* ACPI, APEI, Add APEI bit support in generic _OSC callHuang Ying2011-07-13
| | | | | | | | | | | | | | | | | | | | | In APEI firmware first mode, hardware error is reported by hardware to firmware firstly, then firmware reports the error to Linux in a GHES error record via POLL/SCI/IRQ/NMI etc. This may result in some issues if OS has no full APEI support. So some firmware implementation will work in a back-compatible mode by default. Where firmware will only notify OS in old-fashion, without GHES record. For example, for a fatal hardware error, only NMI is signaled, no GHES record. To gain full APEI power on these machines, APEI bit in generic _OSC call can be specified to tell firmware that Linux has full APEI support. This patch adds the APEI bit support in generic _OSC call.

* ACPI, APEI, GHES, Prevent GHES to be built as moduleHuang Ying2011-07-13
| | | | | | | | | | | | | | GHES (Generic Hardware Error Source) is used to process hardware error notification in firmware first mode. But because firmware first mode can be turned on but can not be turned off, it is unreasonable to unload the GHES module with firmware first mode turned on. To avoid confusion, this patch makes GHES can be enabled/disabled in configuration time, but not built as module and unloaded at run time.

* ACPI, APEI, Add apei_exec_run_optionalHuang Ying2011-07-13
| | | | | | | | | | | | | | | | | | Some actions in APEI ERST and EINJ tables are optional, for example, ACPI_EINJ_BEGIN_OPERATION action is used to do some preparation for error injection, and firmware may choose to do nothing here. While some other actions are mandatory, for example, firmware must provide ACPI_EINJ_GET_ERROR_TYPE implementation. Original implementation treats all actions as optional (that is, can have no instructions), that may cause issue if firmware does not provide some mandatory actions. To fix this, this patch adds apei_exec_run_optional, which should be used for optional actions. The original apei_exec_run should be used for mandatory actions.

* ACPI, APEI, GHES, Do not ratelimit fatal error printk before panicHuang Ying2011-07-13
| | | | | | | | | | | | | | | printk is used by GHES to report hardware errors. Normally, the printk will be ratelimited to avoid too many hardware error reports in kernel log. Because there may be thousands or even millions of corrected hardware errors during system running. That is different for fatal hardware error, because system will go panic as soon as possible, there will be no more than several error records. And these error records are valuable for system fault diagnosis, so they should not be ratelimited. Signed-off-by: Huang Ying <ying.huang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Just compiling pseries in the kernel causes it to override memory_block_size_bytes() regardless of what is the runtime platform. This cleans up the implementation of that function, fixing a bug or two while at it, so that it's harmless (and potentially useful) for other platforms. Without this, bugs in that code would trigger a WARN_ON() in drivers/base/memory.c when booting some different platforms. If/when we have another platform supporting memory hotplug we might want to either move that out to a generic place or make it a ppc_md. callback.

| * | | genirq: replace irq_gc_ack() with {set,clr}_bit variants (fwd)Simon Guinot2011-07-07

Depending on the device, interrupts acknowledgement is done by setting or by clearing a dedicated register. Replace irq_gc_ack() with some {set,clr}_bit variants allows to handle both cases. Note that this patch affects the following SoCs: Davinci, Samsung and Orion. Except for this last, the change is minor: irq_gc_ack() is just renamed into irq_gc_ack_set_bit(). For the Orion SoCs, the edge GPIO interrupts support is currently broken. irq_gc_ack() try to acknowledge a such interrupt by setting the corresponding cause register bit. The Orion GPIO device expect the opposite. To fix this issue, the irq_gc_ack_clr_bit() variant is used. Tested on Network Space v2.

Still, it's best to clean up completely in the failure path, which is easily done by calling mtrr_del if the mtrr was successfully allocated. i915_driver_load calls i915_gem_load which register i915_gem_inactive_shrink. If i915_driver_load fails after calling i915_gem_load, the shrinker will be left registered. When called, it will access freed memory and crash. The fix is to unregister the shrinker in the failure path using code duplicated from i915_driver_unload. i915_driver_load also has some incorrect gotos in the error cleanup paths: * After failing to initialize the GTT (which cannot happen, btw, intel_gtt_get returns a fixed (non-NULL) value), it tries to free the uninitialized WC IO mapping.

| * | [media] tuner-core.c: don't change type field in g_tuner or g_frequencyHans Verkuil2011-07-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The tuner core should not silently change the type field in g_tuner and g_frequency. If the tuner is in a different mode than the one that was requested, then just fill in what you can and don't attempt to read afc, signal or rxsubchans values.

| | | | | | | | | | | | | | | | | | | | | | | | The driver shouldn't override vt->type, and the tuner name should be based on vt->type as well. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
| * | [media] tuner-core: power up tuner when called with s_power(1)Hans Verkuil2011-07-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Drivers must be able to rely on s_power to power up subdevices. Note that at this moment no driver attempts to power up tuners. This probably isn't surprising since s_power(1) was never implemented in tuner-core.c until now.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Prohibit attempts to change the tuner to a type that is different from the device node the ioctl is called from. I.e. the type must be RADIO for a radio node and ANALOG_TV for a video/vbi node. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| * | [media] feature-removal-schedule: change in how radio device nodes are handledHans Verkuil2011-07-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Radio devices have weird side-effects when used with combined TV/radio tuners and the V4L2 spec is ambiguous on how it should work. This results in inconsistent driver behavior which makes life hard for everyone. Be more strict in when and how the switch between radio and tv mode takes place and make sure all drivers behave the same.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The tuner-core subdev requires that the type field of v4l2_tuner is filled in correctly. This is done in v4l2-ioctl.c, but pvrusb2 doesn't use that yet, so we have to do it manually based on whether the current input is radio or not. Tested with my pvrusb2.
