusing for 'struct pevent' object and returns
loaded plugins list
void traceevent_unload_plugins(struct plugin_list *plugin_list);
- unload plugin list

As we have changed the default behavior of 'perf kvm' to --guest

As option --host and --guest request no input for it, there should not
be a '=' after them in the man page sources.
And --output expects a filename as the input, so there should be a '='
after it.
This patch removes the needless '=' after --guest and --host, and adds a
'=' after --output in perf-kvm.txt.
