2013-12-19[SCSI] hpsa: prevent stalled i/oStephen M. Cameron
If a fifo full condition is encountered, i/o requests will stack up in the h->reqQ queue. The only thing which empties this queue is start_io, which only gets called when new i/o requests come in. If none are forthcoming, i/o in h->reqQ will be stalled. To fix this, whenever fifo full condition is encountered, this is recorded, and the interrupt handler examines this to see if a fifo full condition was recently encountered when a command completes and will call start_io to prevent i/o's in h->reqQ from getting stuck. I've only ever seen this problem occur when running specialized test programs that pound on the the CCISS_PASSTHRU ioctl. Signed-off-by: Stephen M.

2013-12-19[SCSI] hpsa: cap CCISS_PASSTHRU at 20 concurrent commands.Stephen M. Cameron
Cap CCISS_BIG_PASSTHRU as well. If an attempt is made to exceed this, ioctl() will return -1 with errno == EAGAIN. This is to prevent a userland program from exhausting all of pci_alloc_consistent memory. I've only seen this problem when running a special test program designed to provoke it. 20 concurrent commands via the passthru ioctls (not counting SG_IO) should be more than enough.

2013-12-16[SCSI] hpsa: add 5 second delay after doorbell resetStephen M. Cameron
The hardware guys tell us that after initiating a software reset via the doorbell register we need to wait 5 seconds before attempting to talk to the board *at all*. This means that we cannot watch the board to verify it transitions from "ready" to to "not ready" then back "ready", since this transition will most likely happen during those 5 seconds (though we can still verify the reset happens by watching the "driver version" field get cleared.)

2013-12-16[SCSI] sr: use block layer runtime PMAaron Lu
Migrate sr to make use of block layer runtime PM. Accordingly, the SCSI bus layer runtime PM callback is simplified as all SCSI drivers implementing runtime PM now use the block layer's request-based mechanism. Note that due to the device will be polled by kernel at a constant interval, if the autosuspend delay is set longer than the polling interval then the device will never suspend.

2013-12-16[SCSI] scsi_debug: simplify creation and destruction of driver attribute filesAkinobu Mita
Instead of repeatedly calling driver_create_file() to create driver attribute files, This achieves the same thing by constructing an array of driver_attribute and setting it to bus_type->drv_groups. This change simplifies both creation and destruction of the attribute files, and also removes sparse warning caused by driver_attributes which are unnecessarily declared as global.

For NUMA systems, initializing the blk-mq layer and using per node hctx. We initialize submit queues to 1, while blk-mq nr_hw_queues is initialized to the number of NUMA nodes. This makes the null_init_hctx function overwrite memory outside of what it allocated. In my case it lead to writing garbage into struct request_queue's mq_map.

Now they behave properly like their ipv4 counterparts. From Kamala R. 5) Several drivers advertise the NETIF_F_FRAGLIST capability, but really do not support this feature and will send garbage packets if fed fraglist SKBs. From Eric Dumazet. 6) Fix long standing user triggerable BUG_ON over loopback in RDS protocol stack, from Venkat Venkatsubra. 7) Several not so common code paths can potentially try to invoke packet scheduler actions that might be NULL without checking. Shore things up by either 1) defining a method as mandatory and erroring on registration if that method is NULL 2) defininig a method as optional and the registration function hooks up a default implementation when NULL is seen. From Jamal Hadi Salim. 8) Fix fragment detection in xen-natback driver, from Paul Durrant. 9) Kill dangling enter_memory_pressure method in cg_proto ops, from Eric W Biederman. 10) SKBs that traverse namespaces should have their local_df cleared, from Hannes Frederic Sowa. 11) IOCB file position is not being updated by macvtap_aio_read() and tun_chr_aio_read(). From Zhi Yong Wu. 12) Don't free virtio_net netdev before releasing all of the NAPI instances. From Andrey Vagin. 13) Procfs entry leak in xt_hashlimit, from Sergey Popovich. 14) IPv6 routes that are no cached routes should not count against the garbage collection limits.

