Yes, it was easily possible to make it 32bit-ready without loosing the accuracy. Nevertheless, in the meantime John Stultz pointed me to the CONFIG_GENERIC_TIME framework, and I implemented it that way: http://git.parisc-linux.org/?p=linux-2.6.git;a=commit;h=b6de83b58b8b07f057deacdef8a95b6c32d1c4e6 http://git.parisc-linux.org/?p=linux-2.6.git;a=commit;h=f70a979c843e4610edfb2a316648fe8ae8718f69 Thus please ignore my original patch proposal. It's not needed any more...
