2010-08-03[CPUFREQ] x86 cpufreq: Make trace_power_frequency cpufreq driver independentThomas Renninger
and fix the broken case if a core's frequency depends on others. trace_power_frequency was only implemented in a rather ungeneric way in acpi-cpufreq driver's target() function only. -> Move the call to trace_power_frequency to cpufreq.c:cpufreq_notify_transition() where CPUFREQ_POSTCHANGE notifier is triggered. This will support power frequency tracing by all cpufreq drivers trace_power_frequency did not trace frequency changes correctly when the userspace governor was used or when CPU cores' frequency depend on each other. -> Moving this into the CPUFREQ_POSTCHANGE notifier and pass the cpu which gets switched automatically fixes this. Robert Schoene provided some important fixes on top of my initial quick shot version which are integrated in this patch: - Forgot some changes in power_end trace (TP_printk/variable names) - Variable dummy in power_end must now be cpu_id - Use static 64 bit variable instead of unsigned int for cpu_id Signed-off-by: Thomas Renninger <trenn@suse.de> CC: davej@redhat.com CC: arjan@infradead.org CC: linux-kernel@vger.kernel.org CC: robert.schoene@tu-dresden.de Tested-by: robert.schoene@tu-dresden.de Signed-off-by: Dave Jones <davej@redhat.com>

The io ports used are added to /proc/ioports in another patch. Beside the fact that /proc/acpi is deprecated for quite some time, this info is not needed for applications and thus can be moved to debugfs instead of a public interface like /sys.

Other patches in this series add the same info to /sys/... and /proc/ioports. The info removed should never have been used in an application, eventually someone read it manually. /proc/acpi is deprecated for more than a year anyway...

2010-08-03panasonic-laptop: fix acpi_pcc_write_sset return valueAxel Lin
In current implementation, acpi_pcc_write_sset return 1 if write is successful, 0 if write is failed. But all the callers consider acpi_pcc_write_sset return 0 if write is successful and return negtive if write is failed. This patch changes the implementation of acpi_pcc_write_sset to return 0 if write is successful, -EIO if write is failed.

2010-08-03eeepc-laptop: fix hotplug_disabled module_param permissionsAxel Lin
The hotplug_disabled module parameter is determinated at the module load time. Change the value after the module is loaded does not make sense and has no effect at all, thus set the permissions to 0444 instead of 0644.

2010-08-03asus-laptop: fix wapf, wlan_status and bluetooth_status module_param permissionsAxel Lin
The wapf module parameters defines the behavior of the Fn+Fx wlan key. The wlan_status and bluetooth_status module parameters are for setting the wlan/bluetooth status on boot. All above module parameters are determinated only at the module load time. Change the value after the module is loaded does not make sense and has no effect at all, thus set the permissions to 0444 instead of 0644.

2010-08-03acer-wmi: fix memory leaks in wmab_execute error pathAxel Lin
When acpi_evaluate_object() is passed ACPI_ALLOCATE_BUFFER, the caller must kfree the returned buffer if AE_OK is returned. Call Trace: wmab_execute -> wmi_evaluate_method -> acpi_evaluate_object Thus if callers of wmab_execute() pass ACPI_ALLOCATE_BUFFER, the return buffer must be kfreed if wmab_execute return AE_OK.

2010-08-03acer-wmi: fix memory leaks in WMID_set_capabilities and get_wmid_devicesAxel Lin
When acpi_evaluate_object() is passed ACPI_ALLOCATE_BUFFER, the caller must kfree the returned buffer if AE_OK is returned. The callers of wmi_query_block() pass ACPI_ALLOCATE_BUFFER, and thus must check its return value before accessing or kfree() on the buffer. This patch adds a missing kfree(out.pointer) before exit WMID_set_capabilities() and get_wmid_devices().
