This is a third attempt to enable these buttons. The new variable being commit 997daa1b (i.e. hp-wmi: detect "2009 BIOS or later"). Older systems that do not have the 2009 BIOS query method respond with a dummy value, in this case 4. Using that, we can target a fairly narrow group of systems. i.e. old enough to not have HPWMI_FEATURE_QUERY 0xd, but new enough to have HPWMI_BIOS_QUERY 0x9. This group may be further limited if some systems respond with something other than 4 to non-existant feature queries.

The T440s user guide says that when Fn-lock is not active, the *40s' F9 - F12 keys should be mapped to: control-panel, search, show-all-windows and Computer. These keys generate the sofar unused 28 - 31 hotkey scancodes. For the first 2 this nicely matches the icons on the keys, for the latter 2 the icons are somewhat creative, which is why I ended up looking them up in the user manual.

This patch moves data allocated using kzalloc to managed data allocated using devm_kzalloc and cleans now unnecessary kfrees in probe and remove functions. The label sysfs_failed is removed as it is no longer required. Also, linux/device.h is added to make sure the devm_*() routine declarations are unambiguously available. The following Coccinelle semantic patch was used for making the change: @platform@ identifier p, probefn, removefn; @@ struct platform_driver p = { .probe = probefn, .remove = removefn, }; @prb@ identifier platform.probefn, pdev; expression e, e1, e2; @@ probefn(struct platform_device *pdev, ...) { <+... - e = kzalloc(e1, e2) + e = devm_kzalloc(&pdev->dev, e1, e2) ... ?-kfree(e); ...+> } @rem depends on prb@ identifier platform.removefn; expression e; @@ removefn(...) { <... - kfree(e); ...> } Signed-off-by: NHimangi Saraogi <himangi774@gmail.com> Acked-by: NJulia Lawall <julia.lawall@lip6.fr> Signed-off-by: NMatthew Garrett <matthew.garrett@nebula.com>

Remove the code for initializing time if this is first boot. The code for detecting first boot uses undocumented field RTC_TCON in RTC_UDR_CON register. According to S5M8767's datasheet this field is reserved. On S2MPS14 it is not documented at all. On device first boot the registers will be initialized with reset value (2000-01-01 00:00:00). The code might work on S5M8763 but still this does not look like a task for RTC driver.

Right now when people try to report issues in the kernel they send stack dumps to eachother, which looks something like this: [ 6.906437] [<ffffffff811f0e90>] ? backtrace_test_irq_callback+0x20/0x20 [ 6.907121] [<ffffffff84388ce8>] dump_stack+0x52/0x7f [ 6.907640] [<ffffffff811f0ec8>] backtrace_regression_test+0x38/0x110 [ 6.908281] [<ffffffff813596a0>] ? proc_create_data+0xa0/0xd0 [ 6.908870] [<ffffffff870a8040>] ? proc_modules_init+0x22/0x22 [ 6.909480] [<ffffffff810020c2>] do_one_initcall+0xc2/0x1e0 [...] However, most of the text you get is pure garbage. The only useful thing above is the function name. Due to the amount of different kernel code versions and various configurations being used, the kernel address and the offset into the function are not really helpful in determining where the problem actually occured. Too often the result of someone looking at a stack dump is asking the person who sent it for a translation for one or more 'addr2line' translations. Which slows down the entire process of debugging the issue (and really annoying). The decode_stacktrace script is an attempt to make the output more useful and easy to work with by translating all kernel addresses in the stack dump into line numbers. Which means that the stack dump would look like this: [ 635.148361] dump_stack (lib/dump_stack.c:52) [ 635.149127] warn_slowpath_common (kernel/panic.c:418) [ 635.150214] warn_slowpath_null (kernel/panic.c:453) [ 635.151031] _oalloc_pages_slowpath+0x6a/0x7d0 [ 635.152171] ? zone_watermark_ok (mm/page_alloc.c:1728) [ 635.152988] ? get_page_from_freelist (mm/page_alloc.c:1939) [ 635.154766] __alloc_pages_nodemask (mm/page_alloc.c:2766) It's pretty obvious why this is better than the previous stack dump before. Usage is pretty simple: ./decode_stacktrace.sh [vmlinux] [base path] Where vmlinux is the vmlinux to extract line numbers from and base path is the path that points to the root of the build tree, for example: ./decode_stacktrace.sh vmlinux /home/sasha/linux/ < input.log > output.log The stack trace should be piped through it (I, for example, just pipe the output of the serial console of my KVM test box through it).

This patch adds iWARP Port Mapper (IWPM) Version 2 support. The iWARP Port Mapper implementation is based on the port mapper specification section in the Sockets Direct Protocol paper - http://www.rdmaconsortium.org/home/draft-pinkerton-iwarp-sdp-v1.0.pdf Existing iWARP RDMA providers use the same IP address as the native TCP/IP stack when creating RDMA connections. They need a mechanism to claim the TCP ports used for RDMA connections to prevent TCP port collisions when other host applications use TCP ports. The iWARP Port Mapper provides a standard mechanism to accomplish this. Without this service it is possible for RDMA application to bind/listen on the same port which is already being used by native TCP host application. If that happens the incoming TCP connection data can be passed to the RDMA stack with error. The iWARP Port Mapper solution doesn't contain any changes to the existing network stack in the kernel space. All the changes are contained with the infiniband tree and also in user space. The iWARP Port Mapper service is implemented as a user space daemon process. Source for the IWPM service is located at http://git.openfabrics.org/git?p=~tnikolova/libiwpm-1.0.0/.git;a=summary The iWARP driver (port mapper client) sends to the IWPM service the local IP address and TCP port it has received from the RDMA application, when starting a connection. The IWPM service performs a socket bind from user space to get an available TCP port, called a mapped port, and communicates it back to the client. In that sense, the IWPM service is used to map the TCP port, which the RDMA application uses to any port available from the host TCP port space. The mapped ports are used in iWARP RDMA connections to avoid collisions with native TCP stack which is aware that these ports are taken. When an RDMA connection using a mapped port is terminated, the client notifies the IWPM service, which then releases the TCP port. The message exchange between the IWPM service and the iWARP drivers (between user space and kernel space) is implemented using netlink sockets. 1) Netlink interface functions are added: ibnl_unicast() and ibnl_mulitcast() for sending netlink messages to user space 2) The signature of the existing ibnl_put_msg() is changed to be more generic 3) Two netlink clients are added: RDMA_NL_NES, RDMA_NL_C4IW corresponding to the two iWarp drivers - nes and cxgb4 which use the IWPM service 4) Enums are added to enumerate the attributes in the netlink messages, which are exchanged between the user space IWPM service and the iWARP drivers Signed-off-by: NTatyana Nikolova <tatyana.e.nikolova@intel.com> Signed-off-by: NSteve Wise <swise@opengridcomputing.com> Reviewed-by: NPJ Waskiewicz <pj.waskiewicz@solidfire.com> [ Fold in range checking fixes and nlh_next removal as suggested by Dan Carpenter and Steve Wise.

Pull UBIFS updates from Artem Bityutskiy: "This contains several UBIFS fixes. One of them fixes a race condition between the mmap page fault path and fsync. Another just removes a bogus assertion from the UBIFS memory shrinker.

Otherwise the kernel oopses when remounting with IPv6 server because net is dereferenced in dev_get_by_name. Use net ns of current thread so that dev_get_by_name does not operate on foreign ns. Changing the address is prohibited anyway so this should not affect anything.
