Matthew Wilcox (Oracle) 4e140f59d2 mm/usercopy: Check kmap addresses properly
If you are copying to an address in the kmap region, you may not copy
across a page boundary, no matter what the size of the underlying
allocation.  You can't kmap() a slab page because slab pages always
come from low memory.
