commit 01350d05 upstream. If a physical device exposed to the OS by hpsa is replaced (e.g. one hot plug tape drive is replaced by another, or a tape drive is placed into "OBDR" mode in which it acts like a CD-ROM device) and a rescan is initiated, the replaced device will be added to the SCSI midlayer with target and lun numbers set to -1. After that, a panic is likely to ensue. When a physical device is replaced, the lun and target number should be preserved. Signed-off-by:

commit 0b0e1d6c upstream. The test to detect OBDR ("One Button Disaster Recovery") cd-rom devices was comparing against uninitialized data. Fixed by moving the test for the device to where the inquiry data is collected, and uninitialized variable altogether as it wasn't really being used. Signed-off-by:

commit ee33e2b7 upstream. The unsolicited frame control infrastructure requires a table of dma addresses for the hardware to lookup the frame buffer location by an index. The hardware expects the elements of this table to be 64-bit quantities, so we cannot reference these elements as dma_addr_t. All unsolicited frame protocols are affected, particularly SATA-PIO and SMP which prevented direct-attached SATA drives and expander-attached drives to not be discovered. Reported-by:

commit f88657ce upstream. Some of the flags are OS/arch dependent we add a 9p protocol value which maps to asm-generic/fcntl.h values in Linux Based on the original patch from Venkateswararao Jujjuri <jvrao@linux.vnet.ibm.com> [extra comments from author as to why this needs to go to stable: Earlier for different operation such as open we used the values of open flag as defined by the OS. But some of these flags such as O_DIRECT are arch dependent. So if we have the 9p client and server running on different architectures, we end up with client sending client architecture value of these open flag and server will try to map these values to what its architecture states. For ex: O_DIRECT on a x86 client maps to #define O_DIRECT 00040000 Where as on sparc server it will maps to #define O_DIRECT 0x100000 Hence we need to map these open flags to OS/arch independent flag values. Getting these changes to an early version of kernel ensures us that we work with different combination of client and server. We should ideally backport this patch to all possible kernel version.] Signed-off-by:

commit 8f9c9127 upstream. We can only sort the _TSS return package if there is no _PSS in the same scope. This is because if _PSS is present, the ACPI specification dictates that the _TSS Power Dissipation field is to be ignored, and therefore some BIOSs leave garbage values in the _TSS Power field(s). In this case, it is best to just return the _TSS package as-is. Reported-by:

commit fc61ccd3 upstream. dvb_usb_device_init calls the frontend_attach method of this driver which uses vp7045_usb_ob. In order to have a buffer ready in vp7045_usb_op, it has to be allocated before that happens. Luckily we can use the whole private data as the buffer as it gets separately allocated on the heap via kzalloc in dvb_usb_device_init and is thus apt for use via usb_control_msg. This fixes a BUG: unable to handle kernel paging request at 0000000000001e78 reported by Tino Keitel and diagnosed by Dan Carpenter. Tested-by:

commit de4ed0c1 upstream. The nuvoton-cir driver was storing up consecutive pulse-pulse and space-space samples internally, for no good reason, since ir_raw_event_store_with_filter() already merges back to back like samples types for us. This should also fix a regression introduced late in 3.0 that related to a timeout change, which actually becomes correct when coupled with this change. Tested with RC6 and RC5 on my own nuvoton-cir hardware atop vanilla 3.0.0, after verifying quirky behavior in 3.0 due to the timeout change. Reported-by:

commit 27a7b260 upstream. 0.90 metadata uses an unsigned 32bit number to count the number of kilobytes used from each device. This should allow up to 4TB per device. However we multiply this by 2 (to get sectors) before casting to a larger type, so sizes above 2TB get truncated. Also we allow rdev->sectors to be larger than 4TB, so it is possible for the array to be resized larger than the metadata can handle. So make sure rdev->sectors never exceeds 4TB when 0.90 metadata is in used. Also the sanity check at the end of super_90_load should include level 1 as it used ->size too. (RAID0 and Linear don't use ->size at all). Reported-by:

commit 94007751 upstream. On the last close of an 'md' device which as been stopped, the device is destroyed and in particular the request_queue is freed. The free is done in a separate thread so it might happen a short time later. __blkdev_put calls bdev_inode_switch_bdi *after* ->release has been called. Since commit f758eeab bdev_inode_switch_bdi will dereference the 'old' bdi, which lives inside a request_queue, to get a spin lock. This causes the last close on an md device to sometime take a spin_lock which lives in freed memory - which results in an oops. So move the called to bdev_inode_switch_bdi before the call to ->release.

