Michal Hocko e3dea38fc8 x86/speculation/l1tf: Fix up pte->pfn conversion for PAE ...

commit e14d7dfb41 upstream.

Jan has noticed that pte_pfn and co. resp. pfn_pte are incorrect for
CONFIG_PAE because phys_addr_t is wider than unsigned long and so the
pte_val reps. shift left would get truncated. Fix this up by using proper
types.

[Just one chunk, again, needed here.  Thanks to Ben and Guenter for
finding and fixing this. - gregkh]
