Merge branch 'akpm' (Andrew's patch-bomb)

2012-06-01T01:10:18+00:00

Merge misc patches from Andrew Morton: - the "misc" tree - stuff from all over the map - checkpatch updates - fatfs - kmod changes - procfs - cpumask - UML - kexec - mqueue - rapidio - pidns - some checkpoint-restore feature work. Reluctantly. Most of it delayed a release. I'm still rather worried that we don't have a clear roadmap to completion for this work. * emailed from Andrew Morton : (78 patches) kconfig: update compression algorithm info c/r: prctl: add ability to set new mm_struct::exe_file c/r: prctl: extend PR_SET_MM to set up more mm_struct entries c/r: procfs: add arg_start/end, env_start/end and exit_code members to /proc/$pid/stat syscalls, x86: add __NR_kcmp syscall fs, proc: introduce /proc//task//children entry sysctl: make kernel.ns_last_pid control dependent on CHECKPOINT_RESTORE aio/vfs: cleanup of rw_copy_check_uvector() and compat_rw_copy_check_uvector() eventfd: change int to __u64 in eventfd_signal() fs/nls: add Apple NLS pidns: make killed children autoreap pidns: use task_active_pid_ns in do_notify_parent rapidio/tsi721: add DMA engine support rapidio: add DMA engine support for RIO data transfers ipc/mqueue: add rbtree node caching support tools/selftests: add mq_perf_tests ipc/mqueue: strengthen checks on mqueue creation ipc/mqueue: correct mq_attr_ok test ipc/mqueue: improve performance of send/recv selftests: add mq_open_tests ...

drivers/message/fusion: use pci_dev->revision

2012-06-01T00:49:26+00:00

This driver uses PCI_CLASS_REVISION instead of PCI_REVISION_ID, so it wasn't converted by 44c10138fd4bbc ("PCI: Change all drivers to use pci_device->revision"). In one case, it even reads PCI revision ID without using it -- that code is now removed...

[SCSI] mptfusion: unlock on error in mpt_config()

PCI: Rename pci_remove_bus_device to pci_stop_and_remove_bus_device

2012-02-27T20:12:18+00:00

The old pci_remove_bus_device actually did stop and remove. Make the name reflect that to reduce confusion. This patch is done by sed scripts and changes back some incorrect __pci_remove_bus_device changes. Suggested-by: Jesse Barnes Signed-off-by: Yinghai Lu Signed-off-by: Jesse Barnes

[SCSI] fusion: ensure NUL-termination of MptCallbacksName elements

2011-12-15T06:57:29+00:00

Using strlcpy instead of memcpy makes the strlen() calls superfluous and also ensures zero-termination of the copied string. At the same time get rid of the magic constant 50. Actually, I can't see why copying the callback name is necessary instead of simply storing a pointer to it (just like to the callback function itself), but that goes beyond the scope of this fix.

[SCSI] mptfusion: Fix for device offline while doing aggressive HBA reset

2011-08-27T14:35:53+00:00

[Resend patch as per Bernd Schubert comment ] Issue: Device goes offline while doing aggressive HBA reset along with IO using some utility. Root cause: FW goes into bad state due to aggressive reset. Softreset does not help to recover FW. And also aggressive reset open up the window for Error handling thread to kicked off at the same time HBA will be in constant RESET loop as part of aggressive reset test case can lead Device to goes offline. Changes: 1. Added extra check as below inside eh_timed_out call back as below. if(ioc->ioc_reset_in_progress) Rc = EH_TIMER_RESET 2. Removed " DOORBELL_ACTIVE" check for SAS controller from task management context. Since SAS controller uses high priority queue for task management. This check is not required for SAS controller. 3. Moved SoftReset call to HardReset from Task Mgmt context. Signed-off-by: Kashyap Desai Signed-off-by: James Bottomley

[SCSI] mptfusion: Better handling of DEAD IOC PCI-E Link down error condition

2011-08-27T14:35:16+00:00

Find Non-Operation IOC and remove it from OS: Detecting dead(non-functional) ioc will be done reading doorbell register value from fault reset thread, which has been called from work thread context after each specific interval. If doorbell value is 0xFFFFFFFF, it will be considered as IOC is non-operational and marked as dead ioc. Once Dead IOC has been detected, it will be removed at pci layer using "pci_remove_bus_device" API. Signed-off-by: Kashyap Desai Signed-off-by: James Bottomley

treewide: cleanup continuations and remove logging message whitespace

2011-04-26T08:24:37+00:00

Using C line continuation inside format strings is error prone. Clean up the unintended whitespace introduced by misuse of \. Neaten correctly used line continations as well for consistency. drivers/scsi/arcmsr/arcmsr_hba.c has these errors as well, but arcmsr needs a lot more work and the driver should likely be moved to staging instead.

[SCSI] mptfusion: Support SAS2.0 Devices with SAS1.0 Controllers

2011-02-12T19:57:28+00:00

SAS1.0 Controller was not able to detect SAS2.0 Expanders due to Link RATE detection was limited to 1.5 Gbps and 3.0 Gbps for SAS1 controllers. Added detection for 6.0 Gbps link. Now, user can mix-up 6.0 Gpbs links with SAS1.0 controller. e.g SAS1.0 HBA <----> SAS2.0 Expander <------> SAS2.0 Expander <--------> SAS1.0 Drive.
