Commit d0418bb7123f44b23d69ac349eec7daf9103472f (net: sh_eth: Add eth support
for R8A7779 device) was a failed attempt to add support for one of members of
the R-Car SoC family. That's for three reasons: it treated R8A7779 the same
as SH7724 except including quite dirty hack adding ECMR_ELB bit to the mask
in sh_eth_set_rate() while not removing ECMR_RTM bit (despite it's reserved in
R-Car Ether), and it didn't add a new register offset array despite the closest
SH_ETH_REG_FAST_SH4 mapping differs by 0x200 to the offsets all the R-Car Ether
registers have, and also some of the registers in this old mapping don't exist
on R-Car Ether (due to this, SH7724's 'sh_eth_my_cpu_data' structure is not
adequeate for R-Car too). Fix all these shortcomings, restoring the SH7724
related section to its pristine state...

WOL is broken because the magic packet status bit is getting set rather
than the enable bit. The PMT interrupt is not getting serviced because
the PMT interrupt is also enabled on the global interrupt, but not
cleared by the global interrupt and the global interrupt is higher
priority. This fixes both of these issues to get WOL working.
There's still a problem with receive after resume, but at least now we
can wake-up.

If skb allocation for the rx ring fails repeatedly, we can reach a point
were the ring is empty. In this condition, the driver is out of sync with
the h/w. While this has always been possible, the removal of the skb
recycling seems to have made triggering this problem easier.

This patch enables RX of jumbo frames for LAN7500.
Previously the driver would transmit jumbo frames succesfully but
would drop received jumbo frames (incrementing the interface errors
count).
With this patch applied the device can succesfully receive jumbo
frames up to MTU 9000 (9014 bytes on the wire including ethernet
header).

The current Tilera boot infrastructure now provides the initramfs
to Linux as a Tilera-hypervisor file named "initramfs", rather than
"initramfs.cpio.gz", as before. (This makes it reasonable to use
other compression techniques than gzip on the file without having to
worry about the name causing confusion.) Adapt to use the new name,
but also fall back to checking for the old name.
Cc'ing to stable so that older kernels will remain compatible with
newer Tilera boot infrastructure.

Currently if either arp_interval or miimon is disabled, they both get
disabled, and upon disabling they get executed once more which is not
the proper behaviour. Also when doing a no-op and disabling an already

The MAC's interrupt mask is set only for Transmit FIFO Underruns.

A result of ENOENT from a read request for an object that's part of
an rbd image indicates that there is a hole in that portion of the
image. Similarly, a short read for such an object indicates that
the remainder of the read should be interpreted a full read with
zeros filling out the end of the request.
This behavior is not correct for objects that are not backing rbd
image data. Currently rbd_img_obj_request_callback() assumes it
should be done for all objects.
Change rbd_img_obj_request_callback() so it only does this zeroing
for image objects. Encapsulate that special handling in its own
function. Add an assertion that the image object request is a bio
request, since we assume that (and we currently don't support any
other types).
This resolves a problem identified here:
http://tracker.ceph.com/issues/4559
The regression was introduced by bf0d5f503dc11d6314c0503591d258d60ee9c944.

This patch fixes a regression introduced in v3.8-rc1 code where a failed
target_check_reservation() check in target_setup_cmd_from_cdb() was causing
an incorrect SAM_STAT_GOOD status to be returned during a WRITE operation
performed by an unregistered / unreserved iscsi initiator port.
This regression is only effecting iscsi-target due to a special case check
for TCM_RESERVATION_CONFLICT within iscsi_target_erl1.c:iscsit_execute_cmd(),
and was still correctly disallowing WRITE commands from backend submission
for unregistered / unreserved initiator ports, while returning the incorrect
SAM_STAT_GOOD status due to the missing SAM_STAT_RESERVATION_CONFLICT
assignment.
This regression was first introduced with:
commit de103c93aff0bed0ae984274e5dc8b95899badab
Author: Christoph Hellwig <hch@lst.de>
Date: Tue Nov 6 12:24:09 2012 -0800
target: pass sense_reason as a return value
Go ahead and re-add the missing SAM_STAT_RESERVATION_CONFLICT assignment
during a target_check_reservation() failure, so that iscsi-target code
sends the correct SCSI status.
All other fabrics using target_submit_cmd_*() with a RESERVATION_CONFLICT
call to transport_generic_request_failure() are not effected by this bug.

