e97288386a The type of sum in csum_tcpudp_nofold is "unsigned int", so when we assign 
to it in an asm() block, and we're running on a system with 64-bit
registers, it is vitally important that we sign extend it correctly before
returning to C.  Otherwise the stray high bits will be preserved into
csum_fold, and on the SB-1 processor, 32-bit arithmetic on a non
sign-extended register will yield surprising results.
    
This caused incorrect checksums in some UDP packets for NFS root.  The
problem was mild when using a 10.0.1.x IP address, but severe when
using 192.168.1.x.

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.

533330bf7f 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.
