* dmi: prevent linked list corruptionJean Delvare2008-02-23
| | | | | | | | | | | | | | | | | | | Adding the same item to a given linked list more than once is guaranteed to break and corrupt the list. This is however what we do in dmi_scan since commit 79da4721117fcf188b4b007b775738a530f574da ("x86: fix DMI out of memory problems"). Given that there is absolutely no interest in saving empty OEM strings anyway, I propose the simple and efficient fix below: we discard the empty OEM strings altogether.

* NBD: make nbd default to deadline I/O schedulerPaul Clements2008-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | NBD doesn't work well with CFQ (or AS) schedulers, so let's default to something else. The two problems I have experienced with nbd and cfq are: 1) nbd hangs with cfq on RHEL 5 (2.6.18) -- this may well have been fixed There's a similar debian bug that has been filed as well: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=447638 There have been posts to nbd-general mailing list about problems with cfq and nbd also. 2) nbd performs about 10% better (the last time I tested) with deadline vs. cfq (the overhead of cfq doesn't provide much advantage to nbd [not being a real disk], and you end up going through the I/O scheduler on the nbd server anyway, so it makes sense that deadline is better with nbd) Signed-off-by: Paul Clements <paul.clements@steeleye.com> Cc: Jens Axboe <jens.axboe@oracle.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* spi: pxa2xx_spi clock polarity fixNed Forrester2008-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | 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: Ned Forrester <nforrester@whoi.edu> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Cc: Russell King <rmk@arm.linux.org.uk> Cc: <stable@kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* atmel_spi: fix clock polarityAtsushi Nemoto2008-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * [SCSI] aic94xx: fix sequencer hang on error recoveryJames Bottomley2008-02-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * [SCSI] stex: stex_internal_copy should be called with sg_count in struct st_ccbFUJITA Tomonori2008-02-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * [SCSI] stex: stex_direct_copy shouldn't call dma_map_sgFUJITA Tomonori2008-02-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * [SCSI] libsas: fix error handlingJames Bottomley2008-02-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: James Bottomley <James.Bottomley@HansenPartnership.com>

* | PM: Introduce PM_EVENT_HIBERNATE callback stateRafael J. Wysocki2008-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Rafael J.

We need this information to test some bit so we know if TjMax is 100C or 85C. Intel claims this works for mobiles only, respect that and set for desktops the TjMax to 100C.

So I assume that there's no such Ts0p sensor in this model (please confirm, anyone). If there's the case, then we need a new set of sensors defined for MacBook2.
