2014-03-10ASoC: Add a per component dai listLars-Peter Clausen
Now that every DAI has a component we can track the DAIs on a per component basis. This simplifies the DAI lookup when we are only interested in DAIs of a specific component and also makes it possible to have multiple components with the same parent device and also register DAIs.

For quite a long time now, workqueue only treats two work items identical iff both their addresses and callbacks match. This is to avoid introducing false dependency through the work item being recycled while being executed. This changes non-reentrancy guarantee for the users of PREPARE[_DELAYED]_WORK() - if the function changes, reentrancy isn't guaranteed against the previous instance. Firewire depended on such nonreentrancy guarantee.

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing fix from Steven Rostedt: "In the past, I've had lots of reports about trace events not working. Developers would say they put a trace_printk() before and after the trace event but when they enable it (and the trace event said it was enabled) they would see the trace_printks but not the trace event. I was not able to reproduce this, but that's because I wasn't looking at the right location. Recently, another bug came up that showed the issue. If your kernel supports signed modules but allows for non-signed modules to be loaded, then when one is, the kernel will silently set the MODULE_FORCED taint on the module. Although, this taint happens without the need for insmod --force or anything of the kind, it labels the module with that taint anyway. If this tainted module has tracepoints, the tracepoints will be ignored because of the MODULE_FORCED taint. But no error message will be displayed. Worse yet, the event infrastructure will still be created letting users enable the trace event represented by the tracepoint, although that event will never actually be enabled. This is because the tracepoint infrastructure allows for non-existing tracepoints to be enabled for new modules to arrive and have their tracepoints set. Although there are several things wrong with the above, this change only addresses the creation of the trace event files for tracepoints that are not created when a module is loaded and is tainted. This change will print an error message about the module being tainted and not the trace events will not be created, and it does not create the trace event infrastructure" * tag 'trace-fixes-v3.14-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Do not add event files for modules that fail tracepoints

2014-03-07firewire: don't use PREPARE_DELAYED_WORKTejun Heo
PREPARE_[DELAYED_]WORK() are being phased out. They have few users and a nasty surprise in terms of reentrancy guarantee as workqueue considers work items to be different if they don't have the same work function. firewire core-device and sbp2 have been been multiplexing work items with multiple work functions. Introduce fw_device_workfn() and sbp2_lu_workfn() which invoke fw_device->workfn and sbp2_logical_unit->workfn respectively and always use the two functions as the work functions and update the users to set the ->workfn fields instead of overriding work functions using PREPARE_DELAYED_WORK(). This fixes a variety of possible regressions since a2c1c57be8d9 "workqueue: consider work function when searching for busy work items" due to which fw_workqueue lost its required non-reentrancy property.

2014-03-06regmap: add regmap_parse_val apiNenghua Cao
In some cases, we need regmap's format parse_val function to do be/le translation according to the bus configuration. For example, snd_soc_bytes_put() uses regmap to write/read values, and use cpu_to_be() directly to covert MASK into big endian. This is a defect, and should use regmap's format function to do it according to bus configuration. Signed-off-by: Nenghua Cao <nhcao@marvell.com> Signed-off-by: Mark Brown <broonie@linaro.org>

2014-03-04iscsi/iser-target: Fix isert_conn->state hung shutdown issuesNicholas Bellinger
This patch addresses a couple of different hug shutdown issues related to wait_event() + isert_conn->state. First, it changes isert_conn->conn_wait + isert_conn->conn_wait_comp_err from waitqueues to completions, and sets ISER_CONN_TERMINATING from within isert_disconnect_work(). Second, it splits isert_free_conn() into isert_wait_conn() that is called earlier in iscsit_close_connection() to ensure that all outstanding commands have completed before continuing. Finally, it breaks isert_cq_comp_err() into seperate TX / RX related code, and adds logic in isert_cq_rx_comp_err() to wait for outstanding commands to complete before setting ISER_CONN_DOWN and calling complete(&isert_conn->conn_wait_comp_err).

2014-03-04mm: numa: bugfix for LAST_CPUPID_NOT_IN_PAGE_FLAGSLiu Ping Fan
When doing some numa tests on powerpc, I triggered an oops bug. I find it is caused by using page->_last_cpupid. It should be initialized as "-1 & LAST_CPUPID_MASK", but not "-1".

