x86: fix warning on 32-bit non-PAE
Fix the warning: include2/asm/pgtable.h: In function `pte_modify': include2/asm/pgtable.h:290: warning: left shift count >= width of type On 32-bit PAE the virtual and physical addresses are both 32-bits, so it ends up evaluating 1<<32. Do the shift as a 64-bit shift then cast to the appropriate size. This should all be done at compile time, and so have no effect on generated code.
