2013-09-11drivers/block/swim.c: remove unnecessary platform_set_drvdata()Jingoo Han
The driver core clears the driver data to NULL after device_release or on probe failure. Thus, it is not needed to manually clear the device driver data to NULL.

2013-09-11cciss: set max scatter gather entries to 32 on P600Mike Miller
At one time we used to set the maximum number of scatter gather elements on all Smart Array controllers to 32. At some point in time the firmware began to write the "appropriate" value for each controller into the config table. The cciss driver would then read that and set h->maxsgentries. h->maxsgentries = readl(&(h->cfgtable->MaxSGElements); On the P600 that value is 544. Under some workloads a significant performance reduction may result. This patch forces the P600 to use only 32 scatter gather elements. Other controllers are not affected.

2013-09-11net: qmi_wwan: add new Qualcomm devicesBjørn Mork
Adding the device list from the Windows driver description files included with a new Qualcomm MDM9615 based device, "Alcatel-sbell ASB TL131 TDD LTE", from China Mobile. This device is tested and verified to work. The others are assumed to work based on using the same Windows driver. Many of these devices support multiple QMI/wwan ports, requiring multiple interface matching entries. All devices are composite, providing a mix of one or more serial, storage or Android Debug Brigde functions in addition to the wwan function. This device list included an update of one previously known device, which was incorrectly assumed to have a Gobi 2K layout. This is corrected.

V7: many changes from a few comments: use linux errno types change I40E_SUCCESS to 0, standardize returns change s32 return values to int use void return values where possible prefer use of int over i40e_status V6: rename Kbuild to Makefile rename i40e_mem[set|cpy] to regular memset/memcpy V5: remove sysfs support from this set, will rearchitect changes from community comments V4: addresses remaining community comments, mostly trivial edits. major sparse based cleanup of possible endian issues removal of most of __func__ references sizeof(*var) instead of sizeof(struct ...) change 'NULL ==' tests to !NULL implement xps use kernel bitshift macros (upper_32_bits, etc) V3: many more individual comments addressed, thanks reviewers! Many other changes due to internal review and development. V2: each patch has individual comments, in general, feedback from the list was applied and addressed. Many changes due to internal review and coding as well. V1: initial send Let me start by saying thanks and we appreciate any time spent by those of you who review and comment on this new driver, and we will attempt to address and respond to all issues brought to our attention. I tried to break the patches up to ease review, but the series should apply and still be bisectable, as the last patch adds the driver to the kernel compile with CONFIG_I40E. This driver is for a brand new bit of silicon that has a different design than other Intel Ethernet silicon, and therefore needed a new driver. The hardware has quite a bit of capability and this driver is only meant to provide basic functionality at first. Future patches will continue to add functionality and bug fixes. This initial release is very early in the product cycle with the intent of getting initial support into the kernel before users have the hardware available to purchase. A software development manual is not ready yet but will be available when the hardware ships. The driver development model and interaction with community submitted patches *will not be any different* than what we are currently doing today. We plan to continue established processes. An associated i40evf driver has been posted for review. List of tools we ran in preparation: way more sparse clean make W=1, W=2 clean checkpatch (almost) clean total: 1 errors, 4 warnings, 30461 lines checked NOTE: Ignored message types: LONG_LINE - issues have been addressed and the remainders are noise. codespell clean smatch (almost) clean with a couple minor warnings coccicheck clean namespacecheck clean allmodconfig clean ppc64 build clean (untested) This driver is a team effort, thank you to Joseph Gasparakis, Shannon Nelson, Anjali Singhai-Jain, Mitch Williams, Neerav Parikh, Vasu Dev, Kavindya Deegala, Yi Zou, and PJ Waskiewicz.

Currently macvlan calls skb_clone in macvlan_broadcast but checks for a NULL return in macvlan_broadcast_one instead. This is needlessly confusing and may lead to bugs introduced later. This patch moves the error check to where the skb_clone call is. The only other caller of macvlan_broadcast_one never passes in a NULL value so it doesn't need the check either.

2013-09-11bnx2x: avoid atomic allocations during initializationMichal Schmidt
During initialization bnx2x allocates significant amounts of memory (for rx data, rx SGEs, TPA pool) using atomic allocations. I received a report where bnx2x failed to allocate SGEs and it had to fall back to TPA-less operation. Let's use GFP_KERNEL allocations during initialization, which runs in process context. Add gfp_t parameters to functions that are used both in initialization and in the receive path. Use an unlikely branch in bnx2x_frag_alloc() to avoid atomic allocation by netdev_alloc_frag(). The branch is taken several thousands of times during initialization, but then never more. Note that fp->rx_frag_size is never greater than PAGE_SIZE, so __get_free_page() can be used here.

2013-09-09clk: only call get_parent if there is oneAlex Elder
In __clk_init(), after a clock is mostly initialized, a scan is done of the orphan clocks to see if the clock being registered is the parent of any of them. This code assumes that any clock that provides a get_parent method actually has at least one parent, and that's not a valid assumption. As a result, an orphan clock with no parent can return *something* as the parent index, and that value is blindly used to dereference the orphan's parent_names[] array (which will be ZERO_SIZE_PTR or NULL). Fix this by ensuring get_parent is only called for orphans with at least one parent. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: Mike Turquette <mturquette@linaro.org>
