2014-06-18cpu: add generic support for CPU feature based module autoloadingArd Biesheuvel
This patch adds support for advertising optional CPU features over udev using the modalias, and for declaring compatibility with/dependency upon such a feature in a module. The mapping between feature numbers and actual features should be provided by the architecture in a file called <asm/cpufeature.h> which exports the following functions/macros: - cpu_feature(FEAT), a preprocessor macro that maps token FEAT to a numeric index; - bool cpu_have_feature(n), returning whether this CPU has support for feature #n; - MAX_CPU_FEATURES, an upper bound for 'n' in the previous function. The feature can then be enabled by setting CONFIG_GENERIC_CPU_AUTOPROBE for the architecture. For instance, a module that registers its module init function using module_cpu_feature_match(FEAT_X, module_init_function) will be probed automatically when the CPU's support for the 'FEAT_X' feature is advertised over udev, and will only allow the module to be loaded by hand if the 'FEAT_X' feature is supported.

2014-06-18mailbox: Remove const from client argument of mbox_request_channel()Mark Brown
The struct mbox_client supplied to mbox_request_channel() is const but it is stored in the channel in a non-constant member causing compiler warnings. While the mailbox API should treat the struct mailbox_client as const itself the struct is passed back to the channel in callbacks without a const so we need to either remove the const, change the callbacks to take const or cast the const away when doing callbacks. Take the simplest option and just remove the const. Signed-off-by: Mark Brown <broonie@linaro.org>

2014-06-18Mailbox: Generic: Specify mailbox api bindingsJassi Brar
Due to the platform specific nature of remote's firmware, we can't do much to facilitate shareable client drivers. So the Mailbox api is more like a bunch of useful functions put together.

2014-06-18drm/i915: dp: fix order of dp aux i2c device cleanupImre Deak
commit 80f65de3c9b8101c1613fa82df500ba6a099a11c upstream. Atm we set the parent of the dp i2c device to be the correspondig connector device. During driver cleanup we first remove the connector device through intel_modeset_cleanup()->drm_sysfs_connector_remove() and only after that the i2c device through the encoder's destroy callback. This order is not supported by the device core and we'll get a warning, see the below bugzilla ticket. The proper order is to remove first any child device and only then the parent device. The first part of the fix changes the i2c device's parent to be the drm device. Its logical owner is not the connector anyway, but the encoder. Since the encoder doesn't have a device object, the next best choice is the drm device. This is the same what we do in the case of the sdvo i2c device and what the nouveau driver does. The second part creates a symlink in the connector's sysfs directory pointing to the i2c device. This is so, that we keep the current ABI, which also makes sense in case someone wants to look up the i2c device belonging to a specific connector.

2014-06-18drm/i915: add unregister callback to connectorImre Deak
commit 4932e2c3c716067f3580e1a9687bed9d751549e3 upstream. Since commit d9255d57147e1dbcebdf6670409c2fa0ac3609e6 Author: Paulo Zanoni <paulo.r.zanoni@intel.com> Date:   Thu Sep 26 20:05:59 2013 -0300 it became clear that we need to separate the unload sequence into two parts: 1. remove all interfaces through which new operations on some object (crtc, encoder, connector) can be started and make sure all pending operations are completed 2. do the actual tear down of the internal representation of the above objects The above commit achieved this separation for connectors by splitting out the sysfs removal part from the connector's destroy callback and doing this removal before calling drm_mode_config_cleanup() which does the actual tear-down of all the drm objects. Since we'll have to customize the interface removal part for different types of connectors in the upcoming patches, add a new unregister callback and move the interface removal part to it. No functional change.

2014-06-18iscsi-target: Fix wrong buffer / buffer overrun in iscsi_change_param_value()Roland Dreier
commit 79d59d08082dd0a0a18f8ceb78c99f9f321d72aa upstream. In non-leading connection login, iscsi_login_non_zero_tsih_s1() calls iscsi_change_param_value() with the buffer it uses to hold the login PDU, not a temporary buffer. This leads to the login header getting corrupted and login failing for non-leading connections in MC/S. Fix this by adding a wrapper iscsi_change_param_sprintf() that handles the temporary buffer itself to avoid confusion. Also handle sending a reject in case of failure in the wrapper, which lets the calling code get quite a bit smaller and easier to read. Finally, bump the size of the temporary buffer from 32 to 64 bytes to be safe, since "MaxRecvDataSegmentLength=" by itself is 25 bytes; with a trailing NUL, a value >= 1M will lead to a buffer overrun.

2014-06-18iser-target: Add missing target_put_sess_cmd for ImmedateData failureNicholas Bellinger
commit 6cc44a6fb46e1ecc1c28125aa8fa34d317aa9ea7 upstream. This patch addresses a bug where an early exception for SCSI WRITE with ImmediateData=Yes was missing the target_put_sess_cmd() call to drop the extra se_cmd->cmd_kref reference obtained during the normal iscsit_setup_scsi_cmd() codepath execution. This bug was manifesting itself during session shutdown within isert_cq_rx_comp_err() where target_wait_for_sess_cmds() would end up waiting indefinately for the last se_cmd->cmd_kref put to occur for the failed SCSI WRITE + ImmediateData descriptors. This fix follows what traditional iscsi-target code already does for the same failure case within iscsit_get_immediate_data().

