hwmon: (asus_atk0110) Add quirk for Asus M5A78L

2012-09-14T17:00:34Z

commit 43ca6cb28c871f2fbad10117b0648e5ae3b0f638 upstream. The old interface is bugged and reads the wrong sensor when retrieving the reading for the chassis fan (it reads the CPU sensor); the new interface works fine.

xen/pciback: Fix proper FLR steps.

2012-09-14T17:00:33Z

commit 80ba77dfbce85f2d1be54847de3c866de1b18a9a upstream. When we do FLR and save PCI config we did it in the wrong order. The end result was that if a PCI device was unbind from its driver, then binded to xen-pciback, and then back to its driver we would get: > lspci -s 04:00.0 04:00.0 Ethernet controller: Intel Corporation 82574L Gigabit Network Connection 13:42:12 # 4 :~/ > echo "0000:04:00.0" > /sys/bus/pci/drivers/pciback/unbind > modprobe e1000e e1000e: Intel(R) PRO/1000 Network Driver - 2.0.0-k e1000e: Copyright(c) 1999 - 2012 Intel Corporation. e1000e 0000:04:00.0: Disabling ASPM L0s L1 e1000e 0000:04:00.0: enabling device (0000 -> 0002) xen: registering gsi 48 triggering 0 polarity 1 Already setup the GSI :48 e1000e 0000:04:00.0: Interrupt Throttling Rate (ints/sec) set to dynamic conservative mode e1000e: probe of 0000:04:00.0 failed with error -2 This fixes it by first saving the PCI configuration space, then doing the FLR.

xen: Use correct masking in xen_swiotlb_alloc_coherent.

2012-09-14T17:00:33Z

commit b5031ed1be0aa419250557123633453753181643 upstream. When running 32-bit pvops-dom0 and a driver tries to allocate a coherent DMA-memory the xen swiotlb-implementation returned memory beyond 4GB. The underlaying reason is that if the supplied driver passes in a DMA_BIT_MASK(64) ( hwdev->coherent_dma_mask is set to 0xffffffffffffffff) our dma_mask will be u64 set to 0xffffffffffffffff even if we set it to DMA_BIT_MASK(32) previously. Meaning we do not reset the upper bits. By using the dma_alloc_coherent_mask function - it does the proper casting and we get 0xfffffffff. This caused not working sound on a system with 4 GB and a 64-bit compatible sound-card with sets the DMA-mask to 64bit. On bare-metal and the forward-ported xen-dom0 patches from OpenSuse a coherent DMA-memory is always allocated inside the 32-bit address-range by calling dma_alloc_coherent_mask. This patch adds the same functionality to xen swiotlb and is a rebase of the original patch from Ronny Hegewald which never got upstream b/c the underlaying reason was not understood until now.

i2c-designware: Fix build error if CONFIG_I2C_DESIGNWARE_PLATFORM=y && CONFIG_I2C_DESIGNWARE_PCI=y

