thinkpad-acpi: recognize latest V-Series using DMI_BIOS_VENDOR

2013-06-07T19:49:49Z

commit a4f46bb9fa84642e356898ee44b670989622f8bb upstream. In the latest V-series bios DMI_PRODUCT_VERSION does not contain the string Lenovo or Thinkpad, but is set to the model number, this causes the thinkpad_acpi module to fail to load. Recognize laptop as Lenovo using DMI_BIOS_VENDOR instead, which is set to Lenovo.

iommu/amd: Workaround for ERBT1312

2013-06-07T19:49:48Z

commit d3263bc29706e42f74d8800807c2dedf320d77f1 upstream. Work around an IOMMU hardware bug where clearing the EVT_INT or PPR_INT bit in the status register may race with the hardware trying to set it again. When not handled the bit might not be cleared and we lose all future event or ppr interrupts. Reported-by: Suravee Suthikulpanit Signed-off-by: Joerg Roedel Signed-off-by: Greg Kroah-Hartman

iommu/amd: Re-enable IOMMU event log interrupt after handling.

2013-06-07T19:49:35Z

commit 925fe08bce38d1ff052fe2209b9e2b8d5fbb7f98 upstream. Current driver does not clear the IOMMU event log interrupt bit in the IOMMU status register after processing an interrupt. This causes the IOMMU hardware to generate event log interrupt only once. This has been observed in both IOMMU v1 and V2 hardware. This patch clears the bit by writing 1 to bit 1 of the IOMMU status register (MMIO Offset 2020h) Signed-off-by: Suravee Suthikulpanit Signed-off-by: Joerg Roedel Signed-off-by: Greg Kroah-Hartman

xen/events: Handle VIRQ_TIMER before any other hardirq in event loop.

2013-06-07T19:49:34Z

commit bee980d9e9642e96351fa3ca9077b853ecf62f57 upstream. This avoids any other hardirq handler seeing a very stale jiffies value immediately after wakeup from a long idle period. The one observable symptom of this was a USB keyboard, with software keyboard repeat, which would always repeat a key immediately that it was pressed. This is due to the key press waking the guest, the key handler immediately runs, sees an old jiffies value, and then that jiffies value significantly updated, before the key is unpressed.

libata: make ata_exec_internal_sg honor DMADIR

2013-06-07T19:49:33Z

commit e771451c0a831d96a7c14b0ca8a8ec671d98567b upstream. libata honors DMADIR for regular commands, but not for internal commands used (among other) during device initialisation.

USB: io_ti: Fix NULL dereference in chase_port()

2013-06-07T19:49:32Z

commit 1ee0a224bc9aad1de496c795f96bc6ba2c394811 upstream. The tty is NULL when the port is hanging up. chase_port() needs to check for this. This patch is intended for stable series. The behavior was observed and tested in Linux 3.2 and 3.7.1. Johan Hovold submitted a more elaborate patch for the mainline kernel.

If a key was larger than 64 bytes, as checked by iscsi_check_key(), the error response packet, generated by iscsi_add_notunderstood_response(), would still attempt to copy the entire key into the packet, overflowing the structure on the heap.
