I looked at this bit more closely. CONFIG_EPOLL, CONFIG_SIGNALFD, and
CONFIG_TIMERFD are all default y and so actually get removed when the
next 'make savedefconfig' syncup will be done. Same thing for PROC_FS
and SYSFS.

Looking at the list of required options, FHANDLE is the only one which
needs to get enabled explicitly. Also, CONFIG_INOTIFY is actually a
stale entry that can be removed.

Based on this, I think the updated patch can be:

CONFIG_FHANDLE is required by systemd[1], which is the
default init system in more and more distributions.
So lets enable it for DaVinci platforms as well.

While at it, remove stale entry CONFIG_INOTIFY=y
