I am announcing the release of the 2.6.32.47+drm33.20 longterm tree. This tree is based on 2.6.32 and generally has all of the stable updates applied. Except those to the DRM subsystem, which was based on 2.6.33 and took updates from that upstream stable as long as that existed. It will continue to add patches to the DRM subsystem as long as they are valid according to the stable update rules (Documentation/stable_kernel_rules.txt). DRM patches for this tree should be sent to kernel-team@lists.ubuntu.com. This release contains patches from upstream 2.6.32.47, but dropped any patches to the DRM subsystem. The updated 2.6.32.y-drm33.z tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/smb/linux-2.6.32.y-drm33.z.git or git://kernel.ubuntu.com/smb/linux-2.6.32.y-drm33.z.git and can be browsed through git web via: http://git.kernel.org/?p=linux/kernel/git/smb/linux-2.6.32.y-drm33.z.git;a=summary or http://kernel.ubuntu.com/git?p=smb/linux-2.6.32.y-drm33.z.git;a=summary -Stefan ------ * USB: ftdi_sio: add Calao reference board support * USB: EHCI: Do not rely on PORT_SUSPEND to stop USB resuming in ehci_bus_resume(). * rt2x00: do not drop usb dev reference counter on suspend * atm: br2684: Fix oops due to skb->dev being NULL * sparc: Allow handling signals when stack is corrupted. * sparc: fix array bounds error setting up PCIC NMI trap * Fix broken backport for IPv6 tunnels * net: Fix IPv6 GSO type checks in Intel ethernet drivers * ipv6: Add GSO support on forwarding path * Revert "x86, hotplug: Use mwait to offline a processor, fix the legacy case" * GRO: fix merging a paged skb after non-paged skbs * xen-blkfront: fix data size for xenbus_gather in blkfront_connect * md/linear: avoid corrupting structure while waiting for rcu_free to complete. * powerpc/mpic: Fix problem that affinity is not updated * powerpc/pci: Check devices status property when scanning OF tree * xen: x86_32: do not enable iterrupts when returning from exception in interrupt context * xen/smp: Warn user why they keel over -
