a.out: remove define-only CMAGIC, previously magic number
The last user was removed in 5.1 in
commit 08300f4402ab ("a.out: remove core dumping support")
but this is part of the UAPI headers, so this may want to either wait
until a.out is removed entirely, or be removed from the magic number doc
and silently remain in the header
A cursory glance on DCS didn't show any user code actually using this
value
Found with
grep MAGIC Documentation/process/magic-number.rst | while read -r mag _;
do git grep -wF "$mag" | grep -ve '^Documentation.*magic-number.rst:' \
-qe ':#define '"$mag" || git grep -wF "$mag" | while IFS=: read -r f _;
do sed -i '/\b'"$mag"'\b/d' "$f"; done ; done
