+Subject: ext4: check for zero length extent explicitly
+
+From: Eryu Guan <guaneryu@gmail.com>
+
+commit 2f974865ffdfe7b9f46a9940836c8b167342563d upstream.
+
+The following commit introduced a bug when checking for zero length extent
+
+5946d08 ext4: check for overlapping extents in ext4_valid_extent_entries()
+
+Zero length extent could pass the check if lblock is zero.
+
+Adding the explicit check for zero length back.

+This is a preparation commit that will allow to add other criteria

+Subject: libata: Ignore spurious PHY event on LPM policy change
+
+From: Gabriele Mazzotta <gabriele.mzt@gmail.com>
+
+commit 09c5b4803a80a5451d950d6a539d2eb311dc0fb1 upstream.
+
+When the LPM policy is set to ATA_LPM_MAX_POWER, the device might
+generate a spurious PHY event that cuases errors on the link.
+Ignore this event if it occured within 10s after the policy change.
+
+The timeout was chosen observing that on a Dell XPS13 9333 these
+spurious events can occur up to roughly 6s after the policy change.

+
+clkdiv is declared as an u32 but it can be set to a negative value
+causing a huge divisor value. Change its type to int to avoid this case.

+
+From: Anton Blanchard <anton@samba.org>
+
+commit 5e95235ccd5442d4a4fe11ec4eb99ba1b7959368 upstream.
+
+Recent toolchains force the TOC to be 256 byte aligned. We need
+to enforce this alignment in our linker script, otherwise pointers
+to our TOC variables (__toc_start, __prom_init_toc_start) could
+be incorrect.
+
+If they are bad, we die a few hundred instructions into boot.

+
+From: Andy Grover <agrover@redhat.com>
+
+commit 5a7125c64def3b21f8147eca8b54949a60963942 upstream.
+
+See https://bugzilla.redhat.com/show_bug.cgi?id=1025672
+
+We need to put() the reference to the scsi host that we got in
+pscsi_configure_device(). In VIRTUAL_HOST mode it is associated with
+the dev_virt, not the hba_virt.

+Most of kernel code assume that interface array in
+struct usb_configuration is NULL terminated.
+
+When gadget is composed with configfs configuration
+structure may be reused for different functions set.
+
+This bug happens because purge_configs_funcs() sets
+only next_interface_id to 0. Interface array still
+contains pointers to already freed interfaces. If in
+second try we add less interfaces than earlier we
+may access unallocated memory when trying to get
+interface descriptors.

+Subject: USB: visor: Match I330 phone more precisely
+
+From: "Jason A. Donenfeld" <Jason@zx2c4.com>
+
+commit 82ee3aeb9295c5fc37fd2ddf20f13ac2b40ec97d upstream.
+
+Samsung has just released a portable USB3 SSD, coming in a very small
+and nice form factor. It's USB ID is 04e8:8001, which unfortunately is
+already used by the Palm Visor driver for the Samsung I330 phone cradle.
+Having pl2303 or visor pick up this device ID results in conflicts with
+the usb-storage driver, which handles the newly released portable USB3
+SSD.
+
+To work around this conflict, I've dug up a mailing list post [1] from a
+long time ago, in which a user posts the full USB descriptor
+information. The most specific value in this appears to be the interface
+class, which has value 255 (0xff). Since usb-storage requires an
+interface class of 0x8, I believe it's correct to disambiguate the two
+devices by matching on 0xff inside visor.

+Subject: xhci: fix isoc endpoint dequeue from advancing too far on transaction error
+
+From: Mathias Nyman <mathias.nyman@linux.intel.com>
+
+commit d104d0152a97fade389f47635b73a9ccc7295d0b upstream.
+
+Isoc TDs usually consist of one TRB, sometimes two. When all goes well we
+receive only one success event for a TD, and move the dequeue pointer to
+the next TD.
+
+This fails if the TD consists of two TRBs and we get a transfer error
+on the first TRB, we will then see two events for that TD.
+
+Fix this by making sure the event we get is for the last TRB in that TD
+before moving the dequeue pointer to the next TD. This will resolve some
+of the uvc and dvb issues with the
+"ERROR Transfer event TRB DMA ptr not part of current TD" error message

+Subject: xhci: Solve full event ring by increasing TRBS_PER_SEGMENT to 256
+
+From: Mathias Nyman <mathias.nyman@linux.intel.com>
+
+commit 18cc2f4cbbaf825a4fedcf2d60fd388d291e0a38 upstream.
+
+Our event ring consists of only one segment, and we risk filling
+the event ring in case we get isoc transfers with short intervals
+such as webcams that fill a TD every microframe (125us)
+
+With 64 TRB segment size one usb camera could fill the event ring in 8ms.
+A setup with several cameras and other devices can fill up the
+event ring as it is shared between all devices.
+This has occurred when uvcvideo queues 5 * 32TD URBs which then
+get cancelled when the video mode changes. The cancelled URBs are returned
+in the xhci interrupt context and blocks the interrupt handler from
+handling the new events.
+
+A full event ring will block xhci from scheduling traffic and affect all
+devices conneted to the xhci, will see errors such as Missed Service
+Intervals for isoc devices, and  and Split transaction errors for LS/FS
+interrupt devices.
+
+Increasing the TRB_PER_SEGMENT will also increase the default endpoint ring
+size, which is welcome as for most isoc transfer we had to dynamically
+expand the endpoint ring anyway to be able to queue the 5 * 32TDs uvcvideo
+queues.
+
+The default size used to be 64 TRBs per segment
