#     mm: teach dump_page() to correctly output poisoned struct pages
#     
#     If struct page is poisoned, and uninitialized access is detected via
#     PF_POISONED_CHECK(page) dump_page() is called to output the page.  But,
#     the dump_page() itself accesses struct page to determine how to print
#     it, and therefore gets into a recursive loop.
#     
#     For example:
#     
#       dump_page()
#        __dump_page()
#         PageSlab(page)
#          PF_POISONED_CHECK(page)
#           VM_BUG_ON_PGFLAGS(PagePoisoned(page), page)
#            dump_page() recursion loop.
