Pull MIPS update from Ralf Baechle:
"This is the MIPS update for 3.7.
A fair chunk of them are platform updates to the Cavium Octeon SOC
(which involves machine generated header files of considerable size),
Atheros ATH79xx, RMI aka Netlogic aka Broadcom XLP, Broadcom BCM63xx
platforms.
Support for the commercial MIPS simulator MIPSsim has been removed as
MIPS Technologies is shifting away from this product and Qemu is
offering various more powerful platforms. The generic MIPS code can
now also probe for no-execute / write-only TLB features implemented
without the full SmartMIPS extension as permitted by the latest MIPS
processor architecture. Lots of small changes to generic code."

The "IUDMA" engine used by bcm63xx_enet is also used by other blocks,
such as the USB 2.0 device. Move the definitions into a common file so
that they do not need to be duplicated in each driver.

No code changes. Recent patches have used the netdev style multi-line

The original hardware only supported 10M and 100M. Later versions
added 1G support. Here we update the driver to make use of this.
Also minor logic clean-ups for testing PHY registration error codes
and TX complete high water marks.

Pull infiniband changes from Roland Dreier:
"Second batch of changes for the 3.7 merge window:
- Late-breaking fix for IPoIB on mlx4 SR-IOV VFs.
- Fix for IPoIB build breakage with CONFIG_INFINIBAND_IPOIB_CM=n (new
netlink config changes are to blame).
- Make sure retry count values are in range in RDMA CM.
- A few nes hardware driver fixes and cleanups.
- Have iSER initiator use >1 interrupt vectors if available."
* tag 'rdma-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/roland/infiniband:
RDMA/cma: Check that retry count values are in range
IB/iser: Add more RX CQs to scale out processing of SCSI responses
RDMA/nes: Bump the version number of nes driver
RDMA/nes: Remove unused module parameter "send_first"
RDMA/nes: Remove unnecessary if-else statement

Currently, the InfiniBand stack does not support flow steering at the
verbs level -- the only usage of flow steering in the IB driver is for
L2 multicast attaches. We need to add the IB case to procedure
mlx4_QP_FLOW_STEERING_ATTACH_wrapper() to allow IPoIB to work on VFs
on ConnectX-3 when flow steering is enabled.
Currently, the IB case in mlx4_QP_FLOW_STEERING_ATTACH_wrapper() is missing,
so the procedure returns -EINVAL and IPoIB on VFs breaks.

Pull powerpc updates from Benjamin Herrenschmidt:
"Some highlights in addition to the usual batch of fixes:
- 64TB address space support for 64-bit processes by Aneesh Kumar
- Gavin Shan did a major cleanup & re-organization of our EEH support
code (IBM fancy PCI error handling & recovery infrastructure) which
paves the way for supporting different platform backends, along
with some rework of the PCIe code for the PowerNV platform in order
to remove home made resource allocations and instead use the
generic code (which is possible after some small improvements to it
done by Gavin).
- Uprobes support by Ananth N Mavinakayanahalli
- A pile of embedded updates from Freescale folks, including new SoC
and board supports, more KVM stuff including preparing for 64-bit
BookE KVM support, ePAPR 1.1 updates, etc..."

This patch fixes a bug in the method used for calculating the trigger
alignment for SDP0 when enabling a PPS output on the X540. The alignment math
wasn't properly taking into account the overflow cyclecounter, and was
misaligning the pin triggers so that two X540 devices synced properly had
mis-aligned SDP pins. This patch fixes the math to calculate the correct
seconds alignment for the PPS signal.

Commit d760fc37b0f74502b3f748951f22c6683b079a8e caused
1G functions to allocate rx rings which were 1/10 of the
size of 10G functions' rx rings.
However, it also caused 10G functions on 5771x boards to
allocate small rings, which limits their possible (default)
rx throughput. This patch causes all 10G functions to use
rings of intended length by default.

The config combination:
CONFIG_PCH_GBE=y
CONFIG_PCH_PTP=y
CONFIG_PTP_1588_CLOCK=m
doesn't work, because then you have a built-in kernel
object (the PCH_PTP code) referring to symbols in a
module (PTP_1588_CLOCK).
Fix this like IXGBE, by using "select PTP_1588_CLOCK"
instead of a "depends on".

Pull infiniband updates from Roland Dreier:
"First batch of InfiniBand/RDMA changes for the 3.7 merge window:
- mlx4 IB support for SR-IOV
- A couple of SRP initiator fixes
- Batch of nes hardware driver fixes
- Fix for long-standing use-after-free crash in IPoIB
- Other miscellaneous fixes"
This merge also removes a new use of __cancel_delayed_work(), and
replaces it with the regular cancel_delayed_work() that is now irq-safe
thanks to the workqueue updates.
That said, I suspect the sequence in question should probably use
"mod_delayed_work()". I just did the minimal "don't use deprecated
functions" fixup, though.

