+Subject: Bluetooth: Fix not closing SCO sockets in the BT_CONNECT2 state
+
+From: Vinicius Costa Gomes <vinicius.gomes@openbossa.org>
+
+commit eb20ff9c91ddcb2d55c1849a87d3db85af5e88a9 upstream.
+
+With deferred setup for SCO, it is possible that userspace closes the
+socket when it is in the BT_CONNECT2 state, after the Connect Request is
+received but before the Accept Synchonous Connection is sent.
+
+If this happens the following crash was observed, when the connection is
+terminated:

+Subject: tile: expect new initramfs name from hypervisor file system
+
+From: Chris Metcalf <cmetcalf@tilera.com>
+
+commit ff7f3efb9abf986f4ecd8793a9593f7ca4d6431a upstream.
+
+The current Tilera boot infrastructure now provides the initramfs
+to Linux as a Tilera-hypervisor file named "initramfs", rather than
+"initramfs.cpio.gz", as before.  (This makes it reasonable to use
+other compression techniques than gzip on the file without having to
+worry about the name causing confusion.)  Adapt to use the new name,
+but also fall back to checking for the old name.
+
+Cc'ing to stable so that older kernels will remain compatible with
+newer Tilera boot infrastructure.
