Change details:
- Add debugfs support to obtain firmware trace, saved firmware trace on
an IOC crash, driver info and read/write to registers.- debugfs hierarchy:
bna/pci_dev:
where the pci_name corresponds to the one under /sys/bus/pci/drivers/bna- Following are the new debugfs entries added:
fwtrc: collect current firmware trace.
fwsave: collect last saved fw trace as a result of firmware crash.
regwr: write one word to chip register
regrd: read one or more words from chip register.
drvinfo: collect the driver information.Signed-off-by: Krishna Gudipati

This reverts commit e5671dfae59b165e2adfd4dfbdeab11ac8db5bda.
After a follow up discussion with Michal, it was agreed it would
be better to leave the kmem controller with just the tcp files,
deferring the behavior of the other general memory.kmem.* files
for a later time, when more caches are controlled. This is because
generic kmem files are not used by tcp accounting and it is
not clear how other slab caches would fit into the scheme.We are reverting the original commit so we can track the reference.
Part of the patch is kept, because it was used by the later tcp
code. Conflicts are shown in the bottom. init/Kconfig is removed from
the revert entirely.Signed-off-by: Glauber Costa

A known Out Of Order (OOO) problem hurts SFQ when timer changes
perturbation value, since all new packets delivered to SFQ enqueue might
end on different slots than previous in-flight packets.With round robin delivery, we can thus deliver packets in a different
order.Since SFQ is limited to small amount of in-flight packets, we can rehash
packets so that this OOO problem is fixed.This rehashing is performed only if internal flow classifier is in use.
We now store in skb->cb[] the "struct flow_keys" so that we dont call
skb_flow_dissect() again while rehashing.Signed-off-by: Eric Dumazet

The NETIUCV device driver allows to connect a Linux guest on z/VM to
another z/VM guest based on the z/VM communication facility IUCV.
Multiple output paths to different guests are possible, as well as
multiple input paths from different guests.
With this feature, you can configure multiple point-to-point NETIUCV
interfaces between your Linux on System z instance and another z/VM

module_param(bool) used to counter-intuitively take an int. In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.It's time to remove the int/unsigned int option. For this version
it'll simply give a warning, but it'll break next kernel version.(Thanks to Joe Perches for suggesting coccinelle for 0/1 -> true/false).

This patch adds the ethtool callbacks necessary to change the rss
indirection table from userspace. Should the number of interrupts
change (e.g. across a close / open call, or through a reset) and
any one of the indirection table values fall out-of-range, the driver
will reset the indirection table to a default layout.[Integrated many suggestions made by Ben Hutchings.]
