Problem:
kernel crash in check_page_to_cma
Solution:
The problem is that page_mapping function returns a invalid mapping
pointer, when a compound page is building while a compaction is doing
at same time, there will have a risk of compound page status checking.
page->mapping is set to TAIL_MAPPING first then set compound header.
But check_page_to_cma don't check real status of page, which caused
panic

Problem:
Due to the post-positioning of di,
the vb2 buffer is directly thrown from the decoder to the upper layer.
Since each vb2 buffer can only be returned by the upper layer,
it can be thrown to the upper layer again. For interlaced streams,
two fields need to be output, so the second field cannot be output.
Solution:
The capture dma buffer is allocated in the decoder.
uvm only allocates an empty shell,
which is actually allocated by the decoder and replaces the dma buffer.
