Checking whether the machine is using ECC enabled DRAM is done through testing the DimmEccEn bit in the DRAM Cfg Low register (F2x[1,0]90). Do that instead of testing all bits from the DimmEccEn upwards. Also, remove mci->edac_cap assignment and use value returned from amd64_determine_edac_cap().

2009-06-26powerpc/pmac: Fix DMA ops for MacIO devicesBenjamin Herrenschmidt1-0/+11
The macio_dev's created to map devices inside the MacIO ASICs don't have proper dma_ops. This causes crashes on some machines since the SCSI code calls dma_map_* on our behalf using the device we hang from. This fixes it by copying the parent PCI device dma_ops into the macio_dev when creating it. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2009-06-26ACPI: video: prevent NULL deref in acpi_get_pci_dev()Troy Moure1-1/+1
ref: http://thread.gmane.org/gmane.linux.kernel/857228/focus=857468 When the ACPI video driver initializes, it does a namespace walk looking for for supported devices. When we find an appropriate handle, we walk up the ACPI tree looking for a PCI root bus, and then walk back down the PCI bus, assuming that every device inbetween is a P2P bridge. This assumption is not correct, and is reported broken on at least: Dell Latitude E6400 ThinkPad X61 Dell XPS M1330 Add a NULL deref check to prevent boot panics.

2009-06-26eeepc-laptop: Register as a pci-hotplug deviceCorentin Chary2-0/+89
The eee contains a logically (but not physically) hotpluggable PCIe slot. Currently this is handled by adding or removing the PCI device in response to rfkill events, but if a user has forced pciehp to bind to it (with the force=1 argument) then both drivers will try to handle the event and hilarity (in the form of oopses) will ensue. This can be avoided by having eee-laptop register the slot as a hotplug slot. Only one of pciehp and eee-laptop will successfully register this, avoiding the problem.

2009-06-25usb_serial: Fix oops when unexisting usb serial device is opened.Thadeu Lima de Souza Cascardo1-0/+3
This commit 335f8514f200e63d689113d29cb7253a5c282967 has stopped properly checking if there is any usb serial associated with the tty in the close function. It happens the close function is called by releasing the terminal right after opening the device fails. As an example, open fails with a non-existing device, when probe has never been called, because the device has never been plugged. This is common in systems with static modules and no udev.

2009-06-24Staging: octeon-ethernet: Fix race freeing transmit buffers.David Daney4-66/+106
The existing code had the following race: Thread-1 Thread-2 inc/read in_use inc/read in_use inc tx_free_list[qos].len inc tx_free_list[qos].len The actual in_use value was incremented twice, but thread-1 is going to free memory based on its stale value, and will free one too many times. The result is that memory is freed back to the kernel while its packet is still in the transmit buffer. If the memory is overwritten before it is transmitted, the hardware will put a valid checksum on it and send it out (just like it does with good packets). If by chance the TCP flags are clobbered but not the addresses or ports, the result can be a broken TCP stream. The fix is to track the number of freed packets in a single location (a Fetch-and-Add Unit register). That way it can never get out of sync with itself. We try to free up to MAX_SKB_TO_FREE (currently 10) buffers at a time. If fewer are available we adjust the free count with the difference. The action of claiming buffers to free is atomic so two threads cannot claim the same buffers. Signed-off-by: David Daney <ddaney@caviumnetworks.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2009-06-24ide cs5520: Initialize second port's interrupt number.David S. Miller1-0/+1
In 86ccf37c6acd74cf7e4b7751ee045de19943c5a0 the driver was modified to deal with the removal of the pciirq argument to ide_pci_setup_ports(). But in the conversion only the first port's IRQ gets setup. Inspired by a patch by Bartlomiej Zolnierkiewicz., and with help from Alan Cox. Signed-off-by: David S. Miller <davem@davemloft.net>

Make hwif->rq point to PM request during PM sequence and do not allow any other types of requests to slip in (the old comment was never correct as there should be no such requests generated during PM sequence).

2009-06-24ide: relax DMA info validity checkingBartlomiej Zolnierkiewicz2-24/+0
There are some broken devices that report multiple DMA xfer modes enabled at once (ATA spec doesn't allow it) but otherwise work fine with DMA so just delete ide_id_dma_bug(). [ As discovered by detective work by Frans and Bart, due to how handling of the ID block was handled before commit c419993 ("ide-iops: only clear DMA words on setting DMA mode") this check was always seeing zeros in the fields or other similar garbage. Therefore this check wasn't actually checking anything. Now that the tests actually check the real bits, all we see are devices that trigger the check yet work perfectly fine, therefore killing this useless check is the best thing to do. -DaveM ] Reported-by: Frans Pop <elendil@planet.nl> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com> Signed-off-by: David S.

2009-06-24ide-cd: Improve "weird block size" error messageFrans Pop1-3/+2
Currently the error gets repeated too frequently, for example each time HAL polls the device when a disc is present. Avoid that by using printk_once instead of printk. Also join the error and corrective action messages into a single line. Signed-off-by: Frans Pop <elendil@planet.nl> Acked-by: Borislav Petkov <petkovbb@gmail.com> Signed-off-by: David S.

2009-06-24ide-cd: Don't warn on bogus block size unless it actually matters.David S. Miller1-1/+4
Frans Pop reported that his CDROM drive reports a blocksize of 2352, and this causes new warnings due to commit e8e7b9eb11c34ee18bde8b7011af41938d1ad667 ("ide-cd: fix oops when using growisofs"). What we're trying to do is make sure that "blocklen >> SECTOR_BITS" is something the block layer won't choke on. And for Frans' case "2352 >> SECTOR_BITS" is equal to "2048 >> SECTOR_BITS", and thats "4". So warning in this case gives no real benefit.

2009-06-24ide: fix handling of unexpected IRQs vs request_irq()Bartlomiej Zolnierkiewicz1-3/+20
Add ide_host_enable_irqs() helper and use it in ide_host_register() before registering ports. Then remove no longer needed IRQ unmasking from in init_irq(). This should fix the problem with "screaming" shared IRQ on the first port (after request_irq() call while we have the unexpected IRQ pending on the second port) which was uncovered by my rework of the serialized interfaces support.

I found a little bug. When configure in ifcfg-eth* is ONBOOT=no, the behavior of ethtool command is wrong. # grep ONBOOT /etc/sysconfig/network-scripts/ifcfg-eth2 ONBOOT=no # ethtool eth2 | tail -n1 Link detected: yes I think "Link detected" should be "no".