2014-06-18mm: add !pte_present() check on existing hugetlb_entry callbacksNaoya Horiguchi
commit d4c54919ed86302094c0ca7d48a8cbd4ee753e92 upstream. The age table walker doesn't check non-present hugetlb entry in common path, so hugetlb_entry() callbacks must check it. The reason for this behavior is that some callers want to handle it in its own way. [ I think that reason is bogus, btw - it should just do what the regular code does, which is to call the "pte_hole()" function for such hugetlb entries - Linus] However, some callers don't check it now, which causes unpredictable result, for example when we have a race between migrating hugepage and reading /proc/pid/numa_maps. This patch fixes it by adding !pte_present checks on buggy callbacks. This bug exists for years and got visible by introducing hugepage migration.

2014-06-18intel_pstate: add sample time scalingDirk Brandewie
commit c4ee841f602e5eef8eab673295c49c5b49d7732b upstream. The PID assumes that samples are of equal time, which for a deferable timers this is not true when the system goes idle. This causes the PID to take a long time to converge to the min P state and depending on the pattern of the idle load can make the P state appear stuck. The hold-off value of three sample times before using the scaling is to give a grace period for applications that have high performance requirements and spend a lot of time idle, The poster child for this behavior is the ffmpeg benchmark in the Phoronix test suite.

2014-06-18percpu-refcount: fix usage of this_cpu_opsSebastian Ott
commit 0c36b390a546055b6815d4b93a2c9fed4d980ffb upstream. The percpu-refcount infrastructure uses the underscore variants of this_cpu_ops in order to modify percpu reference counters. (e.g. __this_cpu_inc()). However the underscore variants do not atomically update the percpu variable, instead they may be implemented using read-modify-write semantics (more than one instruction). Therefore it is only safe to use the underscore variant if the context is always the same (process, softirq, or hardirq). Otherwise it is possible to lose updates. This problem is something that Sebastian has seen within the aio subsystem which uses percpu refcounters both in process and softirq context leading to reference counts that never dropped to zeroes; even though the number of "get" and "put" calls matched. Fix this by using the non-underscore this_cpu_ops variant which provides correct per cpu atomic semantics and fixes the corrupted reference counts.

2014-06-18USB: Avoid runtime suspend loops for HCDs that can't handle suspend/resumeAlan Stern
commit 8ef42ddd9a53b73e6fc3934278710c27f80f324f upstream. Not all host controller drivers have bus-suspend and bus-resume methods. When one doesn't, it will cause problems if runtime PM is enabled in the kernel. The PM core will attempt to suspend the controller's root hub, the suspend will fail because there is no bus-suspend routine, and a -EBUSY error code will be returned to the PM core. This will cause the suspend attempt to be repeated shortly thereafter, in a never-ending loop. Part of the problem is that the original error code -ENOENT gets changed to -EBUSY in usb_runtime_suspend(), on the grounds that the PM core will interpret -ENOENT as meaning that the root hub has gotten into a runtime-PM error state. While this change is appropriate for real USB devices, it's not such a good idea for a root hub. In fact, considering the root hub to be in a runtime-PM error state would not be far from the truth. Therefore this patch updates usb_runtime_suspend() so that it adjusts error codes only for non-root-hub devices. Furthermore, the patch attempts to prevent the problem from occurring in the first place by not enabling runtime PM by default for root hubs whose host controller driver doesn't have bus_suspend and bus_resume methods.

commit c03890ff5e24a4bf59059f2d179f427559b7330a upstream. A recent patch that purported to fix firmware download on big-endian machines failed to add the corresponding sparse annotation to the i2c-header. This was reported by the kbuild test robot. Adding the appropriate annotation revealed another endianess bug related to the i2c-header Size-field in a code path that is exercised when the firmware is actually being downloaded (and not just verified and left untouched unless older than the firmware at hand). This patch adds the required sparse annotation to the i2c-header and makes sure that the Size-field is sent in little-endian byte order during firmware download also on big-endian machines. Note that this patch is only compile-tested, but that there is no functional change for little-endian systems.

commit 192a98e280e560510a62aca8cfa83b4ae7c095bb upstream. The conversion to a fixup table for Replacer model with ALC260 in commit 20f7d928 took the wrong widget NID for COEF setups. Namely, NID 0x1a should have been used instead of NID 0x20, which is the common node for all Realtek codecs but ALC260.

2014-06-18Staging: speakup: Update __speakup_paste_selection() tty (ab)usage to match vtBen Hutchings
commit 28a821c306889b9f2c3fff49abedc9b2c743eb73 upstream. This function is largely a duplicate of paste_selection() in drivers/tty/vt/selection.c, but with its own selection state. The speakup selection mechanism should really be merged with vt. For now, apply the changes from 'TTY: vt, fix paste_selection ldisc handling', 'tty: Make ldisc input flow control concurrency-friendly', and 'tty: Fix unsafe vt paste_selection()'.
