2013-01-26spi/pxa2xx: convert to the common clk frameworkMika Westerberg
Convert clk_enable() to clk_prepare_enable() and clk_disable() to clk_disable_unprepare() respectively in order to support the common clk framework. Otherwise we get warnings on the console as the clock is not prepared before it is enabled. In addition we must cache the maximum clock rate to drv_data->max_clk_rate at probe time because clk_get_rate() cannot be called in tasklet context.

2013-01-26PM / tracing: remove deprecated power trace APIPaul Gortmaker
The text in Documentation said it would be removed in 2.6.41; the text in the Kconfig said removal in the 3.1 release. Either way you look at it, we are well past both, so push it off a cliff. Note that the POWER_CSTATE and the POWER_PSTATE are part of the legacy tracing API. Remove all tracepoints which use these flags. As can be seen from context, most already have a trace entry via trace_cpu_idle anyways. Also, the cpufreq/cpufreq.c PSTATE one is actually unpaired, as compared to the CSTATE ones which all have a clear start/stop. As part of this, the trace_power_frequency also becomes orphaned, so it too is deleted.

Observe that acpi_get_child() doesn't need to use the helper struct acpi_find_child structure and change it to work without it. Also, using acpi_get_object_info() to get the output of _ADR for the given device is overkill, because that function does much more than just evaluating _ADR (let alone the additional memory allocation done by it). Moreover, acpi_get_child() doesn't need to loop any more once it has found a matching handle, so make it stop in that case. To prevent the results from changing, make it use do_acpi_find_child() as a post-order callback. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

2013-01-25USB: EHCI: fix timer bug affecting port resumeAlan Stern
This patch (as1652) fixes a long-standing bug in ehci-hcd. The driver relies on status polls to know when to stop port-resume signalling. It uses the root-hub status timer to schedule these status polls. But when the driver for the root hub is resumed, the timer is rescheduled to go off immediately -- before the port is ready. When this happens the timer does not get re-enabled, which prevents the port resume from finishing until some other event occurs. The symptom is that when a new device is plugged in, it doesn't get recognized or enumerated until lsusb is run or something else happens. The solution is to re-enable the root-hub status timer after every status poll while a port resume is in progress. This bug hasn't surfaced before now because we never used to try to suspend the root hub in the middle of a port resume (except by coincidence).

2013-01-25USB: add usb_hcd_{start,end}_port_resumeAlan Stern
This patch (as1649) adds a mechanism for host controller drivers to inform usbcore when they have begun or ended resume signalling on a particular root-hub port. The core will then make sure that the root hub does not get runtime-suspended while the port resume is going on. Since commit 596d789a211d134dc5f94d1e5957248c204ef850 (USB: set hub's default autosuspend delay as 0), the system tries to suspend hubs whenever they aren't in use. While a root-hub port is being resumed, the root hub does not appear to be in use. Attempted runtime suspends fail because of the ongoing port resume, but the PM core just keeps on trying over and over again. We want to prevent this wasteful effort.

2013-01-25USB: EHCI: unlink one async QH at a timeAlan Stern
This patch (as1648) fixes a regression affecting nVidia EHCI controllers. Evidently they don't like to have more than one async QH unlinked at a time. I can't imagine how they manage to mess it up, but at least one of them does. The patch changes the async unlink logic in two ways: Each time an IAA cycle is started, only the first QH on the async unlink list is handled (rather than all of them). Async QHs do not all get unlinked as soon as they have been empty for long enough. Instead, only the last one (i.e., the one that has been on the schedule the longest) is unlinked, and then only if no other unlinks are in progress at the time. This means that when multiple QHs are empty, they won't be unlinked as quickly as before. That's okay; it won't affect correct operation of the driver or add an excessive load. Multiple unlinks tend to be relatively rare in any case.

2013-01-25USB: EHCI: remove ASS/PSS polling timeoutAlan Stern
This patch (as1647) attempts to work around a problem that seems to affect some nVidia EHCI controllers. They sometimes take a very long time to turn off their async or periodic schedules. I don't know if this is a result of other problems, but in any case it seems wise not to depend on schedule enables or disables taking effect in any specific length of time. The patch removes the existing 20-ms timeout for enabling and disabling the schedules. The driver will now continue to poll the schedule state at 1-ms intervals until the controller finally decides to obey the most recent command issued by the driver. Just in case this hides a problem, a debugging message will be logged if the controller takes longer than 20 polls. I don't know if this will actually fix anything, but it can't hurt.

2013-01-25ACPI / PM: Fix consistency check for power resources during resumeRafael J. Wysocki
During system resume we check if there are power resources that have been turned off by the BIOS, but our reference counters for them are nonzero (they need to be turned on then). It turns out, however, that we also need to check the opposite, i.e. if there are power resources that have been turned on by the BIOS, but our reference counters for them are zero (which means that no devices are going to need them any time soon) and we should turn them off. Make the power resources resume code do the additional check and turn off the unused power resources as appropriate. This change has been tested on HP nx6325. Signed-off-by: Rafael J.

Since ACPI power resources are going to be used more extensively on new hardware platforms, it is necessary to allow user space (powertop in particular) to look at the lists of power resources corresponding to different power states of devices for diagnostics and control purposes. For this reason, for each power state of an ACPI device node using power resources create a special attribute group under the device node's directory in sysfs containing links to sysfs directories representing the power resources in that list. The names of the new attribute groups are "power_resources_<state>", where <state> is the state name i.e. "D0", "D1", "D2", or "D3hot". Signed-off-by: Rafael J.

2013-01-25ALSA: Make snd_printd() and snd_printdd() inlineTakashi Iwai
Because currently snd_printd() and snd_printdd() macros are expanded to empty when CONFIG_SND_DEBUG=n, a compile warning like below appears sometimes, and we had to covert it by ugly ifdefs: sound/pci/hda/patch_sigmatel.c: In function ‘stac92hd71bxx_fixup_hp’: sound/pci/hda/patch_sigmatel.c:2434:24: warning: unused variable ‘spec’ [-Wunused-variable] For "fixing" these issues better, this patch replaces snd_printd() and snd_printdd() definitions with empty inline functions instead of macros. This should have the same effect but shut up warnings like above. But since we had already put ifdefs, changing to inline functions would trigger compile errors. So, such ifdefs is removed in this patch. In addition, snd_pci_quirk name field is defined only when CONFIG_SND_DEBUG_VERBOSE is set, and the reference to it in snd_printdd() argument triggers the build errors, too. For avoiding these errors, introduce a new macro snd_pci_quirk_name() that is defined no matter how the debug option is set.

2013-01-25async: initialise list heads to fix crashJames Hogan
9fdb04cdc55 ("async: replace list of active domains with global list of pending items") added a struct list_head global_list in struct async_entry, which isn't initialised. This means that if !domain->registered at __async_schedule(), then list_del_init() will be called on the list head in async_run_entry_fn with both pointers NULL, causing a crash. This is fixed by initialising both the global_list and domain_list list_heads after kzalloc'ing the entry. This was noticed due to dapm_power_widgets() which uses ASYNC_DOMAIN_EXCLUSIVE, which initialises the domain->registered to 0.

2013-01-25tracing: Remove tracepoint sample codeSteven Rostedt
The tracepoint sample code was used to teach developers how to create their own tracepoints. But now the trace_events have been added as a higher level that is used directly by developers today. Only the trace_event code should use the tracepoint interface directly and no new tracepoints should be added. Besides, the example had a race condition with the use of the ->d_name.name dentry field, as pointed out by Al Viro. Best just to remove the code so it wont be used by other developers.
