Sprinkle a few more .set mipsX over xchg to make sure we dont' end up with

64-bit instructions on 32-bit processors, they tend to be unhappy about

in http://www.linux-mips.org/cgi-bin/mesg.cgi?a=linux-mips&i=200508171321.20094.Joshua.Wise%40sicortex.com and it's the right thing to do anyway because
it was inflating those functions way too much.

On CONFIG_64BIT_PHYS_ADDR, pfn always fits in 'unsigned long', but
...
pfn<<PAGE_SHIFT sometimes extends beyond. The pte is big enough to hold
'long long', but the shift in pfn_pte() needs to do its calculation with
enough bits to hold the result.