2013-12-13dm space map: disallow decrementing a reference count below zeroJoe Thornber
The old behaviour, returning -EINVAL if a ref_count of 0 would be decremented, was removed in commit f722063 ("dm space map: optimise sm_ll_dec and sm_ll_inc"). To fix this regression we return an error code from the mutator function pointer passed to sm_ll_mutate() and have dec_ref_count() return -EINVAL if the old ref_count is 0. Add a DMERR to reflect the potential seriousness of this error. Also, add missing dm_tm_unlock() to sm_ll_mutate()'s error path. With this fix the following dmts regression test now passes: dmtest run --suite cache -n /metadata_use_kernel/ The next patch fixes the higher-level dm-array code that exposed this regression.

2013-12-12mfd/rtc: s5m: fix register updating by adding regmap for RTCKrzysztof Kozlowski
Rename old regmap field of "struct sec_pmic_dev" to "regmap_pmic" and add new regmap for RTC. On S5M8767A registers were not properly updated and read due to usage of the same regmap as the PMIC. This could be observed in various hangs, e.g. in infinite loop during waiting for UDR field change. On this chip family the RTC has different I2C address than PMIC so additional regmap is needed.

Probably the author wanted to assign "struct sec_pmic_dev.regmap", which has the correct type. Also, as "rtc" doesn't make much sense as a name for a regmap, rename it to "regmap".

Again, OMAP regressions due to move to DT is the bulk of the changes here, but this should be the last of it for 3.13. There are also a handful of OMAP hwmod changes (power management, reset handling) for USB on OMAP3 that fixes some longish-standing bugs around USB resets. There are a couple of other changes that also add up line count a bit: One is a long-standing bug with the keyboard layout on one of the PXA platforms. The other is a fix for highbank that moves their power-off/reset button handling to be done in-kernel since relying on userspace to handle it was fragile and awkward" * tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: sun6i: dt: Fix interrupt trigger types ARM: sun7i: dt: Fix interrupt trigger types MAINTAINERS: merge IMX6 entry into IMX ARM: tegra: add missing break to fuse initialization code ARM: pxa: prevent PXA270 occasional reboot freezes ARM: pxa: tosa: fix keys mapping ARM: OMAP2+: omap_device: add fail hook for runtime_pm when bad data is detected ARM: OMAP2+: hwmod: Fix usage of invalid iclk / oclk when clock node is not present ARM: OMAP3: hwmod data: Don't prevent RESET of USB Host module ARM: OMAP2+: hwmod: Fix SOFTRESET logic ARM: OMAP4+: hwmod data: Don't prevent RESET of USB Host module ARM: dts: Fix booting for secure omaps ARM: OMAP2+: Fix the machine entry for am3517 ARM: dts: Fix missing entries for am3517 ARM: OMAP2+: Fix overwriting hwmod data with data from device tree ARM: davinci: Fix McASP mem resource names ARM: highbank: handle soft poweroff and reset key events ARM: davinci: fix number of resources passed to davinci_gpio_register() gpio: davinci: fix check for unbanked gpio
2013-12-12mtd: nand: pxa3xx: Use info->use_dma to release DMA resourcesEzequiel Garcia
In commit: commit 62e8b851783138a11da63285be0fbf69530ff73d Author: Ezequiel Garcia <ezequiel.garcia@free-electrons.com> Date: Fri Oct 4 15:30:38 2013 -0300 mtd: nand: pxa3xx: Allocate data buffer on detected flash size the way the buffer is allocated was changed: the first READ_ID is issued with a small kmalloc'ed buffer. Only once the flash page size is detected the DMA buffers are allocated, and info->use_dma is set. Currently, if the device detection fails, the driver checks the 'use_dma' module parameter and tries to release unallocated DMA resources. Fix this by checking the proper indicator of the DMA allocation, which is 'info->use_dma'.

2013-12-12i2c: mux: Inherit retry count and timeout from parent for muxed busElie De Brauwer
If a muxed i2c bus gets created the default retry count and timeout of the muxed bus is zero. Hence it it possible that you end up with a situation where the parent controller sets a default retry count and timeout which gets applied and used while the muxed bus (using the same controller) has a default retry count of zero and a default timeout of 1s (set in i2c_add_adapter()). This can be solved by initializing the retry count and timeout of the muxed bus with the values used by the the parent at creation time.
