As described in e6fa16ab ("signal: sigprocmask() should do retarget_shared_pending()") the modification of current->blocked is incorrect as we need to check whether the signal we're about to block is pending in the shared queue. Also, use the new helper function introduced in commit 5e6292c0 ("signal: add block_sigmask() for adding sigmask to current->blocked") which centralises the code for updating current->blocked after successfully delivering a signal and reduces the amount of duplicate code across architectures. In the past some architectures got this code wrong, so using this helper function should stop that from happening again. Acked-by:

It is wrong to change ->blocked directly, see e6fa16ab. Change handle_signal() and sys_rt_sigreturn() to use the right helper, set_current_blocked(). Cc: Hans-Christian Egtvedt <egtvedt@samfundet.no> Acked-by:

The current handle_signal() implementation is broken - it will mask signals if we fail to setup the signal stack frame, which isn't the desired behaviour, we should only be masking signals if we succeed in setting up the stack frame. It looks like this code was copied from the old (broken) arm implementation but wasn't updated when the arm code was fixed in commit a6c61e9d ("[ARM] 3168/1: Update ARM signal delivery and masking").

There are a couple of problems with the current signal code, 1. If we failed to setup the signal stack frame then we should not be masking any signals. 2. ka->sa.sa_mask is only added to the current blocked signals list if SA_NODEFER is set in ka->sa.sa_flags. If we successfully setup the signal frame and are going to run the handler then we must honour sa_mask. Acked-by:
-
Matt Fleming authored
get_signal_to_deliver() already resets the signal handler if SA_ONESHOT is set in ka->sa.sa_flags, there's no need to do it again in handle_signal(). Furthermore, because we were modifying ka->sa.sa_handler (which is a copy of sighand->action[]) instead of sighand->action[] the original code actually had no effect on signal delivery. Acked-by:

Matt Fleming authored
Instead of open coding the sequence from force_sigsegv() just call it. This also fixes a bug because we were modifying ka->sa.sa_handler (which is a copy of sighand->action[]), whereas the intention of the code was to modify sighand->action[] directly. As the original code was working with a copy it had no effect on signal delivery. Acked-by:

Pull RCU changes from Ingo Molnar: "This is the v3.5 RCU tree from Paul E. McKenney: 1) A set of improvements and fixes to the RCU_FAST_NO_HZ feature (with more on the way for 3.6). Posted to LKML: https://lkml.org/lkml/2012/4/23/324 (commits 1-3 and 5), https://lkml.org/lkml/2012/4/16/611 (commit 4), https://lkml.org/lkml/2012/4/30/390 (commit 6), and https://lkml.org/lkml/2012/5/4/410 (commit 7, combined with the other commits for the convenience of the tester). 2) Changes to make rcu_barrier() avoid disrupting execution of CPUs that have no RCU callbacks. Posted to LKML: https://lkml.org/lkml/2012/4/23/322. 3) A couple of commits that improve the efficiency of the interaction between preemptible RCU and the scheduler, these two being all that survived an abortive attempt to allow preemptible RCU's __rcu_read_lock() to be inlined. The full set was posted to LKML at https://lkml.org/lkml/2012/4/14/143, and the first and third patches of that set remain. 4) Lai Jiangshan's algorithmic implementation of SRCU, which includes call_srcu() and srcu_barrier(). A major feature of this new implementation is that synchronize_srcu() no longer disturbs the execution of other CPUs. This work is based on earlier implementations by Peter Zijlstra and Paul E. McKenney. Posted to LKML: https://lkml.org/lkml/2012/2/22/82. 5) A number of miscellaneous bug fixes and improvements which were posted to LKML at: https://lkml.org/lkml/2012/4/23/353 with subsequent updates posted to LKML." * 'core-rcu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (32 commits) rcu: Make rcu_barrier() less disruptive rcu: Explicitly initialize RCU_FAST_NO_HZ per-CPU variables rcu: Make RCU_FAST_NO_HZ handle timer migration rcu: Update RCU maintainership rcu: Make exit_rcu() more precise and consolidate rcu: Move PREEMPT_RCU preemption to switch_to() invocation rcu: Ensure that RCU_FAST_NO_HZ timers expire on correct CPU rcu: Add rcutorture test for call_srcu() rcu: Implement per-domain single-threaded call_srcu() state machine rcu: Use single value to handle expedited SRCU grace periods rcu: Improve srcu_readers_active_idx()'s cache locality rcu: Remove unused srcu_barrier() rcu: Implement a variant of Peter's SRCU algorithm rcu: Improve SRCU's wait_idx() comments rcu: Flip ->completed only once per SRCU grace period rcu: Increment upper bit only for srcu_read_lock() rcu: Remove fast check path from __synchronize_srcu() rcu: Direct algorithmic SRCU implementation rcu: Introduce rcutorture testing for rcu_barrier() timer: Fix mod_timer_pinned() header comment ... -

