The unioned u32 is used for clearing etc. Having the number of
bitfield bits add up to more than 32 is broken, even if benign.

sparse was giving the following warning:
warning: context imbalance in 's3c_hsotg_ep_enable'
- different lock contexts for basic block
we were returning ENOMEM while still holding the spinlock.
The sparse warning was fixed by releasing the spinlock before return.

Currently, there's no guarantee that udc->driver
will be valid when using soft_connect sysfs
interface. In fact, we can very easily trigger
a NULL pointer dereference by trying to disconnect
when a gadget driver isn't loaded.
Fix this bug:

A request allocated from e.g. ep1out cannot
be queued to any other endpoint. This bug has
been in f_loopback at least since mid-2011 and
since nobody has really screamed about it, we're
not backporting to any stable kernels.
Debugged with MUSB since that's the only controller
which complains about this case.

The commit '2e4c7553cd usb: gadget: f_fs: add aio support' broke the
quirk implemented to align buffer size to maxpacketsize on out endpoint.
As result, functionfs does not work on Intel platforms using dwc3 driver

During FunctionFS bind, ffs_data_get() function was called twice
(in functionfs_bind() and in ffs_do_functionfs_bind()), while on unbind
ffs_data_put() was called once (in functionfs_unbind() function).
In result refcount never reached value 0, and ffs memory resources has
been never released.
Since ffs_data_get() call in ffs_do_functionfs_bind() is redundant
and not neccessary, we remove it to have equal number of gets ans puts,
and free allocated memory after refcount reach 0.

prepare/complete"
This reverts commit 02dae36aa649a66c5c6181157ddd806e7b4913fc.
That commit is bogus in two ways:
1) There's no way dwc3-omap's ->suspend() can cause any effect
on xhci's ->suspend(). Linux device driver model guarantees
that a parent's ->suspend() will only be called after all
children are suspended. dwc3-omap is the parent of the
parent of xhci.
2) When implementing Deep Sleep states where context is lost,
USBOTGSS_IRQ0 register, well, looses context so we
_must_ rewrite it otherwise core IRQs will never be
reenabled and USB will appear to be dead.

commit c58d80f52 ("usb: musb: Ensure that cppi41 timer gets armed on
premature DMA TX irq") fixed hrtimer scheduling bug. There is one left
which does not trigger that often.
The following scenario is still possible:
lock(&x->lock);
hrtimer_start(&x->t);
unlock(&x->lock);
expires:
t->function();
lock(&x->lock);
lock(&x->lock); if (!hrtimer_queued(&x->t))
hrtimer_start(&x->t);
unlock(&x->lock);
if (!list_empty(x->early_tx_list))
ret = HRTIMER_RESTART;
-> hrtimer_forward_now(...)
} else
ret = HRTIMER_NORESTART;
unlock(&x->lock);
and the timer callback returns HRTIMER_RESTART for an armed timer. This
is wrong and we run into the BUG_ON() in __run_hrtimer().
This can happens on SMP or PREEMPT-RT.
The patch fixes the problem by only starting the timer if the timer is
not yet queued.

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.

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.

The way trace works is that it won't decode strings
until we read the actual trace. Because of that, we
can't make assumptions of pointers still being valid
at the time we read the trace. In order to avoid that,
just copy all fields from every struct pointer we need
for our traces.

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"

tools that only want system wide mode. (Arnaldo Carvalho de Melo)

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 4ccb9272892c33ef1c19a783cfa87103b30c2784 ("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 second batch of changes for KVM/{arm,arm64} from Marc Zyngier:
"The most obvious thing is the sizeable MMU changes to support 48bit
VAs on arm64.
Summary:
- support for 48bit IPA and VA (EL2)
- a number of fixes for devices mapped into guests
- yet another VGIC fix for BE
- a fix for CPU hotplug
- a few compile fixes (disabled VGIC, strict mm checks)"

backpack was stolen at Düsseldorf airport and will do new keys and
rebuild his web of trust. - Linus ]
