git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless John W. Linville says: ==================== Please pull this last(?) batch of fixes intended for 3.6... For the Bluetooth bits, Gustavo says this: "Here goes probably my last update to 3.6. It includes the two patches you were ok last week(from Andrzej Kaczmarek), those are critical ones, and two other fixes one for a system crash and the other for a missing lockdep annotation." The referenced fixes from Andrzej prevent attempts to configure devices that are powered-off. Along with the Bluetooth fixes, there are a couple of 802.11 fixes. Emmanuel Grumbach gives us an iwlwifi fix to prevent releasing an interrupt twice. Luis R. Rodriguez provides a fix for a possible circular lock dependency in the cfg80211 regulatory enforcement code. All of these have been in linux-next for a few days. I hope they are not too late to make the 3.6 release! ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

It is OK to disable the PV guest from accessing NUMA data as right now we do not inject any NUMA node information to the PV guests. When we do get to that point, then this patch will have to be reverted." * Disable PV NUMA support as we do not do anything with it (yet) and it can cause bootup crashes on certain AMD machines. * tag 'stable/for-linus-3.6-rc7-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen: xen/boot: Disable NUMA for PV guests.

2012-09-24PCI: acpiphp: Handle PCIe ports without native hotplug capabilityJiang Liu
Commit 0d52f54e2ef64c189dedc332e680b2eb4a34590a (PCI / ACPI: Make acpiphp ignore root bridges using PCIe native hotplug) added code that made the acpiphp driver completely ignore PCIe root complexes for which the kernel had been granted control of the native PCIe hotplug feature by the BIOS through _OSC. Later commit 619a5182d1f38a3d629ee48e04fa182ef9170052 "PCI hotplug: Always allow acpiphp to handle non-PCIe bridges" relaxed the constraints to allow acpiphp driver handle non-PCIe bridges under such a complex. The constraint needs to be relaxed further to allow acpiphp driver to handle PCIe ports without native PCIe hotplug capability. Some MR-IOV switch chipsets, such PLX8696, support multiple virtual PCIe switches and may migrate downstream ports among virtual switches. To migrate a downstream port from the source virtual switch to the target, the port needs to be hot-removed from the source and hot-added into the target. The pciehp driver can't be used here because there are no slots within the virtual PCIe switch. So acpiphp driver is used to support downstream port migration. A typical configuration is as below: [Root without native PCIe HP] [Upstream port of vswitch without native PCIe HP] [Downstream port of vswitch with native PCIe HP] [PCIe endpoint] Here acpiphp driver will be used to handle root ports and upstream port in the virtual switch, and pciehp driver will be used to handle downstream ports in the virtual switch.

2012-09-24PCI/ACPI: Use acpi_driver_data() rather than searching acpi_pci_rootsTaku Izumi
This patch changes the implementation of acpi_pci_find_root(). We can access acpi_pci_root without scanning acpi_pci_roots list. If hostbridge hotplug is supported, acpi_pci_roots list will be protected by mutex. We should not access acpi_pci_roots list if preventable to lessen deadlock risk.

2012-09-24PCI/ACPI: Use acpi_pci_root info rather than looking it up againTaku Izumi
This patch changes the function signature of walk_root_bridge(). We can omit _STA, _SEG, and _BBN evaluation by passing not acpi_handle but acpi_pci_root. Now that acpi_pci_slot_add() which is the only caller of walk_root_bridge() gets acpi_pci_root structure, changing signature of walk_root_bridge() is reasonable.

2012-09-24PCI/ACPI: Pass acpi_pci_root to acpi_pci_drivers' add/remove interfaceTaku Izumi
This patch changes .add/.remove interfaces of acpi_pci_driver. In the current implementation acpi_handle is passed as a parameter of .add/.remove interface. However, the acpi_pci_root structure contains more useful information than just the acpi_handle. This enables us to avoid some useless lookups in each acpi_pci_driver. Note: This changes interfaces used by acpi_pci_register_driver(), an exported symbol. This patch updates all the in-kernel users, but any out-of-kernel acpi_pci_register_driver() users will need updates.

2012-09-24HID: picoLCD: bounds check in dump_buff_as_hex()Bruno Prémont
Make sure we keep enough space for terminating NUL character after last newline. If we have too much data, replace last byte with '.'s to make overflow visible. Using hex_dump_to_buffer() is not interesting as it adds more overhead and does not append the trailing linefeed.