Also a move of all the ColdFire subarch support files into the existing coldfire directory. The sub-directories just ended up duplicating Makefiles and now only contain really simple pieces of code.

This reverts commit 8c01a529. It turns out the d_unhashed() check isn't unnecessary after all: while it's true that unhashing will increment the sequence numbers, that does not necessarily invalidate the RCU lookup, because it might have seen the dentry pointer (before it got unhashed), but by the time it loaded the sequence number, it could have seen the *new* sequence number (after it got unhashed). End result: we might look up an unhashed dentry that is about to be freed, with the sequence number never indicating anything bad about it. So checking that the dentry is still hashed (*after* reading the sequence number) is indeed the proper fix, and was never unnecessary. Reported-by:

Pull usb-gadget scsi-target merge from Nicholas Bellinger: "As promised, here is the pull request for Sebastian's usb-gadget target UASP / BOT driver for v3.5-rc1. This code has been in linux-next for a number of weeks, and is now ready for an initial merge. This fabric uses the target framework to provide a usb gadget device. This gadget supports the USB Attached SCSI Protocol (UASP) and Bulk Only Transfers (BOT or BBB). BOT is the primary interface, UAS is the alternative interface. Note this series is dependent upon a single target core patch for adding se_cmd->unknown_data_length in target-pending/for-next, that got merged in the parent. Kudos to Sebastian for making this driver happen so easily, and for his patches to improve usb-core and target core along the way to his goal. Also thanks to Felipe + Greg-KH for their help in getting this driver ready for mainline." * 'usb-target-merge' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: usb-gadget: Initial merge of target module for UASP + BOT

Pull scsi-target changes from Nicholas Bellinger: "There has been lots of work in existing code in a number of areas this past cycle. The major highlights have been: * Removal of transport_do_task_sg_chain() from core + fabrics (Roland) * target-core: Removal of se_task abstraction from target-core and enforce hw_max_sectors for pSCSI backends (hch) * Re-factoring of iscsi-target tx immediate/response queues (agrover) * Conversion of iscsi-target back to using target core memory allocation logic (agrover) We've had one last minute iscsi-target patch go into for-next to address a nasty regression bug related to the target core allocation logic conversion from agrover that is not included in friday's linux-next build, but has been included in this series. On the new fabric module code front for-3.5, here is a brief status update for the three currently in flight this round: * usb-gadget target driver: Sebastian Siewior's driver for supporting usb-gadget target mode operation. This will be going out as a separate PULL request from target-pending/usb-target-merge with subsystem maintainer ACKs. There is one minor target-core patch in this series required to function. * sbp ieee-1394/firewire target driver: Chris Boot's driver for supportting the Serial Block Protocol (SBP) across IEEE-1394 Firewire hardware.

