Roland,
You can kill your roland/nptl-hppa branch, this merges those changes
to master and tweaks what is required. Thanks again for doing all the
machine work, you are truly a defender of free software!
Committed.
Cheers,
Carlos.

commit 77708643e0896460e1b8a57115af894e3a2d5497

HPPA: Transition to new non-addon NPTL.
Merge roland/nptl-hppa to master, update and test for hppa-linux-gnu.
This commit squashes and commits the work done by Roland McGrath on
roland/nptl-hppa to migrate hppa to the new non-addon NPTL. Some
additional tweaks were required for tcb-offsets.sym to work correctly
along with clone.S (unique to hppa).
