This is this:

net/core/pktgen.c:682:2775: error: can't find a register in class 'GENERAL_REGS' while reloading 'asm'
net/core/pktgen.c:682:3153: error: can't find a register in class 'GENERAL_REGS' while reloading 'asm'
net/core/pktgen.c:682:2775: error: 'asm' operand has impossible constraints
net/core/pktgen.c:682:3153: error: 'asm' operand has impossible constraints

Which is a do_div() call.  The relevant code does not appear to have
changed, so this may well be a result of our toolchain changing from
"arm-linux-gcc (GCC) 4.4.0, GNU ld (GNU Binutils) 2.19.1" to
"arm-unknown-linux-gnueabi-gcc (GCC) 4.6.3, GNU ld (GNU Binutils) 2.22".

Anyone have any thoughts?
