Fix formatting on r8169 printk Brandon Philips noted that I had a spacing issue in my printk for the last r8169 patch that made it quite ugly.

* md: deal with merge_bvec_fn in component devices better.NeilBrown2010-04-26
| | | | | | | | | | | | | | | | | | | | commit 627a2d3c29427637f4c5d31ccc7fcbd8d312cd71 upstream. If a component device has a merge_bvec_fn then as we never call it we must ensure we never need to. Currently this is done by setting max_sector to 1 PAGE, however this does not stop a bio being created with several sub-page iovecs that would violate the merge_bvec_fn. So instead set max_phys_segments to 1 and set the segment boundary to the same as a page boundary to ensure there is only ever one single-page segment of IO requested at a time. This can particularly be an issue when 'xen' is used as it is known to submit multiple small buffers in a single bio.

* ACPI: EC: Limit burst to 64 bitsAlexey Starikovskiy2010-04-26
| | | | | | | | | | | | | | | | | | | | commit 2060c44576c79086ff24718878d7edaa7384a985 upstream. access_bit_width field is u8 in ACPICA, thus 256 value written to it becomes 0, causing divide by zero later. Proper fix would be to remove access_bit_width at all, just because we already have access_byte_width, which is access_bit_width / 8. Limit access width to 64 bit for now. https://bugzilla.kernel.org/show_bug.cgi?id=15749 fixes regression caused by the fix for: https://bugzilla.kernel.org/show_bug.cgi?id=14667 Signed-off-by: Alexey Starikovskiy <astarikovskiy@suse.de> Signed-off-by: Len Brown <len.brown@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* iwlwifi: fix scan raceReinette Chatre2010-04-26
| | | | | | | | | | | | | | | | | | | | | | | commit bbcbb9ef9735c67da303d30bd6beb9e699f0f508 upstream. There is a problem if an "internal short scan" is in progress when a mac80211 requested scan arrives. If this new scan request arrives within the "next_scan_jiffies" period then driver will immediately return success and complete the scan. The problem here is that the scan has not been fully initialized at this time (is_internal_short_scan is still set to true because of the currently running scan), which results in the scan completion never to be sent to mac80211. At this time also, evan though the internal short scan is still running the state (is_internal_short_scan) will be set to false, so when the internal scan does complete then mac80211 will receive a scan completion. Fix this by checking right away if a scan is in progress when a scan request arrives from mac80211.

* b43: fall back gracefully to PIO mode after fatal DMA errorsLinus Torvalds2010-04-26
| | | | | | | | | | | | | | | | | | | | | | commit 9e3bd9190800e8209b4a3e1d724c35f0738dcad2 upstream. This makes the b43 driver just automatically fall back to PIO mode when DMA doesn't work. The driver already told the user to do it, so rather than have the user reload the module with a new flag, just make the driver do it automatically. We keep the message as an indication that something is wrong, but now just automatically fall back to the hopefully working PIO case.

* b43: Allow PIO mode to be selected at module loadLarry Finger2010-04-26
| | | | | | | | | | | | | | | | | | | | commit b02914af4d7020828ce921a572589dd793517c09 upstream. If userencounter the "Fatal DMA Problem" with a BCM43XX device, and still wish to use b43 as the driver, their only option is to rebuild the kernel with CONFIG_B43_FORCE_PIO. This patch removes this option and allows PIO mode to be selected with a load-time parameter for the module. Note that the configuration variable CONFIG_B43_PIO is also removed. Once the DMA problem with the BCM4312 devices is solved, this patch will likely be reverted.

* IPoIB: Fix TX queue lockup with mixed UD/CM trafficEli Cohen2010-04-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | commit f0dc117abdfa9a0e96c3d013d836460ef3cd08c7 upstream. The IPoIB UD QP reports send completions to priv->send_cq, which is usually left unarmed; it only gets armed when the number of outstanding send requests reaches the size of the TX queue. This arming is done only in the send path for the UD QP. However, when sending CM packets, the net queue may be stopped for the same reasons but no measures are taken to recover the UD path from a lockup. Consider this scenario: a host sends high rate of both CM and UD packets, with a TX queue length of N. If at some time the number of outstanding UD packets is more than N/2 and the overall outstanding packets is N-1, and CM sends a packet (making the number of outstanding sends equal N), the TX queue will be stopped. When all the CM packets complete, the number of outstanding packets will still be higher than N/2 so the TX queue will not be restarted. Fix this by calling ib_req_notify_cq() when the queue is stopped in the CM path.

We know that with our M225 line of SSDs you sometimes need to disable NCQ (native command queuing) to avoid just the type of errors you're seeing. Our recommendation for the M225 is to add libata.force=noncq to your Linux kernel boot options, under the kernel ATA library option. I have sent your feedback to the engineers working on the C300, and asked them to please pass it on to the firmware team. I have been notified that they are in the process of testing and finalizing a new firmware version, that you can expect to see released around the end of April. We’ll keep you posted as to when it will be available for download. So, turn off NCQ on the drive w/ the current firmware revision.

* raw: fsync method is now requiredAnton Blanchard2010-04-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 55ab3a1ff843e3f0e24d2da44e71bffa5d853010 upstream. Commit 148f948ba877f4d3cdef036b1ff6d9f68986706a (vfs: Introduce new helpers for syncing after writing to O_SYNC file or IS_SYNC inode) broke the raw driver. We now call through generic_file_aio_write -> generic_write_sync -> vfs_fsync_range. vfs_fsync_range has: if (!fop || !fop->fsync) { ret = -EINVAL; goto out; } But drivers/char/raw.c doesn't set an fsync method. We have two options: fix it or remove the raw driver completely. I'm happy to do either, the fact this has been broken for so long suggests it is rarely used. The patch below adds an fsync method to the raw driver. My knowledge of the block layer is pretty sketchy so this could do with a once over. If we instead decide to remove the raw driver, this patch might still be useful as a backport to 2.6.33 and 2.6.32.

* libiscsi: Fix recovery slowdown regressionMike Christie2010-04-26
| | | | | | | | | | | | | | | | | | | | | | | commit 4ae0a6c15efcc37e94e3f30e3533bdec03c53126 upstream. We could be failing/stopping a connection due to libiscsi starting recovery/cleanup, but the xmit path or scsi eh thread path could be dropping the connection at the same time. As a result the session->state gets set to failed instead of in recovery. We end up not blocking the session and so the replacement timeout never gets started and we only end up failing the IO when scsi_softirq_done sees that the cmd has been running for (cmd->allowed + 1) * rq->timeout secs. We used to fail the IO right away so users are seeing a long delay when using dm-multipath. This problem was added in 2.6.28.