In the current driver, the SENSE_PORT firmware command is issued as a
"wrapped" command, but the command handling code doesn't have a
wrapper, so it will never do anything other than log an error message.
The latest ConnectX-3 2.11.500 firmware reports the SENSE_PORT
capability even in multi-function (SR-IOV) mode, so the driver will
try to issue the command.
At least until the driver has a proper wrapper for SENSE_PORT, make
sure we disable the command for multi-function devices.

Instead of having a hard-coded "PCI device ID != 0x1003" (which
obviously breaks as newer devices with ID != 0x1003 become available),
instead let's set a flag in our PCI device table for the older devices
where we're supposed to force using SENSE_PORT. This also avoids
enabling SENSE_PORT for virtual functions by mistake.

That way we can check flags later on, when we've finished with the
pci_device_id structure. Also convert the "is VF" flag to an enum:

On an SR-IOV master device, __mlx4_init_one() calls mlx4_init_hca()
before mlx4_multi_func_init(). However, for unlucky configurations,
mlx4_init_hca() might call mlx4_SENSE_PORT() (via mlx4_dev_cap()), and
that calls mlx4_cmd_imm() with MLX4_CMD_WRAPPED set.
However, on a multifunction device with MLX4_CMD_WRAPPED, __mlx4_cmd()
calls into mlx4_slave_cmd(), and that immediately tries to do
down(&priv->cmd.slave_sem);
but priv->cmd.slave_sem isn't initialized until mlx4_multi_func_init()
(which we haven't called yet). The next thing it tries to do is access
priv->mfunc.vhcr, but that hasn't been allocated yet.
Fix this by moving the initialization of slave_sem and vhcr up into
mlx4_cmd_init(). Also, since slave_sem is really just being used as a
mutex, convert it into a slave_cmd_mutex.

Previously, the structure of a guest's proxy QPs followed the
structure of the PPF special qps (qp0 port 1, qp0 port 2, qp1 port 1,
qp1 port 2, ...). The guest then did offset calculations on the
sqp_base qp number that the PPF passed to it in QUERY_FUNC_CAP().
This is now changed so that the guest does no offset calculations
regarding proxy or tunnel QPs to use. This change frees the PPF from
needing to adhere to a specific order in allocating proxy and tunnel
QPs.
Now QUERY_FUNC_CAP provides each port individually with its proxy
qp0, proxy qp1, tunnel qp0, and tunnel qp1 QP numbers, and these are
used directly where required (with no offset calculations).
To accomplish this change, several fields were added to the phys_caps
structure for use by the PPF and by non-SR-IOV mode:
base_sqpn -- in non-sriov mode, this was formerly sqp_start.
base_proxy_sqpn -- the first physical proxy qp number -- used by PPF
base_tunnel_sqpn -- the first physical tunnel qp number -- used by PPF.
The current code in the PPF still adheres to the previous layout of
sqps, proxy-sqps and tunnel-sqps. However, the PPF can change this
layout without affecting VF or (paravirtualized) PF code.

1. Allow only master to change node description.
2. Prevent AH leakage in send mads.
3. Take device part number from PCI structure, so that guests see the
VF part number (and not the PF part number).
4. Place the device revision ID into caps structure at startup.
5. SET_PORT in update_gids_task needs to go through wrapper on master.
6. In mlx4_ib_event(), PORT_MGMT_EVENT needs be handled in a work
queue on the master, since it propagates events to slaves using
GEN_EQE.
7. Do not support FMR on slaves.
8. Add spinlock to slave_event(), since it is called both in interrupt
context and in process context (due to 6 above, and also if
smp_snoop is used). This fix was found and implemented by Saeed

Normally, INIT_PORT and CLOSE_PORT are invoked when special QP0
transitions to RTR, or transitions to ERR/RESET respectively.
In SR-IOV mode, however, the master is also paravirtualized. This in
turn requires that we not do INIT_PORT until the entire QP0 path (real
QP0 and proxy QP0) is ready to receive. When the real QP0 goes down,
we should indicate that the port is not active.

P_Key change and guid change events are not of interest to all slaves,
but only to those slaves which "see" the table slots whose contents
have change.
For example, if the guid at port 1, index 5 has changed in the PPF, we
wish to propagate the gid-change event only to the function which has
that guid index mapped to its port/guid table (in this case it is
slave #5). Other functions should not get the event, since the event
does not affect them.
Similarly with P_Keys -- P_Key change events are forwarded only to
slaves which have that P_Key index mapped to their virtual P_Key table.

For IB ports, we paravirtualize the GUID at index 0 on slaves. The
GUID at index 0 seen by a slave is the actual GUID occupying the GUID
table at the slave-id index.
The driver, by default, requests at startup time that subnet manager
populate its entire guid table with GUIDs. These guids are then mapped
(paravirtualized) to the slaves, and appear for each slave as its GUID
at index 0.
Until each slave has such a guid, its port status is DOWN.
The guid table is cached to support special QP paravirtualization, and
event propagation to slaves on guid change (we test to see if the guid
really changed before propagating an event to the slave).
To support this caching, add capability to __mlx4_ib_query_gid() to
obtain the network view (i.e., physical view) gid at index X, not just
the host (paravirtualized) view.
