Ok, even without patching vanilla kernel with grsecurity or any other hardening
patches, /proc/kcore could be disabled in kernel config as a security
precaution.

>From my perspective I can understand different scenarios where this file is
missing. Though I can not understand you desire to keep broken symlinks in
/dev/ 'just because'. Does udev really need this symlink to work properly? Or
maybe some other applications need it? Removing this broken symlink will
trigger EACCES rather than ENOENT so my guess is no harm for applications would
be done.
