2010-08-20oom: __task_cred() need rcu_read_lock()KOSAKI Motohiro
dump_tasks() needs to hold the RCU read lock around its access of the target task's UID. To this end it should use task_uid() as it only needs that one thing from the creds. The fact that dump_tasks() holds tasklist_lock is insufficient to prevent the target process replacing its credentials on another CPU. Then, this patch change to call rcu_read_lock() explicitly. =================================================== [ INFO: suspicious rcu_dereference_check() usage. ] --------------------------------------------------- mm/oom_kill.c:410 invoked rcu_dereference_check() without protection! other info that might help us debug this: rcu_scheduler_active = 1, debug_locks = 1 4 locks held by kworker/1:2/651: #0: (events){+.+.+.}, at: [<ffffffff8106aae7>] process_one_work+0x137/0x4a0 #1: (moom_work){+.+...}, at: [<ffffffff8106aae7>] process_one_work+0x137/0x4a0 #2: (tasklist_lock){.+.+..}, at: [<ffffffff810fafd4>] out_of_memory+0x164/0x3f0 #3: (&(&p->alloc_lock)->rlock){+.+...}, at: [<ffffffff810fa48e>] find_lock_task_mm+0x2e/0x70 Signed-off-by: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com> Signed-off-by: David Howells <dhowells@redhat.com> Acked-by: Paul E.

2010-08-20x86, tsc, sched: Recompute cyc2ns_offset's during resume from sleep statesSuresh Siddha
TSC's get reset after suspend/resume (even on cpu's with invariant TSC which runs at a constant rate across ACPI P-, C- and T-states). And in some systems BIOS seem to reinit TSC to arbitrary large value (still sync'd across cpu's) during resume. This leads to a scenario of scheduler rq->clock (sched_clock_cpu()) less than rq->age_stamp (introduced in 2.6.32). This leads to a big value returned by scale_rt_power() and the resulting big group power set by the update_group_power() is causing improper load balancing between busy and idle cpu's after suspend/resume. This resulted in multi-threaded workloads (like kernel-compilation) go slower after suspend/resume cycle on core i5 laptops. Fix this by recomputing cyc2ns_offset's during resume, so that sched_clock() continues from the point where it was left off during suspend.

We leave the vruntime in relative state, so the time delay until wake_up_new_task() doesn't matter. wake_up_new_task() -- Since task_fork_fair() left p->vruntime in relative state we can safely migrate, the activate_task() on the remote rq will call update_rq_clock() and causes the clock to be synced (enough).

2010-08-20ALSA: hda - Fix stream and channel-ids codec-bus wideTakashi Iwai
The new sticky PCM parameter introduced the delayed clean-ups of stream- and channel-id tags. In the current implementation, this check (adding dirty flag) and actual clean-ups are done only for the codec chip. However, with HD-audio architecture, multiple codecs can be on a single bus, and the controller assign stream- and channel-ids in the bus-wide. In this patch, the stream-id and channel-id are checked over all codecs connected to the corresponding bus. Together with it, the mutex is moved to struct hda_bus, as this becomes also bus-wide.

2010-08-20drm/radeon: Fix stack data leakJean Delvare
Always zero-init a structure on the stack which is returned by a function. Otherwise you may leak random stack data from previous function calls. This fixes the following warning I was seeing: CC [M] drivers/gpu/drm/radeon/radeon_atombios.o drivers/gpu/drm/radeon/radeon_atombios.c: In function "radeon_atom_get_hpd_info_from_gpio": drivers/gpu/drm/radeon/radeon_atombios.c:261: warning: "hpd.plugged_state" is used uninitialized in this function Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: David Airlie <airlied@linux.ie> Cc: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-08-20drm/radeon/kms: fix GTT/VRAM overlapping testJerome Glisse
GTT/VRAM overlapping test had a typo which leaded to not detecting case when vram_end > gtt_end. This patch fix the logic and should fix #16574 Signed-off-by: Jerome Glisse <jglisse@redhat.com> Cc: stable@kernel.org Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-08-19x86, hotplug: Serialize CPU hotplug to avoid bringup concurrency issuesBorislav Petkov
When testing cpu hotplug code on 32-bit we kept hitting the "CPU%d: Stuck ??" message due to multiple cores concurrently accessing the cpu_callin_mask, among others. Since these codepaths are not protected from concurrent access due to the fact that there's no sane reason for making an already complex code unnecessarily more complex - we hit the issue only when insanely switching cores off- and online - serialize hotplugging cores on the sysfs level and be done with it.

If the code were already aligned to 64 bytes, wr instruction would be executed twice --- once in delay slot and once in the jump target. Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-08-19firewire: core: do not use del_timer_sync() in interrupt contextClemens Ladisch
Because we might be in interrupt context, replace del_timer_sync() with del_timer(). If the timer is already running, we know that it will clean up the transaction, so we do not need to do any further processing in the normal transaction handler. Many thanks to Yong Zhang for diagnosing this.