commit 897a6a1a upstream. The TNET variant of DaVinci compiles some code that it shares with other DaVinci variants, however it has a V6 CPU rather than an ARM926T, thus the hardcoded call to arm926_flush_kern_cache_all() in sleep.S will obviously fail, and we need to build with the v6_flush_kern_cache_all() call instead.

commit 810198bc upstream. DA850/OMAP-L138 EMAC driver uses random mac address instead of a fixed one because the mac address is not stuffed into EMAC platform data. This patch provides a function which reads the mac address stored in SPI flash (registered as MTD device) and populates the EMAC platform data. The function which reads the mac address is registered as a callback which gets called upon addition of MTD device. NOTE: In case the MAC address stored in SPI flash is erased, follow the instructions at [1] to restore it. [1] http://processors.wiki.ti.com/index.php/GSG:_OMAP-L138_DVEVM_Additional_Procedures#Restoring_MAC_address_on_SPI_Flash Modifications in v2: Guarded registering the mtd_notifier only when MTD is enabled. Earlier this was handled using mtd_has_partitions() call, but this has been removed in Linux v3.0. Modifications in v3: a. Guarded da850_evm_m25p80_notify_add() function and da850evm_spi_notifier structure with CONFIG_MTD macros. b. Renamed da850_evm_register_mtd_user() function to da850_evm_setup_mac_addr() and removed the struct mtd_notifier argument to this function. c. Passed the da850evm_spi_notifier structure to register_mtd_user() function. Modifications in v4: Moved the da850_evm_setup_mac_addr() function within the first CONFIG_MTD ifdef construct.

commit bb9ea778 upstream. I was intrigued by the fact that the clock stood still on the Integrator, but it wasn't strange at all, because the timer was set up all wrong and probably has been for a while. With this patch the clock starts ticking again: make the timer periodic (reload), |= on the divisor bit and load the timer before starting it. Signed-off-by:

The correct way is to pass in 'dom0_max_vcpus=1' on the Xen hypervisor line and the kernel will patch itself to be a UP kernel.

commit 49bb1e61 upstream. This patch fixes the problem in sdhci-s3c host driver for Samsung Soc's. During the card identification stage the mmc core driver enumerates for the best bus width in combination with the highest available data rate. It starts enumerating from the highest bus width (8) to lowest width (1). In case of few MMC cards the 4-bit bus enumeration fails and tries the 1-bit bus enumeration. When switched to 1-bit bus mode the host driver has to clear the previous bus width setting and apply the new setting. The current patch will clear the previous bus mode and apply the new mode setting. Signed-off-by:

commit 50a50f92 upstream. The default multithread workqueue can cause the same work to be executed concurrently on a different CPUs. This isn't really suitable for clock gating as it might already gated the clock and gating it twice results both host->clk_old and host->ios.clock to be set to 0. To prevent this from happening we use system_nrt_wq instead. Signed-off-by:

commit 778e277c upstream. We have seen at least two different races when clock gating kicks in in a middle of ios structure update. First one happens when ios->clock is changed outside of aggressive clock gating framework, for example via mmc_set_clock(). The race might happen when we run following code: mmc_set_ios(): ... if (ios->clock > 0) mmc_set_ungated(host); Now if gating kicks in right after the condition check we end up setting host->clk_gated to false even though we have just gated the clock. Next time a request is started we try to ungate and restore the clock in mmc_host_clk_hold(). However since we have host->clk_gated set to false the original clock is not restored. This eventually will cause the host controller to hang since its clock is disabled while we are trying to issue a request. For example on Intel Medfield platform we see: [ 13.818610] mmc2: Timeout waiting for hardware interrupt.
