media: videobuf2-core: add error handling for fence

Vb2-core supports in-fence and out-fence for buffer synchronization.
However, in-fence might not be signaled by unexpected situation. Current
logic is waiting for fence signaling infinitely.

This patch added timer when in-fence without signaled is coming, and it
will be expired if callback for in-fence would not be called, which
means in-fence was not signaled during 1000 ms. This case is timeout and
buffer is passed into driver by buf_queue callback, however, it would be
marked with error status.

To support this error handling, vb2-core logic is changed to use
workqueue to avoid calling buf_queue callback in interrupt context.

g2d: fix using virt_to_phys against stack variable

If CONFIG_VMAP_STACK is enabled, kernel stack is not physically linear
any more. Instead, it is allocated from vmap area and virt_to_phys and
similar macros are not available on that area.

G2D driver needs to get phyical address of a structure that describes
job properties to deliver the information to the secure world if G2D
H/W is not capable of protecting secure content leak.

Instead allocating the descriptor from the kernel stack, it is now
placed in g2d_task. It helps reducing data redundancy because all
values of the descriptor are also stored in g2d_task.

g2d: handle fence errors

dma_fence supports delivering error to the fence waiters. The fences
with error are also signaled like good fences. The waiters then should
check if the signaled fence has error status.
G2D driver now checks the status of all signaled before pushing a task
to H/W. If it finds an error from  the fences, it does not run H/W with
the task and push the back to the free task pool after resolving all
acquired resources including fences attached to the task. If the task
has a release fence, it is also signaled with -EIO error status.
G2D driver also signals release fences with error status when the a
fence is timed out or H/W does not incur interrupt until the deadline.
Signaling release fence with an error is helpful for the system
stability because the reader of the G2D output can determine if the
data from G2D is complete.

[ Upstream commit d13a0139d7874a0577b5955d6eed895517d23b72 ]

Fixes vb2_vmalloc_get_userptr() to ioremap correct area.
Since the current code does ioremap the page address, if the offset > 0,
it does not do ioremap the last page and results in kernel panic.

This fixes to pass the size + offset to ioremap so that ioremap
can map correct area. Also, this uses __pfn_to_phys() to get the physical
address of given PFN.

[9610] tcp: clear tp->packets_out when purging write queue

Clear tp->packets_out when purging the write queue, otherwise
tcp_rearm_rto() mistakenly assumes TCP write queue is not empty.
This results in NULL pointer dereference.

Also, remove the redundant `tp->packets_out = 0` from
tcp_disconnect(), since tcp_disconnect() calls
tcp_write_queue_purge().
