* r8169: PHY power-on fixRoger So2007-08-06
| | | | | | | | | | | | | | | Fix extracted from Realtek's driver (8.002.00/20070713) for the PHY attached to 8111/8168b chipsets. The check against mac_version is just usual paranoia during the bugfix period of the kernel cycle. -- FR Tested on Asus M2A-VM motherboard by Roger So. No regression on my Asrock 945G DVI either (built-in 8168 + 2x8169).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fully unify all of the DMA ops so that subordinate bus types to the DMA operation providers (such as ebus, isa, of_device) can work transparently. Basically, we just make sure that for every system device we create, the dev->archdata 'iommu' and 'stc' fields are filled in. Then we have two platform variants of the DMA ops, one for SUN4U which actually programs the real hardware, and one for SUN4V which makes hypervisor calls. This also fixes the crashes in parport_pc on sparc64, reported by Meelis Roos. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All of these drivers use a silly: struct all_info { struct fb_info info; struct foo_par par; }; struct all_info *all = kzalloc(sizeof(*all), GFP_KERNEL); all->info.par = &all->par; etc. etc. code sequence, basically replicating the provided framebuffer_alloc()/framebuffer_release(), and doing it badly. Not only is this massive code duplication, it also caused a bug in that we weren't setting the fb_info->device pointer which results in an OOPS when fb_is_primary_device() runs. Fix all of this by using framebuffer_{alloc,release}() and passing in "&of_device->dev" as the device pointer. Signed-off-by: David S. Miller <davem@davemloft.net>

| * [SCSI] aacraid: fix Sunrise Lake reset handlingSalyzyn, Mark2007-07-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch is *much* smaller than the description. I am attempting to answer to those that want to understand an issue that was reported in May this year. If a Sunrise Lake based card that requires an alternate reset mechanism is set up to ignore the commanded IOP_RESET it reports 0x00000010 (IOP_RESET ignored) instead of 0x3803000F (use alternate reset mechanism to reset all cores), and thus the reset platform function decides to switch to IOP_RESET_ALWAYS because the reset platform function parameters indicate that we *need* to reset the card. IOP_RESET_ALWAYS then responds with the 0x3803000F return code, but alas we treat this as an error instead of using the alternate reset mechanism (put a 0x03 into the register offset 0x38). The reset fails, but the fact that the IOP_RESET_ALWAYS command was issued has put the card in a purposeful shutdown state in preparation for the alternate hardware reset to be applied. Yuck. IOP_RESET is ignored in internal production cards, typically to ensure that we catch all adapter lockup issues without the driver progressing further, so this would not appear to be a field issue and thus this patch was destined to be only in the internal Adaptec source tree. IOP_RESET_ALWAYS is reserved for kexec/kdump/FirmwareUpdate/AutomatedTestFrames so we did not function as expected in any case. Also in the past we have had OEMs specifically request that cards not be resetable after a BlinkLED/FirmwareAssert for one reason or another and To head off the possibility that the Sunrise Lake based cards would suffer a similar fate, we propose the enclosed fix. Yinghai Lu of SUN had a pre-production card with IOP_RESET disabled when he reported an issue to the linux kernel list back in May regarding a kexec problem resulting from this reset being ignore. His fix was to update the Firmware to one that did not ignore the IOP_RESET. Previous kernels did not attempt to reset the adapter and that is why it surfaced as a regression in his hands. The current list of aacraid based cards that use Sunrise Lake: 9005:0285:9005:02b5 Adaptec 5445 9005:0285:9005:02b6 Adaptec 5805 9005:0285:9005:02b7 Adaptec 5085 9005:0285:9005:02c3 Adaptec 51205 9005:0285:9005:02c4 Adaptec 51605 9005:0285:9005:02ce Adaptec 51245 9005:0285:9005:02cf Adaptec 51645 9005:0285:9005:02d0 Adaptec 52445 9005:0285:9005:02d1 Adaptec 5405 9005:0285:9005:02b8 ICP ICP5445SL 9005:0285:9005:02b9 ICP ICP5085SL 9005:0285:9005:02ba ICP ICP5805SL 9005:0285:9005:02c5 ICP ICP5125SL 9005:0285:9005:02c6 ICP ICP5165SL 9005:0285:108e:7aac SUN STK RAID REM 9005:0285:108e:0286 SUN STK RAID INT 9005:0285:108e:0287 SUN STK RAID EXT 9005:0285:108e:7aae SUN STK RAID EM All of these are publicly released with IOP_RESET enabled.

| * [SCSI] aacraid: add SCSI SYNCHONIZE_CACHE range checkingSalyzyn, Mark2007-07-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Customer running an application that issues SYNCHRONIZE_CACHE calls directly noticed the broad stroke of the current implementation in the aacraid driver resulting in multiple applications feeding I/O to the storage causing the issuing application to stall for long periods of time. By only waiting for the current WRITE commands, rather than all commands, to complete; and those that are in range of the SYNCHRONIZE_CACHE call that would associate more tightly with the issuing application before telling the Firmware to flush it's dirty cache, we managed to reduce the stalling. The Firmware itself still flushes all the dirty cache associated with the array ignoring the range, it just does so in a more timely manner.

| * [SCSI] libiscsi: make sure session is not blocked when removing hostMike Christie2007-07-27
| | | | | | | | | | | | | | | | | | | | When we logout we block the session since we are not taking any more commands, but when we call remove host we want to make sure any IO that got queued up and blocked gets failed upwards quickly, so we unblock the session and fail it.

| | | | | | | | | | | | | | | | Eliminate unnecessary PCI dependencies in libsas. It should use generic DMA and struct device like other subsystems. Signed-off-by: Jeff Garzik <jeff@garzik.org> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Apropos this thread http://marc.theaimsgroup.com/?l=linux-scsi&m=115591706804045&w=2 which led to this patch http://www.kernel.org/git/?p=linux/kernel/git/jejb/scsi-rc-fixes-2.6.git;a=commit;h=b2b3c121076961333977f485f0d54c22121df920 We also need to fix sym53c8xx only to bind to the PCI ID if it is of device class PCI_CLASS_STORAGE_SCSI (otherwise it will be the cpqarray RAID device).

| * [SCSI] libsas: SMP request handler shouldn't crash when rphy is NULLDarrick J. Wong2007-07-24
| | | | | | | | | | | | | | | | | | | | sas_smp_handler crashes when smp utils are used with an aic94xx host because certain devices (the sas_host itself, specifically) lack rphy structures. No rphy means no SMP target support, but we shouldn't crash here. Signed-off-by: Darrick J. Wong <djwong@us.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

| | | | | | | | | | | | | | | | We need to newline terminate responses from nodes within the sysfs tree, the Adapter status value reported by the reset adapter node is adjusted. Signed-off-by: Mark Salyzyn <aacraid@adaptec.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
| * [SCSI] aacraid: Fix security holeAlan Cox2007-07-23
| | | | | | | | | | | | | | | | | | | | | | On the SCSI layer ioctl path there is no implicit permissions check for ioctls (and indeed other drivers implement unprivileged ioctls). aacraid however allows all sorts of very admin only things to be done so should check.
