According to Section 8.5.3.2 of the USB 2.0 specification,
a USB device must terminate a Data Phase with either a
short packet or a ZLP (if the previous transfer was
a multiple of wMaxPacketSize).
For reference, here's what the USB 2.0 specification, section
8.5.3.2 says:
"
8.5.3.2 Variable-length Data Stage
A control pipe may have a variable-length data phase
in which the host requests more data than is contained
in the specified data structure. When all of the data
structure is returned to the host, the function should
indicate that the Data stage is ended by returning a
packet that is shorter than the MaxPacketSize for the
pipe. If the data structure is an exact multiple of
wMaxPacketSize for the pipe, the function will return
a zero-length packet to indicate the end of the Data
stage.

if our list of requests is empty, return early.
There's really nothing to be done in case our
request list is empty anyway because the only
situation where we our list is empty, is when
we're transferring ZLPs.

On USB20CV's Interface Descriptor Test, a series
of SetInterface/GetInterface requests are issued
and gadget driver is required to always return
correct alternate setting.
In one step of the test, g_serial with f_obex
was returning the wrong value (1 instead of 0).
In order to fix this, we will now hold currently
selected alternate setting inside our struct f_obex
and just return that from our ->get_alt()
implementation.
Note that his also simplifies the code a bit.

If a set_alt() to the same alternate setting that's
already selected is received, functions are required
to reset the interface state, this means we must disable
all endpoints and reenable them again.
This is also documented on our kdoc for struct usb_function
* @set_alt: (REQUIRED) Reconfigures altsettings; function drivers may
* initialize usb_ep.driver data at this time (when it is used).
* Note that setting an interface to its current altsetting resets
* interface state, and that all interfaces have a disabled state.

According to our Gadget Framework API documentation,

A batch of fixes that have come in during the merge window.
Some of them are defconfig updates for things that have now landed,
some errata additions and a few general scattered fixes.
There's also a qcom DT update that adds support for SATA on AP148,
and basic support for Sony Xperia Z1 and CM-QS600 platforms that seemed
isolated enough that we could merge it even if it's late.

Pull audit updates from Eric Paris:
"So this change across a whole bunch of arches really solves one basic
problem. We want to audit when seccomp is killing a process. seccomp
hooks in before the audit syscall entry code. audit_syscall_entry
took as an argument the arch of the given syscall. Since the arch is
part of what makes a syscall number meaningful it's an important part
of the record, but it isn't available when seccomp shoots the
syscall...
For most arch's we have a better way to get the arch (syscall_get_arch)
So the solution was two fold: Implement syscall_get_arch() everywhere
there is audit which didn't have it. Use syscall_get_arch() in the
seccomp audit code. Having syscall_get_arch() everywhere meant it was
a useless flag on the stack and we could get rid of it for the typical
syscall entry.
The other changes inside the audit system aren't grand, fixed some
records that had invalid spaces. Better locking around the task comm
field. Removing some dead functions and structs. Make some things
static. Really minor stuff"

This breaks the stack end corruption detection facility.
What that facility does it write a magic value to "end_of_stack()"
and checking to see if it gets overwritten.
"end_of_stack()" is "task_thread_info(p) + 1", which for sparc64 is
the beginning of the FPU register save area.
So once the user uses the FPU, the magic value is overwritten and the
debug checks trigger.
Fix this by making the size explicit.
Due to the size we use for the fpsaved[], gsr[], and xfsr[] arrays we
are limited to 7 levels of FPU state saves. So each FPU register set
is 256 bytes, allocate 256 * 7 for the fpregs area.

