2011-04-19Revert "[media] V4L: videobuf, don't use dma addr as physical"Linus Torvalds1-1/+1
This reverts commit 35d9f510b67b10338161aba6229d4f55b4000f5b. Quoth Jiri Slaby: "It fixes mmap when IOMMU is used on x86 only, but breaks architectures like ARM or PPC where virt_to_phys(dma_alloc_coherent) doesn't work. We need there dma_mmap_coherent or similar (the trickery what snd_pcm_default_mmap does but in some saner way). But this cannot be done at this phase."

2011-04-19block: Remove the extra check in queue_requests_storeTao Ma1-2/+2
In queue_requests_store, the code looks like if (rl->count[BLK_RW_SYNC] >= q->nr_requests) { blk_set_queue_full(q, BLK_RW_SYNC); } else if (rl->count[BLK_RW_SYNC]+1 <= q->nr_requests) { blk_clear_queue_full(q, BLK_RW_SYNC); wake_up(&rl->wait[BLK_RW_SYNC]); } If we don't satify the situation of "if", we can get that rl->count[BLK_RW_SYNC} < q->nr_quests. It is the same as rl->count[BLK_RW_SYNC]+1 <= q->nr_requests. All the "else" should satisfy the "else if" check so it isn't needed actually.

2011-04-19block: get rid of QUEUE_FLAG_REENTERJens Axboe5-54/+20
We are currently using this flag to check whether it's safe to call into ->request_fn(). If it is set, we punt to kblockd. But we get a lot of false positives and excessive punts to kblockd, which hurts performance. The only real abuser of this infrastructure is SCSI. So export the async queue run and convert SCSI over to use that. There's room for improvement in that SCSI need not always use the async call, but this fixes our performance issue and they can fix that up in due time. Signed-off-by: Jens Axboe <[email protected]>
2011-04-19perf, x86: Fix AMD family 15h FPU event constraintsRobert Richter1-3/+17

2011-04-19perf, x86: Fix pre-defined cache-misses event for AMD family 15h cpusAndre Przywara1-1/+1
With AMD cpu family 15h a unit mask was introduced for the Data Cache Miss event (0x041/L1-dcache-load-misses). We need to enable bit 0 (first data cache miss or streaming store to a 64 B cache line) of this mask to proper count data cache misses. Now we set this bit for all families and models. In case a PMU does not implement a unit mask for event 0x041 the bit is ignored.

2011-04-19cfq-iosched: read_lock() does not always imply rcu_read_lock()Jens Axboe1-14/+6
For some configurations of CONFIG_PREEMPT that is not true. So get rid of __call_for_each_cic() and always uses the explicitly rcu_read_lock() protected call_for_each_cic() instead. This fixes a potential bug related to IO scheduler removal or online switching. Thanks to Paul McKenney for clarifying this. Signed-off-by: Jens Axboe <[email protected]>

2011-04-18Bluetooth: Fix keeping the command timer runningVinicius Costa Gomes1-3/+2

2011-04-18Bluetooth: Fix refcount balance for hci connectionVille Tervo1-2/+0
