Subject: USB: ftdi_sio: fix DTR/RTS line modes
From: Daniel Mack <daniel@caiaq.de>
commit 6a1a82df91fa0eb1cc76069a9efe5714d087eccd upstream.
Call set_mctrl() and clear_mctrl() according to the flow control mode
selected. This makes serial communication for FT232 connected devices
work when CRTSCTS is not set.
This fixes a regression introduced by 4175f3e31 ("tty_port: If we are
opened non blocking we still need to raise the carrier"). This patch
calls the low-level driver's dtr_rts() function which consequently sets
TIOCM_DTR | TIOCM_RTS. A later call to set_termios() without CRTSCTS in
cflags, however, does not reset these bits, and so data is not actually
sent out on the serial wire.

Subject: HID: usbhid: enable remote wakeup for keyboards
From: Alan Stern <stern@rowland.harvard.edu>
commit 3d61510f4ecacfe47c75c0eb51c0659dfa77fb1b upstream.
This patch (as1365) enables remote wakeup by default for USB keyboard
devices. Keyboards in general are supposed to be wakeup devices, but
the correct place to enable it depends on the device's bus; no single
approach will work for all keyboard devices. In particular, this
covers only USB keyboards (and then only those supporting the boot
protocol).

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
From: Chris Wilson <chris@chris-wilson.co.uk>
commit 468f0b44ce4b002ca7d9260f802a341854752c02 upstream.
Delay taking the mutex until we need to and ensure that we hold the
spinlock when resetting unpin_work on the error path. Also defer the
debugging print messages until after we have released the spinlock.

Subject: amd64-agp: Probe unknown AGP devices the right way
From: Ben Hutchings <ben@decadent.org.uk>
commit 6fd024893911dcb51b4a0aa71971db5ba38f7071 upstream.
The current initialisation code probes 'unsupported' AGP devices
simply by calling its own probe function. It does not lock these
devices or even check whether another driver is already bound to
them.
We must use the device core to manage this. So if the specific
device id table didn't match anything and agp_try_unsupported=1,
switch the device id table and call driver_attach() again.

Subject: perf: Fix endianness argument compatibility with OPT_BOOLEAN() and introduce OPT_INCR()
From: Ian Munsie <imunsie@au.ibm.com>
commit c05556421742eb47f80301767653a4bcb19de9de upstream.
Parsing an option from the command line with OPT_BOOLEAN on a
bool data type would not work on a big-endian machine due to the
manner in which the boolean was being cast into an int and
incremented. For example, running 'perf probe --list' on a
PowerPC machine would fail to properly set the list_events bool
and would therefore print out the usage information and
terminate.
This patch makes OPT_BOOLEAN work as expected with a bool
datatype. For cases where the original OPT_BOOLEAN was
intentionally being used to increment an int each time it was
passed in on the command line, this patch introduces OPT_INCR
with the old behaviour of OPT_BOOLEAN (the verbose variable is
currently the only such example of this).
I have reviewed every use of OPT_BOOLEAN to verify that a true
C99 bool was passed. Where integers were used, I verified that
they were only being used for boolean logic and changed them to
bools to ensure that they would not be mistakenly used as ints.
The major exception was the verbose variable which now uses
OPT_INCR instead of OPT_BOOLEAN.

Subject: drm/i915: Kill dangerous pending-flip debugging
From: Chris Wilson <chris@chris-wilson.co.uk>
commit 9908ff736adf261e749b4887486a32ffa209304c upstream.
We can, by virtue of a vblank interrupt firing in the middle of setting
up the unpin work (i.e. after we set the unpin_work field and before we
write to the ringbuffer) enter intel_finish_page_flip() prior to
receiving the pending flip notification. Therefore we can expect to hit
intel_finish_page_flip() under normal circumstances without a pending flip
and even without installing the pending_flip_obj. This is exacerbated by
aperture thrashing whilst binding the framebuffer
References:
Bug 28079 - "glresize" causes kernel panic in intel_finish_page_flip.

Subject: drm/i915: Rebind bo if currently bound with incorrect alignment.
From: Chris Wilson <chris@chris-wilson.co.uk>
commit ac0c6b5ad3b3b513e1057806d4b7627fcc0ecc27 upstream.
Whilst pinning the buffer, check that that its current alignment
matches the requested alignment. If it does not, rebind.
This should clear up any final render errors whilst resuming,

Subject: drm/i915: Reject bind_to_gtt() early if object > aperture
From: Chris Wilson <chris@chris-wilson.co.uk>
commit 654fc6073f68efa3b6c466825749e73e7fbb92cd upstream.
If the object is bigger than the entire aperture, reject it early
before evicting everything in a vain attempt to find space.
v2: Use E2BIG as suggested by Owain G. Ainsworth.
