commit 481535c5b41d191b22775a6873de5ec0e1cdced1 upstream.

fast_second_level_miss handler for the TLBTEMP area has an assumption
that page table directory entry for the TLBTEMP address range is 0. For
it to be true the TLBTEMP area must be aligned to 4MB boundary and not
share its 4MB region with anything that may use a page table. This is
not true currently: TLBTEMP shares space with vmalloc space which
results in the following kinds of runtime errors when
fast_second_level_miss loads page table directory entry for the vmalloc
space instead of fixing up the TLBTEMP area:
