2008-12-18ftrace: add not to regex on filtering functionsSteven Rostedt
Impact: enhancement Ingo Molnar has asked about a way to remove items from the filter lists. Currently, you can only add or replace items. The way items are added to the list is through opening one of the list files (set_ftrace_filter or set_ftrace_notrace) via append. If the file is opened for truncate, the list is cleared. echo spin_lock > /debug/tracing/set_ftrace_filter The above will replace the list with only spin_lock echo spin_lock >> /debug/tracing/set_ftrace_filter The above will add spin_lock to the list. Now this patch adds: echo '!spin_lock' >> /debug/tracing/set_ftrace_filter This will remove spin_lock from the list. The limited glob features of these lists also can be notted. echo '!spin_*' >> /debug/tracing/set_ftrace_filter This will remove all functions that start with 'spin_' Note: echo '!spin_*' > /debug/tracing/set_ftrace_filter will simply clear out the list (notice the '>' instead of '>>') Signed-off-by: Steven Rostedt <srostedt@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-12-18trace: better use of stack_trace_enabled for boot up codeSteven Rostedt
Impact: clean up Andrew Morton suggested to use the stack_tracer_enabled variable to decide whether or not to start stack tracing on bootup. This lets us remove the start_stack_trace variable.

2008-12-18trace: add a way to enable or disable the stack tracerSteven Rostedt
Impact: enhancement to stack tracer The stack tracer currently is either on when configured in or off when it is not. It can not be disabled when it is configured on. (besides disabling the function tracer that it uses) This patch adds a way to enable or disable the stack tracer at run time. It defaults off on bootup, but a kernel parameter 'stacktrace' has been added to enable it on bootup. A new sysctl has been added "kernel.stack_tracer_enabled" to let the user enable or disable the stack tracer at run time.

2008-12-18ALSA: hda - Fix silent HP output on D975Takashi Iwai
Some desktops seems to have no HP/mic jack detection on the front panel, which results in the silent output in the recent driver, because the driver mutes the output (to save power) when no plug is detected. This patch adds a new model that disables the jack-detection. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2008-12-17PCI hotplug: ibmphp: Fix module ref count underflowNeil Horman
I happened to notice that the ibmphp hotplug driver does something rather silly in its init routine. It purposely calls module_put so as to underflow its module ref count to avoid being removed from the kernel. This is bad practice, and wrong, since it provides a window for subsequent module_gets to reset the refcount to zero, allowing an unload to race in and cause all sorts of mysterious panics. If the module is unsafe to load, simply omitting the module_exit parameter is sufficient to prevent the kernel from allowing the unload.
