2011-06-07Revert "USB: option: add ID for ZTE MF 330"Greg Kroah-Hartman1-5/+0
This reverts commit a559d2c8c1bf652ea2d0ecd6ab4a250fcdb37db8. Turns out that device id 0x1d6b:0x0002 is a USB hub, which causes havoc when the option driver tries to bind to it. So revert this as it doesn't seem to be needed at all. Thanks to Michael Tokarev and Paweł Drobek for working on resolving this issue.

2011-06-07PM / Runtime: Fix loops in pm_runtime_clk_notify()Rafael J. Wysocki1-8/+8
The loops over connection ID strings in pm_runtime_clk_notify() should actually iterate over the strings and not over the elements of the first of them, so make them behave as appropriate. This fixes a regression introduced by commit 600b776eb39a13a28b090 (OMAP1 / PM: Use generic clock manipulation routines for runtime PM).

2011-06-07igb: fix i350 SR-IOV failtureWilliams, Mitch A1-0/+3
When SR-IOV is enabled, i350 devices fail to pass traffic. This is due to the driver attempting to enable RSS on the PF device, which is not supported by the i350. When max_vfs is specified on an i350 adapter, set the number of RSS queues to 1. This issue affects 2.6.39 as well.

2011-06-07libata: fix unexpectedly frozen port after ata_eh_reset()Tejun Heo1-4/+8
To work around controllers which can't properly plug events while reset, ata_eh_reset() clears error states and ATA_PFLAG_EH_PENDING after reset but before RESET is marked done. As reset is the final recovery action and full verification of devices including onlineness and classfication match is done afterwards, this shouldn't lead to lost devices or missed hotplug events. Unfortunately, it forgot to thaw the port when clearing EH_PENDING, so if the condition happens after resetting an empty port, the port could be left frozen and EH will end without thawing it, making the port unresponsive to further hotplug events. Thaw if the port is frozen after clearing EH_PENDING. This problem is reported by Bruce Stenning in the following thread. http://thread.gmane.org/gmane.linux.kernel/1123265 stable: I think we should weather this patch a bit longer in -rcX before sending it to -stable.

2011-06-07staging: gma500: get control from firmware framebuffer if conflictsMichael Chang1-0/+10
Many Linux distributions would enable vesafb in order to display early stage boot splash. In this case, we will get garbled X Window screen if running X fbdev on psbfb. This is because fb0 is occupied by vesafb while psbfb is on fb1. They tried to drive the same pieces of hardware at the same time. With unmodified X start-up, it would try to use default fb0 framebuffer device and unfortunately it is now broken becaues fb1 supersedes it. We should let psbfb takeover framebuffer control from vesafb to get around this problem.

2011-06-07usb-storage: redo incorrect readsAlan Stern6-2/+67
Some USB mass-storage devices have bugs that cause them not to handle the first READ(10) command they receive correctly. The Corsair Padlock v2 returns completely bogus data for its first read (possibly it returns the data in encrypted form even though the device is supposed to be unlocked). The Feiya SD/SDHC card reader fails to complete the first READ(10) command after it is plugged in or after a new card is inserted, returning a status code that indicates it thinks the command was invalid, which prevents the kernel from retrying the read. Since the first read of a new device or a new medium is for the partition sector, the kernel is unable to retrieve the device's partition table. Users have to manually issue an "hdparm -z" or "blockdev --rereadpt" command before they can access the device. This patch (as1470) works around the problem. It adds a new quirk flag, US_FL_INVALID_READ10, indicating that the first READ(10) should always be retried immediately, as should any failing READ(10) commands (provided the preceding READ(10) command succeeded, to avoid getting stuck in a loop). The patch also adds appropriate unusual_devs entries containing the new flag.

2011-06-07x86/amd-iommu: Fix boot crash with hidden PCI devicesJoerg Roedel1-1/+21
Some PCIe cards ship with a PCI-PCIe bridge which is not visible as a PCI device in Linux. But the device-id of the bridge is present in the IOMMU tables which causes a boot crash in the IOMMU driver. This patch fixes by removing these cards from the IOMMU handling. This is a pure -stable fix, a real fix to handle this situation appriatly will follow for the next merge window. Cc: [email protected] # > 2.6.32 Signed-off-by: Joerg Roedel <[email protected]>
2011-06-07net: cpu offline cause napi stallHeiko Carstens1-0/+5
Frank Blaschka reported : <quote> During heavy network load we turn off/on cpus. Sometimes this causes a stall on the network device. Digging into the dump I found out following: napi is scheduled but does not run. From the I/O buffers and the napi state I see napi/rx_softirq processing has stopped because the budget was reached. napi stays in the softnet_data poll_list and the rx_softirq was raised again. I assume at this time the cpu offline comes in, the rx softirq is raised/moved to another cpu but napi stays in the poll_list of the softnet_data of the now offline cpu. Reviewing dev_cpu_callback (net/core/dev.c) I did not find the poll_list is transfered to the new cpu. </quote> This patch is a straightforward implementation of Frank suggestion : Transfert poll_list and trigger NET_RX_SOFTIRQ on new cpu.

2011-06-07bridge: provide a cow_metrics method for fake_opsAlexander Holler1-0/+6
Like in commit 0972ddb237 (provide cow_metrics() methods to blackhole dst_ops), we must provide a cow_metrics for bridges fake_dst_ops as well.

BugLink: https://launchpad.net/bugs/792712 The original reporter states that sound from the internal speakers is inaudible until using the model=auto quirk. This symptom is due to an existing quirk mask for 0x102802b* that uses the model=dell quirk. To limit the possible regressions, leave the existing quirk mask but add a higher priority specific mask for the reporter's PCI SSID.

2011-06-07cifs: silence printk when establishing first session on socketJeff Layton1-1/+1
When signing is enabled, the first session that's established on a socket will cause a printk like this to pop: CIFS VFS: Unexpected SMB signature This is because the key exchange hasn't happened yet, so the signature field is bogus. Don't try to check the signature on the socket until the first session has been established. Also, eliminate the specific check for SMB_COM_NEGOTIATE since this check covers that case too.

The SEQ output functions grab the obj->attrib->hb_spinlock lock of sub-objects found in the hash traversal. These locks are in a different realm than the one used for the irias_objects hash table itself. So put the latter into it's own lockdep class.