2012-09-14T17:00:32Z

commit e68bb91baa0bb9817567bd45d560919e8e26373b upstream. This patch adds config I2C_DESIGNWARE_CORE in Kconfig, and let I2C_DESIGNWARE_PLATFORM and I2C_DESIGNWARE_PCI select I2C_DESIGNWARE_CORE. Because both I2C_DESIGNWARE_PLATFORM and I2C_DESIGNWARE_PCI can be built as built-in or module, we also need to export the functions in i2c-designware-core. This fixes below build error when CONFIG_I2C_DESIGNWARE_PLATFORM=y && CONFIG_I2C_DESIGNWARE_PCI=y: LD drivers/i2c/busses/built-in.o drivers/i2c/busses/i2c-designware-pci.o: In function `i2c_dw_clear_int': i2c-designware-core.c:(.text+0xa10): multiple definition of `i2c_dw_clear_int' drivers/i2c/busses/i2c-designware-platform.o:i2c-designware-platdrv.c:(.text+0x928): first defined here drivers/i2c/busses/i2c-designware-pci.o: In function `i2c_dw_init': i2c-designware-core.c:(.text+0x178): multiple definition of `i2c_dw_init' drivers/i2c/busses/i2c-designware-platform.o:i2c-designware-platdrv.c:(.text+0x90): first defined here drivers/i2c/busses/i2c-designware-pci.o: In function `dw_readl': i2c-designware-core.c:(.text+0xe8): multiple definition of `dw_readl' drivers/i2c/busses/i2c-designware-platform.o:i2c-designware-platdrv.c:(.text+0x0): first defined here drivers/i2c/busses/i2c-designware-pci.o: In function `i2c_dw_isr': i2c-designware-core.c:(.text+0x724): multiple definition of `i2c_dw_isr' drivers/i2c/busses/i2c-designware-platform.o:i2c-designware-platdrv.c:(.text+0x63c): first defined here drivers/i2c/busses/i2c-designware-pci.o: In function `i2c_dw_xfer': i2c-designware-core.c:(.text+0x4b0): multiple definition of `i2c_dw_xfer' drivers/i2c/busses/i2c-designware-platform.o:i2c-designware-platdrv.c:(.text+0x3c8): first defined here drivers/i2c/busses/i2c-designware-pci.o: In function `i2c_dw_is_enabled': i2c-designware-core.c:(.text+0x9d4): multiple definition of `i2c_dw_is_enabled' drivers/i2c/busses/i2c-designware-platform.o:i2c-designware-platdrv.c:(.text+0x8ec): first defined here drivers/i2c/busses/i2c-designware-pci.o: In function `dw_writel': i2c-designware-core.c:(.text+0x124): multiple definition of `dw_writel' drivers/i2c/busses/i2c-designware-platform.o:i2c-designware-platdrv.c:(.text+0x3c): first defined here drivers/i2c/busses/i2c-designware-pci.o: In function `i2c_dw_xfer_msg': i2c-designware-core.c:(.text+0x2e8): multiple definition of `i2c_dw_xfer_msg' drivers/i2c/busses/i2c-designware-platform.o:i2c-designware-platdrv.c:(.text+0x200): first defined here drivers/i2c/busses/i2c-designware-pci.o: In function `i2c_dw_enable': i2c-designware-core.c:(.text+0x9c8): multiple definition of `i2c_dw_enable' drivers/i2c/busses/i2c-designware-platform.o:i2c-designware-platdrv.c:(.text+0x8e0): first defined here drivers/i2c/busses/i2c-designware-pci.o: In function `i2c_dw_read_comp_param': i2c-designware-core.c:(.text+0xa24): multiple definition of `i2c_dw_read_comp_param' drivers/i2c/busses/i2c-designware-platform.o:i2c-designware-platdrv.c:(.text+0x93c): first defined here drivers/i2c/busses/i2c-designware-pci.o: In function `i2c_dw_disable': i2c-designware-core.c:(.text+0x9dc): multiple definition of `i2c_dw_disable' drivers/i2c/busses/i2c-designware-platform.o:i2c-designware-platdrv.c:(.text+0x8f4): first defined here drivers/i2c/busses/i2c-designware-pci.o: In function `i2c_dw_func': i2c-designware-core.c:(.text+0x710): multiple definition of `i2c_dw_func' drivers/i2c/busses/i2c-designware-platform.o:i2c-designware-platdrv.c:(.text+0x628): first defined here drivers/i2c/busses/i2c-designware-pci.o: In function `i2c_dw_disable_int': i2c-designware-core.c:(.text+0xa18): multiple definition of `i2c_dw_disable_int' drivers/i2c/busses/i2c-designware-platform.o:i2c-designware-platdrv.c:(.text+0x930): first defined here make[3]: *** [drivers/i2c/busses/built-in.o] Error 1 make[2]: *** [drivers/i2c/busses] Error 2 make[1]: *** [drivers/i2c] Error 2 make: *** [drivers] Error 2 Signed-off-by: Axel Lin Signed-off-by: Jean Delvare Tested-by: Jiri Slaby Signed-off-by: Greg Kroah-Hartman

SCSI: Fix 'Device not ready' issue on mpt2sas

2012-09-14T17:00:32Z

commit 14216561e164671ce147458653b1fea06a4ada1e upstream. This is a particularly nasty SCSI ATA Translation Layer (SATL) problem. SAT-2 says (section 8.12.2) if the device is in the stopped state as the result of processing a START STOP UNIT command (see 9.11), then the SATL shall terminate the TEST UNIT READY command with CHECK CONDITION status with the sense key set to NOT READY and the additional sense code of LOGICAL UNIT NOT READY, INITIALIZING COMMAND REQUIRED; mpt2sas internal SATL seems to implement this. The result is very confusing standby behaviour (using hdparm -y). If you suspend a drive and then send another command, usually it wakes up. However, if the next command is a TEST UNIT READY, the SATL sees that the drive is suspended and proceeds to follow the SATL rules for this, returning NOT READY to all subsequent commands. This means that the ordering of TEST UNIT READY is crucial: if you send TUR and then a command, you get a NOT READY to both back. If you send a command and then a TUR, you get GOOD status because the preceeding command woke the drive. This bit us badly because commit 85ef06d1d252f6a2e73b678591ab71caad4667bb Author: Tejun Heo Date: Fri Jul 1 16:17:47 2011 +0200 block: flush MEDIA_CHANGE from drivers on close(2) Changed our ordering on TEST UNIT READY commands meaning that SATA drives connected to an mpt2sas now suspend and refuse to wake (because the mpt2sas SATL sees the suspend *before* the drives get awoken by the next ATA command) resulting in lots of failed commands. The standard is completely nuts forcing this inconsistent behaviour, but we have to work around it. The fix for this is twofold: 1. Set the allow_restart flag so we wake the drive when we see it has been suspended 2. Return all TEST UNIT READY status directly to the mid layer without any further error handling which prevents us causing error handling which may offline the device just because of a media check TUR.

SCSI: mpt2sas: Fix for Driver oops, when loading driver with max_queue_depth command line option to a very small value

2012-09-14T17:00:25Z

commit 338b131a3269881c7431234855c93c219b0979b6 upstream. If the specified max_queue_depth setting is less than the expected number of internal commands, then driver will calculate the queue depth size to a negitive number. This negitive number is actually a very large number because variable is unsigned 16bit integer. So, the driver will ask for a very large amount of memory for message frames and resulting into oops as memory allocation routines will not able to handle such a large request. So, in order to limit this kind of oops, The driver need to set the max_queue_depth to a scsi mid layer's can_queue value. Then the overall message frames required for IO is minimum of either (max_queue_depth plus internal commands) or the IOC global credits.
