Hi,
Based on a thread with Jamie Lokier[1,2], this patch converts
several syscalls from <int> to <long>.
Jamie's list included sys_epoll calls, but Davide has
already modified those.
The rest of Jamie's list was:
sys_set_tid_address
sys_futex
sys_sched_setaffinity
sys_sched_getaffinity
sys_remap_file_pages
sys_lookup_dcookie
sys_pause
and my searching has only added
old_readdir
Comments?
Thanks,
~Randy