This can be reproduced with default config since 3.11 kernels. A reproducer can be found in the kernel's selftest directory for networking by running ./psock_tpacket. The problem is that an order=2 compound page (allocated by alloc_one_pg_vec_page() is part of the munlocked VM_MIXEDMAP vma (mapped by packet_mmap()) and mistaken for a THP page and assumed to be order=9. The checks for THP in munlock came with commit ff6a6da60b89 ("mm: accelerate munlock() treatment of THP pages"), i.e. since 3.9, but did not trigger a bug. It just makes munlock_vma_pages_range() skip such compound pages until the next 512-pages-aligned page, when it encounters a head page. This is however not a problem for vma's where mlocking has no effect anyway, but it can distort the accounting. Since commit 7225522bb429 ("mm: munlock: batch non-THP page isolation and munlock+putback using pagevec") this can trigger a VM_BUG_ON in PageTransHuge() check. This patch fixes the issue by adding VM_MIXEDMAP flag to VM_SPECIAL, a list of flags that make vma's non-mlockable and non-mergeable. The reasoning is that VM_MIXEDMAP vma's are similar to VM_PFNMAP, which is already on the VM_SPECIAL list, and both are intended for non-LRU pages where mlocking makes no sense anyway.

2014-03-04mm: close PageTail raceDavid Rientjes
Commit bf6bddf1924e ("mm: introduce compaction and migration for ballooned pages") introduces page_count(page) into memory compaction which dereferences page->first_page if PageTail(page). This results in a very rare NULL pointer dereference on the aforementioned page_count(page). Indeed, anything that does compound_head(), including page_count() is susceptible to racing with prep_compound_page() and seeing a NULL or dangling page->first_page pointer. This patch uses Andrea's implementation of compound_trans_head() that deals with such a race and makes it the default compound_head() implementation. This includes a read memory barrier that ensures that if PageTail(head) is true that we return a head page that is neither NULL nor dangling. The patch then adds a store memory barrier to prep_compound_page() to ensure page->first_page is set. This is the safest way to ensure we see the head page that we are expecting, PageTail(page) is already in the unlikely() path and the memory barriers are unfortunately required. Hugetlbfs is the exception, we don't enforce a store memory barrier during init since no race is possible.

2014-03-03tracing: Do not add event files for modules that fail tracepointsSteven Rostedt (Red Hat)
If a module fails to add its tracepoints due to module tainting, do not create the module event infrastructure in the debugfs directory. As the events will not work and worse yet, they will silently fail, making the user wonder why the events they enable do not display anything. Having a warning on module load and the events not visible to the users will make the cause of the problem much clearer.

2014-02-25ipc,mqueue: remove limits for the amount of system-wide queuesDavidlohr Bueso
Commit 93e6f119c0ce ("ipc/mqueue: cleanup definition names and locations") added global hardcoded limits to the amount of message queues that can be created. While these limits are per-namespace, reality is that it ends up breaking userspace applications. Historically users have, at least in theory, been able to create up to INT_MAX queues, and limiting it to just 1024 is way too low and dramatic for some workloads and use cases. For instance, Madars reports: "This update imposes bad limits on our multi-process application. As our app uses approaches that each process opens its own set of queues (usually something about 3-5 queues per process). In some scenarios we might run up to 3000 processes or more (which of-course for linux is not a problem). Thus we might need up to 9000 queues or more. All processes run under one user." Other affected users can be found in launchpad bug #1155695: https://bugs.launchpad.net/ubuntu/+source/manpages/+bug/1155695 Instead of increasing this limit, revert it entirely and fallback to the original way of dealing queue limits -- where once a user's resource limit is reached, and all memory is used, new queues cannot be created.

This reverts commit c4a391b53a72d2df4ee97f96f78c1d5971b47489. Dave Chinner <david@fromorbit.com> has reported the commit may cause some inodes to be left out from sync(2). This is because we can call redirty_tail() for some inode (which sets i_dirtied_when to current time) after sync(2) has started or similarly requeue_inode() can set i_dirtied_when to current time if writeback had to skip some pages. The real problem is in the functions clobbering i_dirtied_when but fixing that isn't trivial so revert is a safer choice for now.
