I didn't merge it into 2.6.36 and it's looking doubtful for 2.6.37. 
There were a number of issues identified during review and afaik they
remain up in the air.

My notes-to-self from the series file:

pps-trivial-fixes.patch
pps-declare-variables-where-they-are-used-in-switch.patch
#pps-fix-race-in-pps_fetch-handler.patch: Vitezslav Samel <vitezslav@...el.cz> q, TBU
pps-fix-race-in-pps_fetch-handler.patch
pps-unify-timestamp-gathering.patch
#pps-access-pps-device-by-direct-pointer.patch: Rodolfo issues
pps-access-pps-device-by-direct-pointer.patch
pps-convert-printk-pr_-to-dev_.patch
pps-move-idr-stuff-to-ppsc.patch
pps-add-async-pps-event-handler.patch
pps-add-async-pps-event-handler-fix.patch
pps-dont-disable-interrupts-when-using-spin-locks.patch
pps-use-bug_on-for-kernel-api-safety-checks.patch
pps-simplify-conditions-a-bit.patch
ntp-add-hardpps-implementation.patch
#pps-capture-monotonic_raw-timestamps-as-well.patch: John had Q, TBU
pps-capture-monotonic_raw-timestamps-as-well.patch
pps-add-kernel-consumer-support.patch
pps-add-parallel-port-pps-client.patch
pps-add-parallel-port-pps-signal-generator.patch

(where TBU = "to be updated").

There may be other issues - one would need to go back and review the review
thread.