Pull regulator updates from Mark Brown: "The major thing here is the addition of some helpers to factor code out of drivers, making a fair proportion of regulators much more just data rather than code which is nice. - Helpers in the core for regulators using regmap, providing generic implementations of the enable and voltage selection operations which just need data to describe them in the drivers. - Split out voltage mapping and voltage setting, allowing many more drivers to take advantage of the infrastructure for selectors. - Loads and loads of cleanups from Axel Lin once again, including many changes to take advantage of the above new framework features - New drivers for Ricoh RC5T583, TI TPS62362, TI TPS62363, TI TPS65913, TI TWL6035 and TI TWL6037. Some of the registration changes to support the core refactoring caused so many conflicts that eventually topic branches were abandoned for this release." * tag 'regulator-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator: (227 commits) regulator: tps65910: use of_node of matched regulator being register regulator: tps65910: dt: support when "regulators" node found regulator: tps65910: add error message in case of failure regulator: tps62360: dt: initialize of_node param for regulator register. regulator: tps65910: use devm_* for memory allocation regulator: tps65910: use small letter for regulator names mfd: tpx6586x: Depend on regulator regulator: regulator for Palmas Kconfig regulator: regulator driver for Palmas series chips regulator: Enable Device Tree for the db8500-prcmu regulator driver regulator: db8500-prcmu: Separate regulator registration from probe regulator: ab3100: Use regulator_map_voltage_iterate() regulator: tps65217: Convert to set_voltage_sel and map_voltage regulator: Enable the ab8500 for Device Tree regulator: ab8500: Split up probe() into manageable pieces regulator: max8925: Remove check_range function and max_uV from struct rc5t583_regulator_info regulator: max8649: Remove unused check_range() function regulator: rc5t583: Remove max_uV from struct rc5t583_regulator_info regulator: da9052: Convert to set_voltage_sel and map_voltage regulator: max8952: Use devm_kzalloc ... -

Pull regmap updates from Mark Brown: "A surprisingly large series of updates for regmap this time, mostly due to all the work Stephen Warren has done to add support for MMIO buses. This wasn't really the target for the framework but it turns out that there's a reasonable number of cases where it's very helpful to use the register cache support to allow the register map to remain available while the device is suspended. - A MMIO bus implementation, contributed by Stephen Warren. Currently this is limited to 32 bit systems and native endian registers. - Support for naming register maps, mainly intended for MMIO devices with multiple register banks. This was also contributed by Stephen Warren. - Support for register striding, again contributed by Stephen Warren and mainly intended for use with MMIO as typically the registers will be a fixed size but byte addressed. - irqdomain support for the generic regmap irq_chip, including support for dynamically allocate interrupt numbers. - A function dev_get_regmap() which allows frameworks using regmap to obtain the regmap for a device from the struct device, making life a little simpler for them. - Updates to regmap-irq to support more chips (contributed by Graeme Gregory) and to use irqdomains. - Support for devices with 24 bit register addresses. The striding support collided with all the topic branches so the branches look a bit messy and eventually I just gave up. There's also the TI Palmas driver and a couple of other isolated MFD patches that all depend on new regmap features so are being merged here." * tag 'regmap-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap: (24 commits) mfd: palmas PMIC device support Kconfig mfd: palmas PMIC device support regmap: Fix typo in IRQ register striding mfd: wm8994: Update to fully use irq_domain regmap: add support for non contiguous status to regmap-irq regmap: Convert regmap_irq to use irq_domain regmap: Pass back the allocated regmap IRQ controller data mfd: da9052: Fix genirq abuse regmap: Implement dev_get_regmap() regmap: Devices using format_write don't support bulk operations regmap: Converts group operation into single read write operations regmap: Cache single values read from the chip regmap: fix compile errors in regmap-irq.c due to stride changes regmap: implement register striding regmap: fix compilation when !CONFIG_DEBUG_FS regmap: allow regmap instances to be named regmap: validate regmap_raw_read/write val_len regmap: mmio: remove some error checks now in the core regmap: mmio: convert some error returns to BUG() regmap: add MMIO bus support ... -
