2013-02-05kgdb: remove #include <linux/serial_8250.h> from kgdb.hGreg Kroah-Hartman1-1/+0
There's no reason kgdb.h itself needs to include the 8250 serial port header file. So push it down to the _very_ limited number of individual drivers that need the values in that file, and fix up the places where people really wanted serial_core.h and platform_device.h.

2013-01-22ptrace: introduce signal_wake_up_state() and ptrace_signal_wake_up()Oleg Nesterov1-1/+10
Cleanup and preparation for the next change. signal_wake_up(resume => true) is overused. None of ptrace/jctl callers actually want to wakeup a TASK_WAKEKILL task, but they can't specify the necessary mask. Turn signal_wake_up() into signal_wake_up_state(state), reintroduce signal_wake_up() as a trivial helper, and add ptrace_signal_wake_up() which adds __TASK_TRACED. This way ptrace_signal_wake_up() can work "inside" ptrace_request() even if the tracee doesn't have the TASK_WAKEKILL bit set.

2013-01-19tty: Added a CONFIG_TTY option to allow removal of TTYJoe Millenbach3-11/+43
The option allows you to remove TTY and compile without errors. This saves space on systems that won't support TTY interfaces anyway. bloat-o-meter output is below. The bulk of this patch consists of Kconfig changes adding "depends on TTY" to various serial devices and similar drivers that require the TTY layer. Ideally, these dependencies would occur on a common intermediate symbol such as SERIO, but most drivers "select SERIO" rather than "depends on SERIO", and "select" does not respect dependencies. bloat-o-meter output comparing our previous minimal to new minimal by removing TTY.

2013-01-16module, async: async_synchronize_full() on module init iff async is usedTejun Heo1-0/+1
If the default iosched is built as module, the kernel may deadlock while trying to load the iosched module on device probe if the probing was running off async. This is because async_synchronize_full() at the end of module init ends up waiting for the async job which initiated the module loading. async A modprobe 1. finds a device 2. registers the block device 3. request_module(default iosched) 4. modprobe in userland 5. load and init module 6. async_synchronize_full() Async A waits for modprobe to finish in request_module() and modprobe waits for async A to finish in async_synchronize_full(). Because there's no easy to track dependency once control goes out to userland, implementing properly nested flushing is difficult. For now, make module init perform async_synchronize_full() iff module init has queued async jobs as suggested by Linus. This avoids the described deadlock because iosched module doesn't use async and thus wouldn't invoke async_synchronize_full(). This is hacky and incomplete. It will deadlock if async module loading nests; however, this works around the known problem case and seems to be the best of bad options.

2013-01-15cpuidle: remove the power_specified field in the driverDaniel Lezcano1-1/+1
We realized that the power usage field is never filled and when it is filled for tegra, the power_specified flag is not set causing all of these values to be reset when the driver is initialized with set_power_state(). However, the power_specified flag can be simply removed under the assumption that the states are always backward sorted, which is the case with the current code. This change allows the menu governor select function and the cpuidle_play_dead() to be simplified. Moreover, the set_power_states() function can removed as it does not make sense any more. Drop the power_specified flag from struct cpuidle_driver and make the related changes as described above. As a consequence, this also fixes the bug where on the dynamic C-states system, the power fields are not initialized.

2013-01-14[libata] replace sata_settings with devslp_timingShane Huang2-5/+7
NCQ capability was used to check availability of SATA Settings page from Identify Device Data Log, which contains DevSlp timing variables. It does not work on some HDDs and leads to error messages. IDENTIFY word 78 bit 5(Hardware Feature Control) can't work either because it is only the sufficient condition of Identify Device data log, not the necessary condition. This patch replaced ata_device->sata_settings with ->devslp_timing to only save DevSlp timing variables(8 bytes), instead of the whole SATA Settings page(512 bytes).

