2008-03-15[PARISC] futex: special case cmpxchg NULL in kernel spaceKyle McMartin
Commit a0c1e9073ef7428a14309cba010633a6cd6719ea added code to futex.c to detect whether futex_atomic_cmpxchg_inatomic was implemented at run time: + curval = cmpxchg_futex_value_locked(NULL, 0, 0); + if (curval == -EFAULT) + futex_cmpxchg_enabled = 1; This is bogus on parisc, since page zero in kernel virtual space is the gateway page for syscall entry, and should not be read from the kernel.

2008-03-15[PARISC] pdc_console: fix bizarre panic on bootKyle McMartin
Commit 721fdf34167580ff98263c74cead8871d76936e6 introduced a subtle bug by accidently removing the "static" from iodc_dbuf. This resulted in, what appeared to be, a trap without *current set to a task. Probably the result of a trap in real mode while calling firmware. Also do other misc clean ups. Since the only input from firmware is non blocking, share iodc_dbuf between input and output, and spinlock the only callers. Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>

2008-03-15ACPI: Remove ACPI_CUSTOM_DSDT_INITRD optionLinus Torvalds
This essentially reverts commit 71fc47a9adf8ee89e5c96a47222915c5485ac437 ("ACPI: basic initramfs DSDT override support"), because the code simply isn't ready. It did ugly things to the init sequence to populate the rootfs image early, but that just ended up showing other problems with the whole approach. The fact is, the VFS layer simply isn't initialized this early, and the relevant ACPI code should either run much later, or this shouldn't be done at all. For 2.6.25, we'll just pick the latter option. We can revisit this concept later if necessary.

2008-03-15sched: fix overload performance: buddy wakeupsPeter Zijlstra
Currently we schedule to the leftmost task in the runqueue. When the runtimes are very short because of some server/client ping-pong, especially in over-saturated workloads, this will cycle through all tasks trashing the cache. Reduce cache trashing by keeping dependent tasks together by running newly woken tasks first. However, by not running the leftmost task first we could starve tasks because the wakee can gain unlimited runtime. Therefore we only run the wakee if its within a small (wakeup_granularity) window of the leftmost task. This preserves fairness, but does alternate server/client task groups.

2008-03-15sched: min_vruntime fixPeter Zijlstra
Current min_vruntime tracking is incorrect and will cause serious problems when we don't run the leftmost task for some reason. min_vruntime does two things; 1) it's used to determine a forward direction when the u64 vruntime wraps, 2) it's used to track the leftmost vruntime to position newly enqueued tasks from. The current logic advances min_vruntime whenever the current task's vruntime advance. Because the current task may pass the leftmost task still waiting we're failing the second goal. This causes new tasks to be placed too far ahead and thus penalizes their runtime. Fix this by making min_vruntime the min_vruntime of the waiting tasks by tracking it in enqueue/dequeue, and compare against current's vruntime to obtain the absolute minimum when placing new tasks.

2008-03-15sched: fix race in schedule()Hiroshi Shimamoto
Fix a hard to trigger crash seen in the -rt kernel that also affects the vanilla scheduler. There is a race condition between schedule() and some dequeue/enqueue functions; rt_mutex_setprio(), __setscheduler() and sched_move_task(). When scheduling to idle, idle_balance() is called to pull tasks from other busy processor. It might drop the rq lock. It means that those 3 functions encounter on_rq=0 and running=1. The current task should be put when running. Here is a possible scenario: CPU0 CPU1 | schedule() | ->deactivate_task() | ->idle_balance() | -->load_balance_newidle() rt_mutex_setprio() | | --->double_lock_balance() *get lock *rel lock * on_rq=0, ruuning=1 | * sched_class is changed | *rel lock *get lock : | : ->put_prev_task_rt() ->pick_next_task_fair() => panic The current process of CPU1(P1) is scheduling. Deactivated P1, and the scheduler looks for another process on other CPU's runqueue because CPU1 will be idle. idle_balance(), load_balance_newidle() and double_lock_balance() are called and double_lock_balance() could drop the rq lock. On the other hand, CPU0 is trying to boost the priority of P1. The result of boosting only P1's prio and sched_class are changed to RT. The sched entities of P1 and P1's group are never put. It makes cfs_rq invalid, because the cfs_rq has curr and no leaf, but pick_next_task_fair() is called, then the kernel panics.

2008-03-14nfsd: fix oops on access from high-numbered portsJ. Bruce Fields
This bug was always here, but before my commit 6fa02839bf9412e18e77 ("recheck for secure ports in fh_verify"), it could only be triggered by failure of a kmalloc(). After that commit it could be triggered by a client making a request from a non-reserved port for access to an export marked "secure". (Exports are "secure" by default.) The result is a struct svc_export with a reference count one too low, resulting in likely oopses next time the export is accessed. The reference counting here is not straightforward; a later patch will clean up fh_verify(). Thanks to Lukas Hejtmanek for the bug report and followup. Signed-off-by: J.

2008-03-14firewire: fw-ohci: use dma_alloc_coherent for ar_bufferJarod Wilson
Currently, we do nothing to guarantee we have a consistent DMA buffer for asynchronous receive packets. Rather than doing several sync's following a dma_map_single() to get consistent buffers, just switch to using dma_alloc_coherent(). Resolves constant buffer failures on my own x86_64 laptop w/4GB of RAM and likely to fix a number of other failures witnessed on x86_64 systems with 4GB of RAM or more.

2008-03-14firewire: fw-sbp2: set single-phase retry_limitJarod Wilson
Per the SBP-2 specification, all SBP-2 target devices must have a BUSY_TIMEOUT register. Per the 1394-1995 specification, the retry_limt portion of the register should be set to 0x0 initially, and set on the target by a logged in initiator (i.e., a Linux host w/firewire controller(s)). Well, as it turns out, lots of devices these days have actually moved on to starting to implement SBP-3 compliance, which says that retry_limit should default to 0xf instead (yes, SBP-3 stomps directly on 1394-1995, oops). Prior to this change, the firewire driver stack didn't touch retry_limit, and any SBP-3 compliant device worked fine, while SBP-2 compliant ones were unable to retransmit when the host returned an ack_busy_X, which resulted in stalled out I/O, eventually causing the SCSI layer to give up and offline the device. The simple fix is for us to set retry_limit to 0xf in the register for all devices (which actually matches what the old ieee1394 stack did). Prior to this change, a hard disk behind an SBP-2 Prolific PL-3507 bridge chip would routinely encounter buffer I/O errors and wind up offlined by the SCSI layer. With this change, I've encountered zero I/O failures moving tens of GB of data around. Signed-off-by: Jarod Wilson <jwilson@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
