When xhci_discover_or_reset_device() is called after a host controller power loss, the virtual device may need to be reallocated. Make sure xhci_alloc_dev() uses GFP_NOIO. This avoid causing a deadlock by allowing the kernel to flush pending I/O while reallocating memory for a virtual device for a USB mass storage device that's holding the backing store for dirty memory buffers. This patch should be queued for the 2.6.37 stable tree. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Cc: stable@kernel.org

When there's an xHCI host power loss after a suspend from memory, the USB core attempts to reset and verify the USB devices that are attached to the system. The xHCI driver has to reallocate those devices, since the hardware lost all knowledge of them during the power loss. When a hub is plugged in, and the host loses power, the xHCI hardware structures are not updated to say the device is a hub. This is usually done in hub_configure() when the USB hub is detected. That function is skipped during a reset and verify by the USB core, since the core restores the old configuration and alternate settings, and the hub driver has no idea this happened. This bug makes the xHCI host controller reject the enumeration of low speed devices under the resumed hub. Therefore, make the USB core re-setup the internal xHCI hub device information by calling update_hub_device() when hub_activate() is called for a hub reset resume. After a host power loss, all devices under the roothub get a reset-resume or a disconnect. This patch should be queued for the 2.6.37 stable tree.

Synchronize the interrupts instead of free them in xhci_suspend(). This will prevent a double free when the host is suspended and then the card removed. Set the flag hcd->msix_enabled when using MSI-X, and check the flag in suspend_common(). MSI-X synchronization will be handled by xhci_suspend(), and MSI/INTx will be synchronized in suspend_common(). This patch should be queued for the 2.6.37 stable tree.

The original code that resumed the USB bus on a port status change would only do so when there was a device connected to the port. If a device was just disconnected, the event would be queued for khubd, but khubd wouldn't run. That would leave the connect status change (CSC) bit set. If a USB device was plugged into that same port, the xHCI host controller would set the current connect status (CCS) bit. But since the CSC bit was already set, it would not generate an interrupt for a port status change event. That would mean the user could "Safely Remove" a device, have the bus suspend, disconnect the device, re-plug it in, and then the device would never be enumerated. Plugging in a different device on another port would cause the bus to resume, and khubd would notice the re-connected device. Running lsusb would also resume the bus, leading users to report the problem "went away" when using diagnostic tools. The solution is to resume the bus when a port status change event is received, regardless of the port status. Thank you very much to Maddog for helping me track down this Heisenbug. This patch should be queued for the 2.6.37 stable tree.

Xen does not currently expose PV-NUMA information to PV guests. Therefore disable NUMA for the time being to prevent the kernel picking up on an host-level NUMA information which it might come across in the firmware.

nilfs_dat_inode function was a wrapper to switch between normal dat inode and gcdat, a clone of the dat inode for garbage collection. This function got obsolete when the gcdat inode was removed, and now we can access the dat inode directly from a nilfs object. So, we will unfold the wrapper and remove it.

This removes argument for passing nilfs_sb_info structure from nilfs_set_file_dirty and nilfs_load_inode_block functions. We can get a pointer to the structure from inodes.
