The underlying arm-smmu hardware only supports mapping addresses
aligned to PAGE_SIZE. Thus the actual mapped region may be larger than
the range returned by iommu_map_sg():
[sg_dma_address(), sg_dma_address() + sg->length)
When unmapping, ensure the same alignment requirements are applied
in order to avoid leaking iova addresses.

We are setting event buffer size with the requested size and then
allocating the buffer for event requests (ereqs). But if the memory
allocation for ereq buffer fails, the event-buffer-size variable
is not getting set to zero.
Due to this, if a client calls open channel multiple times,
our logic proceeded without really allocating the buffer for ereqs.
And while processing completion events, we are observing null pointer
dereference issues.

Function fs endpoint file operations are synchronized via an interruptible
mutex wait. However we see threads that do ep file operations concurrently
are getting blocked for the mutex lock in __fdget_pos(). This is an
uninterruptible wait and we see hung task warnings and kernel panic
if hung_task_panic systcl is enabled if host does not send/receive
the data for long time.
The reason for threads getting blocked in __fdget_pos() is due to
the file position protection introduced by the commit 9c225f2655
("vfs: atomic f_pos accesses as per POSIX"). Since function fs
endpoint files does not have the notion of the file position, switch
to the stream mode. This will bypass the file position mutex and
threads will be blocked in interruptible state for the function fs
mutex.
It should not affects user space as we are only changing the task state
changes the task state from UNINTERRUPTIBLE to INTERRUPTIBLE while waiting
for the USB transfers to be finished. However there is a slight change to
the O_NONBLOCK behavior. Earlier threads that are using O_NONBLOCK are also
getting blocked inside fdget_pos(). Now they reach to function fs and error
code is returned. The non blocking behavior is actually honoured now.

kgsl_ioctl_gpu_aux_command creates a separate drawobj for each command
in numcmds sent from userspace. All drawbojs created will have same
timestamp. We can not queue more than one drawobj with same timestamp.
Each new drawobj must have timestamp greater than previously queued
drawobjs. This results in failure of kgsl_ioctl_gpu_aux_command.
Add proper check and return early when numcmds is invalid.

When runtime suspend occurs xhci_suspend is called and now all the
clocks are turned off. Now if pm_suspend happens xhci_suspend is again
called which leads to unclocked access of registers in function
xhci_disable_hub_port_wake. Fix this by considering second
call of xhci_suspend due to pm_suspend as no-op.

Driver core invokes runtime PM idle after the device is probed. When the
runtime idle callback returns 0, platform bus proceed to runtime suspend.
If this races with state machine work which marks the runtime state as
active and enables runtime PM, there is a possibility that the runtime
PM thinks device is suspended. Because the runtime PM suspend patch
returns simply because in_lpm is true. Now, state machine work calls
dwc3_msm_resume() which sets WAIT_FOR_LPM flag hoping that it would be
cleared while runtime suspend happens via pm_runtime_put_sync(). Though
the device is in resume state, runtime PM core thinks it is suspended
due to the race mentioned above. The fact that WAIT_FOR_LPM is set,
state machine for ever stuck in DRD_STATE_IDLE waiting for this flag to
be cleared.
Fix this by calling dwc3_msm_resume before setting device as active so
that the corresponding pm_runtime_put_sync operation happens correctly.

The __UNIQUE_ID() macro causes problems as it turns out to not be
deterministic across different compiler runs as it relies on the
__COUNTER__ macro which could have been used on other .h files previous
to this .h file being included.
This shows up specifically when building with "LTO=thin" vs. "LTO=full"
as different build paths seem to be triggered.
As the structure name isn't really needed at all here, we were just
including it for older compilers that could not handle anonymous
structures in a union, just drop the whole thing which resolves the abi
naming issue.
