Paul Gortmaker 70c7160619 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
 =========================================

Breno Leitao 71085ce828 ehea: Fix a checksum issue on the receive path
Currently we set all skbs with CHECKSUM_UNNECESSARY, even
those whose protocol we don't know. This patch just
add the CHECKSUM_COMPLETE tag for non TCP/UDP packets.

Thomas Klein 3fd09c45bf ehea: Detect 16GB hugepages for firmware restriction
All kernel memory which is used for kernel/hardware data transfer must
be registered with firmware using "memory regions". 16GB hugepages
may not be part of a memory region due to firmware restrictions.
This patch modifies the walk_memory_resource callback fn to filter
hugepages and add only standard memory to the busmap which is later
on used for MR registration.

Hannes Hering d4f12daf7b ehea: Fix memory hotplug support
This patch implements the memory notifier to update the busmap
instantly instead of rebuilding the whole map. This is necessary
because walk_memory_resource provides different information than
required during memory hotplug.

Due to stability issues in high load situations the HW queue handling
has to be changed. The HW queues are now stopped and restarted again instead
of destroying and allocating new HW queues.

Thomas Klein 44c8215257 eHEA: Introducing support vor DLPAR memory add
This patch adds support for DLPAR memory add to the eHEA driver. To detect
whether memory was added the driver uses its own memory mapping table and
checks for kernel addresses whether they're located in already known memory
sections. If not the function ehea_rereg_mrs() is triggered which performs
a rebuild of the mapping table and a re-registration of the global memory
region.

Hi Jeff,

I fixed the __iomem issue and tested the driver with sparse. Looks good so far.
Thanks for your effort.
