Accident of history mostly and preserving the fact I wasn't the code author
of the first patch and I played it safe. 2 was initially "reduce risk of
drift if only 1 caller is updated in the future" and by co-incidence made
patch 3 fractionally easier. 3 was written later while checking for any
side-effects of the fix -- namely the !RT_PUSH_IPI is degraded by some
unquantifed and unnecessary factor. That's ok justification but 2-3 are
not complex enough to justify the risk and Yousaf has no objection to
collapsing them.

I'll collapse them into 1.
