Add appropriate <linux/prefetch.h> include for prefetch users
After discovering that wide use of prefetch on modern CPUs
could be a net loss instead of a win, net drivers which were
relying on the implicit inclusion of prefetch.h via the list
headers showed up in the resulting cleanup fallout. Give
them an explicit include via the following $0.02 script.
=========================================
#!/bin/bash
MANUAL=""
for i in `git grep -l 'prefetch(.*)' .` ; do
grep -q '<linux/prefetch.h>' $i
if [ $? = 0 ] ; then
continue
fi
( echo '?^#include <linux/?a'
echo '#include <linux/prefetch.h>'
echo .
echo w
echo q
) | ed -s $i > /dev/null 2>&1
if [ $? != 0 ]; then
echo $i needs manual fixup
MANUAL="$i $MANUAL"
fi
done
echo ------------------- 8\<----------------------
echo vi $MANUAL
=========================================

non-network drivers and the fib_trie.c case - Linus ]
