[LinuxPPS] LinuxPPS (RESUBMIT 5-rc1): the PPS Linux implementation.

[Rodolfo Giometti]

Hello,

the latest kernel release has some changes into tty structure so we
need test these patches again! :'(

Be sure to test them against __latest__ kernel release (you can
download it by using GIT). For your information I made the patches
over commit 8be1a6d6c77ab4532e4476fdb8177030ef48b52c.

Please, test and report.

Ciao,

Rodolfo