programs"
This reverts commit 186930500985 ("mm: introduce VM_POPULATE flag to
better deal with racy userspace programs").
VM_POPULATE only has any effect when userspace plays racy games with
vmas by trying to unmap and remap memory regions that mmap or mlock are
operating on.
Also, the only effect of VM_POPULATE when userspace plays such games is
that it avoids populating new memory regions that get remapped into the
address range that was being operated on by the original mmap or mlock
calls.
Let's remove VM_POPULATE as there isn't any strong argument to mandate a
new vm_flag.

John W. Linville says:
====================
Please excuse this larger-than-I-would-like pull request intended
for the 3.9 stream. There are a number of late-breaking fixes,
including a revert...
Regarding the mac80211 bits, Johannes says:
"I have two tracing fixes (one from Vladimir), two fixes for P2P device
crashes, a fix for a BSS memory leak/lost update problem and a fix from
Ben for a scanning issue in mac80211. It's a little on the large side
because one of the P2P device problems required a bit much locking work,
but I've run through all the different scenarios (wext/nl80211,
p2p-device/station interface, ifdown/rfkill) to verify locking with
lockdep."
As for the iwlwifi bits, Johannes says:
"I have three little fixes to the driver from Emmanuel. One addresses a
small bug Ben Hutchings found during the stable review process and two
address some warnings in the driver when RF-Kill is asserted."
Along with those...
Avinash Patil fixes an mwifiex bug cause by failing to process a sleep
command due to bad SKB manipulation when going into power saving mode.
Colin Ian King avoids a null pointer dereference in iwl4965.
Dan Williams officially announces that he has dropped maintainership
of the libertas driver.
Iestyn C. Elfick adds a work-around to avoid b43 DMA transmision
sequence error that would lead to a device reset.
Luis R. Rodriguez avoids an ath9k warning by not queueing a work item
while going to suspend mode.
Rafał Miłecki provides a pair of b43 N-PHY fixes related to RSSI
calibration.
Finally, I revert "brcmsmac: support 4313iPA" because it has been
reported in many places to cause problems with the already supported
4313ePA devices.

The core has a bit for swapping packet data endianism.
Reset default from Cadence is off. Xilinx however, who uses this core on the
Zynq SoCs, opted for on.
Force it to off. This shouldn't change the behaviour for current users of the
macb, but enables usage on Zynq devices.

At least in the cadence IP core on the Xilinx Zynq SoC the TCOMP/RCOMP flags
are not auto-cleaned. As these flags are evaluated, they need to be cleaned.

Jeff Kirsher says:
====================
This series contains updates to e1000e, ixgbe and ixgbevf.
Majority of the changes are against e1000e (from Bruce Allan).
Bruce adds additional error handling on PHY register access, as
well as improve slow performance on 82579 when connected to a
10Mbit hub. In addition, fixes LED blink logic for cathode
LED design. Most notable is added EEE support which is enabled
by default and the added support for LTR on I217/I218.
The ixgbe and ixgbevf from Greg Rose changes the VM so that if a user
does not assign a MAC address, the MAC address is set to all zeros
instead of a random MAC address. This ensures that we always know when
we have a random address and udev won't get upset about it.

Included changes:
- A fix for the network coding component which has been added within the last
pull request (so it is in linux-3.10). The problem has been spotted thanks to
Fengguang Wu's automated daily checks on our tree.
- Implementation of the RTNL API for virtual interface creation/deletion and slave
manipulation
- substitution of seq_printf with seq_puts when possible
- minor cleanups

Some network drivers use a non default hard_header_len
Transmitted skb should take into account dev->hard_header_len, or risk
crashes or expensive reallocations.
In the case of aoe, lets reserve MAX_HEADER bytes.
David reported a crash in defxx driver, solved by this patch.