After alloc_netdev*() call, some cfg80211 drivers provide they own ethtool_ops, but some do not. For them, wireless core provide generic cfg80211_ethtool_ops, which is assigned in NETDEV_REGISTER notify call: if (!dev->ethtool_ops) dev->ethtool_ops = &cfg80211_ethtool_ops; But after Eric's commit, dev->ethtool_ops is no longer NULL (on cfg80211 drivers without custom ethtool_ops), but points to &default_ethtool_ops. In order to fix the problem, provide function which will overwrite default_ethtool_ops and use it by wireless core.

2013-01-12lib/rbtree.c: avoid the use of non-static __always_inlineMichel Lespinasse1-3/+11
lib/rbtree.c declared __rb_erase_color() as __always_inline void, and then exported it with EXPORT_SYMBOL. This was because __rb_erase_color() must be exported for augmented rbtree users, but it must also be inlined into rb_erase() so that the dummy callback can get optimized out of that call site. (Actually with a modern compiler, none of the dummy callback functions should even be generated as separate text functions). The above usage is legal C, but it was unusual enough for some compilers to warn about it. This change makes things more explicit, with a static __always_inline ____rb_erase_color function for use in rb_erase(), and a separate non-inline __rb_erase_color function for use in rb_erase_augmented call sites.

2013-01-12mm: compaction: partially revert capture of suitable high-order pageMel Gorman2-3/+2
Eric Wong reported on 3.7 and 3.8-rc2 that ppoll() got stuck when waiting for POLLIN on a local TCP socket. It was easier to trigger if there was disk IO and dirty pages at the same time and he bisected it to commit 1fb3f8ca0e92 ("mm: compaction: capture a suitable high-order page immediately when it is made available"). The intention of that patch was to improve high-order allocations under memory pressure after changes made to reclaim in 3.6 drastically hurt THP allocations but the approach was flawed. For Eric, the problem was that page->pfmemalloc was not being cleared for captured pages leading to a poor interaction with swap-over-NFS support causing the packets to be dropped. However, I identified a few more problems with the patch including the fact that it can increase contention on zone->lock in some cases which could result in async direct compaction being aborted early. In retrospect the capture patch took the wrong approach. What it should have done is mark the pageblock being migrated as MIGRATE_ISOLATE if it was allocating for THP and avoided races that way. While the patch was showing to improve allocation success rates at the time, the benefit is marginal given the relative complexity and it should be revisited from scratch in the context of the other reclaim-related changes that have taken place since the patch was first written and tested. This patch partially reverts commit 1fb3f8ca0e92 ("mm: compaction: capture a suitable high-order page immediately when it is made available").

2013-01-12linux/audit.h: move ptrace.h include to kernel headerMike Frysinger2-1/+1
While the kernel internals want pt_regs (and so it includes linux/ptrace.h), the user version of audit.h does not need it. So move the include out of the uapi version. This avoids issues where people want the audit defines and userland ptrace api. Including both the kernel ptrace and the userland ptrace headers can easily lead to failure.

2013-01-12audit: create explicit AUDIT_SECCOMP event typeKees Cook2-1/+3
The seccomp path was using AUDIT_ANOM_ABEND from when seccomp mode 1 could only kill a process. While we still want to make sure an audit record is forced on a kill, this should use a separate record type since seccomp mode 2 introduces other behaviors. In the case of "handled" behaviors (process wasn't killed), only emit a record if the process is under inspection. This change also fixes userspace examination of seccomp audit events, since it was considered malformed due to missing fields of the AUDIT_ANOM_ABEND event type.

2013-01-12lib: cpu_rmap: avoid flushing all workqueuesDavid Decotigny2-14/+4
In some cases, free_irq_cpu_rmap() is called while holding a lock (eg rtnl). This can lead to deadlocks, because it invokes flush_scheduled_work() which ends up waiting for whole system workqueue to flush, but some pending works might try to acquire the lock we are already holding. This commit uses reference-counting to replace irq_run_affinity_notifiers(). It also removes irq_run_affinity_notifiers() altogether.
