2013-09-03[SCSI] mpt3sas: Added a driver module parameter max_msix_vectorsSreekanth Reddy1-0/+14
Added a driver module parameter max_msix_vectors. Using this module parameter the maximum number of MSI-X vectors could be set. The number of MSI-X vectors used would be the minimum of MSI-X vectors supported by the HBA, the number of CPU cores and the value set to max_msix_vectors module parameter. The default value of this module parameter is set to 8. The default value of this parameter is set to 8 inorder to reduce the amount of memory required for Reply Descriptor Post queue. This is because with the higher MSI-X vectors, some times kernel is not able to allocate the requested amount of memory and crash is observed. To overcome this problem, the default value is set to 8.

2013-09-03[SCSI] mpt2sas: Fix for kernel panic when driver loads with HBA connected to ↵Sreekanth Reddy1-0/+14
non LUN 0 configured expander With some enclosures when LUN 0 is not created but LUN 1 or LUN X is created then SCSI scan procedure calls target_alloc, slave_alloc call back functions for LUN 0 and slave_destory() for same LUN 0. In these kind of cases within slave_destroy, pointer to scsi_target in _sas_device structure is set to NULL, following which when slave_alloc for LUN 1 is called then starget would not be set properly for this LUN. So, scsi_target pointer pointing to NULL value would lead to a crash later in the discovery procedure. To solve this issue set the sas_device's scsi_target pointer to scsi_device's scsi_target if it is NULL earlier in slave_alloc callback function.

2013-09-03[SCSI] mpt2sas: when Async scanning is enabled then while scanning, devices ↵Sreekanth Reddy1-10/+13
are removed but their transport layer entries are not removed When Async scanning mode is enabled and device scanning is in progress then devices should not be removed. But in actuality, devices are removed but their transport layer entries are not removed. This causes error to add the same device to the transport layer after host reset or diagnostic reset. So, in this patch, modified the code in such a way that device is not removed when Async scanning mode is enabled and device scanning is in progress.

Removed the check for the presence of volumes before sending down MPI2_RAID_ACTION_SYSTEM_SHUTDOWN_INITIATED. Therefore, this RAID action would be sent if the card is IR Firmware. 2.

2013-09-03pwm: pxa: Use module_platform_driverMike Dunn1-11/+1
Commit 76abbdde2d95a3807d0dc6bf9f84d03d0dbd4f3d pwm: Add sysfs interface causes a kernel oops due to a null pointer dereference on PXA platforms. This happens because the class added by the patch is registered in a subsys_initcall (initcall4), but the pxa pwm driver is registered in arch_initcall (initcall3). If the class is not registered before the driver probe function runs, the oops occurs in device_add() when the uninitialized pointers in struct class are dereferenced. I don't see a reason that the driver must be an arch_initcall, so this patch makes it a regular module_platform_driver (initcall6), preventing the oops.
