Hmm, save_regs() describes what it does: you pass
a pt_regs and it saves registers inside. But it
has also a kind of fixup thing as it also rewinds.
I'm not sure using a fixup thing for the naming
is correct as we are not starting with initial
regs passed to the function (just a raw buffer).
What about perf_save_caller_regs() ?
