[PATCH] direct_remap_pfn_range vm_flags fix
direct_remap_pfn_range() does not properly mark vma with VM_PFNMAP.
This triggers improper reference counting on what rmap thought was
a normal page, and a subsequent BUG() such as:
Eeek! page_mapcount(page) went negative! (-1)
page->flags = 414
page->count = 1
page->mapping = 00000000