Every path that ends up at do_sparc64_fault() must install a valid
FAULT_CODE_* bitmask in the per-thread fault code byte.
Two paths leading to the label winfix_trampoline (which expects the
FAULT_CODE_* mask in register %g4) were not doing so:
1) For pre-hypervisor TLB protection violation traps, if we took
the 'winfix_trampoline' path we wouldn't have %g4 initialized
with the FAULT_CODE_* value yet. Resulting in using the
TLB_TAG_ACCESS register address value instead.
2) In the TSB miss path, when we notice that we are going to use a
hugepage mapping, but we haven't allocated the hugepage TSB yet, we
still have to take the window fixup case into consideration and
in that particular path we leave %g4 not setup properly.
Errors on this sort were largely invisible previously, but after
commit 4ccb927289 ("sparc64: sun4v TLB
error power off events") we now have a fault_code mask bit
(FAULT_CODE_BAD_RA) that triggers due to this bug.
FAULT_CODE_BAD_RA triggers because this bit is set in TLB_TAG_ACCESS
(see #1 above) and thus we get seemingly random bus errors triggered
for user processes.

Pull block layer driver update from Jens Axboe:
"This is the block driver pull request for 3.18. Not a lot in there
this round, and nothing earth shattering.
- A round of drbd fixes from the linbit team, and an improvement in
asender performance.
- Removal of deprecated (and unused) IRQF_DISABLED flag in rsxx and
hd from Michael Opdenacker.
- Disable entropy collection from flash devices by default, from Mike
Snitzer.
- A small collection of xen blkfront/back fixes from Roger Pau Monné
and Vitaly Kuznetsov"
* 'for-3.18/drivers' of git://git.kernel.dk/linux-block:
block: disable entropy contributions for nonrot devices
xen, blkfront: factor out flush-related checks from do_blkif_request()

xen/blkback: unmap all persistent grants when frontend gets disconnected
rsxx: Remove deprecated IRQF_DISABLED
block: hd: remove deprecated IRQF_DISABLED
drbd: use RB_DECLARE_CALLBACKS() to define augment callbacks
drbd: compute the end before rb_insert_augmented()
drbd: Add missing newline in resync progress display in /proc/drbd
drbd: reduce lock contention in drbd_worker
drbd: Improve asender performance
drbd: Get rid of the WORK_PENDING macro
drbd: Get rid of the __no_warn and __cond_lock macros
drbd: Avoid inconsistent locking warning

drbd: Use consistent names for all the bi_end_io callbacks
drbd: Use better variable names
Pull core block layer changes from Jens Axboe:
"This is the core block IO pull request for 3.18. Apart from the new
and improved flush machinery for blk-mq, this is all mostly bug fixes
and cleanups.
- blk-mq timeout updates and fixes from Christoph.
- Removal of REQ_END, also from Christoph. We pass it through the
->queue_rq() hook for blk-mq instead, freeing up one of the request
bits. The space was overly tight on 32-bit, so Martin also killed
REQ_KERNEL since it's no longer used.
- blk integrity updates and fixes from Martin and Gu Zheng.
- Update to the flush machinery for blk-mq from Ming Lei. Now we
have a per hardware context flush request, which both cleans up the
code should scale better for flush intensive workloads on blk-mq.
- Improve the error printing, from Rob Elliott.
- Backing device improvements and cleanups from Tejun.
- Fixup of a misplaced rq_complete() tracepoint from Hannes.
- Make blk_get_request() return error pointers, fixing up issues
where we NULL deref when a device goes bad or missing. From Joe
Lawrence.
- Prep work for drastically reducing the memory consumption of dm
devices from Junichi Nomura. This allows creating clone bio sets
without preallocating a lot of memory.
- Fix a blk-mq hang on certain combinations of queue depths and
hardware queues from me.
- Limit memory consumption for blk-mq devices for crash dump
scenarios and drivers that use crazy high depths (certain SCSI
shared tag setups). We now just use a single queue and limited
depth for that"

Pull MTD update from Brian Norris:
"Sorry for delaying this a bit later than usual. There's one mild
regression from 3.16 that was noticed during the 3.17 cycle, and I
meant to send a fix for it along with this pull request. I'll
probably try to queue it up for a later pull request once I've had a
better look at it, hopefully by -rc2 at the latest.
Summary for this pull:
