      x86: setup_smep needs to be __cpuinit · 82da65da
      Linus Torvalds authored 
      The setup_smep function gets calle at resume time too, and is thus not a
pure __init function.  When marked as __init, it gets thrown out after
the kernel has initialized, and when the kernel is suspended and
resumed, the code will no longer be around, and we'll get a nice "kernel
tried to execute NX-protected page" oops because the page is no longer
marked executable.

      Remove prefetch() from <linux/skbuff.h> and "netlabel_addrlist.h" · a1e4891f
      Linus Torvalds authored 
      Commit e66eed65 ("list: remove prefetching from regular list
iterators") removed the include of prefetch.h from list.h.  The skbuff
list traversal still had them.

Quoth David Miller:
  "Please just remove the prefetches.

  Those are modelled after list.h as I intend to eventually convert
  SKB list handling to "struct list_head" but we're not there yet.

  Therefore if we kill prefetches from list.h we should kill it from
  these things in skbuff.h too."

      Add appropriate <linux/prefetch.h> include for prefetch users · 70c71606
      Paul Gortmaker authored 
      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
