What is your linus/master right now? I get many more merges than you
did.

git tells me that nothing changed in netfront (or netback) in this
range, nor drivers/xen or arch/x86/xen

What is xennet_poll+0x980 in your symbols? There's a lot of inlining
going on in this function so I can't make a sensible by-eye guess.

Nothing leaps out from DaveMs merge. I think you might have to keep
bisecting.
