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
