2011-08-03ACPI, APEI, GHES, Error records content based throttleHuang Ying1-7/+177
printk is used by GHES to report hardware errors. Ratelimit is enforced on the printk 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. Currently, a simple scheme is used. That is, the total number of hardware error reporting is ratelimited. This may cause some issues in practice. For example, there are two kinds of hardware errors occurred in system. One is corrected memory error, because the fault memory address is accessed frequently, there may be hundreds error report per-second. The other is corrected PCIe AER error, it will be reported once per-second. Because they share one ratelimit control structure, it is highly possible that only memory error is reported. To avoid the above issue, an error record content based throttle algorithm is implemented in the patch. Where after the first successful reporting, all error records that are same are throttled for some time, to let other kinds of error records have the opportunity to be reported. In above example, the memory errors will be throttled for some time, after being printked. Then the PCIe AER error will be printked successfully.

2011-08-03ACPI, APEI, GHES, printk support for recoverable error via NMIHuang Ying2-18/+193
Some APEI GHES recoverable errors are reported via NMI, but printk is not safe in NMI context. To solve the issue, a lock-less memory allocator is used to allocate memory in NMI handler, save the error record into the allocated memory, put the error record into a lock-less list. On the other hand, an irq_work is used to delay the operation from NMI context to IRQ context. The irq_work IRQ handler will remove nodes from lock-less list, printk the error record and do some further processing include recovery operation, then free the memory.

2011-07-14ACPI, APEI, Add WHEA _OSC supportHuang Ying3-0/+38
APEI firmware first mode must be turned on explicitly on some machines, otherwise there may be no GHES hardware error record for hardware error notification. APEI bit in generic _OSC call can be used to do that, but on some machine, a special WHEA _OSC call must be used. This patch adds the support to that WHEA _OSC call.

2011-07-14ACPI, APEI, Add APEI bit support in generic _OSC callHuang Ying1-2/+14
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.

2011-07-14ACPI, APEI, GHES, Prevent GHES to be built as moduleHuang Ying1-1/+1
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.

2011-07-14ACPI, APEI, Add apei_exec_run_optionalHuang Ying2-5/+17
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.

2011-07-14ACPI, APEI, GHES, Do not ratelimit fatal error printk before panicHuang Ying1-11/+14
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>

2011-07-12drm/i915: Clean up i915_driver_load failure pathKeith Packard1-3/+11
i915_driver_load adds a write-combining MTRR region for the GTT aperture to improve memory speeds through the aperture. If i915_driver_load fails after this, it would not have cleaned up the MTRR. This shouldn't cause any problems, except for consuming an MTRR register. 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.

2011-07-09drivers/leds/leds-pca9532.c: change driver name to be uniqueWolfram Sang1-1/+1
This driver handles the variants pca9530-pca9533, so it chose the name "pca953x". However, there is a gpio driver which decided on the same name. As a result, those two can't be loaded at the same time. Add a subsystem prefix to make the driver name unique. Device matching will not suffer, because both are I2C drivers which match using a i2c_device_id-table which is not altered.

2011-07-09w1: ds1wm: add a reset recovery parameterJean-François Dagenais3-0/+7
This fixes a regression in 3.0 reported by Paul Parsons regarding the removal of the msleep(1) in the ds1wm_reset() function: : The linux-3.0-rc4 DS1WM 1-wire driver is logging "bus error, retrying" : error messages on an HP iPAQ hx4700 PDA (XScale-PXA270): : : <snip> : Driver for 1-wire Dallas network protocol. : DS1WM w1 busmaster driver - (c) 2004 Szabolcs Gyurko : 1-Wire driver for the DS2760 battery monitor chip - (c) 2004-2005, Szabolcs Gyurko : ds1wm ds1wm: pass: 1 bus error, retrying : ds1wm ds1wm: pass: 2 bus error, retrying : ds1wm ds1wm: pass: 3 bus error, retrying : ds1wm ds1wm: pass: 4 bus error, retrying : ds1wm ds1wm: pass: 5 bus error, retrying : ... : : The visible result is that the battery charging LED is erratic; sometimes : it works, mostly it doesn't. : : The linux-2.6.39 DS1WM 1-wire driver worked OK. I haven't tried 3.0-rc1, : 3.0-rc2, or 3.0-rc3. This sleep should not be required on normal circuitry provided the pull-ups on the bus are correctly adapted to the slaves. Unfortunately, this is not always the case. The sleep is restored but as a parameter to the probe function in the pdata.

2011-07-09hwmon: (lm95241) Fix chip detection codeGuenter Roeck1-1/+1
The LM95241 driver accepts every chip ID equal to or larger than 0xA4 as its own, and other chips such as LM95245 use chip IDs in the accepted ID range. This results in false chip detection. Fix problem by accepting only the known LM95241 chip ID. Signed-off-by: Guenter Roeck <guenter.roeck@ericsson.com> Acked-by: Jean Delvare <khali@linux-fr.org> Cc: stable@kernel.org # 2.6.30+
2011-07-09PCI: conditional resource-reallocation through kernel parameter pci=reallocRam Pai3-0/+19
Multiple attempts to dynamically reallocate pci resources have unfortunately lead to regressions. Though we continue to fix the regressions and fine tune the dynamic-reallocation behavior, we have not reached a acceptable state yet. This patch provides a interim solution. It disables dynamic reallocation by default, but adds the ability to enable it through pci=realloc kernel command line parameter.

The platform_data (pdata) may be pointing to __initdata section, which may be free'd from the memory. The dependency on pdata in non-init functions is removed in this patch to allow platform to declare __initdata for platform data.
