Helge Deller 44a4c9e443 parisc: Add wrapper syscalls to fix O_NONBLOCK flag usage ... The commit 75ae04206a ("parisc: Define O_NONBLOCK to become 000200000") changed the O_NONBLOCK constant to have only one bit set (like all other architectures). This change broke some existing userspace code (e.g. udevadm, systemd-udevd, elogind) which called specific syscalls which do strict value checking on their flag parameter. This patch adds wrapper functions for the relevant syscalls. The wrappers masks out any old invalid O_NONBLOCK flags, reports in the syslog if the old O_NONBLOCK value was used and then calls the target syscall with the new O_NONBLOCK value.
