Fixes a sequencing bug in spi driver pxa2xx_spi.c in which the chip select for a transfer may be asserted before the clock polarity is set on the interface. As a result of this bug, the clock signal may have the wrong polarity at transfer start, so it may need to make an extra half transition before the intended clock/data signals begin. (This probably means all transfers are one bit out of sequence.) This only occurs on the first transfer following a change in clock polarity in systems using more than one more than one such polarity. The fix assures that the clock mode is properly set before asserting chip select. This bug was introduced in a patch merged on 2006/12/10, kernel 2.6.20. The patch defines an additional bit in: include/asm-arm/arch-pxa/regs-ssp.h for 2.6.25 and newer kernels but this addition must be made in: include/asm-arm/arch-pxa/pxa-regs.h for kernels between 2.6.20 and 2.6.24, inclusive Signed-off-by: NNed Forrester <nforrester@whoi.edu> Signed-off-by: NDavid Brownell <dbrownell@users.sourceforge.net> Cc: Russell King <rmk@arm.linux.org.uk> Cc: <stable@kernel.org> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

The atmel_spi driver does not initialize clock polarity correctly (except for at91rm9200 CS0 channel) in some case. The atmel_spi driver uses gpio-controlled chipselect. OTOH spi clock signal is controlled by CSRn.CPOL bit, but this register controls clock signal correctly only in 'real transfer' duration. At the time of cs_activate() call, CSRn.CPOL will be initialized correctly, but the controller do not know which channel is to be used next, so clock signal will stay at the inactive state of last transfer. If clock polarity of new transfer and last transfer was differ, new transfer will start with wrong clock signal state. For example, if you started SPI MODE 2 or 3 transfer after SPI MODE 0 or 1 transfer, the clock signal state at the assertion of chipselect will be low. Of course this will violates SPI transfer. This patch is short term solution for this problem. It makes all CSRn.CPOL match for the transfer before activating chipselect. For longer term, the best fix might be to let NPCS0 stay selected permanently in MR and overwrite CSR0 with to the new slave's settings before asserting CS.

2.6.25-rc1 percpu changes broke CONFIG_DEBUG_PREEMPT's per_cpu checking on several architectures. On s390, sparc64 and x86 it's been weakened to not checking at all; whereas on powerpc64 it's become too strict, issuing warnings from __raw_get_cpu_var in io_schedule and init_timer for example. Fix this by weakening powerpc's __my_cpu_offset to use the non-checking local_paca instead of get_paca (which itself contains such a check); and strengthening the generic my_cpu_offset to go the old slow way via smp_processor_id when CONFIG_DEBUG_PREEMPT (debug_smp_processor_id is where all the knowledge of what's correct when lives).

During the last step of hibernation in the "platform" mode (with the help of ACPI) we use the suspend code, including the devices' ->suspend() methods, to prepare the system for entering the ACPI S4 system sleep state. But at least for some devices the operations performed by the ->suspend() callback in that case must be different from its operations during regular suspend. For this reason, introduce the new PM event type PM_EVENT_HIBERNATE and pass it to the device drivers' ->suspend() methods during the last phase of hibernation, so that they can distinguish this case and handle it as appropriate. Modify the drivers that handle PM_EVENT_SUSPEND in a special way and need to handle PM_EVENT_HIBERNATE in the same way. These changes are necessary to fix a hibernation regression related to the i915 driver (ref. http://lkml.org/lkml/2008/2/22/488). Signed-off-by: NRafael J.

The clear nexus I_T and clear nexus I_T_L functions in the aic94xx specify the SUSPEND_TX flag which causes the sequencer to be suspended until it receives a RESUME_TX. Unfortunately, nothing ever sends the resume, so the sequencer on the link is stopped forever, leading to eventual timeouts and I/O errors. Since clear nexus commands are only executed as part of error recovery, it's perfectly fine to keep the sequencer running on the link ... as soon as the recovery function is completed, we'll send it the commands to retry.

stex_internal_copy copies an in-kernel buffer to a sg list by using scsi_kmap_atomic_sg. Some functions calls stex_internal_copy with sg_count in struct st_ccb, which is the value that dma_map_sg returned. However it might be shorter than the actual number of sg entries (if the IOMMU merged the sg entries). scsi_kmap_atomic_sg doesn't see sg->dma_length so stex_internal_copy should be called with the actual number of sg entries (i.e. scsi_sg_count), because if the sg entries were merged, stex_direct_copy wrongly think that the data length in the sg list is shorter than the actual length.

stex_direct_copy copies an in-kernel buffer to a sg list in order to spoof some SCSI commands. stex_direct_copy calls dma_map_sg and then stex_internal_copy with the value that dma_map_sg returned. It calls scsi_kmap_atomic_sg to copy data. scsi_kmap_atomic_sg doesn't see sg->dma_length so if dma_map_sg merges sg entries, stex_internal_copy gets the smaller number of sg entries than the acutual number, which means it wrongly think that the data length in the sg list is shorter than the actual length. stex_direct_copy shouldn't call dma_map_sg and it doesn't need since this code path doesn't involve dma transfers. This patch removes stex_direct_copy and simply calls stex_internal_copy with the actual number of sg entries.

The libsas error handler has two fairly fatal bugs 1. scsi_sas_task_done calls scsi_eh_finish_cmd() too early. This happens if the task completes after it has been aborted but before the error handler starts up. Because scsi_eh_finish_cmd() decrements host_failed and adds the task to the done list, the error handler start check (host_failed == host_busy) never passes and the eh never starts. 2. The multiple task completion paths sas_scsi_clear_queue_... all simply delete the task from the error queue. This causes it to disappear into the ether, since a command must be placed on the done queue to be finished off by the error handler. This behaviour causes the HBA to hang on pending commands. Fix 1. by moving the SAS_TASK_STATE_ABORTED check to an exit clause at the top of the routine and calling ->scsi_done() unconditionally (it is a nop if the timer has fired). This keeps the task in the error handling queue until the eh starts. Fix 2. by making sure every task goes through task complete followed by scsi_eh_finish_cmd(). Tested this by firing resets across a disk running a hammer test (now it actually survives without hanging the system) Signed-off-by: NJames Bottomley <James.Bottomley@HansenPartnership.com>
